Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid cosmetic for exclusive use of water, such as using a sponge or the like impregnated with water at the time of use, or directly mixing with water. Good mixability with powder and refreshing feeling
The present invention relates to a solid powder cosmetic exclusively for water use, which has good spread on the skin and excellent makeup persistence.

[0002]

2. Description of the Related Art Conventionally, as a solid powder cosmetic which is excellent in a refreshing feeling and a long lasting makeup at the time of use, a solid powder cosmetic exclusively used for water used in a sponge impregnated with water has a so-called cake foundation. Was. Here, the conventional solid powder cosmetic for exclusive use of water contains a hydrophilic nonionic surfactant in order to favorably mix water and powder. However, when a hydrophilic surfactant is blended, the durability of the makeup may be reduced. In order to compensate for this, it is necessary to blend a hydrophilic coating agent such as polyvinyl alcohol in addition to the hydrophilic surfactant. And Japanese Patent Application Laid-Open No. Hei 10-31637. Japanese Patent Application Laid-Open No. 5-178 discloses a method of blending a polyoxyalkylene-modified organopolysiloxane in order to improve the cosmetic durability of a solid powder cosmetic.
No. 722.

[0003]

However, when a hydrophilic nonionic surfactant and a hydrophilic coating agent are blended,
Although the cosmetic continuity is improved to some extent, the spread of the hydrophilic coating agent is poor because the hydrophilic coating agent holds water at the time of application, and the finished decorative film lacks flexibility. Further, the technology disclosed in JP-A-5-178722 discloses that the polyoxyalkylene-modified organopolysiloxane absorbs moisture from the skin after application of the cosmetic, and thickens, thereby enhancing the durability of the makeup. This technology is different from water-only cosmetics that are mixed with water when used. Therefore, there has been a demand for the development of a solid powder exclusively for water use, which has good solubility in water, high refreshing sensation, good spread and spread on the skin, and excellent makeup persistence.

[0004]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that non-silicone anionic surfactants, non-silicone nonionic surfactants,
By combining three different surfactants of silicone-based surfactants and powders, the miscibility of water and powder is good, the refreshing feeling is high, the spread on the skin is good, the makeup is good The present inventors have found that a solid powder cosmetic exclusively for water use having excellent durability can be obtained, and completed the present invention.

That is, the present invention provides the following components (a) to
(D); component (a) non-silicone anionic surfactant component (b) non-silicone nonionic surfactant component (c) silicone surfactant component (d) powder containing water-only solid The present invention relates to powder cosmetics. Further, the component (b) non-silicone nonionic surfactant comprises a non-silicone nonionic surfactant of HLB11 or more and a non-silicone nonionic surfactant of less than HLB11. The present invention relates to a solid powder cosmetic exclusively used for water, which is a surfactant. Still further, the present invention relates to the solid powder cosmetic exclusively used for water, wherein the component (a) the non-silicone anionic surfactant is polyoxyethylene alkyl ether phosphoric acid or a salt thereof.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
