BRB CM 50 Cyclopentasiloxane (D5)

BRB CM 50 is a silicone-based cosmetic ingredient based on Cyclopentasiloxane (D5), a lightweight and volatile silicone fluid. It is a clear, odorless liquid that evaporates quickly after application, leaving the skin and hair with a smooth, silky, and non-greasy feel.

Its excellent spreadability and elegant sensory properties make it widely used in premium skincare, haircare, makeup, sunscreen, and personal care formulations.
