Product Description
What Is D-Panthenol?
Provitamin B5 (D-Panthenol) is the alcohol form of Vitamin B5. Because of its healing, calming, and moisturizing qualities, it is frequently found in cosmetics and personal care products. D-Panthenol helps improve skin hydration, promotes wound healing, and enhances the appearance and texture of hair.
Preparation Method:
D-Panthenol is synthesized by reducing D-pantothenic acid using a reducing agent like sodium borohydride. This reaction converts the carboxyl group of pantothenic acid into a hydroxyl group, forming D-Panthenol. It can also be produced via fermentation processes, where microorganisms like Bacillus subtilis convert sugars into pantothenic acid, which is then reduced to D-Panthenol. D-Panthenol is commonly found in lotions, shampoos, conditioners, and skin creams for its ability to improve skin and hair health.
