Description

technical field

[0001] The invention belongs to the technical field of chemical synthesis and relates to a preparation method of D-panthenol. Background technique

[0002] Panthenol also known as provitamin B 5 , can be divided into 3 forms of DL-type, D-type and L-type, of which only the D-type has biological activity, and the L-type has no biological activity; D-panthenol is an optically active stereoisomer of ubiquinol body.

[0003] D-panthenol is the equivalent of D-pantothenic acid, which is widely used in medicine, food, feed and cosmetic industries. In the food industry, it is used as a nutritional supplement and fortifier to promote the metabolism of human protein, fat, and sugar, maintain skin and mucous membranes, improve hair luster, improve immunity, and prevent the occurrence of diseases; in the cosmetics industry, on the skin The care function of the hair is manifested as a deeply penetrating moisturizer, which stimulates the growth of epithelial cells, pro...
