  We are new. In particular, it concerns

  liquid, antistatic and softening detergents

  My tissues, preferably detergent detergent compositions, which contain a detergency builder, which contain

  also wise a method for washing and drying laundry that provides soft and static-free laundry or low electrostatic charge despite the fact that it was subjected to

  a conventional drum drying operation.

  Synthetic organic detergent compositions

  strengthened ticks are currently the

  choice of choice for washing dirty laundry. These compounds

  have been exceptionally effective in laundering fabric articles made of synthetic and / or natural fibrous materials, whether they have been stained by oily, protein or clay soils, these three types of soiling being those which are meets most often in domestic laundry, and which are fairly representative of the normally appearing stains that are present on the laundry

  dirty current. With the replacement of soap in

  washing with synthetic organic detergents

  the softening effect of soap (usually due to an insoluble soap which settles on the fibers of the fabric constituting the linen) has been lost and in particular

  presence of certain inorganic salts adjuvants deter-

  In spite of this, linen often becomes unpleasant to the touch, rough and stiff (or cardboardy). For years, we have

  knows that bentonite, when added to

  synthetic organic detergent positions based on anionic detergents, could soften the laundry and make

  thus the detergent compositions thus modified

tables for the consumer.

  Although we have known for years

  liquid detergent compositions, this is only relative-

  recently that reinforced detergent compositions

  for heavy laundering work in a loose state

  quide, have become popular. These compositions, in par-

  especially when they contain solids in

  suspension, are sometimes thickened to prevent a sepa-

  components during storage. Bentonite of the gelling type, such as the bentonite of western

  United States of America or Wyoming, presents

  thickening and, moreover, it constitutes an

wrinkling tissue.

  With the advent of synthetic polymer fibers,

  clothes and other articles made from such fibers and from mixtures of such synthetic materials with natural fibers, such as

  cotton / polyester blends, and with the increasing use of

  automatic tumble dryers, which are almost all of the drum drying type, it has been found that dried laundry often accumulates electrostatic charges.

  which caused a harmful clash,

  Normal washing and folding of the linen for storage. It has been known for years that cationic compounds such as quaternary ammonium salts, e.g.

  di- (higher alkyl) -di- (lower alkyl) ammo-

  nium, are able to act as antistatic agents (anti-

  stats) by reducing static charges on the tissues and

  by preventing static snapping. During a laundering

  softening agent, these halides are normally added

  rinse water during a wash cycle and not in a detergent composition or wash water,

  because they react chemically with the anionic detergents

  which are the most frequently used detergents

  in synthetic organic detergent compositions.

  This reaction, which can be expected to be more serious in liquid detergents than in

  in particulate matter, would reduce the detergency of the com-

  detergent position and could form reaction products

  unwanted deposits that could be deposited on the laundry during washing, producing grease or dirt stains. In recent years, cationic compounds such as quaternary ammonium halides have been incorporated into reinforced detergent compositions, particularly compositions

  particulate detergents, in which they do not react

  They are not chemically detrimental to anionic detergents during storage, but react to some degree with them in the wash water. Although such compositions exert an antistatic effect and

  reduce static cling of washed laundry, it has been noted that

  that the detergency of the compositions in the

  what these compounds are present is less than that

  of the base composition not containing the antistate.

  In U.S. patent application 674 194 and the corresponding French application 83 12 817 filed August 3, 1983, is described the use of N- (primary alkyl)

  isostearamides as antistatic agents in

  detergent substances, and it is stated that these isostearamines do not react detrimentally with detergents.

  anionic in the compositions or in the wash water.

  In these requests, it is stated that isostaramids

  described can be combined with bentonite and

  with detergent particulate

  give a wash water with anti-

  static and fabric softening, so that the laundry washed with this water is flexible and free of undesirable static snagging. The present application describes in detail liquid detergent compositions containing both

  bentonite and an antistat of the N-type isostearamide

  substituted, and describes the advantageous effects thereof, which include obtaining washed laundry having satisfactory flexibility (particularly woven or other fabric napkins from

  natural organic plant fibers, for example -

  cottons and terry cloths, obtaining washed laundry with little or no static

  detergency and the absence of compound stains

  ternary on washed laundry. We notice in particular

  the unexpected improvement of the antistatic effect of

  stearamide N- (primary aliphatic) which is due to the pre-

  the presence of bentonite in the detergent composition

  the anionic detergent compositions of the invention containing bentonite and coconut alkyl isostearamide (CISA) are used, whereas when quaternary ammonium salts are used as antistats, the foaming power is used. found to be diminished, apparently because of the

  reaction of the quaternary salt with the anionic detergent.

