Glycerin,1,2-Hexanediol

GLY

8/10

Concern level

High concern

A cosmetic blend of two small polyols: glycerin (a classic humectant) and 1,2-hexanediol (a humectant/solvent and preservative booster). In formulations it helps attract and retain water, improve slip, and support product preservation. Glycerin is widely used as a barrier-supporting hydrator, while 1,2-hexanediol is commonly used at low levels for humectancy and antimicrobial support.

incompatible with: No major incompatibilities are expected with most skincare actives., May sting when layered immediately after strong acids, retinoids, benzoyl peroxide, or over-exfoliated skin due to barrier disruption, even though the ingredient itself is not a strong active.

As a blend, it is not a known major sensitizer, but any cosmetic ingredient can trigger individual intolerance.
