Abstract:
1. A polymer suds/foam stabilizer consisting essentially of: A. at least one cationic monomeric unit A, capable of having a cationic charge at a pH in the range of from 4 to 12, having a Formula I: wherein R R wherein R 3 is selected from the group consisting of and a is an integer from 0 to 16; b is an integer from 2 to 10; c is an integer from 2 to 10; d is an integer from 1 to 100; R R R R B. at least one monomeric unit B selected from the group consisting of: wherein n is an integer from 1 to 50; and C. at least one monomeric unit C selected from the group consisting of: and wherein R wherein said polymer has an average cationic charge density of 0.75 to 2.25 units per 100 daltons molecular weight at a pH of 4 to 12 and a molecular weight of 10,000 to 100,000 daltons, wherein the molar ratio of said monomeric unit A:monomeric unit B:monomeric unit C is 1 to 9:1 to 9:1 to 6 respectively, and wherein the polymer is a suds/foam stabilizer.
