PEG/PPG-20/22 BUTYL ETHER DIMETHICONE

What Is PEG/PPG-20/22 BUTYL ETHER DIMETHICONE?

PEG/PPG-20/22 butyl ether dimethicone is a butyl-ether-modified PEG/PPG dimethicone copolymer. The butyl ether group enhances the emollient feel, while the PEG/PPG chains provide water-dispersibility. The PEG/PPG ratio (20/22) determines the HLB: higher PEG ratio = more water-soluble. Used as a skin conditioning agent for a silky, non-greasy finish.
