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.
Butylene glycol (1,3-butanediol, CAS 107-88-0) is an aliphatic diol used as a humectant and solvent. It serves as a co-monomer in polyester and polyurethane resins and as an intermediate in the manufacture of polyester plasticizers. Cosmetic and personal care formulations use it as a solvent and humectant.
Frequently Asked Questions
What is butylene glycol used for?
Butylene glycol (1,3-butanediol, CAS 107-88-0) is an aliphatic diol used as a humectant and solvent. Industrially it serves as a co-monomer in special polyester and polyurethane resins and as an intermediate for polyester plasticizers, and it is widely used in cosmetic and personal-care formulations as a solvent and humectant and as a carrier for flavor and fragrance compounds.
What is butylene glycol made out of?
The 1,3-butylene glycol grade (CAS 107-88-0, C4H10O2) is 1,3-butanediol, an aliphatic diol. It is manufactured industrially from acetaldehyde via aldol condensation and hydrogenation; bio-based routes from fermentation are also used for some grades.
What is the difference between butylene glycol and propylene glycol?
Both are diols used as humectants, solvents, and coupling agents, but they differ in carbon chain length. Butylene glycol is a four-carbon diol (1,3-butanediol, C4H10O2) while propylene glycol is a three-carbon diol (C3H8O2). The longer chain gives butylene glycol different solvency and feel characteristics that formulators select between by application.
What HS code applies to butylene glycol?
Butylene glycol is classified under HS heading 2905.39 (diols, other). Confirm the destination-country subheading with your customs broker before import.
How is bulk butylene glycol supplied?
RawSource supplies butylene glycol in drums, totes/IBCs, and bulk for resin, plasticizer, and personal-care customers. Specify whether you need an industrial or cosmetic grade and your target volume; a CoA and SDS accompany each shipment and pricing is quoted per order.
