Frequently Asked Questions

What is dimethicone crosspolymer used for?

Dimethicone crosspolymer is a crosslinked silicone (dimethicone) polymer used in personal-care formulations as a thickening and gelling agent for the oil phase, a sensory modifier that imparts a soft, powdery feel, and a carrier network for oil-soluble actives.

What is the difference between dimethicone crosspolymer and dimethicone?

Dimethicone is a linear silicone fluid, while dimethicone crosspolymer is a crosslinked (networked) version of that polymer. The crosslinking is what lets it gel and thicken oil and silicone phases rather than flow as a fluid.

What is dimethicone crosspolymer, chemically?

It is a crosslinked polydimethylsiloxane network in the silicone fluids and oils family, referenced under CAS 300-00-5 in supplied documentation. It functions as a gellant, thickener, and sensory modifier in oil-phase formulations.

What HS code is dimethicone crosspolymer classified under?

It ships under HS 3910.00 (silicones in primary forms). Verify the destination tariff line and documentation with your customs broker before shipment.

How is bulk dimethicone crosspolymer packaged?

RawSource supplies dimethicone crosspolymer to personal-care formulators in drums and totes, with CoA and SDS per lot. Pricing is quote-based on grade, volume, and packaging; request a current bulk quote with your target quantity.
