Expert Verdict

Phthalate backbone raises CMR concerns. Residual monomer (diallyl phthalate) is classified as a skin sensitizer and suspected reproductive toxicant. Even if the polymer itself is inert, EU/California regulatory trend is toward elimination of all phthalate-derived ingredients. Extremely limited cosmetic use โ€” not recommended for cosmetic formulation.
