Use:Cyclo-2345 D5/D6 Cyclomethicone is a volatile polydimethylcyclosiloxane (Cyclomethicone) that is composed of approximately 75% Cyclopentasiloxane (CAS #541-02-6) and approximately 25%of Dodecamethylcyclohexasiloxane (CAS# 540-97-630 ). The fluid 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. ….see also Cosmetic Grade Silicones

Cyclomethicone Fluids are exempt from Federal VOC regulation-s including California (CARB) and OTV VOC regulations. They do not contribute to ozone-depletion and global warming, and are being widely accepted as replacements for Non-VOC petroleum-based solvents. As carrying agents, Cyclo-2244 and Cyclo-2245 have comparable evaporation rates to naptha solvents, odorless mineral spirits (OMS) as well as some of the isoparaffinic solvents. Cyclo-2345 can be an alternative if a slower evaporation rate is desirable. Cyclomethicones are compatible with most substates, including metals and plastics.
