Cosmetic grade 1,2-Hexanediol (CAS 6920-22-5) is an advanced synthetic material widely used in modern skincare formulations for its powerful moisturizing and antibacterial effects. When included at concentrations above 5%, it acts as a natural preservative, making it ideal for preservative-free cosmetic systems. This ingredient not only extends product shelf life but also enhances skin feel, delivering a smoother and more pleasant experience.
