: 100% active cyclic silicone polymer blend consisting of siloxane D4 (cyclotetrasiloxane) and siloxane D5 (cyclopentasiloxane). Cyclic silicones are low-molecular weight silicones and are not viscous but very fluid and often used as solvents. Linear silicones (e.g. dimethicone) are large high-molecular polymers that are viscous and more oil-like. Clear to slightly hazy liquid, odorless. Very low water solubility (20 micrograms/L), soluble in alcohol, mixable in oils. CAS
: 556-67-2, 541-02-6 INCI Name
: Cyclotetrasiloxane, cyclopentasiloxane
- Rapidly evaporates without cooling the skin. Leaves the skin dry, smooth and silky
- Ideal carrier for makeup, other color cosmetic skin creams, deodorants and stick products without the oily feel
- Provides excellent stability and aesthetics
: Typical use level 1-10% (up to 50% possible), add to oil phase of formulas but do not heat over 50°C (125°F). Can also be mixed into emulsions after the temperature drops to 50°C (125°F). For external use only. Applications
: Color cosmetics, creams, deodorants, sticks, hair care products.
Country of Origin
Raw material source
: Dimethyldichlorosilane and water
: Cyclomethicone is made from dimethyldichlorosilane which is produced by powdered silicon (silicone dioxide) and methyl chloride. Dimethyldichlorosilane is then hydrolyzed to give a hydrolysate mixture of polysiloxanes. In a polymerization reaction with water the polysiloxanes are then polymerized to a cyclic polymer (cyclomethicone) consisting of either 4 siloxane units (cyclotetrasiloxane) or 5 siloxane units (cyclopentasiloxane).
