What It Does

Cyclopentasiloxane is a volatile cyclic silicone fluid that provides a unique dry, silky feel without leaving residue on skin or hair. It evaporates quickly after application, making it ideal as a carrier for other ingredients and creating lightweight formulations. Formulators choose D5 for its excellent spreading properties, ability to reduce the greasy feel of heavy oils, and its role in creating smooth, non-tacky textures in serums, primers, and hair products.
