Abstract:
The present invention is to provide a vesicle composition comprising the following components (A), (B) and (C): (A) 0.0001 to 20 mass % of an organic acid represented by general formula (1): wherein R1 represents a natural sterin having a single hydroxy group or a hydrogenated product thereof or a residue which remains after a hydrogen atom is removed from the hydroxy group of bile acid, R2 represents a divalent hydrocarbon group having 1 to 24 carbon atoms, M represents a hydrogen atom, an alkali metal, an alkali earth metal, ammonium, an alkanolammonium having 2 to 9 carbon atoms in total, an alkylammonium or alkenylammonium having 1 to 22 carbon atoms in total, pyridinium substituted with an alkyl group or alkenyl group having 1 to 18 carbon atoms or a basic amino acid, (B) 0.0001 to 10 mass % of a sphingosine, and (C) water, and having a pH of 2 to 11.
