Process of making D-panthenyl triacetate

摘要

A process of making D-panthenyl triacetate which includes reacting D-panthenol with acetic anhydride in the presence of the catalyst polymer bound dimethylaminopyridine to form an exothermic mixture. The so-produced acetic acid, and the catalyst are removed from the exothermic mixture which is then neutralized with sodium hydroxide. Sodium acetate in the form of a solid is removed by filtration. The D-panthenyl triacetate is useful in cosmetic compositions.
