D-Panthenol USP
D-Panthenol USP, also known as Provitamin B5, is the dextrorotatory isomer of panthenol and is biologically active. It is a water-soluble, viscous, clear liquid with a slightly sweet odor and is widely used in pharmaceutical, cosmetic, personal care, and nutraceutical applications. D-Panthenol is the alcohol analog of pantothenic acid (Vitamin B5) and is converted into Vitamin B5 in the skin and body, where it plays a vital role in cellular metabolism and tissue repair. Its moisturizing, anti-inflammatory, and healing properties make it highly valuable across industries.
