Description

  The present invention relates to a water break type sunscreen cosmetic. In addition, in this invention, the composition for cosmetics may be described as cosmetics.

  In the case of sunscreen cosmetics, organic UV absorbers such as ethylhexyl methoxycinnamate are used in order to provide an ultraviolet protection effect, but these have poor compatibility with silicone, so that the stabilization of silicone-based cosmetics is difficult. difficult. For this reason, when the organic ultraviolet absorber is blended in a high amount, the feeling becomes poor, and there are problems such as discoloration and odor.

  In recent years, as sunscreen measures in daily life, oil-in-water sunscreen cosmetics that are easy to use continuously with a refreshing feeling of use, and cosmetics that do not deteriorate the feel of organic UV absorbers have been developed ( Patent Document 1: Japanese Patent Application Laid-Open No. 2013-91625). However, the oil-in-water type cosmetic has a problem that it has low water resistance and easily falls off due to exposure to sweat, water and the like.

  On the other hand, in order to obtain a water-in-oil type cosmetic having a fresh feel, it is possible to prepare a high water content emulsion having a large particle size by using a partially crosslinked polyether-modified silicone to obtain a cosmetic having a fresh feel. It is known (Patent Document 2: JP-A-2001-2521). It is also known that a water break type cosmetic can be prepared by designing such a large particle size emulsion particle size.

Further, there is known a technique for obtaining a fresh sunscreen cosmetic by using an ultraviolet scattering agent or an absorbent in combination with a water-in-oil cosmetic having a high internal aqueous phase (Patent Document 3: Japanese Patent Application Laid-Open No. 2009-242294). Gazette). However, since an active agent is blended in excess with respect to the ultraviolet light scattering agent, a water break feeling is not felt, and no studies have been made on the relationship between the ratio and freshness. Further, a technique for obtaining a water-in-oil type water break type cosmetic containing an ultraviolet absorbent is also known (Patent Document 4: Japanese Patent Application Laid-Open No. 2011-219448). However, no studies have been conducted containing ultraviolet scattering agents.
In view of the above, research on a water-break type sunscreen cosmetic which contains an ultraviolet scattering agent, has a good feel, has high water resistance, and can impart a fresh feeling of use has been desired.

It was evaluated by panelists. The evaluation was performed according to the evaluation criteria shown in Table 1, and the results were determined based on the average value of 10 persons according to the following criteria. The results are shown in Tables 2 to 4.

  From the results in Tables 2 and 4, the water-break type sunscreen cosmetics of Examples 1 to 6 show the stability of the cosmetic (50 ° C. for one month), the feeling of water break (the degree of water droplet popping), and the elongation (extension). It was found that ductility), feeling of use (non-stickiness), and water resistance (hardness to drop by sweat) were good. Further, from the results in Table 4, it was found that Example 5 in which the component (b) as a dispersant was a non-crosslinked polyglycerin-modified silicone had a more water-breaking feeling.

  Comparative Example 1 in which the component (a) of the present invention was not blended had poor stability because of poor emulsification. In Comparative Examples 3 and 4 in which the blending amount of the component (b) is large, and in Comparative Example 6 in which (b) / (d) is more than 0.4, a water break feeling is not felt, and (b) / (d) is 0.1%. Comparative Example 7, which is less than 05, has poor stability and elongation. Satisfactory characteristics cannot be obtained in Comparative Example 5 in which the amount of the component (c) is small, or in Comparative Example 8 in which an ultraviolet scattering agent not subjected to a hydrophobic treatment is used instead of the component (d). Also, from the results of Comparative Example 2, a trace amount of the component (b) contributed to the improvement of stability.
