About this ingredient

A volatile cyclic silicone fluid that evaporates quickly to leave a smooth, non-greasy finish on skin and hair. It functions as a spreading agent and solvent in cosmetic formulations, improving product spreadability, texture, and sensory appeal. Commonly used in primers, foundations, and hair care products for its lightweight feel and fast-drying properties.
