Accordingly, the solid cosmetic composition has excellent aesthetic effect, stability in a manufacturing process, and functional effect.

Description

SOLID COSMETIC COMPOSITION COMPRISING MICROCAPSULE CONTAINING FUNCTIONAL COMPONENT < RTI ID = 0.0 >

The present invention relates to a solid cosmetic composition comprising microcapsules containing a functional ingredient and more particularly to a cosmetic composition containing microcapsules containing a functional ingredient, Microcapsules capable of containing a relatively large amount of a functional ingredient and capable of releasing a functional ingredient which is not destroyed in the manufacturing process but is destroyed when applied to the skin.

Solid cosmetics generally have a slight difference depending on the form of the formulation, but generally include oily ingredients, color imparting and powder ingredients used to cover skin imperfections, wax and oil ingredients used to increase hardness and formulation stability, and A water-soluble component that moisturizes the skin, and the like, and may contain various functional ingredients and the like as needed.

Among them, the functional ingredient is drastically deteriorated when exposed to the external environment such as light, heat or water, and in particular, when it is desired to give an effect to the cosmetic formulations, the functional ingredient is dissolved in the water-soluble component, oil component, Since denaturation is caused by the same additive, means are required to block stimulation from the external environment and / or reaction with the contained components.

Further, in the solid cosmetic composition, when the temperature is rapidly changed to a high temperature, the oil phase component escapes to the surface of the formulation, causing a sweating phenomenon such as sweat or water droplets, need.

Thus, there has been an attempt to increase the stability by incorporating functional or oil components therein using microcapsules. For example, Korean Patent Laid-Open Publication No. 2006-0072533 discloses a technique for producing polymer microcapsules to enhance the stability of vitamin K1 as a functional ingredient. However, the polymer microcapsules disclosed in the above document have a limit of natural oil bearing ratio of 10%, which is very low.

In addition, there have been attempts to use microcapsules in basic cosmetics such as creams and lotions. However, when such a trial is applied to a solid cosmetic composition as it is, the solid cosmetic composition is filled with a high temperature at the time of manufacturing a formulation using the solid cosmetic composition, so that the capsule membrane is easily cracked and the microcapsule is not dispersed evenly There were additional problems to be brought together. For example, when microcapsules are injected into a viscous medium such as an emulsion or a cream, and the microcapsules are used in a formulation prepared by stirring at a high speed, microcapsules are destroyed in the manufacturing process.

Therefore, there is a need to develop microcapsules and solid cosmetic compositions containing them that are not destroyed in the production process of the solid cosmetic composition.
