Cyclomethicone

120 ml =~109 g
A volatile silicone oil used in hair and skincare products to impart skin conditioning, emolliency, shine and/or silkiness; to reduce the greasy feel of tanning oils; promotes easy spreadability, and leaves a soft, silky smooth feel to the skin. Evaporates quickly leaving little residue on the skin.

Cyclomethicone is a blend of decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane with a low viscosity, a relatively high volatility and a cyclic structure.

It is non-polar and insoluble in water but completely miscible in lower alcohols, aliphatics, aromatics and halogenated solvents and can be used in antiperspirants and skin care formulations.


Description: 100?tive 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

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.
