Frequently Asked Questions
What is methyl trimethicone?
Methyl trimethicone (CAS 63148-57-2) is a low-viscosity, volatile silicone fluid used in personal-care formulations as a lightweight, non-greasy emollient, a fast-spreading carrier, and a skin- and hair-conditioning agent. RawSource supplies it in bulk to cosmetic and personal-care formulators.
What is methyl trimethicone used for?
It is used as a volatile emollient and spreading agent that improves sensory feel, and as a conditioning and shine agent in hair-care products. Because it is volatile, it evaporates after application rather than leaving a heavy residue.
What is the difference between methyl trimethicone and dimethicone?
Methyl trimethicone is a low-molecular-weight, volatile silicone that flashes off after spreading, while dimethicone is a non-volatile silicone polymer that remains as a film. Formulators choose methyl trimethicone for a light, fast-spreading carrier and dimethicone for lasting slip and barrier feel.
What CAS number and family does methyl trimethicone fall under?
CAS 63148-57-2, family Silicone Fluids & Oils, formula C10H30O3Si4. It is also known by the chemical name methyltris(trimethylsiloxy)silane.
How is methyl trimethicone shipped?
It is associated with UN 1993 (flammable liquid, n.o.s. – methyltris(trimethylsiloxy)silane) for transport; confirm the applicable shipping classification on the SDS. RawSource supplies it in bulk with a CoA and SDS per shipment; request a bulk quote with your target volume.
