D-Panthenol

D-Panthenol (CAS: 81-13-0)

D-Panthenol, the biologically active dextrorotatory isomer of panthenol, is a provitamin of pantothenic acid (Vitamin B5). It deeply hydrates skin and hair by converting to Vitamin B5, enhancing barrier function, accelerating wound healing, and reducing inflammation. Highly soluble in water and alcohols, it is ideal for serums, creams, and hair care formulations. Its superior penetration and stability (pH <5) make it preferred for high-efficacy products targeting dryness, irritation, or damage. Studies confirm its role in stimulating fibroblast proliferation and UV protection synergy with zinc oxide.
