Description

  The present invention relates to a sheet-like cosmetic that can effectively wipe off sweat and sebum, suppress stickiness, and provide more effective dry feeling to the skin, and a method for producing the same.

  Conventionally, dry type products such as mini towels, handkerchiefs and oil blotting paper, as well as wet type products such as wet tissue and sweat wipe sheets, have been put on the market as means for wiping the body's sebum and sweat. These products are impregnated into a sheet-like base material with powder, refreshing agent, disinfectant, wetting agent, fragrance, etc., and wipe off sweat and sebum on the skin to give a refreshing feeling and smell of sweat. It is used for the purpose of suppressing (see Patent Documents 1 to 3).

  However, although conventional products have effects such as cleansing the skin, giving a refreshing feeling, and suppressing the smell of sweat, the skin is often whitened or sticky.

(Sheet cosmetic)
The sheet-like cosmetic of the present invention is obtained by attaching an emulsified composition to a sheet-like base material, and further having other layers as necessary.
The emulsified composition contains silicone, a silicone derivative having a solubility parameter with a difference in solubility parameter of 1 or less, and a swellable clay mineral. In addition to the silicone, the silicone derivative, and the swellable clay mineral, And water-insoluble powder, and further contains other components as required.

-Silicone and silicone derivatives-
The silicone used in the present invention is not particularly limited and may be appropriately selected depending on the intended purpose. Examples thereof include dimethyl silicone oil such as methylpolysiloxane (SH-200 series manufactured by Toray Dow Corning Silicone Co., Ltd. as a commercial product). , Shin-Etsu Silicone KF series), Cyclic silicone oils such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane (commercially available SH series made by Toray Dow Corning Silicone, KF made by Shin-Etsu Silicone) Series), methylphenyl silicone oils such as methylphenylpolysiloxane (SH series manufactured by Toray Dow Corning Silicone Co., Ltd.). Among these, dimethyl silicone oil having a viscosity at 25 ° C. of 1 to 1000 mm ² / s is preferable. If the viscosity is less than 1 mm ² / s, the silicone oil may not be slippery and may cause skin irritation. If the viscosity is higher than 1000 mm ² / s, stickiness may be felt. is there.

  The silicone derivative is not particularly limited as long as the difference in solubility parameter from the various silicones is 1 or less. For example, a polyoxyethylene / methylpolysiloxane copolymer (as a commercial product) SH series made by Toray Dow Corning Silicone, KF series made by Shin-Etsu Silicone), polyether-modified silicones such as dimethylsiloxane, methyl (polyoxyethylene) siloxane, methyl (polyoxypropylene) siloxane copolymer, etc. . Among these, a polyoxyethylene / methylpolysiloxane copolymer is particularly preferable in that the swelling property of the swellable viscosity mineral in any of the silicones can be enhanced.

  As a preferable combination of the silicone and the silicone derivative, a difference in solubility parameter with polyether-modified silicone-dimethylsilicone oil is 1 or less, and a difference in solubility parameter with polyether-modified silicone-cyclic silicone oil is 1 or less. It is desirable that the difference in solubility parameter between the polyether-modified silicone-methylphenyl silicone oil is 1 or less. When a silicone derivative having a solubility parameter difference exceeding 1 is used, adjusting the emulsion composition using a dispersion mixed with the swellable clay mineral makes the dispersion of the swellable clay mineral unfavorable. .

Here, the solubility parameter (SP value) means a value calculated by the following formula (1).
However, in said formula (1), M represents the molecular weight of a silicone or a silicone derivative. d represents the specific gravity of the silicone or silicone derivative. G represents an attractive constant of an atom or substituent in the molecule, and this attractive constant uses a value obtained by PASmall, J. Appl. Chem. 3, 71 (1953) small.

As a compounding quantity of the said silicone derivative, 0.01-20 mass% is preferable with respect to the emulsion composition whole quantity, and 0.01-5 mass% is more preferable. When the blending amount of the silicone derivative having the above characteristics is less than 0.1% by mass, stability over time may not be secured, and when it exceeds 20% by mass, it may adversely affect the feeling of use such as stickiness. It is not preferable.

Among these, Kunipia is particularly preferable in that it has excellent swellability.
These may be used individually by 1 type and may be used in combination of 2 or more type.
These swellable clay minerals exhibit adsorptivity, and when a water-insoluble powder is contained in the impregnating liquid composition, it is preferable for further enhancing the adsorption of the water-insoluble powder to the skin.
As a compounding quantity of the said swellable clay mineral, 0.01-20 mass% is preferable with respect to the emulsion composition whole quantity, and 0.05-5 mass% is more preferable. When the blending amount of the swellable clay mineral is less than 0.01% by mass, the effect on the emulsification performance is small and the stability over time may be deteriorated, and when it exceeds 20% by mass, the dispersibility is poor. This is not preferable.

What processed these powders with oils, such as silicone, can also be used.

As a compounding quantity of the said water-insoluble powder, 0.1-15 mass% is preferable with respect to the emulsion composition whole quantity, and 0.5-10 mass% is more preferable. When the blending amount of the water-insoluble powder is less than 0.1% by mass, the dry feeling due to the powder may not be expressed. When the blending amount exceeds 15% by mass, the powder in the emulsion composition may not be expressed. Dispersibility may deteriorate.
Among these water-insoluble powders, it is particularly preferable to use a water-insoluble powder having a water absorption amount of 1 ml / g or more, which quickly absorbs moisture remaining on the skin and quickly develops a smooth feeling. It becomes.

Here, the measurement of the water absorption amount was performed as follows with reference to the oil absorption amount of JIS K5101.

From the results of Examples 6 to 8, Reference Examples 1 to 5, 9 to 11 and Comparative Examples 1 to 3 shown in Tables 2 to 5, when producing an emulsion composition containing silicone and a swellable clay mineral, In advance, silicone and a silicone derivative having a difference in solubility parameter of 1 or less and a swellable clay mineral are mixed to prepare a dispersion in which the swellable clay mineral is dispersed in the silicone. Mix and disperse the ingredients to prepare an emulsified composition and impregnate the emulsified composition to cleanse the skin, provide a refreshing sensation, suppress sweat odor, and make the skin white. Thus, it was found that a sheet-like cosmetic material can be provided that does not leave a sticky feeling and provides a comfortable and smooth feeling. In addition, since this emulsion composition does not show separation of oil such as silicone in the upper layer portion and the clay mineral can be uniformly dispersed, aggregation of the swellable clay mineral can be surely prevented, and stability over time can be improved. It turned out to be excellent.
Furthermore, according to Examples 6 to 8 and Reference Examples 3 to 5 , it was found that the water-insoluble powder having a water absorption amount of 1 ml / g or more is further improved to further improve the smooth feeling after wiping.
On the other hand, Comparative Example 1 is a case where an emulsified composition was prepared without containing silicone, Comparative Example 2 was a case where an emulsified composition was prepared without containing a silicone derivative, and Comparative Example 3 was Since the difference in SP value between the silicone and the silicone derivative is more than 1, the skin is not whitened, but the sticky feeling remains and the sheet-like cosmetic is inferior to the dry feeling. In addition, it was found that an oily component such as silicone was separated in the upper layer part, the clay mineral was aggregated, and the emulsion composition was inferior in stability over time.
