1,2-Decanediol

1,2-Decanediol (CAS 1119-86-4), also known as Decylene Glycol, is a multifunctional diol used across personal care, pharmaceutical, and cleaning formulations. It functions simultaneously as a humectant and emollient booster.

This versatile chemical acts as a broad-spectrum antimicrobial agent, allowing formulators to reduce or replace conventional preservatives. In rinse-off and leave-on cosmetics, it provides skin-conditioning benefits while extending efficacy.

Moisturizers, serums, and cleansers benefit from its ability to enhance the preservative system. Pharmaceutical topical formulations use it as a co-solvent and mild preservative aid in various creams and ointments.

It is particularly useful where low-irritation alternatives to parabens are required for sensitive applications. Home care and industrial cleaning products incorporate it to enhance surfactant performance and biocidal activity.

The compound contributes activity against bacteria and fungi on treated surfaces. It is also used as an emulsifier aid in oil-in-water systems, improving droplet stability in both rinse-off personal care and household concentrates.

1,2-Decanediol is supplied as a white to off-white solid or low-melting waxy material, depending on temperature. Cosmetic and pharmaceutical grades are the most commercially prevalent, with purity typically at 98% or higher.

The material is available in drum and IBC quantities suited to industrial formulation volumes. It meets rigorous industry requirements for stability and performance across a wide range of chemical manufacturing sectors.
