Overview of Cyclopentasiloxane

Cyclopentasiloxane is a volatile silicone fluid widely used in cosmetics and personal care products for its lightweight, silky, and fast-spreading feel. It helps products glide smoothly on skin and hair without leaving a greasy residue. Because it evaporates quickly after application, it delivers a dry, smooth finish, making it highly preferred in premium formulations.

Its CAS number is 541-02-6, and it is usually supplied as a clear, colourless liquid. Cyclopentasiloxane is often used with ingredients such as Dimethicone, Phenyl Trimethicone, Cyclohexasiloxane, Caprylic/Capric Triglyceride, and Isododecane to enhance sensory performance and product stability.
