In this way, a cleansing cosmetic with excellent cleansing effect (makeup dirt removal effect) and an emollient feeling (no dry feeling) to the skin after cleansing has not been obtained yet, and development is desired.

Accordingly, an object of the present invention is to provide a cleansing cosmetic that is excellent in a cleansing effect and has an emollient feeling (no dry feeling) to the skin after cleansing, while having suppressed slipperiness and stickiness. Another object of the present invention is to provide a sheet cosmetic in which the cleansing cosmetic is impregnated into a sheet base material.

MEANS TO SOLVE THE PROBLEM As a result of earnestly examining this inventor in order to achieve the said objective, according to the emulsified cleansing cosmetic containing a specific silicone oil, highly volatile hydrocarbon oil, a specific emulsifier, and water, it is excellent in a cleansing effect, and at the same time, it is excellent in the skin after cleansing. It was found that, while imparting an emollient feeling (no feeling of dryness), slipperiness and stickiness were suppressed. The present invention has been completed based on these findings.

That is, the present invention is an emulsified cleansing cosmetic comprising the following component (A1), the following component (A2), the following component (B), the following component (C), and the following component (D).

Component (A1): at least one silicone oil selected from the group consisting of cyclic silicone and dimethylpolysiloxane having a kinematic viscosity at 25°C of 0.5 to 3 mm 2 /s

Component (A2): at least one silicone oil selected from the group consisting of caprylyl methicone and dimethylpolysiloxane having a kinematic viscosity of 5 to 10 mm 2 /s at 25°C

Component (B): hydrocarbon oil having a flash point of 35 to 110°C

Component (C): nonionic surfactant and/or polymer emulsifier

The sheet cosmetic of the present invention is excellent in a cleansing effect simply by wiping it on the skin, and while imparting an emollient feeling (no dry feeling) to the skin after cleansing, slipperiness and stickiness can be suppressed. It is preferable to use it as a wiping-off sheet cosmetic (for example, a cleansing sheet).

The emulsified cleansing cosmetic of the present invention contains a highly volatile silicone oil (component (A1) above) and a hydrocarbon oil of high volatility (component (B) above) selected from cyclic silicone and dimethylpolysiloxane having a small kinematic viscosity. have an effect In particular, it has an excellent cleansing effect on any type of makeup cosmetics of a type containing silicone oil and a type containing a hydrocarbon compound.

However, when only the highly volatile oil as described above is used as the oil component, there is a problem in that excessive degreasing occurs after wiping, resulting in a strong feeling of dryness (coarseness). On the other hand, in the emulsified cleansing cosmetic of the present invention, the component (A1) or the component (A1) or the component ( Even after volatilization of B), the said component (A2) was made to remain|survive to some extent, and it succeeded in suppressing dry feeling. In addition, since the component (A2) has a volatilization rate that is not too slow, it also suppressed the occurrence of slippery and stickiness due to the residual oily component, and while imparting a moisturizing feeling, a light feeling of use with suppressed shine was achieved.

Furthermore, by containing the said component (C) which is an emulsifier, it can be set as a shiny oil-in-water emulsified cleansing cosmetic. Among them, in the case where a polymer emulsifier (component (c2)) is used as the component (C) (more preferably, when the component (c1) and the component (c2) are used in combination), emulsified particles of oil can be stably controlled to an appropriate size, and oil content can be released by application of pressure, thereby forming an emulsifying system that exhibits a more effective cleansing effect. Thereby, although the emulsion cleansing cosmetic of this invention is a shiny oil-in-water type emulsion cleansing cosmetic, it has a high cleansing effect similar to oil cleansing.