  In addition, yellowing or similar alteration of

  4distat and the repositioning of the blemishes are reduced, compared to those resulting from the use, for any antistatic property to which it can contribute, of a quaternary ammonium halide with anionic detergent in other compositions

reinforced detergents.

  According to the present invention, an antistatic and fabric softening liquid detergent composition comprises a detersive portion of a detergent

  synthetic organic matter, a proportion with an effect of

  bentonite fabric and an antistatic proportion of a higher aliphatic isostearamide antistatic agent in an aqueous medium. Normally, the active detergent component of the described detergent composition is an anionic detergent (which is capable of reacting with a quaternary ammonium salt), and the composition

  detergent is a reinforced composition containing an additive

  detergent for the detergent, for example

  sodium polyphosphate, sodium carbonate, NTA or a polyacetal carboxylate, or other detergency builder

  appropriate, or a mixture of such adjuvants. In a composition

  preferred liquid detergent, isostearamide is

  dissolved, emulsified or dispersed and the bentonite is pre-

  in the form of a dispersion in the finely divided state,

  its particles preferably being of a smaller size than

  to 0.074 mm (U.S. mesh N 200), for example 0.037 to 0.074 mm, such as about 0.044 mm. If desired, bentonite and / or Nisostearamide may be added to the wash water before, after or at the same time as the rest

  components of the liquid detergent composition described.

  The synthetic organic anionic detergent

  detergent compositions is normally

  killed by one or more sulphonated and / or sulphonated lipophilic materials having an alkyl chain having 8 to 20 carbon atoms, preferably 10 to 18, and more preferably

  12-16, and is preferably a particular mixture of

  to bind two types of such detergents. Although various water-soluble salt-forming cations can be used to form the desired soluble sulfonated and sulfonated detergents, including ammonium, a lower alkanol amine

  potassium and, very advantageously, this cation is sodium.

  Of the various anionic detergents which are useful in the practice of the present invention,

  linear higher) benzene-sulfonates whose alkyl chain

  It comprises from 10 to 18 carbon atoms, preferably from 12 to 16 and more preferably from 12 to 14, for example dodecyl and tridecyl, are considered as the most appropriate, often in combination with a salt of an acid.

  sulfuric polyethoxylated higher fatty alcohol. The alcohol-

  ether sulphate is normally derived from a linear higher alcohol (eg, fatty alcohol) having 10 to 18, preferably 12 to 15, carbon atoms, and the degree of ethoxylation is

  generally from 1 to 15 ethoxy groups per mole, preferably

  2 to 10, more preferably 2 to 5, for example 3. Among other synthetic detergents, monoglyceride-sulphates, (higher fatty alcohol) sulphates, paraffin-sulphonates and olefin sulphonates, the alkyl group of all these are also useful. compounds generally having 10 to 18 carbon atoms. Some of these alkyl groups may be slightly branched (which is not preferred), yet still within the described range of

carbon chain.

  Although (linear higher alkyl) benzene-

  sulfonates and sulfated polyethoxylated higher alcohols,

  in the form of sodium salts, namely anionic detergents

  In the preferred embodiments of the present invention, mixtures of such detergents may be used with other sulfonates and sulfates of this type containing different cations as well as mixtures of such detergents with others, such as (fatty alcohol) sulphates. In some cases, only relatively small or small proportions will be present

  linear alkyl benzene sulfonates and polyethoxylates

  sulphates or the synthetic organic anionic detergent

  may be a mixture of other anionic detergents

  Of the types described, it is also possible to use various

  very anionic detergents, such as those that are well

  known in practice and which are described in various publications

  annual publications entitled McCúchèehéô sDàterCeEtà and Emulsifiers, for example that published in 1969

