Definitions

  • phosphate substitutes must be used.
  • nitrilotriacetic acid, polycarboxylic acids, such as gluconic acid, citric acid, and then polymeric acids, such as poly (meth) acrylic acid, maleic acid / vinyl ether copolymers, and more recently also polymaleic acids have become known.
  • polycarboxylic acids such as gluconic acid, citric acid
  • polymeric acids such as poly (meth) acrylic acid, maleic acid / vinyl ether copolymers, and more recently also polymaleic acids
  • the phosphates are not only excellent builders with complexing power, they also act as secondary detergents, ie they also prevent the deposit of inorganic, insoluble salts on the P tissue. This deposit is called incrustation, and it has been shown that none of the phosphate substitutes used hitherto are capable of replacing phosphates on an equivalent basis in terms of their overall action as a builder and in terms of their inhibition capacity against incrustation. Additives had to be used to deal with the problem of incrustation.
  • the aim of the present invention was to find substances which, in the smallest possible amounts, added in low-phosphate-free or low-phosphate detergents largely prevent incrustation.
  • copolymers containing 40 to 90% by weight of (meth) acrylic acid and 60 to 10% by weight of maleic acid as monomer units. Also suitable are their alkali metal, preferably sodium and ammonium salts. '
  • the copolymers Compared to pure polyacrylic acid and pure polymaleic acid, the copolymers have an abruptly improved inhibition capacity against incrustations in textile washing processes with phosphate-free and low-phosphate detergents.
  • the copolymers are obtained in a manner known per se by copolymerization of maleic anhydride with (meth) acrylic acid in the proportions given (calculated as maleic acid) and subsequent saponification. Amounts are preferably chosen such that 45 to 85% by weight of (meth) acrylic acid and 55 to 15% by weight of maleic acid are present in the copolymer.
  • the polymerization is carried out by free radical initiation in solution, suspension or as precipitation polymerization.
  • the polymerization temperatures are about 50 to 200, preferably 100 to 150 ° C.
  • Suitable initiators are the customary radical-forming compounds, such as dialkyl peroxides, alkyl hydroperoxides, peresters, diacyl peroxides and azo compounds, such as azoisobutyronitrile.
  • the copolymers obtained in the unsaponified state preferably have K values of 10 to 40, which according to Fikentscher, Cellulosechemie 13, page 58 can be determined in methyl ethyl ketone at 25 ° C.
  • copolymers are added to detergents, based on dry substance, in amounts of 0.5 to 10, preferably 2 to 6,% by weight.
  • the copolymers are in the form of the corresponding alkali salts; they can also be used directly as the alkali, preferably sodium or ammonium salt.
  • the three test detergents therefore have a greatly reduced phosphate content compared to conventional detergents (approx. 45 to 55% phosphate).
  • the detergent solution contains 5 g / l detergent A.
  • the detergent solution contained 5 g / l, 8 g / l and 11 g / l test detergent B.
  • the detergent solution contained 5 g / l of detergent C.
  • the detergent solution contains 8 g / l test detergent B.
