1,3-Butanediol

1,3-Butanediol (CAS 107-88-0), also known as 1,3-Butylene glycol, is a short-chain diol used across personal care, polymer, and coatings industries. It functions primarily as a humectant, plasticizer, and reactive intermediate.

In personal care, it conditions and retains moisture in skin creams, serums, and hair products. It is often preferred over propylene glycol for its lighter skin feel and excellent safety profile in topical applications.

Polymer manufacturers use it as a chain extender and cross-linking agent in polyurethane synthesis. This directly influences the hardness and flexibility of the final elastomer produced for industrial use.

Coatings and adhesive formulators incorporate it to improve film flexibility and substrate adhesion. It is effective in both solvent-borne and waterborne systems for various commercial coating projects.

It also functions as a plasticizer in specialty sealants and elastomers where controlled softness and elongation are required. This versatility makes it a staple component in modern chemical manufacturing.

1,3-Butanediol is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Bulk tanker options are also available for high-volume buyers requiring consistent large-scale deliveries.

Cosmetic-grade and technical-grade specifications are the most commonly traded. Cosmetic-grade material meets purity requirements suitable for leave-on and rinse-off personal care formulations.

Technical-grade supply serves polymer and industrial coating applications where cosmetic-grade purity is not required. This ensures cost-effective sourcing for heavy industrial and manufacturing sectors.
