Usage: D-Panthenol is the provitamin of D-Pantothenic acid (Vitamin B5), which plays a key role in the human intermediary metabolism. Deficiency of Vitamin B5 can result in many dermatological disorders. D-Panthenol is applied in pharmaceutical industry and almost all types of cosmetic preparations. It cares hair, skin and nails. 1. In skin D-panthenol is a deep penetrative humectant. It can stimulate the growth of epithelium and has an antiphlogistic effect to promote wound healing 2. In hair D-panthenol can keep moisture longly and prevents hair damage. It can also thicken hair and improve luster and sheen 3. In nail care D-panthenol can improve hydration and impart flexibility Stability and Storage: D-Panthenol is stable to air and light but unstable to heat. Stored at below 25 degrees Centigrade in tightly sealed, original containers, it has a shelf life of 36 months. In weakly acidic, aqueous solutions, D-Panthenol is considerably more stable than the salts of pantothenic acid. It is unstable in strong acids and bases. Package: 20kgs/Carton (10kgs/Pail) |
