Not reviewed
Sensitization risk High

This copolymer has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. However, phthalic anhydride, a critical monomer in its composition, is a known potent sensitizer and irritant for both skin and the respiratory tract. Phthalic anhydride also undergoes exothermic hydrolysis with water.
