Cyclopentasiloxane

Cyclopentasiloxane is a high-purity, volatile cyclic dimethyl silicone fluid, commonly known as D5. It appears as a clear, colorless, odorless liquid with low viscosity and low surface tension. This versatile silicone fluid offers excellent spreading and rub-out properties, imparting a silky, non-greasy feel to the skin and hair without leaving any oily residue or buildup. As a volatile carrier, it is highly compatible with a wide range of cosmetic ingredients and evaporates completely after application. Our Cyclopentasiloxane is widely used as an emollient, solvent, conditioning agent, and pigment dispersant in personal care formulations. It delivers consistent quality and reliable performance for your most demanding cosmetic and personal care applications.
