Description

Emulsified cleansing cosmetics {EMULSIFIED MAKEUP REMOVER}

The present invention relates to an emulsified cleansing cosmetic.

There are two types of cleansing cosmetics for the purpose of removing makeup: a type that is washed off and used, and a type that is soaked in cotton and then wiped off. In the latter case, since the cosmetic composition remains on the skin after wiping, it is important that the skin feel after wiping is good.

For example, Patent Document 1 (Example) discloses a cleansing cosmetic comprising liquid paraffin and cyclic silicone as main oily components. In addition, Patent Document 2 (Example) discloses a cleansing cosmetic comprising a highly volatile hydrocarbon oil and cyclic silicone as main oily components.

Japanese Unexamined Patent Publication No. 2001-302450 Japanese Unexamined Patent Publication No. 2005-239561

Both of the cleansing cosmetics described in Patent Documents 1 and 2 can exhibit high cleansing power. However, since the cleansing cosmetic of Patent Literature 1 mainly uses liquid paraffin, which is a hydrocarbon with low volatility as an oil component, after wiping off, there were cases where slipperiness or stickiness occurred. In addition, since the cleansing cosmetic of Patent Document 2 uses only an oil having high volatility as an oil, it is excessively degreased after wiping, and a strong feeling of drying occurred in some cases. As described above, a cleansing cosmetic having excellent cleansing effect (make-up dirt removal effect) and imparting an emollient feeling (no dryness) to the skin after cleansing has not yet been obtained, and development is desired.

Accordingly, it is an object of the present invention to provide a cleansing cosmetic in which smoothness and stickiness are suppressed while having excellent cleansing effect and imparting an emollient feeling (no dryness) to the skin after cleansing. Another object of the present invention is to provide a sheet cosmetic material obtained by impregnating a sheet base material with the cleansing cosmetic material.

The inventors of the present invention have studied intensively in order to achieve the above object. As a result, according to an emulsified cleansing cosmetic containing a specific silicone oil, a highly volatile hydrocarbon oil, a specific emulsifier, and water, it is excellent in cleansing effect, and at the same time, it is applied to skin after cleansing. While providing an emollient feeling (no dryness), we found that slipperiness and stickiness were suppressed. The present invention was accomplished 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 caprylylmethicone and dimethylpolysiloxane having a kinematic viscosity at 25°C of 5 to 10 mm 2 /s

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

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

Ingredient (D): water

It is preferable that the said emulsified cleansing cosmetic further contains the following component (E).

Ingredient (E): polyhydric alcohol

It is preferable that the said emulsified cleansing cosmetic is for wiping off.

The present invention also provides a sheet cosmetic material comprising a sheet base material and the emulsified cleansing cosmetic material impregnated with the sheet base material.

According to the emulsified cleansing cosmetic of the present invention, while excellent cleansing effect and imparting an emollient feeling (no dryness) to the skin after cleansing, slipperiness and stickiness are suppressed. For this reason, since cleansing can be performed without washing off by wiping, makeup removal can be performed easily in a short time. Further, by impregnating a sheet substrate with the emulsified cleansing cosmetic of the present invention to obtain a sheet cosmetic, a sheet cosmetic having the effect of the emulsified cleansing cosmetic of the present invention is obtained.

The sheet cosmetic of the present invention is excellent in cleansing effect by simply wiping the skin on the skin, and while imparting an emollient sensation (no dryness) to the skin after cleansing, it is possible to suppress slipperiness or stickiness. It is preferable to use a wipe-off sheet cosmetic (for example, a cleansing sheet) to be used.

The emulsified cleansing cosmetic of the present invention contains a highly volatile silicone oil (component (A1)) and a highly volatile hydrocarbon oil (component (B)) selected from cyclic silicone and dimethylpolysiloxane having a small kinematic viscosity, thereby providing excellent cleansing. Has an effect. In particular, it has an excellent cleansing effect for both types of makeup cosmetics, silicone oil-containing type and hydrocarbon compound-containing type.

However, in the case of using only the oil having high volatility as described above, there is a problem that excessive degreasing occurs after wiping, resulting in a strong feeling of dryness (coarse). In contrast, in the emulsified cleansing cosmetic of the present invention, the component (A1) or the component (A2), which is a silicone oil having a volatilization rate somewhat slower than that of the component (A1) or the component (B), is used in combination. Even after the volatilization of B), it succeeded in suppressing the dry feeling by making the said component (A2) remain to some extent. In addition, since the above-described component (A2) has a volatilization rate not too slow, it also suppresses the occurrence of slipperiness or stickiness due to the remainder of the oily component, imparts a moisturizing feeling, and achieves a light feeling of use with suppressed glossiness.

Moreover, by containing the said component (C) which is an emulsifying agent, it can be set as an oil-in-water type emulsified cleansing cosmetic that shines. Especially, when using a polymer emulsifier (the component (c2)) as the component (C) (more preferably, when the component (c1) and the component (c2) are used in combination), the emulsified particles of oil It is possible to form an emulsifying system stably controlling the oil to a suitable size, releasing oil by applying pressure, and exhibiting a more effective cleansing effect. Thereby, the emulsified cleansing cosmetic of the present invention has a high cleansing effect such as oil cleansing, although it is a shiny oil-in-water type emulsified cleansing cosmetic.
