<unk>  is the alcohol analog of pantothenic acid (vitamin B5), and is thus the provitamin of B5. In organisms it is quickly oxidized to pantothenate.<unk>  is a highly viscous transparent liquid at room temperature, but salts of pantothenic acid (for example sodium pantothenate) are powders (typically white). It is well soluble in water, alcohol and propylene glycol, soluble in ether and chloroform, and slightly soluble in glycerin.<unk>  comes in two enantiomers, D and L. Only D-panthenol (dexpanthenol) is biologically active, however both forms have moisturizing properties. For cosmetic use,<unk>  comes either in D form, or as a racemic mixture of D and L (DL-panthenol).
Pantothenol's expanded chemical formula is: HO-CH2-C(CH3)2-CH(OH)-CONH-CH2CH2CH2-OH.
