CAS:556-67-2, 541-02-6
INCI:Cyclotetrasiloxane, cyclopentasiloxane
Composition:Cyclotetrasiloxane, cyclopentasiloxane
Purity Grade:No purity grade applicable
Appearance:Clear to slightly hazy liquid, odorless
Solubility:Very low water solubility (20 micrograms/L), soluble in alcohol, mixable in oils
Preservation:Preservative-free
Storage:Store in a closed container at a dry place at room temperature
Country of Origin:China
Raw Material Source:Dimethyldichlorosilane and water
Manufacture: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).
Animal Testing:Not animal tested
GMO:GMO-free (does not contain plant-derived components)
Vegan:Does not contain animal-derived components
HS Code:3208100000
Description
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.
Benefits
- 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
Use
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.
