Definitions

  • the present invention relates to wash-active substances which contain water-soluble block copolymers. Furthermore, the present invention relates to a method for producing such wash-active substances and the use of special block copolymers in wash-active substances.
  • Wash-active preparations are usually used to clean soiled textiles, in particular soiled clothing.
  • textiles of all kinds in particular, however, such textiles as are used for the production of clothing, usually contain a large number of different fabrics, which, moreover, have been provided with different colors by a wide variety of dyeing processes.
  • the cleaning of textiles by means of washing-active substances should expediently remove dirt from the textiles without, however, significantly changing the original appearance of the textiles in terms of color and structure. While this task for monochrome textiles, which ideally consist of only one material, is relatively easy to solve, problems arise with regard to the cleaning of multicolored textiles or a mixture of textiles of different colors.
  • the cleaning of textiles or textile mixtures which have light colors and dark colors, for example white and blue or white and black, is particularly problematic.
  • DE-A 2 232 353 describes a detergent and cleaning agent mixture with an improved inhibitory effect on dye transfer.
  • a proportion of a water-soluble polymer component based on polyvinylpyrrolidone to a detergent and cleaning agent mixture.
  • a copolymer of polyvinyl pyrrolidone with acrylonitrile or maleic anhydride is described as advantageous.
  • the copolymers mentioned have no block structure.
  • DE-A 28 14 287 also describes a detergent containing discoloration-inhibiting additives. To prevent discoloration occurring during the washing process, it is proposed to add a water-soluble or dispersible homopolymer or copolymer of N-vinylimidazole to a washing and cleaning agent. However, the polymers described also have no block structure.

It is possible in the context of the present invention that the transition between two blocks runs continuously, that is to say that between two blocks there is a zone which has a statistical or regular sequence of the monomers constituting the blocks, but it is also contemplated within the scope of the present invention that the transition between two blocks is essentially discontinuous.
  • a “substantially discontinuous transition” understood a transition zone that has a significantly shorter length than at least one of the blocks separated by the transition zone. It is possible for a block to be based on only one type of monomer. However, it is also contemplated that a block be constructed from two or more monomers. In a preferred embodiment of the present invention, the chain length of such a transition zone is less than 1/10, preferably less than 1/20, of the block length of at least one of the blocks separated by the transition zone.
  • a “different monomer composition” is further understood to mean that the monomers constituting the respective block differ in at least one feature, for example in their interlinking, in their conformation or constitution. If, as already described above, If a block is constructed from more than one type of monomer, different blocks of the block copolymer may differ in the present context, for example, also by different concentrations of the monomers constituting a block, preferably block copolymers which have at least two blocks are used in the context of the present invention whose monomer composition differs at least through the constitution of the monomers.

  • bleaches containing active chlorine for example sodium hypochlorite, littaiim hypochlorite, sodium or potassium dichloroisocyanurate or trichloroisocyanuric acid, or else mixtures of alkali persulfates and alkali chlorides, which combine when used to form hypochlorite, can react with the detergents according to the invention become. This combination can take place during the manufacture of the detergents or also immediately before or during use. To avoid Losses can also be encased or granulated by the active chlorine compounds with inorganic or organic coating substances.
  • the detergents can also contain optical brighteners, in particular derivatives of diaminostilbenedisulfonic acid or its alkali metal salts. Suitable are for example salts of 4,4-bis (-2 "-anilino-4" -morpholino-l, 3,5-triazinyl-6 "-amino) - stilbene-2,2'-disulfonic acid or compounds of similar structure, which carry a diethanolamino group, a methylamino group or a ß-memoxyethylamino group instead of the morpholino group
  • brighteners for polyamide fibers are those of the diarylpyrazoline type, for example 1 - (- p-sulfonamidophenyl) -3- (p-chlorophenyl) - ⁇ 2 -pyrazoline and compounds of the same structure which carry a carboxymethyl or acetylamino group instead of the sulfonamido group It is also possible to use substituted aminocoumarins
  • Suitable graying inhibitors are, in particular, carboxymethyl cellulose, methyl cellulose, furthermore water-soluble polyesters and polyamides from polyvalent carboxylic acids and glycols or diamines, which have free carboxyl groups, betaine groups or sulfobetaine groups capable of salt formation, and polymers or copolymers of vinyl alcohol, vinyl pyrrolid, which are colloidally water-soluble in water and acrylonitrile.
  • the agents can also contain enzymes from the class of proteases, lipases and amylases or mixtures thereof. Enzymes obtained from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus are particularly suitable. Neutral salts, in particular sodium sulfate, and bioeides, such as halogenated diphenylmethanes, salicylanilides, carbanilides and phenols, are suitable as further constituents.
  • Liquid agents can also contain hydrotropic substances and solvents, such as alkali salts of benzene, toluene or xylene sulfonic acid, urea, glycerin, polyglycerin, di- or triglycol, polyethylene glycol, ethanol, i-propanol and ether alcohols.
  • solvents such as alkali salts of benzene, toluene or xylene sulfonic acid, urea, glycerin, polyglycerin, di- or triglycol, polyethylene glycol, ethanol, i-propanol and ether alcohols.
  • foam inhibitors such as saturated fatty acids and their alkali soaps with 20 to 24 carbon atoms, trialkylmelamines, hydrocarbons and silicones, may also be present.
  • the quantitative composition of the detergents according to the invention can vary within wide limits, preferably within the following (in percent by weight):
  • 0.1-10% preferably 0.2-5% polymer according to the invention 0.5-30%, preferably 1-20% soap and / or sulfate or sulfonate surfactant, 0.5-30%, preferably 1st - 20% nonionic surfactant, 0 - 60%, preferably 5 - 50% builders,
  • oxygen-releasing bleaching agents in particular Na perborate and its combination with bleach activators and stabilizers, 0 - 3%, preferably 0.5 - 2% of anti-graying agents
  • Substances 0-1%, optical brighteners, dyes and fragrances, and antimicrobial substances, 0-3%, preferably 0.2-2%, of foam inhibitors.
  • the present invention also relates to a method for producing a detergent substance according to one of claims 1 to 6, characterized in that at least 0.01 to 50% by weight of a block copolymer A with a molecular weight of more than 1000, which can be prepared by a process comprising the following steps (i) and (ii):
  • R 1 to R 3 each independently of one another are hydrogen, methyl or a radical-stabilizing and / or sterically demanding group selected from an unsubstituted or substituted, linear or branched-chain alkyl having two or more carbon atoms,
  • the present invention also relates to the use of a block copolymer A with a molecular weight of more than 1000, which can be prepared by means of a process described above comprising steps (i) and (ii), for the production of detergent preparations.
  • the poly (N-vinylpyrrolidone-b-styrene) prepared according to Example 1 was used as the dye transfer inhibitor.
  • the addition of 1% of one of the polymers to be used according to the invention prevents the dye transfer to cotton and polyester / cotton in a very pronounced manner.
  • the polymer has a more color transfer inhibiting effect at the same concentration than commonly known color transfer inhibiting polymers.

Abstract
