摘要:
The present invention provides a ceramide dispersion which includes (1) ceramide-containing particles which contains a ceramide, which are dispersed in an aqueous phase as an oil-phase component, and which have a volume average particle diameter from 1 nm to 100 nm; and (2) a fatty acid component which is at least one of a fatty acid having a melting temperature not higher than 30° C. or a fatty acid salt; the amount of nonionic surfactant being 0 or not more than 0.1 times the total mass of the ceramide; the amount of an ionic surfactant other than the fatty acid component being 0 or less than 0.05 times the total mass of the ceramide; and the pH being from 6 to 8.
