Panthenol is an odourless, slightly bitter, highly viscous, transparent and colourless liquid at room temperature,[5] but salts of pantothenic acid (for example sodium pantothenate) are powders (typically white). It is easily soluble in water and alcohol, moderately soluble in diethyl ether, soluble in chloroform (1:100),[5] in propylene glycol, and slightly soluble in glycerin.