  Although the present invention is aimed primarily at

  anionic detergent compositions with

  antistatic properties, the advantageous results mentioned here can also be obtained with compositions

  containing other types of synthetic organic detergents

  often with anionic detergents, eg nonionic and amphoteric detergents. Non-materials

  mentioned ionic and amphoteric

  in minor proportions only, if present, and in general their proportion will be limited to no more than half of that of the synthetic anionic organic detergent. Nonionic detergents-which one

  preferable are the condensation products of the oxide of

  ethylene and higher fatty alcohols, such as the condensation products of higher fatty alcohols having 12 to 18 carbon atoms with 3 to 20 moles of ethylene oxide, preferably the higher fatty alcohol condensation products having 12 to 15 carbon atoms with 5 to 15

moles of ethylene oxide.

  The detergent is preferably reinforced with a detergency builder so that it has greater cleaning power and should be suitable for "heavy" cleaning work. Detergent adjuvants useful for the compositions of the invention include polyphosphates such as sodium tripolyphosphate and tetrasodium phosphate, sodium carbonate, sodium bicarbonate, sodium sesquicarbonate, sodium silicate, and the like. (Na2O: SiO2 = 1.6 to 3.0, preferably 1: 2.4), NTA, sodium citrate, sodium gluconate,

  borax, other borates, zeolites, polyacetal

  carboxylates and other detergency builders known in the detergent art. Sodium silicates can often be suppressed because, in liquid media, they

  can react with carbonate and zeolite

  lite used as builders, and with bentonite, forming unfavorably thick products

or coagulated or precipitates.

  When detergency additives are used

  of the zeolite type, these usually have the formula -

  (Na 2 O) x (Al 2 O 3) y (SiO 2) w H 2 O ox is 1, y is from 0.8 to 1.2, preferably about 1, z is from 1.5 to 3.5. preferably 2 to 3 or about 2, and w is 0 to 9, preferably 2.5 to 6. These. zeolites are cation exchangers and have ion exchange power

  calcium from about 200 to 400 milligrams equivalent or

  vantage of hardness reduced to calcium carbonate per gram

  me. They are very often hydrated at a rate of 5 to 30% moisture, preferably 10 to 25%, for example about%. Zeolite A is preferred (X and Y are also useful) and, for this zeolite, type 4A is particularly preferred. The particle dimensions of the zeolite (s) are generally from 0.037 to 0.149 mm (U.S. 400 mesh), preferably from 0.044 to 0.074 or 0.105 mm, but

  their final dimensions will be less than one micrometer.

  The various zeolites are described in detail in the book Zeolite Molecular Sieves, by Donald W. Breck, published in 1974 by John Wiley & Sons, especially on pages

747-749.

  When polyacetal carboxylates are

  they can be considered as those described in US-A-4,144,226 and may be manufactured

  by the process mentioned therein. A representative example

  tif of such a product is represented by the formula:

R1 - (CHO) - R2

COOM

  M is selected from alkali metals, ammonium, alkyl groups of 1 to 4 carbon atoms and tetraalkylammonium and alkanolamine groups which have from 1 to 4 carbon atoms in their alkyl moiety, n is on average equal to 4 at least, and R1 and R2 are any chemically stable groups that stabilize the polymer against

  rapid depolymerization in alkaline solution. Befor-

  Preferably, the polyacetal carboxylate is one of those in which M is an alkali metal, for example sodium, n is 20 to 200, R 1 is represented by:

  normally between 2000 and 20 000, preferably between

  between 3500 and 10 000, and even better between 5000

  and 9000, for example about 8000.

  Although the preferred polyacetal carboxylates have been described, it is evident that they can be replaced

  totally or partially by other polyacetal carbons

  The chain termination groups described in the Monsanto patents in question, in particular US-A-4,144,226, may be used, provided they have the requisite stabilizing properties, which allow the detergency builders mentioned to be depolymerized in acidic media, which facilitates their biodegradation in the residual currents, but maintain their stability in alkaline media such as

  When it is desired to avoid the presence of phosphorus

  in the detergent composition, it is possible to eliminate

  Polyphosphate-type detergents of the present formulations, in which case it is preferable to use other phosphate-free detergency builders, such as those mentioned herein. The combinations of zeolite and polyacetal carboxylate are alternatives

  isostearamides in detergent compositions (but without bentonite), are described in United States Patent Application No. 674,899 entitled "Antistatic Built Synthetic Organic Detergent Composition", filed by Gary M. Freeman on November 26, 1984. Sodium salts these detergency builders are preferably used, but they can be replaced at least partially by

  alkali metal salts and other soluble salts.

  lyte to product and wash water when this is

  considered as desirable, and they can also serve

for other functional purposes.

