Abstract
The present invention relates to a personal care composition with a synthetic random copolymer having a net positive charge, a detersive surfactant; and an aqueous carrier.
Claims20
A personal care composition comprising:
- a) a synthetic random copolymer having a net positive charge comprising;
- i) a nonionic monomer unit of the following formula:
- where R is H or C1-4 alkyl;
- and R1 and R2 are independently selected from the group consisting of H, C1-4 alkyl, CH2OCH3, CH2OCH2CH(CH3)2, and phenyl, or together are C3-6cycloalkyl;
- and
- ii) a cationic monomer unit with 2 or more positive charges of the following formula:
- where k=1, each of v, v′, and v″ is independently an integer of from 1 to 6, w is zero or an integer of from 1 to 10, and X− is an anion;
- and
- iii) wherein the synthetic random copolymer comprises from about 0.5 to about 50%, by weight, of the cationic monomer;
- b) a detersive surfactant wherein said detersive surfactant comprises at least one anionic surfactant having an ethoxylate level and an anion level;
- wherein said ethoxylate level is from about 1 to about 10, and wherein said anion level is from about 1 to about 10;
- and
- c) an aqueous carrier.
