Description

Technical Field

[0001] The present invention relates to an emulsion composition.

Background Art

[0002] In makeup cosmetics such as foundation, in order to cover pores, it is necessary to firmly attach the cosmetics to the skin. For example, Patent Document 1 describes an oil-in-water emulsion cosmetic containing a composite powder composed of particles in which the surface of silicone rubber particles is coated with a silicone resin, and a non-volatile oil agent other than silicone oil, which makes the skin look bright, has excellent stretchability and adhesion, and exhibits a pore concealing effect. On the other hand, sunscreen cosmetics containing carbonate are known. For example, Patent Document 2 describes a sunscreen cosmetic containing an inorganic ultraviolet scattering agent composed of hydrophobic fine particle metal oxide, tubular basic magnesium carbonate and an oil component, and Patent Document 3 describes a cosmetic composition having UV-A and / or UV-B protection containing at least one inorganic UV filter and surface-reacted calcium carbonate. In these cosmetics, the use of carbonate improves the ultraviolet protection effect.

Summary of the Invention

Problems to be Solved by the Invention

[0004] It should be noted that in the original text, the number of Patent Document 3 in the English translation should be "Japanese Patent Application Laid-Open No. Hei 11-252611" according to the content you provided. If there is an error in the original text, please correct it in time.In conventional emulsified cosmetics, when applied, the cosmetics tend to have a slippery feeling on the skin, lacking a sense of sufficient adhesion to the skin. Also, the adhesion of the cosmetics to pores is weak, and pores cannot be sufficiently covered. Moreover, there was also a problem that a sticky feeling remained on the skin after application.

Means for Solving the Problems

[0005] The present inventor has found that an emulsified composition that solves the above problems can be obtained by using a combination of a lipophilic nonionic surfactant, a film-forming agent, a nonvolatile oil that is liquid at 25°C, and a carbonate.

[0006] The present invention relates to an emulsified composition containing the following components (A), (B), (C), (D) and (E): (A) Lipophilic nonionic surfactant, (B) Film-forming agent, (C) Nonvolatile oil that is liquid at 25°C, (D) Carbonate, (E) Water It relates to an emulsified composition containing them.

Effects of the Invention

[0007] The emulsified composition of the present invention has a reduced slippery feeling during application, improves the adhesion to the skin after application, can sufficiently cover pores, and moreover, reduces the sticky feeling of the skin after application. Note that the slippery feeling means that when an emulsified cosmetic is taken on a fingertip or the like and applied to the face, it feels as if a liquid oil agent is being stretched and spreads indefinitely on the skin, indicating that there is no feeling of the emulsified cosmetic stretching while adhering to the skin. Also, the adhesion means that the emulsified composition attached to the skin after application does not come off from the surface of the skin while following the movement of the facial skin even when changing expressions or the like, and does not partially gather due to large wrinkles or small wrinkles, indicating that it adheres firmly.

Modes for Carrying Out the Invention

[Examples]

[0111] Examples 1-12 and Comparative Example 1 Water-in-oil emulsion cosmetics with the compositions shown in Tables 1 and 2 were prepared, and their smoothness upon application, adherence to the skin after application, pore coverage, and lack of stickiness after application were evaluated. The results are also shown in Tables 1 and 2.

[0112] (Manufacturing method) Components (A), (B), (C) and other oily components were heated and stirred at 80°C to prepare an oil phase mixture. A pre-ground powder phase was added to the oil phase mixture and mixed using a homomixer. Then, an aqueous phase heated at 80°C was added and mixed, and the mixture was cooled to room temperature to obtain a water-in-oil emulsion cosmetic.

[0113] (Evaluation method) (1) Lack of slipperiness during application: Three expert evaluators applied 0.3g of each water-in-oil emulsion cosmetic to their faces using their fingers, and evaluated the lack of slipperiness during application according to the following criteria. The results are shown as the total score from the three expert evaluators. Furthermore, a "superficial feeling" refers to the sensation that when a water-in-oil emulsion cosmetic is taken on the fingertips and applied to the face, it feels like a liquid oil is being spread, continuing to spread on the skin indefinitely, without the feeling that the water-in-oil emulsion cosmetic is adhering to and spreading the skin. 5; I feel there is clearly no feeling of superficiality. 4; I feel there is almost no slipperiness. 3; I feel there isn't much of a slippery feeling. 2; I feel there's a slight slipperiness to it. 1; I definitely feel there's a superficiality to it.

[0114] (2) How well the product adheres to the skin after application: Three expert evaluators took 0.3g of each water-in-oil emulsion cosmetic on their fingers, applied it to their faces, and spread it. They then evaluated the adherence to the skin after application according to the following criteria. The results are shown as the total score from the three expert evaluators. Furthermore, "adhesion" refers to the fact that, after application, the water-in-oil emulsion composition adheres firmly to the skin, following the movement of the skin even when the face is moved, such as when changing facial expressions, without coming off the skin's surface, and without gathering in areas such as large or small wrinkles. 5; I definitely feel a sense of closeness. 4; I feel a very snug fit. 3; I feel a sense of closeness. 2; I don't feel much of a snug fit. 1; I feel there is clearly no sense of closeness.

[0115] (3) Pore coverage: Three expert evaluators took 0.3g of each water-in-oil emulsion cosmetic on their fingers, applied it to their faces, and spread it. They then evaluated its pore coverage according to the following criteria. The results are shown as the total score from the three expert evaluators. 5; I feel that my pores are clearly hidden. 4. I feel like my pores are hidden. 3; I feel like my pores are almost completely hidden. 2. I feel that it doesn't cover my pores very well. 1. I feel that my pores are not clearly hidden.

[0116] (4) No stickiness on the skin after application: Three expert evaluators took 0.3g of each water-in-oil emulsion cosmetic on their fingers, applied it to their faces, and then touched their skin after application to evaluate the lack of stickiness according to the following criteria. The results are shown as the total score from the three expert evaluators. 5; I notice a clear lack of stickiness. 4; I feel it's hardly sticky at all. 3; I feel it's not very sticky. 2; I feel it's slightly sticky. 1; I feel that it is noticeably sticky.