  The antistatic agent of choice in the implementation

  practice of the present invention is N-coco-isostea

  ramide. This antistatic agent is an amide that can be

  chemically derived from isostearic acid and coconut

  amine by the condensation reaction shown below

  O, Isostearic acid, RC-OH, is a saturated fatty acid of the formula C17H35COOH, which is a complex mixture of isomers, mainly of the methyl branched series, which isomers are mutually soluble and substantially inseparable. Although such an acid has uses analogous to those of stearic or oleic acids, it is considered that it is far superior to these

  materials for the manufacture of effective antistatic agents

  which are suitable for incorporation into

  liquid detergent positions, based on organic detergent

  anionic synthetic nique, of the plaintiff. The copra

  amine is an aliphatic amine in which the group

  Aliphatic is derived from coconut oil. We can also

  use other primary aliphatic amines,

  preferably (higher alkyl) amines-having 7 to 18-

  carbon atoms in the alkyl moiety, for example R'NH2, or R 'is such an upper alkyl group, but the

  coconut amine produces an N-alkyl isostearamide whose

  properties are best for incorporation into detergent compositions. This isostearamide is called CISA. While CISA is the most preferred antistatic agent, the invention contemplates, in its broader aspects, the use of other N-aliphatic isostearamides such as those derived from aliphatic amines.

  containing up to 20 carbon atoms, preferably

  7 to 18 carbon atoms, of which the aliphatic

  may or may not be hydrogenated, provided that the amides obtained have a sufficient antistatic effect in

  the described use. Some examples are the N-

  alkylisostearamides of 7 to 18 carbon atoms, for example

  of N-decylamine, N-octylamine and those derived from N-tallow amine. However, it is considered that CISA is the most interesting of the Nalkylisostearamids with regard to

  antistatic activity and, therefore, when

  If the other isostearamides are used, this use will preferably be with CISA, and the proportion of the other isostearamide (s) will preferably be minor, relative to CISA. In some cases the hydrogen atom of the amide nitrogen may be replaced by appropriate radicals, for example lower alkyl, such as methyl, provided that the desired antistatic effect is still obtained, but it has been found that that tertiary isostearamids have in

  general little antistatic activity.

  The bentonite used is preferably a ben-

  tonite from Wyoming or western United States of America

  having a puff rate of 3 to 15 ml / gram, preferably

  from 7 to 15 ml / g, and its viscosity, at a concentration of 6% in water, is generally from 3 to 30 mPa.s,

  preferably from 8 to 30 mPa.s. Swelling bentonites used

  such materials are sold under the trade name Ore Colloid, as industrial bentonite, by Benton Clay Company, a subsidiary of Georgia Kaolin Co. These materials were previously marketed under the trademark THIXO-JEL by this company. These are selectively exploited and enriched bentonites, and those considered to be most useful are available under the Mineral Colloid designation 101, etc., and correspond to those previously sold under the

  trademarks THIXO-JEL N 1, 2, 3 and 4. These ma-

  have a pH (6% concentration in water) of 8 to 9.4, a maximum free moisture content of approximately 8% and densities of approximately 2.6, and for the quality sprayed, a proportion of about 85% passes through a 0.074 mm (US N 200) mesh screen. A bentonite equivalent to this bentonite is that sold as Bentonite Clay AEG 325 by American Colloid Co., which is essentially 0.044 mm in size (U.S. mesh size).

  The enriched Wyoming bentonite is preferred as a component of the compositions of the present invention,

  but other bentonites are also useful, especially

  when they constitute only a half

  of the bentonite used. It has been found that at least about 2%, preferably at least 4%, and more preferably 5% or more, up to about 8%, water must be present.

