Patent ID: 8642052

Claim:
A ceramide dispersion comprising: (1) ceramide-containing particles which contain 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; (2) a fatty acid component which is at least one selected from the group consisting of lauric acid, isostearic acid, oleic acid, γ-linolenic acid, α-linolenic acid, linoleic acid and salts thereof, and (3) at least one nonionic surfactant selected from the group consisting of glycerol fatty acid esters, organic acid monoglycerides, polyglycerol fatty acid esters, propylene glycol fatty acid esters, polyglycerol condensation ricinolein acid esters, sorbitan fatty acid esters and sucrose fatty acid esters and polyoxyethylene sorbitan fatty acid esters, the amount of the nonionic surfactant being not more than 0.1 times a 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 pH being from 6.2 to 8.
