Description

A liquid composition comprising a halogen bleaching agent and an amine compound, its use and a method for cleaning hard surfaces

Technical field

The present invention relates to a liquid composition comprising a halogen bleaching agent and an amine compound, to the use of the amine compound, and to a method for cleaning hard surfaces.

BACKGROUND OF THE INVENTION

Halogen bleaching agents, especially hypochlorites, are known to be one of the most effective hygiene agents, especially at low concentrations. They are available in commercial quantities at an affordable price. Halogen bleaching agents have beneficial hygienic effects against a variety of microbes including bacteria, fungi, yeasts and fungi.

Traditionally, the cleansing compositions are delivered to surfaces using a carrier such as a cloth or sponge onto which the composition is poured or dipped into a solution of the composition. This method of application results in a certain waste of product due to absorption on the fabric or sponge.

Recently, liquid products have been prepared in a package that is adapted for fine atomisation (aeorosol) or for product flow to facilitate delivery to the surface. A typical sprayer head comprises one relatively small opening into which the product is driven by a pump device operating with a pushbutton mechanism. The decisive factor is to determine whether the respective spray head will produce fog or stream including product properties, spray orifice geometry and spray pressure.

Known spray-related problems are the formation of airborne cap sticks that irritate the respiratory system in humans.

calf, either as a direct result of spraying mist or due to the impact of the current on a hard surface. Therefore, the instructions for use of some articles, especially those containing relatively high amounts of halogen bleaching agents, are recommended to the user not to spray the article directly onto the surface, but rather to spray it onto the fabric for subsequent application to the surface. Thus, the use of a substance or sponge reduces the suitability of using a spray.

It is therefore an object of the present invention to provide a sprayable composition comprising a halogen bleaching agent that does not have the above-mentioned problem of irritation of the user's respiratory system due to inhalation of airborne droplets.

Various solutions to this problem have been proposed in the art. For example, Japanese Patent 62/28600 proposes the use of specific solvents, WO 94/24259 proposes the use of surfactants in combination with a specific spray head package design, European Patent 594 314 proposes to regulate the viscosity of the selected surfactant to reduce the smell of bleach, including cases when droplets are formed in the air during delivery. Finally, WO 95/07957 proposes the use of thickeners for controlling the size of the irritating particles produced by the use of a nebulizer.

We have now found that the above object can be solved by making a sprayable liquid composition comprising a halogen bleaching agent and further comprising an effective amount of an organic or inorganic -NH ₂ compound. Without being bound by theory, it is believed that the -NH ₂ compound does not prevent the formation or inhalation of airborne droplets, but that it reduces or removes the irritation they cause.

Compositions comprising a halogen bleaching agent and an inorganic -NH ₂ compound have already been described in the art, but not in connection with a sprayable composition, see, for example, Japanese Patent 63-108099, European Patent 119,560,

Belgian patent 749,728, US patent 2,438,781, US patent

No. 749,672, British Patent 2,078,522, European Patent 362,178, and U.S. Patent 3,749,672.

SUMMARY OF THE INVENTION

In a first embodiment, the present invention comprises a composition comprising a halogen bleaching agent and an organic or inorganic -NH ₂ compound, wherein the composition is packaged in a nebulizer delivery device.

In a second embodiment, the present invention comprises a method of cleaning hard surfaces. According to this method, the surface to be cleaned is contacted with said composition by spraying said composition.

In a third embodiment, the present invention includes the use of an organic or inorganic -NH ₂ compound in a composition comprising a halogen bleaching agent to reduce respiratory tract irritation when sprayed.

The present invention provides compositions comprising the following ingredients.

Bleaching Agent: The present invention includes halogen bleaching agents which are oxidative bleaching agents and consequently give rise to a positive halogen ion. Typical of these types of bleaching agents are alkali metal and alkaline earth metal hypochlorites, hypobromites and iodates, although other bleaching agents which are based on a halide source organic compound such as chloroisocyanurate may also be used. A preferred bleaching agent is a compound of formula M (OX) _y wherein M is a member selected from the group consisting of sodium, potassium, magnesium, calcium and mixtures thereof, O is an oxygen atom, X is a member selected from the group consisting of chlorine, bromine, iodine, and mixtures thereof, and y is the number 1 or 2 according to the group M charge.

The process of the invention will effectively comprise hypochlorite or hypochlorite and hypobromite.

Preferred hypohalite bleaching agents included in the present invention are sodium hypochlorite, potassium hypochlorite, calcium hypochlorite, magnesium hypochlorite, sodium hypochlorite, potassium hypobromite, calcium hypobromite, magnesium hypochlorite, sodium iodate and potassium iodate, more preferred are sodium hypochlorite, potassium hypochlorite , calcium hypochlorite and magnesium hypochlorite, sodium hypochlorite being most preferred. A preferred organic compound bleaching agent is chloroisocyanurate, but any organic halogen compound that provides an active halogen atom is suitable for use in the present invention.

The compositions of the present invention preferably comprise a bleaching agent which is present in an amount of from 0.01 to 10, preferably from 0.01 to 2, more preferably from 0.1 to 2, most preferably from 0.5 to 2% by weight.