Among the various additives that may be present in the liquid detergents of the invention, mention may be made of dyes such as soluble or colloidal dyes and pigments, perfumes, enzymes, stabilizers, thickeners, solvents, dispersants, activators, brighteners, bleaches, buffers, fungicides, germicides, foaming agents, defoamers and flow promoters. Among the additives, detergency builders and fillers, there may be mentioned, unless they are included in other classes than mentioned, various other components or impurities that are sometimes present in the components of the compositions. For example, it is known that sodium carbonate and water are often present with polyacetal carboxylate in Builder U, a

  product which is a current source of polyacetal-carboxy-

  late. The proportions of the essential components of the detergent compositions are such as to render them effective for the purposes for which the compositions are intended. Thus, the synthetic organic detergent or the mixture of such detergents is present in the liquid detergent in a detersive proportion, the bentonite is present in a softening proportion.

  Static is present in a proportion with antistatic effect.

  In the case where there is a detergency builder or a

  In addition to such adjuvants, as is the case in most detergent compositions of the present invention, it is present in a detergent strengthening effect. The proportions described are normally 3.5 to 25% of the liquid detergent, preferably 3 to 15% of linear (higher alkyl) sodium benzenesulfonate, and more preferably about 5 to 13% thereof, e.g. about 9% of linear (alkyl) sodium benzenesulfonate having 12 to 13 or 14 carbon atoms, with 0.5 to 10% of (higher fatty alcohol) -polyethoxyether sodium sulfate in which the alcohol comprises 8 to 18 carbon atoms and the polyethoxyether comprises 1 to 15 moles of ethylene oxide per mole, preferably 1 to 5% of (higher primary alcohol) polyethoxy-ether-sodium sulfate having 12 to 15 carbon atoms in the alcohol moiety and 2-4 or 6 moles of ethylene oxide per mole, for example about 2%. The detergency builder for the liquid detergent, which can be a mixture of adjuvants

  of detergents, is normally 5 to 40% of the

* sodium carbonate0 and better yet it is a combination of

  binder of 8 to 14% of sodium tripolyphosphate and 3 to 7% of sodium carbonate, for example about 11% and 4% respectively. Bentonite is normally

  3 to 20% of the liquid detergent composition, preferably

  5 to 20%, and more preferably about 5 to 15%, for example about 12%, the isostearamide type antistat

  normally constituting 1 to 10% of the deter-

  liquid, preferably 1 to 7% thereof, and more preferably about 3 to 7%, for example about 5%.

  in water or in an aqueous medium liquid detergent is gener-

  from 3 to 80%, preferably from 40 to 70%, more preferably from about 45 to 65%, for example about 55%.

  In the liquid detergent composition, the

  bentonite to the antistate is generally one part antistate for 1 to 20 parts bentonite, preferably 1: 1.5 to 4, and more preferably 1: 2 to 3, by

Example 1: 2.4.

  To make the detergent compositions

  Of the invention, the various components of the final product are normally simply mixed together and stirred or otherwise subjected to sufficient agitation.

  to produce a uniform liquid product. The order of ad-

  components may be determined in such a way as to

  promote optimal mixing. The quantity of

  quide will normally be sufficient at all times to

  mass caking of solids with

  insufficient portion of the liquid, and to prevent the formation of lumps that could eventually be

  difficult to disperse. Fine particulate components

  divided, both soluble and insoluble, are gener-

  mixed with a portion of the aqueous medium, and then the remainder of the aqueous medium is used to dilute

  mixing, according to the normal manufacturing techniques.

  The mixture may be subjected to a passage in a homoge-

  neiser to facilitate the dispersion of the components and avoid a separation thereof and in some cases the composition may contain hydrotropic materials

  such as cumene-sodium sulfonate and xylene-

  sodium sulphonate, normally in small proportions, for example up to about 1 or 2%, to help the liquid composition to maintain its homogeneity. Similarly, solvents such as ethanol and ethylene glycol or other appropriate glycols can be used to

  solubilize the components of the composition, and these solubilizing

  also help prevent product freezing

  when subjected to cold weather conditions.

