Hexanediol (commonly 1,2-hexanediol) is a multifunctional ingredient used in skincare as a humectant, solvent, and antimicrobial agent that enhances preservative efficacy and product stability. It is widely employed in formulations to improve texture and reduce reliance on traditional preservatives.

Allergic contact dermatitis | Rare | Sensitization reported in isolated cases; generally considered low-allergenicity. |
Dryness with high concentrations | Rare | Possible at elevated levels acting as a solvent. |
