An oral care composition comprising:

• an orally acceptable carrier;
• an amphoteric surfactant having a structure of formula (I):
• wherein L is a substituted or unsubstituted (C2-C4) alkylene,
• n is an integer from 1 to 10,
• Ra and Rb are independently C1-C4 alkyl,
• R is substituted or unsubstituted C1-C20 alkyl, and

• an orally acceptable cationic antibacterial agent;
• and
• a copolymer of i) an allyl phosphate compound;
• and ii) one or more α, β-ethylenically unsaturated co-monomers, at least one of which is other than an allyl-functional co-monomer,
• wherein the allyl phosphate compound has the formula (A):
• [CH2═CH—CH2—O(R1O)a(R2O)b]xP(O)(OM)3-x (A)
• wherein
• R1 is a substituted or unsubstituted (C2-C4) alkylene moiety;
• R2 is a substituted or unsubstituted (C2-C4) alkylene moiety;
• M is identical or different, hydrogen, alkali metal, ammonium, protonated alkyl amine, protonated alkanolamine, or protonated basic amino acid;
• X is 1 or 2;
• a is from 1 to 20;
