Dimethicone and Methicone are silicone based polymers. The only difference between these two polymers is that the repeating unit of Dimethicone contains two methyl groups, while the repeating unit of Methicone contains one methyl group. Other Dimethicone and Methicone based polymers that may be used in cosmetics include Amino Bispropyl Dimethicone, Aminopropyl Dimethicone, Amodimethicone, Amodimethicone Hydroxystearate, Behenoxy Dimethicone, C30-45 Alkyl Dimethicone, C24-28 Alkyl Dimethicone, C30-45 Alkyl Methicone, Cetearyl Methicone, Cetyl Dimethicone, Dimethoxysilyl Ethylenediaminopropyl Dimethicone, Hexyl Methicone, Hydroxypropyldimethicone, Stearamidopropyl Dimethicone, Stearoxy Dimethicone, Stearyl Methicone, Stearyl Dimethicone and Vinyl Dimethicone.
