Patent ID: 8541357

Claim:
A cleaning composition comprising an amphoteric polymer and a surfactant system, wherein the amphoteric polymer is formed from a plurality of structure units together defining a total mass, such that: from 1% to 99% by mass of the plurality of structure units, based on the total mass, are cationic-group structure units having formula (IB) or (IIB): where: R 0 is —H or —CH 3 ; R 1 is —CH 2 —, —CH 2 CH 2 —, or a direct bond; R 2 , R 3 , and R 4 each are independently selected from C 1-20 organic groups; R 5 and R 6 each are independently selected from —H and C 1-20 organic groups; each Y 1 is independently selected from C 2-20 alkylene groups; n is from 1 to 300 and represents an average addition number of moles of oxyalkylene groups (—Y 1 —O—); and X − is a counteranion; and from 1% to 99% by mass of the plurality of structure units, based on the total mass of the plurality of structure units, are carboxyl structure units each derived from a carboxyl group-containing monomer; and wherein the surfactant system comprises at least one C 10 -C 16 alkyl benzene sulfonate surfactant.
