What is 1,2-octanediol?
1,2-Octanediol (CAS 1117-86-8), also sold as caprylyl glycol, is a multifunctional diol.
Where is 1,2-octanediol used?
- Cosmetic and skincare: antimicrobial booster enhancing preservative systems
- Moisturizers, serums and hair care: skin-conditioning and moisture-retention properties
- Pharmaceutical topical preparations: co-solvent or humectant in creams and ointments
- Coatings and adhesives: reactive diol component in crosslinking systems
- It functions as a preservation booster, humectant and emollient.
Good to know: Often replaces or reduces the load of traditional preservatives, allowing formulators to meet challenge test requirements with lower preservative concentrations.
Commercial specifications
- High-purity grades typically exceed 98% assay
- Packaging from small drums to bulk quantities