  The various solid components of the liquid detergent composition which are used are normally in the form of

  finely divided particles, in order to promote a disso-

  easy lution (when soluble) or easy dispersion in the aqueous medium. In general, powdered materials have particle sizes less than

  0,074 or 0,105 mm, and normally these particular dimensions

  are between 0.037 and 0.105 mm, often and preferably between 0.037 and 0.074 mm, for example about 0.044 mm. With readily soluble components such as sodium carbonate, sodium tripolyphosphate and synthetic organic detergents, the particle sizes may be at the upper ends of the ranges indicated, or even above, but for insoluble or slowly dissolving materials. such

  zeolites and clays, the smallest

  Particles are usually more beneficial.

  In accordance with the present invention, the laundry is washed with a liquid detergent composition described in wash water, and this laundry is

  easily carried out according to normal processes of

  chopping, using conventional equipment and

  normal washing concentrations or deter-

  liquids, and the washing gives a clean cloth which is soft to the touch and does not present a disturbing static cling even in the case where there are proportions

  synthetic materials such as poly-

  esters, for example Dacron, and polyamides, for example nylon. The washing water used may be water of

  city-normal and the detergent compositions of the invention

  are effective even in the case of a hardness as high as 300 ppm, expressed in calcium carbonate, and sometimes even higher. Normally, there water hardness is a mixed hardness due to magnesium and calcium ions,

  most of it is usually calcium. Preferably

  the washing water has a hardness of not more than 250

  ppm and the normal city water used has

  from 20 to 150 or 200 ppm, for example about 50 or ppm. The compositions of the present invention can be used with wash water at any temperature (10 to 90 C) and are effective even with

  washing water at the lowest temperatures, for example

  around room temperature. According to

  European practice, compositions can be used

  in wash waters at temperatures close to boiling, for example 70 to 90 C, but in the

  American practice, lower temperatures are used.

  EXTERIOR. Particularly good results are obtained according to the American washing practice, using the compositions of the present invention in wash water at temperatures of 10 to 50 ° C, preferably 50 ° C, for example about 40 ° C. The concentration of the detergent composition in the wash water may be varied depending on the case, but normally it is 0.1 to 0.5% by weight, preferably 0.1 to 0.4%,

  and more preferably from about 0.15 to 0.25%, for example

  0.2% viron. Thus, one can use a half-cup or g of liquid detergent, often with a density of about 1.1 to 1.3 g / ml, for example 1.2 g / ml, in a washing machine containing about 65 liters of water, to wash a normal load, which is about 2.7 to 4.5 kg, for example about 3.6 kg of dry laundry. In some cases, for example if it is desired that the liquid detergent be used in larger or smaller volumes by

  load, it is possible to increase or decrease

  the concentrations of the components in the composi-

  liquid, within practical limits. -

  Conventional washing machines and normal washing cycles of such machines can be used, or washing machines for industrial or commercial use can be used. The washing of the laundry is carried out in a normal cycle over a period of about 2 to 30 minutes, for example 5 to 20 minutes, for example about 10 minutes, depending on the degree of dirtiness of the laundry and the nature of the fabric. At the end of the washing cycle, the laundry is rinsed automatically, and it is then dried in an automatic tumble dryer in which it is tumbled

  while being subjected to the passage of drying air.

  Instead of a liquid detergent containing the

  In accordance with one embodiment of the present invention, the fabric and antistatic composition of the invention can be prepared by manufacturing a liquid composition containing the antistatic components and softening the fabrics, and this composition can be used in conjunction with a suitable liquid detergent, by example, any of these products sold on the market to confer

  washed laundry with such detergent

  Thus, CISA or other suitable N- (higher aliphatic) isostearamide

  and bentonite (or other suitable softening clay)

  tissues) can be dispersed-emulsified

  suspended and / or partially dissolved in a

  suitable aqueous medium, with a minor proportion of hydrotrope, emulsifier,

This liquid preparation can be added to the liquid detergent beforehand and / or it can be added to the washing medium together with the liquid detergent, or it can be added to the compositions of the present invention or to

  washing water with such compositions in order to improve

  In addition, the flexibility and the antistatic properties of the laundry can be improved. By using the antistatic and fabric softening complementary composition, the present invention can be adapted to the use of any

