Cleaning compositions with amphoteric polycarboxylate polymers

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:
• R0is —H or —CH3;
• R1is —CH2—, —CH2CH2—, or a direct bond;
• R2, R3, and R4 each are independently selected from C1-20 organic groups;
• R5 and R6 each are independently selected from —H and C1-20 organic groups;
• each Y1 is independently selected from C2-20 alkylene groups;
• n is from 1 to 300 and represents an average addition number of moles of oxyalkylene groups (—Y1—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-C16 alkyl benzene sulfonate surfactant.
