Description

Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to a water-in-oil type emulsion phase type makeup composition. Specifically, the present invention relates to make-up compositions containing specified amounts of ingredients that provide the benefits of both solid and liquid foundations. The present invention also relates to a makeup composition containing a water-soluble skin treatment agent such as niacinamide.

BACKGROUND OF THE INVENTION A foundation composition is one that can be applied to the face and other parts of the body to even out the tone and texture of the skin and to hide pores, wrinkles and the like. The foundation composition is also applied to moisturize the skin, condition the oil on the skin, and protect the skin from the harmful effects of sunlight, wind, and other environmental factors.

Foundation compositions are generally liquid or creamy suspensions, emulsions,
Available in the form of gels, solid powders, or anhydrous oil and wax compositions. The liquid emulsion type foundation is suitable in that it can moisturize the skin by containing water and a water-soluble skin treatment agent. However, such liquid foundations are not convenient for consumers to use and carry. On the other hand, compactly loaded solid foundations are easy for consumers to use, but are generally less effective than liquid foundations in moisturizing the skin and concealing imperfections.

So far, solid, moreover, water-in-oil type emulsion compositions have been proposed. These emulsified solid foundations can be packaged in a wide variety of packages, including compact ones, and are becoming increasingly popular with Asian consumers. References disclosing such foundation compositions include Japanese Patent No. 2-
88511, Japanese Patent No. 3-261707, and US Patent No. 5,362,4.
No. 82. Such an emulsified solid foundation covers the drawbacks of conventional liquid foundations and solid foundations to some extent and has been successful, but further improvements are desired. For example, it is known that increasing the amount of water and a component for moisturizing the skin may cause loss of freshness and light texture of the skin. It is also known that when the amount of a component that provides smoothness and good spreadability when applied is increased, the appearance of the skin becomes powdery. In addition, even with the desired improvements, foundation products must be stable over the typical shelf life of these foundations and must be able to be manufactured at a reasonable cost. From the above, there is a need for a make-up 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.

SUMMARY OF THE INVENTION The present invention provides (a) about 25 wt% to about 40 wt% volatile silicone oil, and (b) about 0.5 wt% to about 8 wt% non-volatile oil. (C) about 1 wt% to about 5 wt% solid wax, (d) about 1 wt% to about 5 wt% lipophilic surfactant having an HLB value of less than about 8, and (e) ) About 25% to about 35% by weight of hydrophobically treated pigment, and (f) volatile silicone oil and water in an amount such that the total amount of water is at least about 50%, solid at room temperature, The present invention relates to a water-in-oil type emulsion make-up composition that satisfies the requirements for a make-up composition that provides a high moisturizing effect to the skin while having good elongation and leaving a fresh and light feeling on the skin. Those skilled in the art will be able to ascertain these and other features, aspects, and advantages of the present invention by reading the present disclosure and the appended claims.
