Science
Mechanism of Action
As a skin conditioning agent, this compound is believed to enhance skin hydration by forming hydrogen bonds with water molecules, thereby diminishing transepidermal water loss and reinforcing the skin's natural barrier function. Its polymeric structure also enables it to act as a film former, providing a protective layer.

The Formula
Formulation
Stability
This ingredient is reported to be stable and, as a polyfluorinated polymer, generally exhibits high thermal stability. Its solubility is ambiguously described as ranging from insoluble to soluble in water. However, a related phosphate derivative can be made water-soluble through neutralization, suggesting potential for formulation flexibility despite initial challenges.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined that there is insufficient data to definitively assess the safety of this ingredient and other fluorinated polyethers in cosmetic applications. This substance is a member of the per- and polyfluoroalkyl substances (PFAS) class, which are of significant concern due to their environmental persistence, potential for bioaccumulation, and documented links to adverse health effects, including immunotoxicity, reproductive and developmental issues, cancer, and cardiovascular, liver, and thyroid disruptions in humans and animals. While a structurally similar compound showed no mortalities or signs of general toxicity and no evidence of skin sensitization in a guinea pig dermal toxicity test, these findings are not considered conclusive for this specific ingredient. The FDA also notes a lack of publicly available toxicokinetic and toxicity information for some cosmetic PFAS, complicating comprehensive safety evaluations.
