Abstract

A detergent or cleaning composition containing a copolymeric polycarboxylic acid or salt thereof which is a terpolymer of (a) a monoethylenically unsaturated C.sub.3-8 carboxylic acid, (b) a 2-alkyl or aryl allylsulfonic acid, and (c) a carbohydrate. The invention also relates to builder compositions containing the above terpolymer.

Independent Claims | See all claims (16)

  1. 1. In a detergent or cleaning composition, the improvement wherein the composition contains an incrustation inhibiting quantity in the amount from about 0.5 to about 30% by weight of the composition of at least one biodegradable terpolymer consisting of the monomer units of (a) from about 40 to about 60% by weight of at least one of a monoethylenically unsaturated C.sub.3-8 monocarboxylic acid and a salt thereof, (b) from about 10 to about 30% by weight of at least one of a 2-alkyl or aryl allylsulfonic acid and a salt thereof, and (c) from about 15 to about 40% by weight of a carbohydrate and from about 10 to about 65% by weight of a water-containing zeolite, a crystalline layer silicate, or a mixture thereof.
  2. 14. A builder composition comprising from about 1 to about 30% by weight of at least one biodegradable terpolymer consisting of the monomer units of (a) from about 40 to about 60% by weight of at least one of a monoethylenically unsaturated C.sub.3-8 mono carboxylic acid and a salt thereof, (b) from about 10 to about 30% by weight of at least one of a 2-alkyl or aryl allylsulfonic acid and a salt thereof, and (c) from about 15 to about 40% by weight of a carbohydrate, and from about 50 to about 70% by weight of a zeolite, a crystalline layer silicate, or a mixture thereof.
