The primary function of cyclopentasiloxane is to work as an emolient. It can also give products a silky feel, which allows them to glide smoothly and deliver any active ingredients to the body evenly.
Manufacturers also use it as a solvent to help deliver active ingredients in a product to the skin or hair. However, unlike other silicones, cyclopentasiloxane is volatile which means that it quickly evaporates and dries when applied to the skin. It helps make formulations feel smooth and silky for a smooth and easy application. It allows products to spread evenly over the skin so that all areas of the skin receive key ingredients from a product.
