1,2-Hexanediol

1,2-Hexanediol is a six-carbon aliphatic diol that serves as a multifunctional ingredient, primarily valued for its ability to enhance the efficacy of traditional preservatives at concentrations of 0.5-2%. Unlike simple glycols, its specific molecular structure provides superior antimicrobial boosting properties while simultaneously acting as a lightweight solvent that improves the skin feel of formulations without greasiness. Formulators favor it because it allows for reduced concentrations of traditional preservatives, supports clean beauty claims, and provides additional moisturizing benefits through its humectant properties.