The -NH ₂ compound: The compositions of the invention further comprise an organic or inorganic -NH ₂ compound, or mixtures thereof, which are effective in reducing or eliminating irritation of the user's respiratory system caused by inhalation of airborne droplets of said composition. Examples of such compounds are sulfamic acid, sulfamide, p-toluenesulfamide, imidodisulfonamide, benzenesulfonamide, melamine, cyanamide, alkylsulfonamides, and mixtures thereof. At pH values of the present invention that are greater than 11, the above compounds may be deprotonated, that is, they may exist in the form of a salt, and thus due to the suitability, ease of synthesis or preparation, or all of the above compounds.

While any suitable cation is sufficient for the purposes of the present invention, sodium, potassium, lithium, magnesium, calcium and mixtures thereof are preferred.

The present invention comprises the -NH ₂ compounds in amounts such that the molar ratio of the hypochlorite bleaching agent to the odor control agent is from 10: 1 to 1:10, preferably from 5: 1 to 1: 2, more preferably from 3: 1 to 1 : 2.

Dispenser-type dispenser: According to the present invention, the compositions are packaged in a dispenser-type dispenser. A nebulizer type dispenser is understood to mean a dispenser capable of dispensing the composition it contains in the form of a stream of fine liquid droplets formed in air. These dispensers produce droplets of various sizes. Their smallest fraction is that which provokes irritation, the background discussed above.

Suitable types of dispensers to be used according to the present invention include aerosols as well as push button type foam dispensers sold, for example, by Specialty Packaging Products, Inc. or Continental Sprayers, Inc.

Such types of dispensers are described, for example, in U.S. Patent No. 4,701,311 to Dunnining et al. and U.S. Patent Nos. 4,646,973 and 4,538,745 to Focarracci. Particularly preferred for use in the present invention are dispenser type dispensers such as T8900 ^(R) and T8500 ^(S) , commercially available from Continental Spray International, or T8100 ^(R) , commercially available from Canyon, Northern Ireland. In this dispenser, the liquid composition is subdivided into fine liquid spheres which result in a spray directed to the surface to be treated. In such a dispenser type dispenser, the composition contained in the dispenser body is directed by the spray head with the energy supplied by the pump mechanism to the user as the user activates the pump mechanism. In particular, in the sprayer head of the dispenser, the composition is forcibly driven against an obstacle, such as a grid or a cone or the like, to provide a shock that helps atomize the liquid composition, i.e., helps to form liquid beads.

Supplementary Materials: The composition of the invention may optionally contain one or more detergent additive materials or other materials to assist or enhance the cleansing ability, treat the surface to be cleaned, or modify the aesthetics of the composition (e.g., perfumes, coloring agents, dyes, etc.) . The following are illustrative examples of these additional materials, which are not intended to be exclusive or limiting in scope.

Surfactant: Detergents contain from 0.1 to 95 wt. a surfactant selected from the group consisting of anionic, nonionic, ampholytic, and zwitterionic surfactants. The surfactants are preferably present in an amount of from 0.1 to 30% by weight of the composition.

Anionic surfactants can be broadly described as water-soluble salts, especially alkali metal salts, organic sulfonation reaction products having in their molecular structure an alkyl group having 8 to 22 carbon atoms and a group selected from the group consisting of sulfonic acid ester and Sulfuric acid ester groups (The alkyl moiety includes the alkyl portion of the higher acyl groups.). Important examples of anionic synthetic detergent agents that may form the surfactant component of the compositions of the present invention are sodium or potassium alkyl sulfates, especially those obtained by sulfating higher alcohols (C8-C18) produced by reducing tallow or coconut oil glycerides, sodium or potassium alkylbenzene sulfonates in which the alkyl group is a group having 9 to 15 carbon atoms (the alkyl group may have a straight or branched aliphatic chain), sodium alkylglyceryl ether sulfonates, especially esters of higher alcohols derived from tallow and basket oil, sodium monoglyceride sulfates and fatty acid sulfonates from coconut oil, sodium or potassium salt of sulfuric acid esters of the reaction product of one mole of a higher fatty alcohol (eg tallow or coconut alcohol) and from 1 to 10 moles of ethylenexoid,

Secondary alkyl sulfates may also be used by the formulator, either alone or together with other surfactants, and accordingly identifies and illustrates the differences between sulfated surfactants and otherwise conventional alkyl sulfate surfactants. Non-limiting examples of these ingredients are as follows.

Conventional primary alkyl sulfates, such as those mentioned above, are compounds of formula ROSO * M *, wherein R is typically a linear hydrocarbon group of 8 to 22 carbon atoms and M is a water-soluble cation. Also known are branched chain primary alkyl sulfate surfactants (i.e., branched chain PAS) of 8 to 20 carbon atoms, see, for example, European Patent Application 439,316 Smith et al, filed January 21, 1991.

Conventional secondary alkyl sulfate surfactants are those materials that have a sulfate group randomly distributed along the hydrocarbon backbone of the molecule. These materials are compounds of formula (CH ₂ CH ₂ (CH ₂ ) _m CH ₃ ) wherein m and n are at least 2, the sum of m + n is typically 9 to 17, and M is a water-soluble cation.

