Hydroxystearyl alcohol

Hydroxystearyl alcohol (CAS 2726-73-0), also known commercially as 1,12-Octadecanediol, is a long-chain diol derived from hydroxystearic acid. It functions as an emulsifier, rheology modifier, and conditioning agent across personal care and industrial formulations.

Buyers source it primarily for its dual hydroxyl functionality, which enables performance in both polar and non-polar systems. In skin and body care, it acts as an emollient and co-emulsifier in creams, lotions, and lip products.

This chemical contributes to texture and moisture retention without heaviness. Lubricant formulators incorporate it into metalworking fluids and grease compositions where its diol structure improves film formation and load-bearing properties.

In coatings and adhesives, it serves as a reactive intermediate or additive to adjust viscosity and improve substrate adhesion. Sealant and elastomer manufacturers use it as a chain extender or plasticizer component in polyurethane-based systems.

Hydroxystearyl alcohol is supplied as a white to off-white waxy solid, typically in flake or pastille form. It is available in cosmetic-grade and technical-grade specifications to meet the requirements of personal care and industrial buyers.

The material is manufactured to high quality standards to ensure consistency across batches. Packing is commonly offered in 25 kg bags or fiber drums to facilitate easy handling and storage for large-scale manufacturing operations.
