Description
(±)-Pantolactone (CAS 79-50-5), also known as DL-Pantolactone, DL-Pantoyl lactone, or (RS)-Pantolactone, is the racemic lactone form of pantolactone, a cyclic ester structurally related to pantothenic acid (vitamin B5). It carries no assigned E-code and is classified under HS code 29322090.
In cosmetic formulations, pantolactone functions as a humectant by binding water within the stratum corneum, improving skin hydration without occlusion. In pharmaceutical synthesis, it serves as a chiral building block and stabilizing intermediate in the production of pantothenic acid derivatives. Its antioxidant activity also supports shelf-life extension in nutrient-containing formulations.
(±)-Pantolactone is available as a solid suitable for pharmaceutical and cosmetic-grade applications, with supply conforming to REACH registration requirements for the European market. Procurement teams should confirm grade specifications against Ph.Eur. or FCC standards depending on the intended application. Standard packaging formats vary by supplier volume requirements.
