Description

  • This invention relates to the detergent utilization of certain copolymeric ingredients in a compatibilizing functionality in conjunction with performance additives. The copolymeric ingredient is prepared from an ethylenically unsaturated carboxylic acid and an ethylenically unsaturated dicarboxylic acid. Preferred monomers are acrylic and methacrylic acids on one hand and maleic and citraconic acids on the other hand. The copolymeric agent was found to be especially suitable for enhancing the compatibility of detergent additives which are known to be sensitive to various conditions inclusive of prolonged storage, temperature, alkalinity, and/or laundry conditions. In more detail, the copolymeric compatibilizing agent is capable of procuring, in contradistinction to their art-established functionality, unexpected transfer properties in relation to specific detergent additives. These transfer properties go against the prevailing opinion according to which comparable copolymeric adjuvants serve as deposition inhibitors, and consequently diminish the physical contact between detergent ingredients and e.g. the fiber.
  • The use of low levels of (co)polymeric additives for detergent application has been known for a long time and has found application in commercial detergent products. European Patent Application 0009171, BASF AG, published April 2, 1980 relates to the incorporation of polymaleic acid as a builder ingredient and/or as an incrustation inhibitor in detergents. European Patent Application 0025551, BASF AG, published March 25, 1981 discloses the utilization of (meth)acryIic · acid-maleic acid copolymeric ingredients as incrustation inhibitors in detergent compositions. The copolymer comprises a large majority of the (meth)acrylic acid monomer FR-A-2388045, The Procter & Gamble Company, published November 17, 1978, pertains to detergent compositions containing surface-active agents, builders and a binary system based on not more than 4% of a polyphosphonate and not more than 4% of a polymeric ingredient which can be represented by the copolymers obtained from the polymerization of (meth)-acrylic acid and maleic anhydride.
  • German Patent Application DOS 19 59 272, Procter & Gamble European Technical Center, published July 23, 1970, relates to solid oxygen-bleach detergent compositions containing a copolymeric ingredient based on vinyl methylether and maleic anydride. The copolymeric ingredient is claimed to provide effective active oxygen regulation.
  • It has now been discovered that the particular copolymeric ingredient of the invention herein can be used beneficially with a view to secure very desirable performance benefits upon use in combination with particular detergent additives with the proviso that the copolymeric ingredient is preferably used in excess levels in relation to a given performance additive.
  • It is an object of this invention to formulate detergent compositions having desirable performance characteristics containing specific detergent additives.
  • It is a further object of this invention to formulate laundry products capable of providing superior overall performance in presence of specific additives.
    • Brief description of the invention
  • It has now been discovered that markedly improved detergent compositions can be formulated containing a conventional detergent matrix in combination with detergent performance additives and a copolymeric ingredient. The performance additives are present in an amount from 0.002% to 5% by weight. The copolymeric ingredient is prepared from an ethylenically unsaturated carboxylic acid monomer having not more than five carbon atoms and from an ethylenically unsaturated dicarboxylic acid monomer having not more than six carbon atoms, whereby these monomers are copolymerized in a molar proportion of 1:4 to 4:1. The weight ratio of the copolymeric ingredient to the performance additives is from 500:1 to 1:5. Performance additives for use in combination with the copolymeric ingredients are selected from water-soluble porphine photoactivators such as mixtures of sulfonated metal phthalocyanines; and renewable polyamine or amine oxide soil release agents.

  • It goes without saying that the detergent matrix of the compositions of this invention can also contain other major components according to the particular needs and/or the physical state of the invention. In this respect, the compositions herein can be solid, pasty or liquid. Major amounts of pH regulants, inert fillers like sodium sulfate, water and/or organic solvents like hydrocarbons and/or lower alcohols can be applied as is well-known in the art. The detergent matrix can also contain major levels of bleaching agents, for example, oxygen bleach agents such as perborate, percarbonate, perpyrophosphate, persilicate or, more in general, all oxygen-bleach agents which are known to be suitable for use in detergent compositions in the established levels.

The term performance additive as used herein is meant to express that the specific ingredient is added either to cure a deficiency of the general detergent matrix and/or to provide special laundry and cleaning benefits.
  • A class of performance additives that can be utilized beneficially in combination with the copolymeric agent is represented by a photoactivator, also frequently termed a photosensitizer. The photoactivator is a porphine of a mono-, di-, tri-, or tetraaza porphine solubilized with anionic, nonionic, and/or cationic substituent groups and metal free or metallated with Zn(II), Ca(II), Cd(II), Mg(II), Sc(III), AI(III), or Sn(IV). Preferred metal-ions forthe photoactivator are zinc and aluminum. The photoactivator is frequently used in low levels, e.g., in the level from about 20 ppm to 2000 ppm. In solid detergent compositions, the photoactivator is generally used in combination with a carrier material such as polyphosphates, sulfates, a.s.o. Generally, the level of such photoactivator particles (containing a carrier material) represents from 0.1 % to 1% of the detergent composition. The photoactivator is believed to exhibit its activity in the direct environment of the fiber possibly in combination with perborate. The copolymeric ingredient favors this transfer of photoactivator to the fiber in presence of the other components in the laundry liquor at the applicable temperatures, e.g., laundry temperatures in the range from up to about 60°C or up to the boil.
  • As an example, a water-soluble photoactivator used in the specified levels can be represented by the porphine activators of European Patent Application 0003149. The weight ratio of copolymer to photoactivator performance additive is frequently in the range from 500:1 to 7:1.
  • The copolymeric ingredient was also found to be effective in combination with additive levels of renewable soil release agents as described in EP-A-0042187 and EP-A-0042188. The copolymeric ingredient enhances and contributes to a more quantitative deposition of the renewable soil release agent, specifically the polyamines oxidized or not and/or the oxidized monoamines.
