Description

Technical Field

[0001] The present invention relates to an emulsified composition. Background Art

[0002] In order to cover pores, makeup cosmetics such as foundation must firmly adhere to the skin.

[0003] For example, Patent Document 1 describes an oil-in-water emulsified cosmetic containing a composite powder composed of particles in which silicone particles are coated with a polysiloxane resin, and a non-volatile oil agent other than silicone oil, which can make the skin look bright, and has excellent stretchability and adhesion, and can exhibit a pore concealing effect.

[0004] On the other hand, sunscreen cosmetics formulated with carbonates are known.

[0005] For example, Patent Document 2 describes a sunscreen cosmetic formulated with an inorganic ultraviolet scattering agent composed of hydrophobic fine particle metal oxides, tubular basic magnesium carbonate, and an oil agent. Patent Document 3 describes a cosmetic composition having a function of protecting against UV-A and / or UV-B, which contains at least one inorganic ultraviolet filtering component (UV filter) and surface-reacted calcium carbonate.

[0006] These cosmetics improve the ultraviolet protection effect by using carbonates.

[0009] (Patent Document 3) Japanese Patent Application Laid-Open No. 2020-506953 Summary of the Invention

[0010] The present invention relates to an emulsified composition containing the following components (A), (B), (C), (D) and (E):

[0011] (A) Lipophilic nonionic surfactant

[0012] (B) Film-forming agent

[0013] (C) Non-volatile oil that is liquid at 25°C

[0014] (D) Carbonate

[0015] (E) Water Detailed Description of the Invention

[0016] Existing emulsified cosmetics tend to have a sense of surface slippage of the cosmetics on the skin when applied, resulting in insufficient actual feeling of the cosmetics fully adhering to the skin. Moreover, the adhesion of the cosmetics to pores is also weak, and pores cannot be fully covered. In addition, there is also the problem of residual stickiness on the skin after application.

[0017] The inventors of the present invention found that: by using a lipophilic nonionic surfactant, a film-forming agent, a non-volatile oil in a liquid state at 25 °C, and a carbonate in combination, an emulsified composition capable of solving the above problems can be obtained.

[0018] The emulsified composition of the present invention has a reduced surface slippage when applied, improves the close contact feeling with the skin after application, and can fully cover pores. Further, it can reduce the stickiness of the skin after application.

[0019] In addition, the so-called "surface slippage" means that when an emulsified cosmetic is taken with a finger or the like and applied to the face, it is felt that it spreads infinitely on the skin like a spreading liquid oil, without showing the actual feeling of the emulsified cosmetic adhering to the skin while spreading. In addition, the so-called "close contact feeling" means that the emulsified composition adhering to the skin after application can still follow the skin movement without falling off from the skin surface even when the facial skin moves due to facial expression changes or the like, and does not partially concentrate in large wrinkles or small wrinkles in a biased manner, and adheres firmly.

[0020] Regarding the lipophilic nonionic surfactant of component (A) used in the present invention, from the viewpoints of reducing the surface slippage of the emulsified composition on the skin during application, improving the close contact feeling after application, and obtaining a stable emulsified composition, the HLB is preferably 1 to 8, more preferably 2 to 7, and further preferably 3 to 6.

[0021] Here, HLB [Hydrophilic-Lipophilic Balance value] refers to the value of the molecular weight of the hydrophilic group part in the total molecular weight of the surfactant, and this value is obtained by the Griffin formula. In addition, when it is composed of two or more nonionic surfactants, the HLB of the mixed surfactant is obtained as follows. The HLB of the mixed surfactant is the value obtained by arithmetically averaging the HLB values of the respective nonionic surfactants according to their blending ratios.

[0022] Mixed HLB = Σ(HLBx × Wx) / ΣWx

[0023] HLBx represents the HLB value of nonionic surfactant X.

[0240] [Examples]

[0241] [Examples 1 to 12 and Comparative Example 1]

[0242] Prepare a water-in-oil emulsion cosmetic having the composition shown in Tables 1 and 2, and evaluate it in terms of the degree of no surface slipperiness during application, the skin adhesion after application, the pore coverage, and the degree of non-greasiness of the skin after application. The results are combined and shown in Tables 1 and 2.

[0243] (Manufacturing method)

[0244] Heat and stir the components (A), (B), (C) and other oily components at 80 °C to prepare an oil phase mixture. Add the pre-ground and mixed powder phase to the oil phase mixture and mix using a homogenizing mixer. Then, add the water phase heated to 80 °C, and after mixing, cool to room temperature to obtain a water-in-oil emulsion cosmetic.

[0245] (Evaluation method)

[0246] (1) Degree of no surface slipperiness during application

[0247] Three professional reviewers each take 0.3 g of each water-in-oil emulsion cosmetic with their fingers and evaluate the degree of no surface slipperiness during application to the face according to the following criteria. The results are the total scores of the three professional reviewers.

[0248] In addition, "surface slipperiness" means that when taking a water-in-oil emulsion cosmetic with a finger and applying it to the face, it is felt that it spreads infinitely on the skin like a spreading liquid oil, and the actual feeling of the water-in-oil emulsion cosmetic adhering to the skin and spreading at the same time is not presented.

[0249] 5: Clearly feel no surface slipperiness.

[0250] 4: Almost no surface slipperiness is felt.

[0251] 3: Slightly feel surface slipperiness.

[0252] 2: Slightly feel surface slipperiness.

[0253] 1: Clearly feel surface slipperiness.

[0254] (2) Skin adhesion after application

[0255] After three professional reviewers each take 0.3 g of each water-in-oil emulsion cosmetic with their fingers, apply it to the face and spread it, evaluate the skin adhesion after application according to the following criteria. The results are the total scores of the three professional reviewers.

[0256] Furthermore, the term "closely adhering feeling" means that the water-in-oil emulsion composition adheres to the skin after application and follows the movement of the skin without coming off the skin surface, even when the facial skin moves due to changes in facial expression, etc. Furthermore, the composition adheres firmly without being concentrated in certain areas, such as large or small wrinkles.

[0257] 5: The sense of close contact is clearly felt.

[0258] 4: There is a strong sense of close contact.

[0259] 3: Feel the close contact.

[0260] 2: I don’t feel much close contact.

[0261] 1: There is no obvious sense of close contact.

[0262] (3) Pore covering power

[0263] Three professional panelists took 0.3g of each water-in-oil emulsion and spread it across their face. The panelists then evaluated the pore coverage using the following criteria. The results were calculated using the total score from the panelists.

[0264] 5: Feel that the pores are obviously hidden.

[0265] 4: It feels like the pores are hidden.

[0266] 3: Feel that pores are slightly concealed.

[0267] 2: It feels like the pores are not well hidden.

[0268] 1: It feels like pores are visibly not hidden.

[0269] (4) The skin does not feel sticky after application

[0270] Three professional panelists took 0.3g of each water-in-oil emulsion and applied it to their face. They then touched the skin and evaluated the lack of stickiness based on the following criteria. The results were calculated using the combined scores of the three panelists.

[0271] 5: There is no obvious feeling of stickiness.

[0272] 4: Almost no stickiness.

[0273] 3: Doesn’t feel sticky.

[0274] 2: Slightly sticky.

[0275] 1: It feels noticeably sticky.
