Hexanediol

TL;DR. This ingredient primarily functions as a humectant, solvent, and preservative booster, helping formulas hold water while improving the performance of antimicrobial systems. It can also support a lighter skin feel in emulsions and gels.

What does Hexanediol do in a cosmetic formula?

Is Hexanediol clean?

From a clean-beauty perspective, it is generally well tolerated and widely accepted by many retailer standards, but it can draw scrutiny because it is often synthetically made and used as part of preservation strategy. Sensitivity is uncommon, though higher levels may feel warming or sting on compromised skin.

Is Hexanediol sustainable?

This material is commonly derived from petrochemical feedstocks, although bio-based routes exist. It is expected to be readily biodegradable and is not known for major persistence or bioaccumulation concerns.

Is Hexanediol COSMOS-approved?

It is not broadly aligned with COSMOS organic or natural standards unless a specific approved raw-material route and use context is documented by the supplier. From a Green Chemistry view, its small structure and biodegradability are positives, while conventional fossil sourcing is the main compromise.

How does Hexanediol work chemically?

The molecule is a small six-carbon diol with two alcohol groups, giving it both water affinity and modest interaction with oily phases. Typical use levels are about 0.5 to 2%, sometimes up to 3%, and it is generally stable across common cosmetic pH ranges while pairing well with organic acids, glycols, and conventional preservatives.
