Overview
1,2-Hexanediol (CAS 6920-22-5 ), also known as 1,2-Dihydroxyhexane, is a short-chain diol used primarily as a multifunctional ingredient in personal care and industrial formulations.
It combines humectant, emulsifying, and antimicrobial-boosting properties in a single raw material, reducing the need for additional additives. Formulators source it as a cost-effective alternative to traditional glycols.
In personal care, it functions as a humectant and skin-conditioning agent in moisturizers, serums, and sunscreens, while also enhancing the efficacy of preservation systems.
Coating and adhesive manufacturers incorporate it as a reactive diol for crosslinking resins, improving film flexibility and adhesion to substrates in various industrial settings.
In home care and industrial cleaning products, it aids in solubilizing fragrance oils and active ingredients within aqueous systems. It also supports emulsion stability in rinse-off and leave-on formulations.
1,2-Hexanediol is supplied as a clear, low-viscosity liquid. Cosmetic-grade material meeting standard purity requirements is the most commonly traded specification for global distribution.
Technical-grade options are available for coatings and industrial applications. Bulk supply is standard in drums and IBCs, with smaller packaging available for laboratory and development quantities.
