Description

[Technical Field]

[0001] The present invention relates to a water-in-oil emulsion composition. [Background technology]

[0002] In order to protect the skin from the harmful effects of ultraviolet rays, skin cosmetics that provide high UV protection have been sought, and cosmetics that not only have UV protection effects but also have excellent usability and stability have been studied. In particular, water-in-oil emulsion cosmetics are widely used because they are resistant to sweat and sebum and can efficiently distribute oil-soluble active ingredients on the skin. For example, Patent Document 1 describes that a water-in-oil emulsion cosmetic containing an ultraviolet absorber, a non-volatile polar oil having an ester bond, and an oil phase thickener has a high ultraviolet protection effect, does not leave a white cast, and is highly versatile.

[0003] [Patent Document 1] International Publication No. 2018 / 225768 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional water-in-oil emulsion cosmetics have not been fully satisfactory in terms of UV protection effect in light of the recently tightened SPF standards, makeup durability, and the like. Furthermore, when a film-forming agent is blended, there is a problem with the skin's ability to follow the movement of the skin after application. [Means for solving the problem]

[0005] The present inventors have discovered that by using a silicone oil having an alkyl group attached thereto, together with a film-forming agent, a solid organic UV absorber, and an ester oil, it is possible to obtain a water-in-oil emulsion composition that has a high UV protection effect, excellent makeup retention, excellent skin-following ability to conform to skin movement, and excellent pore-blurring effect.

[0006] The present invention relates to a composition comprising the following components (A), (B), (C), (D), (E), and (F): (A) a silicone oil having an alkyl group having 8 to 28 carbon atoms added thereto; (B) a film-forming agent; (C) Ester oil that is liquid at 25°C, (D) an organic ultraviolet absorber that is solid at 25°C; (E) a lipophilic nonionic surfactant, (F)Water The present invention relates to a water-in-oil emulsion composition containing [Effects of the Invention]

[0007] The water-in-oil emulsion composition of the present invention has a high UV protection effect, and is excellent in long-lasting cosmetic effect, ability to conform to skin movement, and pore blurring effect.
