1, 2-Hexanediol Description

1,2-hexanediol is a synthetic preservative, solvent and moisture-binding agent used in skin care and cosmetics. As a humectant, 1,2-hexanediol works to draw moisture to skin, helping to promote hydration.

Its primary action as a preservative is against bacteria, not molds or fungi, so it would never be used as the sole preservative in a water-based formula. Because of its low molecular weight chemical structure, it is highly water soluble and can also help improve the efficacy of other preservatives.

The ingredient 1,2-hexanediol also has texture-enhancing and wetting properties when used in higher amounts, helping to create smooth-flowing gels and serums.

1,2-hexanediol has been reviewed by the Expert Panel for Cosmetic Ingredient Safety. The Expert Panel concluded that 1,2-hexanediol is safe as used in cosmetics and personal care products. It is considered non-sensitizing.

Outside of skin care, this ingredient is used in hair care.
