BRB SG 116 - Cyclopentasiloxane & Dimethicone Cross Polymer

Cyclopentasiloxane & Dimethicone Crosspolymer – Silky Smooth Base for Serums & Primers

This silicone blend features Cyclopentasiloxane (D5), a volatile silicone that evaporates after application, and Dimethicone Crosspolymer, a gel-forming elastomer. Together, they create a lightweight, cushiony feel perfect for oil-free serums, blur creams, mattifying primers, and shine-free hair products. They enhance spreadability, reduce tackiness, and act as excellent carriers for actives, pigments, and oils. The resulting textures feel powdery, soft, and airbrushed on the skin.
