Abstract:
The present invention aims to provide a novel type I natural ceramide derivative having a structure more similar to that of a type I natural ceramide composed of sphingosine and an ω-acyloxy long-chain carboxylic acid; and a method for producing the same. The derivative is provided by reacting an ω-acyloxy long-chain fatty acid derivative with dihydrosphingosine or a salt thereof. The thus produced novel type I natural ceramide derivative, when combined with other ceramides, can significantly improve the compatibility of ceramides, which facilitates preparation of a composition containing ceramides, such as a moisturizer or a cosmetic, and also increases the storage stability of the composition.
