Science

Mechanism of Action

PENTAERYTHRITYL TETRA C5-10 ACID ESTERS operates by creating a film on the skin's surface, effectively locking in moisture and reinforcing the skin's natural barrier. This action minimizes water evaporation, leading to increased hydration, a softer texture, and a refined, silky feel. Beyond its direct skin benefits, it also functions as a binder and a non-aqueous viscosity regulator in cosmetic formulations.
