Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like cosmetic composition which continuously suppresses stickiness and shine caused by excessive sebum and maintains a smooth skin feel.

[0002]

2. Description of the Related Art A thin oil film is formed on the surface of the epidermis of the skin, which prevents foreign substances from entering from the outside world, protects the skin from irritation of various substances, and suppresses water evaporation to prevent skin surface. It has the effect of lubricating. On the other hand, when sebum becomes excessive, it causes stickiness, shine, makeup loss, etc., and also causes seborrheic diseases such as acne. Therefore, a method of physiologically suppressing the secretion of sebum using a medicinal agent has been investigated, but an effective medicinal agent has not been found yet.

Further, as a method for removing excessively secreted sebum, various cosmetics containing oil-absorbing powder which physically adsorbs sebum have been proposed. However, with conventional cosmetics, stickiness and shine caused by sebum cannot be suppressed continuously, and it is difficult to maintain a smooth skin feel. For example, lotion type (mist type)
Since the cosmetics (1) have high fluidity and are easily scattered, they may stain clothes and the surroundings, and it is difficult to uniformly disperse and stabilize the powder. In addition, gel and cream type cosmetics contain a large amount of thickeners, etc., and are not satisfactory in terms of feeling such as stickiness.Furthermore, solid type cosmetics have a refreshing feeling of use. Could not be granted.

On the other hand, there has been proposed a cosmetic-impregnated sheet in which pulp, cotton or the like is used as a sheet base material and an aqueous medium containing powder is impregnated therein. However, since these use hydrophilic fibers such as pulp and cotton, the aqueous medium is absorbed and the transferability is poor. Also,
In the case of a wet papermaking method using pulp, although the surface is dense and the powder transfer efficiency is high, the porosity of the sheet base material is small and the impregnation ratio of the aqueous medium cannot be increased. Further, since the elasticity of the sheet base material is small, there is a problem that the transfer efficiency of the aqueous medium is poor. Furthermore, in the case of a cosmetic impregnated sheet obtained by impregnating a general non-woven fabric with an aqueous medium containing powder, the powder is easily carried inside the non-woven fabric, so the transfer efficiency to the skin is low and sufficient after wiping. Cannot give a comfortable feeling. In addition, since the non-woven fabric does not have sufficient elasticity, the transferability of the aqueous medium is poor.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet-like cosmetic composition which continuously suppresses stickiness and shine caused by excess sebum and maintains a smooth skin feel.

[0006]

Means for Solving the Problems The present inventors have found that a sheet-like cosmetic composition in which a sheet base material containing a hydrophobic fiber is impregnated with a specific gel-like lotion gives a refreshing feeling to the skin after application, It has been found that the powder efficiently remains on the skin, stickiness and shine caused by excess sebum are continuously suppressed, and a smooth skin feel is maintained.

The present invention contains the following components (a) to (d) and has a viscosity at 25 ° C. of 500 to 10,000 mPas.
The present invention provides a sheet cosmetic in which a gel lotion of s is impregnated into a sheet base material containing a hydrophobic fiber. (a) Oil absorbing powder having a squalane oil absorption of 1.0 g / g or more,
(b) Spherical powder other than (a), (c) alkyl-modified carboxyvinyl polymer, and (d) basic substance.

In the present invention, the viscosity is measured by the following method.

(Measurement of Viscosity) Approximately 45 g of gel-like lotion was placed in a 50-mL wide-mouth glass bottle and submerged in a water bath maintained at 25 ° C. so that the whole body except the lid of the bottle was submerged.
Held for hours. After 2 hours, the glass bottle was immediately pulled out from the water bath, set in a B-type viscometer (type BM, manufactured by Tokyo Keiki Co., Ltd.) equipped with a No. 3 rotor, and viscosity was measured at 6 rpm for 1 minute. Multiply the displayed value by the measurement condition multiplier (200) to obtain the viscosity at that temperature (mPa ·
