The following analysis is given from the perspective of this disclosure.

If the water content is low, as in the compact emulsified foundation described in Patent Document 1, the feeling of use both during and after application to the skin deteriorates. Further, even if the foundation is applied to the skin, a high unevenness correction effect on the skin cannot be obtained.

In the solid oil-in-water emulsified makeup base described in Patent Document 2, when dimethylpolysiloxane is volatile, the feeling of use both at the time of application to the skin and after application is deteriorated. In addition, a sufficient unevenness correction effect cannot be obtained. On the other hand, when dimethylpolysiloxane is non-volatile, the feeling of use after application to the skin is deteriorated, and in this case as well, a sufficient unevenness correction effect cannot be obtained. Further, since the solid-type water-in-oil emulsified makeup base described in Patent Document 2 contains a large amount of pigment, the feeling of use both at the time of application to the skin and after application is deteriorated. Further, even in this case, a sufficient unevenness correction effect cannot be obtained.

In Test Examples 1 to 4, the total amount of the oily component and the silicone oil was kept constant, and the ratio of the volatile silicone oil to the non-volatile silicone oil was changed. In Test Example 2 in which the proportion of volatile silicone oil was high (the proportion of non-volatile silicone oil was low), few panels evaluated that the usability was good as a whole. In addition, there were few panels that 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, and more preferably 30% by mass or less with respect to the mass of the oily component. , 25% by mass or less is considered to be more preferable. Further, the ratio of the volatile silicone oil to the oily component is preferably 5% by mass or more, and more preferably 10% by mass or more, based on the mass of the oily component.

Looking at the ratio of the volatile silicone oil to the non-volatile silicone oil, the amount of the non-volatile silicone oil is preferably 0.8 parts by mass or more, preferably 1.5 parts by mass or more, based on 1 part by mass of the volatile silicone oil. It is more preferable that there is, and it is considered that it is more preferable that the amount is 2 parts by mass or more. The amount of the non-volatile silicone oil is preferably 10 parts by mass or less, more preferably 9 parts by mass or less, more preferably 7 parts by mass or less, and 5 parts by mass or less with respect to 1 part by mass of the volatile silicone oil.

From this, it is considered that the volatile silicone oil is preferably a non-cyclic silicone oil rather than a cyclic silicone oil.

In Test Examples 5 to 8, the water content was changed. The silicone oil content was changed according to the water content. The ratio of the volatile silicone oil to the non-volatile silicone oil was the same as in Test Example 3.

In Test Example 8 in which the water content was about 59% by mass, a stable water-in-oil emulsified cosmetic in solid oil could not be obtained. On the other hand, in Test Example 7 having a water content of about 51% by mass, a stable solid water-in-oil emulsified cosmetic was obtained. It is probable that the stability of the cosmetics decreased because there were too many aqueous phases. From this, it is considered that the aqueous phase is preferably 65% by mass or less, and more preferably 63% by mass or less, based on the mass of the cosmetic.

In Test Example 5 in which the water content was about 16% by mass, there were many panels that did not evaluate the usability felt by the skin at the time of application. In particular, few panels felt freshness. In addition, there were few panels that evaluated the unevenness correction effect and the resistance to kinking of the base cosmetic. It is considered that these were influenced by the small amount of aqueous phase. From this, it is considered that the aqueous phase is preferably 30% by mass or more, more preferably 35% by mass or more, and further preferably 40% by mass or more.

The cosmetics according to Test Examples 1 to 8 contain paraffin wax, which is a linear hydrocarbon, and microstalin wax, which is a branched hydrocarbon, as wax. In Test Examples 9 to 10, based on the composition according to Test Example 3, the total amount of wax was the same as in Test Examples 1 to 8, and only one of the linear hydrocarbon and the branched hydrocarbon was added.

Good evaluation was obtained in both Test Example 9 to which no branch wax was added and Test Example 10 to which no linear wax was added.

In Test Example 9 to which no branch wax was added, the number of panels showing the unevenness correction effect was smaller than that in Test Example 3. On the other hand, in Test Example 10 to which the linear wax was not added, the number of panels in which good elongation at the time of application and freshness after application were observed was smaller than that of Test Example 3. From this, it is considered that the water-in-water emulsified cosmetic in solid oil preferably contains both the linear wax and the branched wax. The linear wax is preferably 3% by mass or more, more preferably 3.5% by mass or more, and further preferably 4% by mass or more. The linear wax is preferably 6% by mass or less, more preferably 5.5% by mass or less, and further preferably 5% by mass or less. The branched wax is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, and further preferably 0.25% by mass or more. The branched wax is preferably 0.6% by mass or less, more preferably 0.5% by mass or less, and further preferably 0.4% by mass or less.

In Test Examples 11 to 14, the amount of pigment was changed based on the composition according to Test Example 3.

In Test Example 11 in which the pigment content was 0.5% by mass, a good evaluation was obtained. Compared with Test Example 12 in which the pigment content was 2% by mass, Test Example 12 had a better evaluation of the unevenness correction effect. From this, the pigment is preferably 0.1% by mass or more, more preferably 0.2% by mass or more, more preferably 0.4% by mass or more, and more preferably 0.7% by mass or more. It is considered to be more preferable.

In Test Examples 13 and 14 in which the pigments were 4% by mass and 6% by mass, as the number of pigments increased, the number of people evaluating the usability generally decreased, and the number of people evaluating the unevenness correction effect also decreased. From this, it is considered that the pigment is preferably 4% by mass or less, and more preferably 3% by mass or less.

In Test Examples 15 to 17, the type of light scattering powder was changed based on the composition according to Test Example 3. Polymethylsilsesquioxane powder, nylon-12 powder, silica, and (dimethicone / vinyldimethicone) crosspolymer powder can all function as light scattering powders.

In all of Test Examples 15 to 17, good evaluation was obtained in the same manner as in Test Example 3. From this, it is considered that each evaluation item does not depend on the type of light scattering powder.

In Test Examples 18 to 21, the total amount of powder was changed by changing the amount of light-scattering powder. In Test Example 18 in which the total amount of the powder was 3% by mass, the evaluation as a base cosmetic was lower than that in Test Example 3. From this, it is considered that the total amount of the powder is preferably 1% by mass or more, more preferably 3% by mass or more, and further preferably 5% by mass or more. Further, the light scattering powder is preferably 1% by mass or more, more preferably 3% by mass or more, and further preferably 5% by mass or more.

In Test Example 21 in which the total amount of powder was 19% by mass, the evaluation of freshness after application was low and the evaluation of transparency was also low. From this, it is considered that the total amount of the powder is preferably 18% by mass or less, and more preferably 17% by mass or less. Further, the light scattering powder is preferably 17% by mass or less, and more preferably 16% by mass or less.
