Personal care composition for a keratin substrate comprising conditioning, color protecting and styling polymer

A conditioning, color protecting and/or styling terpolymer for a keratin substrate obtained by polymerizing:

• i. about 50 wt. % to 99 wt. % of acrylamidopropyl trimethylammonium chloride (APTAC), a cationic monomer;
• ii. about 0.1 wt. % to 30 wt. % of acrylamido methylpropyl sulfonate (AMPS), an anionic second monomer;
• and
• iii. about 0.1 wt. % to 20 wt. % methaacryloylaminopropyl lauryl-dimethyl ammonium chloride (MAPLDMAC), a hydrophobically modified cationic monomer;
• wherein said terpolymer has a cationic degree of substitution (Cat-DS) of greater than about 0.001 units, and wherein the cationic charge density is in the range of about 1 meq/g to about 6 meq/g.
