Description

Water break type sunscreen cosmetics

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

In the case of sunscreen cosmetics, organic UV absorbers such as ethylhexyl methoxycinnamate are used to impart UV protection effects, but these have poor compatibility with silicone, so stabilization of silicone cosmetics is difficult. For this reason, when the organic ultraviolet absorber is highly blended, the feel is also deteriorated, and there are also problems such as discoloration and a change in odor.

In recent years, as a sunscreen measure in daily life, an oil-in-water sunscreen that is easy to use continuously with a refreshing feeling of use, and a cosmetic that does not deteriorate the feel of the organic UV absorber has been developed ( Patent Document 1: Japanese Patent Application Laid-Open No. 2013-91625). However, the oil-in-water cosmetic has low water resistance and is prone to being removed by exposure to sweat or water.

On the other hand, in order to obtain a water-in-oil type cosmetic with a fresh feel, it is possible to prepare an emulsion with high water content and large particle size using partially cross-linked polyether-modified silicone to obtain a cosmetic with a fresh feeling of use. It is known (patent document 2: Unexamined-Japanese-Patent No. 2001-2521). It is also known that water break type cosmetics can be prepared by designing such a large particle size emulsion particle size.

Furthermore, there is known a technique for obtaining a fresh sunscreen cosmetic by using an ultraviolet light scattering agent or an absorbent together with a water-in-oil cosmetic having a high internal water phase (Patent Document 3: JP 2009-242294 A). Gazette). However, since the active agent is compounded in excess with respect to the ultraviolet light scattering agent, no feeling of water break is felt, and no research has been made on the relationship between the ratio and freshness. There is also known a technique for obtaining a water-in-oil type water-breaking cosmetic composition containing an ultraviolet absorber (Patent Document 4: Japanese Patent Application Laid-Open No. 2011-219448). However, no studies have been made to contain UV scattering agents.
From the above, it is desired to research a water-break type sunscreen cosmetic which contains an ultraviolet light scattering agent, which is good in feel, water resistance, and can give a fresh feeling of use.

From the results of Tables 2 and 4 above, the water-break type sunscreen cosmetics of Examples 1 to 6 have stability of the cosmetic (50.degree. C., 1 month), a feeling of water break (dropping of water droplets), elongation (expansion) It was found that ductility), feeling in use (no stickiness) and water resistance (resistance to sweating) were good. Further, from the results of Table 4 above, it was found that the water break feeling was felt more in Example 5 in which the component (b) as the dispersant was non-crosslinked type polyglycerin-modified silicone.

In Comparative Example 1 in which the component (a) of the present invention was not blended, the stability was not preferable because the emulsified state was bad. In Comparative Examples 3 and 4 in which the compounding amount of the component (b) is large and Comparative Example 6 in which (b) / (d) exceeds 0.4, no feeling of water break is felt, and (b) / (d) is 0. In Comparative Example 7 which is less than 05, the stability and elongation are poor. Satisfactory properties can not be obtained in Comparative Example 5 in which the compounding amount of the component (c) is small or in Comparative Example 8 in which an ultraviolet light scattering agent which is not hydrophobized is used instead of the component (d). Further, from the results of Comparative Example 2, a small amount of the component (b) contributed to the improvement of the stability.
