Decamethylcyclopentasiloxane (D5) is a volatile cyclic silicone widely used in cosmetics and personal care products for its unique lightweight, fast-evaporating properties that leave no residue on skin or hair. It functions as a carrier and spreading agent for active ingredients, improves the application and glide of foundations, antiperspirants, and hair serums, and provides a dry, non-greasy after-feel. D5 is commonly used as a co-solvent in deodorant and antiperspirant formulations. AB Enterprises supplies cosmetic grade Decamethylcyclopentasiloxane for skin care, hair care, and color cosmetic manufacturers.
