CompendialRequirements: D-Panthenol meets allrequirements of the USP, the FCC the BP and EP. when testedaccording to those compendia.

Stabilityand Storage: D-Panthenol is fairly stable toair and light. It is hygroscopic and sensitive to heat; heatingover 70??? may cause race mission. The shelf life is 36 months fromthe date of production when stored in the unopened originalcontainer at room temperature(below 25???). The effective “best usebefore” details stated on the label. In aqueous solutions,D-Panthenol is markedly more stable than the salts of pantothenicacid, in particular at a PH of 3 to 6. It can adjust the metabolismof protein, carbohydrate and fat, preserve the mucous on the skinsurface and shine of the hair (or feather) and preventdiseases.

Usage:D-Panthenol is applied in almost all types of cosmeticpreparations. It cares hair, skin and nails. D-Panthenol is theprovitamin of D-Pantothenic acid (Vitamin B5), which plays a keyrole in the human intermediary metabolism. Deficiency of Vitamin B5can result in many dermatological disorders.

Role in the skin: 1, deep penetratingmoisturizer 2, stimulates epithelisation (fibroblast proliferationand normal keratinization) 3, wound healing effect 4,anti-inflammatory effect

Role in the hair: 1, long lasting moisturizer2, prevents hair damage 3, thickens hair 4, improves luster andsheen

Role in nail care: 1, improves hydration 2,imparts flexibility
