EMULSION COMPOSITION CONTAINING DOUBLE-STABILIZED CERAMIDE NANO CAPSULE, METHOD FOR MANUFACTURING THE SAME, AND COSMETIC COMPOSITION CONTAINING THE SAME

摘要

Provided are an emulsion composition containing a nanosized (10 to lOOOnm) ceramide capsule particle stabilized by doubly encapsulating with wax matrix and polymer, a preparation method of the emulsion composition, and a skin cosmetic composition using the emulsion composition. More particularly, provided is an emulsion composition having superior stability with time in spite of high ceramide content, which is attained by effectively inhibiting gelling between ceramide molecules through trapping ceramide in solid wax matrix and then en¬ capsulating the wax matrix using polymer. In accordance with the present invention, ceramide, a skin lipid component with excellent moisturizing effect, is prepared into a stable emulsion through being trapped in a nanosized capsule particle, which provides improved dermal delivery and adhesion to skin, and improved and long-lasting moisturizing effect.
