Octamethyl Cyslotetrasiloxane D4 CAS:556-67-2 Purity 95%-99%
BS- D4 Cyclomethicone is a volatile polydimethylcyclosiloxane that is composed mainly of octamethylcyclotetrasiloxane
(CAS#556-67-2). The product is clear, tasteless, essentially odorless, non-greasy and non-stinging.
Due to their volatility (varying rates of evaporation), low surface tensions
(high spreadability), and non-greasy feel, Cyclomethicones are used as base fluids, carrying agents and wetting agents in a wide range of personal care products. Cosmetic applications include: room sprays, body sprays, antiperspirants, skin creams, skin lotions, suntan lotions, bath oils, hair care products etc.
