Frequently Asked Questions
What is stearyl methicone?
Stearyl methicone (CAS 68554-54-1) is a stearyl (C18) alkyl-modified dimethicone, a wax-like silicone. In formulation it acts as an emollient and skin- and hair-conditioning agent, and as a structuring wax that adds body and water resistance to anhydrous and emulsion systems.
Is stearyl methicone the same as dimethicone?
No. Dimethicone is an unmodified polydimethylsiloxane fluid, whereas stearyl methicone is a dimethicone backbone modified with a long C18 stearyl alkyl chain. The alkyl modification makes it wax-like rather than fluid, giving it structurant and water-resistance functions dimethicone alone does not provide.
What is stearyl methicone used for?
It is used as an emollient that conditions skin and hair with a silicone-wax feel, as a structurant that adds body and viscosity to anhydrous sticks and balms, and to improve the wear and water repellency of films in emulsion and anhydrous systems.
How is stearyl methicone supplied in bulk?
We supply stearyl methicone to manufacturers in bulk industrial packaging. CAS is 68554-54-1 and it is classified under HS 3910.00 (silicones in primary forms). Request a quote with your required volume and packaging to receive current bulk pricing plus the CoA and SDS.
What HS code applies to stearyl methicone?
As a silicone in primary form, stearyl methicone is classified under HS 3910.00. Verify the exact destination subheading with your customs broker before import.
What is the REACH and TSCA regulatory status of Stearyl Methicone?
Stearyl Methicone (CAS 68554-54-1) is listed as Active on the U.S. EPA TSCA Inventory; its REACH registration status is not determined from the public ECHA registry.
