Summary of the Invention

Problems to be Solved by the Invention

[0007] The following analysis is provided from the perspective of this disclosure.

[0008] As in the case of the compact emulsion foundation described in Patent Document 1, when the water content is low, the usability both during and after application to the skin deteriorates. Further, even when the foundation is applied to the skin, a high unevenness correcting effect on the skin cannot be obtained.

[0009] In the solid water-in-oil emulsion makeup base described in Patent Document 2, when dimethylpolysiloxane is volatile, the usability both during and after application to the skin deteriorates. Further, a sufficient unevenness correcting effect cannot be obtained. On the other hand, when dimethylpolysiloxane is non-volatile, the usability after application to the skin deteriorates, and also in this case, a sufficient unevenness correcting effect cannot be obtained. Further, since the solid water-in-oil emulsion makeup base described in Patent Document 2 contains a large amount of pigments, the usability both during and after application to the skin deteriorates. Furthermore, also in this case, a sufficient unevenness correcting effect cannot be obtained.

[0010] Therefore, there is a demand for a solid water-in-oil emulsion cosmetic that provides good usability both during and after application to the skin and has a high unevenness correcting effect.

Non-volatile silicone oils are silicone oils having a viscosity exceeding 5 cSt. volatile Acyclic The volatile silicone oil is 5% by mass to 40% by mass based on the mass of the oily component. The pigment in the powder is 4% by mass or less based on the mass of the solid water-in-oil emulsion cosmetic.

When the proportion of the volatile silicone oil was high (the proportion of the non-volatile silicone oil was low) Comparative Example 2 in Comparative Example 2 , there were few panelists who evaluated that the usability as a whole was good. Also, there were few panelists who evaluated the unevenness correction effect. From this, the ratio of the volatile silicone oil in the oily component is preferably 40% by mass or less, more preferably 35% by mass or less, still more preferably 30% by mass or less, and particularly preferably 25% by mass or less with respect to the mass of the oily component. Also, the ratio of the volatile silicone oil in the oily component is preferably 5% by mass or more, and more preferably 10% by mass or more with respect to the mass of the oily component.

On the other hand, when the water content was about 51% by mass wherein the content of the aqueous phase is 68.35% by mass In Example 7, a stable solid oil-in-water type emulsified cosmetic was obtained. It is considered that the stability of the cosmetic decreased because the water phase was too much. From this, it is considered that the water phase is preferably 65% by mass or less, and more preferably 63% by mass or less with respect to the mass of the cosmetic.

[0117] The water content was about 16% by mass wherein the content of the aqueous phase is 26.35% by massIn Comparative Example 5, there were many panels that did not evaluate the feel on the skin during application.
