Panthenol

Panthenol (pantothenol) is the alcohol analog of pantothenic acid (vitamin B₅), and is thus a provitamin of B₅. In organisms it is quickly oxidized to pantothenate [pantothenic acid]. Panthenol is a highly viscous transparent liquid at room temperature, but salts of pantothenic acid (for example sodium pantothenate) are powders (typically white). It is soluble in water, alcohol, propylene glycol, ether and chloroform, and slightly soluble in glycerin.
