Polysilicone-38 is a siloxane polymer that is made is several steps. First, Cyclotetrasiloxane is polymerized with Bis-Hydrogen Disiloxane, reacted to produce Bis-Hydrogen Dimethicone, which is reacted with PEG-48 diallyl ether and allyl glycidyl ether. Finally, the siloxane polymer is reacted with is capped with and Diisopropanolamine
