Cyclomethicone

Cyclomethicone (CAS 69430-24-6), also marketed under the broader class term cyclosiloxanes, is a blend of cyclic dimethylsiloxane oligomers.

Where is Cyclomethicone used?

• Personal care: delivery vehicle for active ingredients
• Skin creams, serums and hair care: improves spreadability and imparts a smooth, non-greasy skin feel
• Antiperspirants and deodorant sticks: solvent
• Coatings and release agents: disperses silicone actives uniformly across substrates before evaporating
• Textile finishing: carrier that deposits conditioning or softening agents onto fiber surfaces without heavy buildup
• It functions as a volatile carrier and conditioning agent, evaporating cleanly without residue.

Good to know: Individual cyclic fractions D4, D5 and D6 are available separately for applications requiring defined volatility profiles.
