1,2-Hexanediol is a synthetic ingredient commonly used in cosmetics as a humectant and emollient. It helps retain moisture in the skin, keeping it soft and hydrated. Additionally, it provides a silky, non-greasy finish, making it ideal for lightweight skincare formulations. Its ability to attract and lock in moisture enhances the effectiveness of hydrating products.

This versatile ingredient also acts as a preservative booster, enhancing the efficacy of preservatives to maintain product safety and shelf life. Its antimicrobial properties further protect formulations from microbial growth. 1,2-Hexanediol doubles as a solvent, ensuring active ingredients are evenly distributed throughout the product for consistent performance.

Widely found in moisturizers, serums, cleansers, and sunscreens, 1,2-Hexanediol improves texture and extends shelf life. It is safe for use on most skin types, including sensitive skin, and supports clean beauty formulations by reducing the need for additional additives. Overall, its multifunctionality and gentle nature make it a valuable ingredient in modern cosmetics.
