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, i.e. they also prevent inorganic, insoluble salts from being deposited on the fabric.
  • 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 with regard to the overall effect as a builder and the inhibition ability 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-detergent detergents largely prevent incrustation.
  • copolymers which can be obtained by copolymerization of maleic anhydride with (meth) acrylic acid and subsequent saponification, have a K value of 10 to 40 in the unsaponified state, determined according to Fikentscher in methyl ethyl ketone at 25 ° C., and in the saponified state - based on the weight of the polymers - containing 40 to 90% (meth) acrylic acid and 60 to 10% maleic acid as monomer units, or their alkali or ammonium salts as phosphate substitutes with incrustation-inhibiting action in detergents in an amount - based on dry substance - from 0.5 to 10% by weight.
  • the copolymers show 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 have K values from 10 to 40, which are determined in accordance with Fikentscher, Cellulosechemie 13, page 58 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 contained 5 g / l, 8 g / l and 11 g / l test detergent B.
  • the detergent solution contained 5 g / l detergent C.
  • the detergent solution contains 8 g / I test detergent B.
