Safety & Handling
Full SDS available on request
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Butyl oleate (CAS 142-77-8) is the n-butyl ester of oleic acid (butyl octadec-9-enoate). Esters of this type function as plasticizers and lubricants in polymer processing and as emollients in industrial and personal-care formulations.
Frequently Asked Questions
What is butyl oleate used for?
Butyl oleate (CAS 142-77-8) is the n-butyl ester of oleic acid. Esters of this type function as plasticizers and lubricants in polymer processing and as emollient esters in industrial and personal-care formulations.
Is oleate the same as oleic acid?
They are related but not identical. Oleic acid is the free fatty acid; an oleate is its ester or salt. Butyl oleate (butyl octadec-9-enoate) is specifically the n-butyl ester of oleic acid, formed by reacting oleic acid with n-butanol.
What is the CAS number and formula of butyl oleate?
Butyl oleate has CAS number 142-77-8 and molecular formula C22H42O2. Its systematic name is butyl octadec-9-enoate.
What HS code applies to butyl oleate?
Butyl oleate is classified under HS heading 2916.15 (oleic, linoleic or linolenic acids, their salts and esters). Confirm the destination-country subheading with your customs broker before import.
How is bulk butyl oleate supplied?
RawSource supplies butyl oleate in industrial bulk packaging for polymer-processing and formulation customers using it as a plasticizer, lubricant, or emollient ester. Specify your application and target volume; a CoA and SDS accompany each shipment and pricing is quoted per order.
