Abstract
Personal care compositions having excellent shear, shelf and use stability as well as excellent formulation aesthetics (such as skin feel, residue, moisturizing, emolliency, rub-in, absorption and adsorption characteristics, and the like) are made using inverse emulsion polymers having improved electrolyte tolerance and efficiency. The personal care compositions comprise (A) a topically acceptable liquid phase, and (B) at least one electrolyte tolerant inverse emulsion polymer comprising the reaction product of: (1) at least one complex associative monomer having ethylenic unsaturation in an end group, a hydrophilic midsection, and a hydrophobic moiety; (2) at least one pH sensitive monomer having ethylenic unsaturation and at least one carboxylic or sulfonic acid group; (3) an optional copolymerizable non-ionic monomer having ethylenic unsaturation; and (4) at least one crosslinking monomer.
