Abstract
The present invention concerns stabilized cosmetic material containing triple-encapsulated retinal. Unstable, fat-soluble retinal is stabilized firstly by addition into vesicles consisting of nonionic surface-active agent, cholesterol and cholesteryl ester. The firstly stabilized retinol (vesicle) is subsequently inserted into sphingosomes (a kind of multi lamellar liposome) consisting of lecithin and ceramide. Finally the double-encapsulated retinal (sphingosome) is inserted into lamellar liquid-crystal emulsifying base, thereby being triply encapsulated.
