POLYPERFLUOROETHOXYMETHOXY DIFLUOROETHYL PEG DIISOSTEARATE.

Avoid / SKIN CONDITIONING

Polyperfluoroethoxymethoxy Difluoroethyl PEG Diisostearate is a polyfluorinated polymer primarily recognized for its film-forming and skin conditioning properties. As a member of the per- and polyfluoroalkyl substances (PFAS) class, it can also influence product consistency and impart a smooth, shiny appearance to skin and hair.

Summary

Film former Skin conditioning agent Skin protectant Emollient Slip modifier Viscosity increasing agent (nonaqueous)

Science

Mechanism of Action

This ingredient functions by creating a protective film on the skin's surface, contributing to its conditioning and helping maintain its state. As a polyfluorinated polymer and a PFAS, it can enhance cosmetic product texture, providing slip and aiding in viscosity control, while also smoothing skin and hair for a potentially glossy finish.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that there is insufficient data to ascertain the safety of Polyperfluoroethoxymethoxy Difluoroethyl PEG Diisostearate. This ingredient belongs to the class of per- and polyfluoroalkyl substances (PFAS), which are synthetic chemicals known to be persistent, accumulating in living organisms and the environment, raising significant health concerns. The FDA has identified substantial data gaps for PFAS in cosmetic products, lacking information on use levels, dermal/oral absorption, mechanistic details, and dermal toxicity. General class-wide concerns for PFAS include potential links to cancer, allergies, immunotoxicity, developmental and reproductive toxicity, and thyroid disruption.
