Science
Mechanism of Action
This ingredient, a polyfluorinated polymer and PEG derivative, exerts its conditioning effects by forming a protective or lubricating film on hair and skin surfaces. Its molecular structure also allows it to facilitate the dissolution of other compounds and influence the overall viscosity and texture of a product.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed data insufficient to assess the safety of this ingredient, categorizing it within polyfluorinated polymers with significant data gaps. The U.S. Food and Drug Administration (FDA) reported in December 2025 that safety could not be determined for most Per- and Polyfluoroalkyl Substances (PFAS), including this ingredient, due to a severe lack of toxicological data, use levels, absorption information, and mechanistic understanding. While no federal bans exist, several U.S. states are implementing or discussing restrictions on PFAS in cosmetics. The Environmental Working Group (EWG) classifies this ingredient as 'RESTRICTED' due to potential concerns including skin and respiratory irritation, particularly noted in household cleaning products.
