Science
Mechanism of Action
This ingredient operates as a highly effective skin conditioning agent, delivering a multi-faceted approach to skin enhancement. As a silicone, it forms a vapor-permeable protective film on the skin's surface, which helps to retain moisture, ensuring sustained hydration and a soothing effect. This film also contributes to excellent spreadability, making product application smoother. Furthermore, it significantly improves skin feel, providing a distinct silicone softness, silkiness, and a cushioned sensation. In hair care, it serves as a plasticizer for fixative resins and facilitates panthenol penetration into the hair shaft.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly assessed dimethicone polymers, including POTASSIUM DIMETHICONE PEG-7 PHOSPHATE, concluding their safety for use in cosmetic formulations. This determination, initially made in 2003 and subsequently reaffirmed, is based on the ingredient's large molecular weight, which significantly limits skin absorption, especially at typical usage concentrations. Further reinforcing its safety profile, the U.S. Food and Drug Administration (FDA) has recognized this ingredient as safe for certain food applications.
