Abstract:
1. A block polymer suds stabilizer having the capacity to accommodate a zwitterionic character comprising: i) one or more cationic group-containing units; and ii) one or more additional building block units; provided that the block polymer has an average cationic charge density of about 5 or less units per 100 daltons molecular weight at a pH of from about 4 to about 12, said one or more additional building block units selected from the group consisting of one or more units having one or more hydroxyl groups, provided that said polymer has a Hydroxyl Group Density of about 0.5 or less, and one or more units having one or more hydrophobe groups selected from the group consisting of non-hydroxyl groups, non-cationic groups, non-anionic groups, non-carbonyl groups, and/or non-H-bonding groups; wherein said one or more cationic group-containing units comprises a cationic unit of the formula: wherein each of R wherein R wherein said block polymer has an average molecular weight of from about 35,000 to about 750,000 daltons.
