Description

Technical Field

[0001] The present invention relates to a water-in-oil emulsified cosmetic containing an ultraviolet scattering agent. Background Art

[0002] Cosmetics applied directly to the skin are expected to give the skin a comfortable feeling of use such as moist, moist, and smooth when applied. Various methods have been studied to achieve such a feeling of use, but it is known that the feeling of use in cosmetics varies depending on the emulsification technology, and the most suitable emulsification technology has been studied. In such research, it is known that among water-in-oil cosmetics, cosmetics with a high ratio of water phase are excellent in being able to give a moist feeling.

[0003] In water-in-oil cosmetics, use of specific silicone-based surfactants and specific sucrose fatty acid esters as emulsifiers has been studied (for example, Patent Document 1).

[0004] In cosmetics with sunscreen effects, ultraviolet absorbers and ultraviolet scatterers are added as a means of protecting the skin from ultraviolet rays. In water-in-oil cosmetics with a high internal water phase, high amounts of ultraviolet absorbers have been proposed to enhance the ultraviolet protection effect. If the amount of ultraviolet absorbers added increases, there is a concern that the usability and stability may be reduced due to stickiness, etc.
