Description
D-Panthenol (CAS 81-13-0) is the biologically active dextrorotatory form of pantothenic acid (vitamin B5), commercially known under trade names such as Bepanthen, Bepantol, Bepanthene, and Cozyme. It carries no assigned E-code and is identified under EC number 201-327-3 with molecular formula C9H19NO4.
In personal care formulations, D-Panthenol functions as a humectant by binding water within the hair cortex and skin layers, improving elasticity and reducing breakage in conditioning products. In pharmaceutical topical preparations, it converts enzymatically to pantothenic acid within skin tissue, supporting epithelial repair. It also serves as a crosslinker and heat stabilizer in select polymer and coating applications.
D-Panthenol is available in cosmetic and pharmaceutical grades, compliant with Ph.Eur. monograph standards and REACH registration requirements. It is supplied as a viscous liquid in drums and IBCs. Procurement professionals should confirm grade specification against intended application, as cosmetic and pharma grades carry distinct purity thresholds.
