Description

  The present invention relates to a water-in-oil emulsion phase makeup composition. Specifically, the present invention relates to a makeup composition comprising a specific amount of ingredients that provide the benefits of both a solid foundation and a liquid foundation. The present invention also relates to a makeup composition comprising a water-soluble skin treatment agent such as niacinamide.

(Background of the Invention)
The foundation composition can be applied to the face and other parts of the body to make the skin tone and texture uniform and hide pores, wrinkles and the like. Foundation compositions are also applied to moisturize skin, condition skin oils, and protect skin from the adverse effects of sunlight, wind, and other environmental factors.

  Foundation compositions are generally available in the form of liquid or cream suspensions, emulsions, gels, solid powders, or anhydrous oil and wax compositions. The liquid emulsified foundation is suitable in that it can moisturize the skin by including water and a water-soluble skin treatment agent. However, such a liquid-like foundation lacks convenience for consumers in terms of use and carrying. On the other hand, a compactly loaded solid foundation is easy to use for consumers but is generally less effective than a liquid foundation in terms of moisturizing the skin and hiding defects.

So far, solid and water-in-oil emulsion foundation compositions have been proposed. These emulsified solid foundations can be placed in a wide variety of packages, including compacts, and are becoming increasingly popular among Asian consumers. References disclosing such foundation compositions are Japanese Patent No. 2-88511, Japanese Patent No. 3-261707, and US Pat. No. 5,362,482. Such emulsified solid foundations have been successful, covering the disadvantages of conventional liquid foundations and solid foundations to some extent, but further improvements are also desired. For example, it is known that when the amount of water and a component for moisturizing the skin is increased, the freshness and light texture of the skin may be lost. Further, it is known that when the amount of a component that provides smoothness and good elongation during application is increased, the appearance of the skin becomes powdery. Furthermore, even when making the desired improvements, foundation products must be stable over the typical shelf life of these foundations and must be manufacturable at a reasonable cost.
In view of the foregoing, there is a need for a makeup composition that is solid at room temperature, provides a high moisturizing effect on the skin, has good elongation, and leaves a fresh and light feel on the skin.
