Description

A lip cosmetic composition comprising an oil-containing microcapsule,

More particularly, the present invention relates to a lip cosmetic composition comprising an oil-containing microcapsule, and more particularly, to a lip cosmetic composition comprising an oil-containing microcapsule and an oil-containing microcapsule dispersed therein, To a lip cosmetic composition.

Lips are thinner than other skin in the body, have no sebaceous glands, and are less likely to retain moisture and tend to dry out. Lip makeup compositions used for lips such as lipsticks, lip gloss, lips tint and lip balm have various nutritional ingredients, organic and inorganic pigments in oily materials such as vegetable wax, ester oil and the like to protect lips while showing beautiful lips .

In general, lipstick consists of oil, wax, and pigment ingredients. Among these components, the wax serves to maintain the hardness of the product and to prevent product deformation due to external temperature changes. However, due to the wax component, colors are difficult to be expressed clearly and there is a limit to giving sufficient moisturizing effect to the lips which are easy to dry.

Lip Gloss is mainly composed of oily components and can not contain water inside, so it can not supply water and moisturizing ingredients to the lips. It has a feeling of being bundled and sticky. In other words, lipstick and lip gloss have been used to improve passive moisturizing properties by the effect of blocking the oil component of the lip to prevent the evaporation of water by forming an oil film on the lip.

Lip gloss, which is composed only of water-based ingredients, has been developed to positively improve the moisturizing properties of lips, provide excellent color development, and provide a tactile feeling. However, the above-mentioned lipgloss made of an aqueous component has a sufficient water supply, but the effect of preventing evaporation of water due to the absence of an oily component is insufficient and the lips are quickly matted.

Accordingly, development of a lip cosmetic composition that continuously imparts moisturizing power has been desired.

On the other hand, microcapsules are used as a base technology in various fields such as medicines, paints, electronic industry, and cosmetics, and are used as the best tools to maintain the initial activity of drugs when they are used in medicines and cosmetics (Journal of controlled release, 58, 9, 1999).

Microencapsulation in cosmetic formulations has several advantages. Microcapsules protect sensitive materials from deterioration and serve as controlled release means for active materials.

This encapsulation technique consists of an agitation process, a compaction process, a layering process, and a globulation process. More specifically, the agitation process is balling, the compression process is compression compression and extrusion / spheronization; the layering process is solution / suspension and powder; and the spheroidizing process is spray drying and spray congealing. .

However, such microcapsules have a problem that the internal structure is densely formed, the content of the active ingredient in the capsules is small, and in the case of porous microcapsules, water easily penetrates into the capsules in an aqueous solution, resulting in degradation of the active ingredient.

Furthermore, in order to apply the microcapsule to a cosmetic preparation, the physicochemical stability of the microcapsule itself and the stability of the active ingredient trapped in the microcapsule itself are variable at the same time for variables of surrounding environment such as moisture, surfactant, It is a fact that it has not yet presented a solution to this problem.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a lip cosmetic composition which imparts excellent stability and moisturizing power.

In order to accomplish the above object, the present invention provides a lip cosmetic composition comprising oil-containing microcapsules.
