First claim
Opening claim text (preview).
What is claimed is: 1. A ceramide dispersion composition, comprising: at least one ceramide represented by Formula (1) or Formula (2); a surfactant; and trisodium ascorbyl palmitate phosphate: wherein, in Formula (1), R 1 represents an aliphatic hydrocarbon group having at least one unsaturated double bond, R 2 represents an alkyl group having 9 or more carbon atoms, and n represents an integer from 20 to 34; and in Formula (2), R 3 represents an aliphatic hydrocarbon group having at least one unsaturated double bond, R 4 represents an alkyl group having 9 or more carbon atoms, m represents an integer from 20 to 34, and X represents a hydrogen atom or a hydroxyl group. 2. The ceramide dispersion composition according to claim 1 , wherein the aliphatic hydrocarbon group having at least one unsaturated double bond represented by R 1 or R 3 has 15 or more carbon atoms. 3. The ceramide dispersion composition according to claim 1 , wherein the aliphatic hydrocarbon group having at least one unsaturated double bond represented by R 1 or R 3 has from 1 to 3 double bonds. 4. The ceramide dispersion composition according to claim 1 , wherein the surfactant comprises a nonionic surfactant. 5. The ceramide dispersion composition according to claim 1 , further comprising lecithin. 6. The ceramide dispersion composition according to claim 1 , further comprising cholesterol. 7. The ceramide dispersion composition according to claim 1 , wherein a content of trisodium ascorbyl palmitate phosphate with respect to a content of the at least one ceramide represented by Formula (1) or Formula (2) is from 1 time by mass to 8 times by mass. 8. The ceramide dispersion composition according to claim 1 , wherein a content of the surfactant with respect to a content of the at least one ceramide represented by Formula (1) or (2) is from 1 time by mass to 70 times by mass. 9. The ceramide dispersion composition according to claim 1 , which is an external agent for skin.
