[0028] Example 1 and Comparative Examples 1-3: Preparation of Stable Ceramide Emulsion Compositions Using Wax and Polymer Components

[0029]The oily ingredients (#1-3) given in Table 1 were mixed in a separate vessel while heating to 70°C and dispersed using a homogenizer to prepare a lipophilic mixture. The aqueous ingredients (#4-6) were mixed while heating to 70°C and emulsified at 70°C by slowly adding the lipophilic mixture to the aqueous ingredients. After emulsification, it is quenched in an ice bath, followed by the addition of preservatives. Finally, the emulsion composition was put into a sealed container and cooled to room temperature using a cooler.

[0038] In order to evaluate the moisturizing effect of stabilized ceramide nanocapsules, the composition of Example 1 was used to prepare the basic part of ceramide capsules (emulsion type), and it was added to ordinary emulsion (OVA) type cosmetic compositions (Example 2 and In Comparative Example 4) and gel-type cosmetic compositions (Example 3 and Comparative Example 5), the components in Table 3 (unit: weight percent) were used for preparation at a concentration of 10%. However, the concentration of stabilized ceramide capsules is not limited to this specific example.

Abstract

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 not 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.

Description

technical field [0001] The present invention relates to an emulsion composition comprising nanoscale (10-1000nm) capsule particles, wherein ceramides are stabilized by double encapsulation with wax and polymer, a method for preparing the emulsion composition, and the use of the emulsion combination skin cosmetic composition. Specifically, the present invention relates to an emulsion composition that maintains excellent stability over a long period of time even at a high ceramide content by coating the ceramide with a wax and then coating it with a polymer This is achieved by encapsulating the wax matrix, thereby effectively inhibiting the gelation between ceramide molecules. Background technique [0002] In general, cosmetics are used to keep the human body clean, improve appearance, protect skin or hair from problems such as ultraviolet radiation, dryness, and prevent aging. With the industrialization of society and the increase of social activities, people are more and m...