  liquid detergent formulation. So, we leave it to the consumer

  the ability to judiciously determine the degree of antistatic and softening effects to be imparted to the laundry and it is possible to use more complimentary composition when using detergent compositions which are particularly potent detergents (or harsh ), requiring more flexibility and more antistat. Normally, in the liquid supplementation compositions described, the proportion of fabric softener and antistate combined present is 10 to 30%, but a proportion of 10 to 50% is possible, especially in the presence of a co-polymer. solvent such as ethanol. The ratio of antistat to bentonite is in the same range or ranges as previously indicated for the disclosed liquid detergent compositions containing both an antistat and a softener. Various advantages of the invention, some of which have already been mentioned, will be clearly illustrated in

  the working examples that follow. Isostearamide N-

  (primary aliphatic) antistatic does not react

  with bentonite or with anionic detergents,

  and therefore the compositions of the present invention

  are comparatively stable in storage and do not significantly lose their detergency, softening and antistatic properties during

  storage or before or during use. Contrary

  to cationic softener compositions

  fabrics and fabric softeners commonly used in

  such as quaternary ammonium salts,

  of the present invention do not deposit

  reaction products of such cationic materials and anionic detergents on the laundry being washed,

  so that the laundry is not so subject to

  during the washing operations when using the present invention. The detergent compositions of the invention provide whiter laundry and also produce less soil redeposition, while

  laundry washed with compositions containing a

  Anionic tergent and a quaternary ammonium salt (in antistatic and fabric softening proportions), tend to turn yellow, especially after repeated washings. The detergency is significantly better with the compositions of the present invention

  with compositions containing a quaternary ammonium salt

  ternary instead of isostearamide. Also, it avoids an influence on the foaming power of the anionic detergent, which is usually noticed in the presence of

  cationic compounds, such as quaternary ammonium salts

  and the reactions of these compounds quater-

  with fluorescent brighteners, and the decrease in

  the resultant brightening of the linen, when

  uses the antistats of the present invention. These inter

  undesirable actions of anionic and cationic materials are particularly serious and harmful when both

  anionic detergents and cationic compounds as

  Flexible and antistatic are present for relatively long periods in intimate contact, as is the case when they are in the same aqueous medium, for example in some anionic liquid detergents fabric softening. It's obvious that

  the present invention represents an im-

  advantageously have a viscosity within this range. More preferably, this range may be from 3000 to 5000 mPa.s, for example about 4000 mPa.s, at room temperature (25 C). Although the viscosities of the present compositions are considered to be comparatively stable, it has been established that

  When bentonite is removed from the formula

  of the invention, as in the fourth control, the detergent compositions are unsatisfactory as regards the softening power and the inhibition of static adhesion even in the presence of a proportion

  stearamide is removed, the static attachment of the washed laundry is still troublesome, despite the presence of 12% of bentonite. Thus, it can be seen that the combination of bentonite and N- (higher alkyl) isostearamide is important for successful laundry detergent compositions.

  Alternatively, the liquid antistatic softener can be added directly to the wash water in the washing machine, along with the liquid detergent. By any of these methods of use, any of the various commercially available synthetic anionic synthetic liquid organic detergent compositions can be improved in its antistatic and fabric softening effects.

  The anti-static softener may be that which is sufficient to give the washed laundry antistatic and discernible softening effects. For example, normally the charge in the rinsing water is 0.05 to 0.5%, preferably 0.1 to 0.3%, for example 0.2%. In a representative example of this embodiment of the invention, the laundry is washed as described in Example 1 with a detergent composition similar to that of this example, except that the bentonite and CISA are replaced by water (one may have added to the liquid a

  low proportion of gum or other thickener to

  adjust the viscosity, if desired, for example 0.1 to 1%

  of CMC, PVA (polyvinyl alcohol), PVP (polyvinyl-pyrrolidine)

  lidone) or other gum known for this use. After washing the laundry, which may be a normal load of mixed cotton and synthetic polymer fabrics, the antistatic softening composition of Example 2, which contains 14.1 parts of bentonite and 5.9 parts of CISA in 80 parts of deionized water is added to the rinse water at a concentration of 0.2% (130 grams per

  liters of rinsing water with a hardness of 100 ppm).

  The laundry is then dried, sometimes after several

  flexible than control linen which has not been subjected to

rinse procedure described.

  It goes without saying that the invention is not limited

  to the described embodiments and that it is likely

  various variants without departing from its scope.
