Description

The present invention relates to a sunscreen cosmetic that is not sticky due to an ultraviolet absorber, has excellent flexibility of a cosmetic film, spreads smoothly, and has an excellent smooth feel after application. In more detail, the present invention relates to porous anhydrous silicic acid. The present invention relates to a sunscreen cosmetic containing an organic ultraviolet absorber, a volatile oil agent, a partially crosslinked organopolysiloxane polymer and an organic spherical powder.

In general, sunscreen cosmetics are often used during the day and are very useful because they do not cause sunburn or tanning. In particular, when playing sports outdoors, it may be required not only to have an ultraviolet protection effect, but also to have a flexible makeup film that does not collapse even with vigorous movement. Furthermore, in recent years, there has been an increasing demand for sunscreens that not only have functionality but also have a good feeling of use, and that they have a smooth and good feeling of use without feeling any discomfort such as stickiness after application, and that they are applied over a wide range. Good spread is required to spread.

On the other hand, in order to obtain a high UV protection effect, it is customary to contain a large amount of UV scattering agents and UV absorbers. However, it is known that when a large amount of an ultraviolet scattering agent is contained, whitening after application and squeaking during use are likely to occur, and when a large amount of an ultraviolet absorbing agent is contained, oiliness and stickiness are easily felt. In particular, many UVA absorbers are solid and sparingly soluble at room temperature (slightly soluble in both water and non-polar oils). Therefore, by increasing the content of the oil agent and the surfactant, it is possible to contain a large amount of the sparingly soluble ultraviolet absorber, but there is a problem that stickiness is likely to occur. Various studies have been made to improve the usability of sunscreens having a high UV protection effect for the above problems. For example, a sunscreen cosmetic containing 10% by mass or more and 25% by mass or less of an ultraviolet absorber contains powder in an amount of 10% by mass or more and 30% by mass or less, resulting in a sticky feeling caused by containing the ultraviolet absorber. (Refer to Patent Document 1), and a technique to obtain cosmetics with good usability by using isododecane and dodecamethylcyclohexasiloxane as volatile oils (see Patent Document 2). ..

Japanese Unexamined Patent Publication No. 2013-184900 Japanese Unexamined Patent Publication No. 2012-46447

However, in the technique of Patent Document 1, although the stickiness due to the ultraviolet absorber can be suppressed by containing a large amount of powder, squeaks occur during use, and the flexibility of the decorative film that can withstand more violent movement is satisfied. I couldn't get anything. Further, in the technique of Patent Document 2, although a feeling of use that stretches smoothly can be obtained by containing a specific volatile oil agent, it feels oily after application, and withstands a smooth feeling of use and even more violent movement. I was not satisfied with the flexibility of the cosmetic film I got. Therefore, while the conventional technology has a high UV protection effect, it is not sticky due to the UV absorber, spreads smoothly, has a smooth feel after application, and has the flexibility of a cosmetic film that can withstand violent movements. No excellent sunscreen cosmetics were obtained. Therefore, the present invention has the flexibility of a decorative film that can withstand violent movements, has a high ultraviolet protection effect, is not sticky due to an ultraviolet absorber, has excellent flexibility of the decorative film, and spreads smoothly. The object is to provide a sunscreen cosmetic that has a smooth feel after application.

As a result of diligent studies, the present inventors have made stickiness due to the organic ultraviolet absorber by using porous anhydrous silicic acid having a large oil absorption, a volatile oil agent, a partially crosslinked organopolysiloxane polymer, and an organic spherical powder. We have found that we can obtain a sunscreen cosmetic that has the flexibility of a cosmetic film that can withstand violent movements, spreads smoothly, and has a smooth feel after application, and has completed the present invention. rice field.

As is clear from the results in Tables 1 to 3, the water-in-oil sunscreen of the example was not sticky due to the ultraviolet absorber, had excellent flexibility of the cosmetic film, spread smoothly, and became smooth after application. It was excellent in usability. On the other hand, in Comparative Example 1 containing no component (A), a satisfactory one was not obtained in terms of the flexibility of the cosmetic film and the smooth feeling of use after application. In Comparative Example 2 in which the component (A) was replaced with non-porous anhydrous silicic acid, a smooth feeling of use after application was not obtained. Further, in Comparative Example 3 in which the component (C) is replaced with a non-volatile oil, the proportion of the non-volatile oil on the skin is large, so that the spread is inferior to that of the volatile oil, and the feeling of use after application is smooth. I couldn't get a satisfactory one. Further, in Comparative Example 4 containing no component (D) and Comparative Example 5 in which the coating film was replaced with another film-forming agent, the flexibility of the decorative film was not satisfactory. In Comparative Example 6 in which the component (E) was replaced with a plate-shaped organic powder, no satisfactory result was obtained in terms of good spreadability.
