(Patent Document 1) Japanese Patent Publication No. 2019-99468

The present invention relates to a water-in-oil emulsion cosmetic, which contains the following components (A), (B), (C) and (D): (A) non-volatile silicone oil incompatible with squalane: 0.1~25% by mass (B) silicone film-forming agent: 2~20% by mass (C) volatile oil (D) ester oil: 0.1~12% by mass wherein, the viscosity of component (A) at 25°C is 30~100000 mPa・s; the mass ratio of component (A) to the total content of components (A) and (D) is (A)/[(A)+(D)] 0.3~0.95.

The inventors of the present invention have found that an emulsified cosmetic containing a silicone film-forming agent, a volatile oil, and an ester oil has excellent makeup lasting property, but has the problem of easy makeup removal over time.

The inventors of the present invention have found that by using specific non-volatile silicone oil and ester oil in a specific ratio in an oil-in-water emulsion cosmetic containing a silicone film-forming agent and a volatile oil, the skin brightness immediately after application can be maintained, a uniform makeup finish can be obtained, and even after a long period of time, there will be no oily shine, makeup fading can be suppressed, and the makeup feel can be sustained.

The characteristics of the water-in-oil emulsion cosmetic of the present invention are: excellent makeup feeling lasting, and even after a long time, the skin brightness and uniform makeup feeling just after application can be maintained, and the oily shine caused by sebum can be suppressed, and the makeup will not be removed even if it comes into contact with the towel-made skin. Here, the so-called "makeup feeling" refers to a natural makeup feeling with sufficient coverage and a sense of transparency.

The component (A) used in the present invention is a non-volatile silicone oil that is incompatible with squalane. The so-called "non-volatile" means that when 1g of the oil is spread in a glass culture dish with a diameter of 48mm and placed at 25°C and normal pressure for 24 hours, the mass reduction rate is less than 1%. In addition to linear silicone oils such as dimethyl polysiloxane, silicone oils can also be modified silicones with substituents such as phenyl modified polysiloxane and methyl hydropolysiloxane. Furthermore, the so-called "incompatible with squalane" means that the silicone oil and squalane are mixed in a mass ratio of 1:1, held in the hand, and stirred for 30 seconds at a shaking frequency of 120 times/minute and a shaking amplitude of 30cm, and then stirred for another 30 seconds using a vortex mixer, and then left to stand for 1 minute. When observing this state, it is white and cloudy. This kind of silicone oil will separate into two layers over time.

Ingredient (A) is incompatible with squalane, so that the makeup feels lasting, and even after the passage of time, the skin brightness immediately after application will continue, and a smooth and even finish can be obtained. It is preferred that it contains at least dimethyl polysiloxane.

[Examples 1 to 10, Comparative Examples 1 to 3] An oil-in-water emulsion cosmetic of the composition shown in Table 1 was prepared and applied to the skin. The degree of oiliness caused by sebum, the degree of secondary adhesion to a towel, the brightness of the skin, and the uniformity of the skin were evaluated after 8 hours. The results are summarized in Table 1. In addition, the dimethyl polysiloxane used in the example was mixed with squalane at a mass ratio of 1:1, and the mixture was mixed in the hand at a shaking frequency of 120 times/min and a shaking amplitude of 30 cm for 30 seconds, and then further stirred for 30 seconds using a vortex mixer. The state (whether it is compatible with squalane) when it was left to stand for 1 minute is shown in Table 2.

(Manufacturing method) The powder phase components are mixed and crushed, added to the separately mixed oil phase components, and dispersed using a disperser. Then, the water phase components are added, dispersed using a disperser, and then stirred using a homogenizer to obtain an oil-in-water emulsified cosmetic (foundation).

(Evaluation method) (1) Degree of oiliness caused by sebum after 8 hours of application: Five professional sensory inspectors applied each foundation to the skin and evaluated the degree of oiliness caused by sebum after 8 hours according to the following criteria. The result is a total score of 5 points. 5: No oiliness caused by sebum at all. 4: No oiliness caused by sebum. 3: Not much oiliness caused by sebum. 2: Slight oiliness caused by sebum. 1: Oiliness caused by sebum.

(2) Secondary adhesion to a towel after 8 hours of application: Five professional sensory inspectors applied each foundation to the skin and conducted sensory evaluations based on the following criteria for the degree of foundation color transfer when a cotton towel was pressed against the skin 8 hours after application. The result was the total score of the five digits. 5: Even when the towel was pressed against the skin after application, there was no foundation adhesion at all. 4: Even when the towel was pressed against the skin after application, there was no foundation adhesion. 3: Even when the towel was pressed against the skin after application, there was little foundation adhesion. 2: When the towel was pressed against the skin after application, there was a slight amount of foundation adhesion. 1: When the towel is pressed against the skin after application, the foundation adheres.

(3) Skin brightness after 8 hours of application: Five professional sensory inspectors applied each foundation to the skin and evaluated the brightness of the makeup skin 8 hours later according to the following criteria. The result is the total score of the five digits. 5: The makeup skin looks brighter. 4: The makeup skin looks slightly brighter. 3: The makeup skin does not look too bright. 2: The makeup skin does not look brighter. 1: The makeup skin does not look brighter at all.

(4) Skin evenness after 8 hours of application: Five professional sensory inspectors applied each foundation to the skin and evaluated the evenness of the makeup on the skin 8 hours after application according to the following criteria. The result is the total score of the five inspectors. 5: The makeup on the skin looks even. 4: The makeup on the skin looks slightly even. 3: The makeup on the skin looks not very even. 2: The makeup on the skin looks uneven. 1: The makeup on the skin looks completely uneven.