The selected secondary (2,3) alkyl sulfate surfactants to be used herein may contain compounds of formulas I ch ₃ (ch ₂ ) _χ (CHOSO ₃ M ⁺ ) ch ₃ (I) ·

And II ch ₃ (ch ₂ ) (choso ₃ 'm ⁺ ) ch ₂ ch ₃ (II) for 2-sulfate and 3-sulfate, respectively. Mixtures of 2- and 3-sulfate may be used herein. In formulas I and II, xa (y + 1) is at least 6 and can be numbers from 7 to 20, preferably from 10 to 16. M is a cation such as an alkali metal, ammonium, alkanoammonium, triethanolammonium and the like.

The above secondary alkyl sulfates are those compounds which are produced by adding H ₂ SO ₄ to olefins. Typical syntheses employing α-olefins and sulfuric acid are described in U.S. Patent No. 3,234,258 to Morris, issued February 8, 1966, or U.S. Patent No. 5,075,041 to Lutz, issued December 24, 1991. This synthesis is performed in solvents. which provide secondary (2,3) alkyl sulfates by cooling. Products are obtained which, when purified to remove unreacted materials, randomly sulphated materials, unsulphated by-products such as alcohols of 10 or more carbon atoms, secondary olefinic sulphonates and the like, are typically 90% or more by weight. pure mixtures of 2- and 3-sulfated materials (some sodium sulfate may be present), which are white, non-pale, seemingly crystalline solids. Something 2,3-disulfates may also be present, but they are usually present in an amount of not more than 5% by weight. from a mixture of secondary (2,3) alkyl monosulfates. These materials are available under the designation DAN, e.g., DAN 200 from Shell Oil Company.

Buffers: Buffers may be included in the compositions of the invention for various purposes. One such purpose is to adjust the pH of the cleaning solution so as to optimize the effectiveness of the hard surface cleaner relative to the respective type of dirt and / or stains. Buffers may be included to stabilize the additive components for extended life or to maintain compatibility between different aesthetic components, the hard surface cleaner of the present invention optionally containing buffers to adjust the pH to a preferred range above 11. Non-limiting examples of these suitable Buffers · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · ·

are potassium carbonate, sodium carbonate and sodium phosphate.

However, the formulator is not limited by these examples or combinations thereof.

Chelating Agents: The detergent compositions of the invention may also optionally contain one or more iron and / or manganese chelating agents. Examples of such compatible chelating agents are ethane-1-hydroxy-1,1-diphosphonic acid (EDHP) and dipicolinic acid.

Perfumes: Perfumes are an important ingredient, especially for performing a type of liquid composition. Perfumes are typically used in amounts of from 0 to 5% by weight. U.S. Pat. No. 4,246,129 to Karcher, issued Jan. 20, 1981 (incorporated herein by reference) discloses certain perfume materials that reduce the solubility of anionic surfactant and sulfated surfactants as an additional function.

Additional Supplements: In a preferred embodiment, the conventional adjunct ingredients used in the present invention may be selected from bleach stabilizers, pigments, stain removers, suds boosters, suds suppressors, anti-fading agents and / or anticorrosive agents, soil release agents, germicides, alkalinity sources, hydrotropic agents, antioxidants, soil removal / anti-fouling agents, polymeric dispersants, etc.

Amplifiers: As another optimal but preferred component, the present compositions comprise bleach enhancers. Bleach enhancers are those compounds which, in an alkaline pH environment, are capable of releasing a halogen ion subject to oxidation, reduction or other disproportionation that otherwise provides an activated halogen ion. When chlorine-based bleaching agents are used, typically bromine-containing enhancers are used. When bromine-based bleaching agents are used as the primary bleaching agent, they are used

bags with iodine atom. Preferred bleach enhancers are compounds of formula M (x) _y , wherein: a) M is a member selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, copper, zinc and mixtures thereof; a bromide, bromate, bromate, iodide, iodate group, and mixtures thereof, wherein y is 1 or 2.

Without wishing to be bound by theory, it is believed that enhancers have the effect, as in the case of hypochlorite-based bleaching agents, of converting a hypochlorite bleaching agent into more reactive and / or more stable particles, such as bromate, thereby achieving the full usefulness of the bleaching agent prepared. The bleach enhancers of the present invention may be added as a precursor, which may itself be a bleach enhancer, for example, iodine ion is a suitable bleach enhancer of the present invention, but the hypohalite / iodide ratio may be adjusted by preparing an in situ iodate formation agent. , a preferred bleach enhancer. Amplifiers thus produced by oxidation / reduction or other disproportionation, for example iodate, can be added directly.

The bleach enhancers of the present invention are compounds of formula MX wherein M is a member selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, copper and zinc, wherein X is a halogen atom. Preferred bleach enhancers are the sodium and potassium salts of bromine and iodine, more preferably sodium and potassium bromide and iodide.

The present invention includes bleach enhancers that are present in an amount such that the molar ratio of bleach to bleach enhancer is from 1: 0.1 to 1: 2, preferably from 1: 0.2 to 1: 1.
