PERFLUOROPROPYLENE/VINYLIDENE DIFLUORIDE COPOLYMER.

Avoid CAS 9011-17-0 / FILM FORMING

PERFLUOROPROPYLENE/VINYLIDENE DIFLUORIDE COPOLYMER is a synthetic polymer designed to form a continuous, flexible film on the skin. While it can enhance product texture and longevity, its classification as a Per- and Polyfluoralkyl Substance (PFAS) raises significant concerns regarding environmental persistence and potential systemic health impacts.

Summary

Not reviewed
Pregnancy
Caution
Sensitization risk High

This ingredient is identified as a Per- and Polyfluoralkyl Substance (PFAS), a class of compounds of significant concern due to their environmental persistence and bioaccumulation. Its safety has not been reviewed by the Cosmetic Ingredient Review (CIR). Concerns include potential for enhanced skin absorption, moderate endocrine disruption, and moderate non-reproductive organ system toxicity. PFAS have been epidemiologically linked to liver effects, immunotoxicity, developmental and reproductive issues, various cancers, cardiovascular disruption, and thyroid dysfunction in both human and animal studies. The Environmental Working Group (EWG) designates it 'Unacceptable' for its Verified products due to these substantial health and environmental concerns.
