Request SDS →Butyl stearate (CAS 123-95-5) is the n-butyl ester of stearic acid (butyl octadecanoate). It is used as a plasticizer for cellulose acetate butyrate, cellulose nitrate, ethyl cellulose, and polystyrene; as a lubricant in PVC extrusion and molding; and as an emollient in creams, lotions, and lipsticks. It also serves as a softening and spreading agent.
Frequently Asked Questions
What is butyl stearate used for?
Butyl stearate (CAS 123-95-5) is the n-butyl ester of stearic acid. It is used as a plasticizer for cellulose acetate butyrate, cellulose nitrate, ethyl cellulose, and polystyrene; as an internal lubricant in PVC extrusion and molding; and as an emollient and spreading agent in creams, lotions, and lipsticks.
What is normal butyl stearate?
'Normal' (n-) butyl stearate refers to the straight-chain n-butyl ester of stearic acid, butyl octadecanoate (CAS 123-95-5, C22H44O2). The 'n-' distinguishes it from branched butyl isomers and specifies the linear butyl group on the ester.
What is butyl stearate made from?
Butyl stearate is produced by esterifying stearic acid with n-butanol, yielding butyl octadecanoate (C22H44O2). It is a fatty-acid ester used as a plasticizer, lubricant, and emollient.
What HS code applies to butyl stearate?
Butyl stearate is classified under HS heading 2915.70 (palmitic acid, stearic acid, their salts and esters). Confirm the destination-country subheading with your customs broker before import.
How is bulk butyl stearate supplied?
RawSource supplies butyl stearate in industrial bulk packaging for plastics, PVC-processing, and personal-care formulators. Specify your application and target volume; a CoA and SDS accompany each shipment and pricing is quoted per order.
