POLYPERFLUOROETHOXYMETHOXY DIFLUOROMETHYL ETHER.

Avoid CAS 161075-02-1 / SOLVENT

Polyperfluoroethoxymethoxy Difluoromethyl Ether functions as a film former, establishing a delicate, invisible barrier on the skin. This layer is engineered to repel water, aid in sustaining the skin's natural moisture, and provide prolonged defense against dehydration. It also contributes to a refined product texture, delivering a silky sensation without any greasy residue.

Science

Mechanism of Action

This ingredient operates by forming a soft, imperceptible film on the skin's surface. This fluorinated film is understood to provide water repellency, which supports the skin's intrinsic moisture balance and offers long-lasting protection against transepidermal water loss. Moreover, it enhances the tactile quality of cosmetic products, yielding a smooth, non-oily finish.
