Description

Description: TECHNICAL FIELD The present invention relates to a makeup cosmetic having a film form, and more particularly to a makeup cosmetic having good portability and storage stability.

[Conventional technology]

Conventionally, makeup cosmetics have generally been mixed and / or molded with various pigments, oily components and the like, and filled in containers such as compacts, bottles and tubes.

Recently, a sheet-shaped makeup cosmetic having a makeup cosmetic composition adhered to a mount has been developed because of portability, suitability for small amount use, and the like. For example, a fluorocarbon and a makeup cosmetic composition are adhered to a mount, and then the fluorocarbon is volatilized (Japanese Patent Application Laid-Open No.
No. 63-132815), a slurry obtained by mixing powder, organic bentonite and / or ethylcellulose, and a volatile solvent is sprayed on a mount, and then dried to form a thin film powder cosmetic on the mount. What has adhered (Japanese Unexamined Patent Publication No. 63-139109)
No.) is known.

[Problems to be solved by the invention]

However, these conventional makeup cosmetics,
In the form of compact, bottle, tube, etc., it is inferior in portability, in emulsified cosmetics, inferior in storage stability, in powdered metal plate, inferior in impact resistance, and in the above-mentioned sheet-shaped cosmetics. It has not yet been fully satisfactory, as has always been inferior in character and feel.

[Means for solving the problem]

The present inventor has conducted various studies to solve such problems, and as a result, a makeup cosmetic made by forming a composition comprising pullulan, a pigment and an oily component into a film has been developed to be portable, storage-stable, impact-resistant, and used. The present invention was found to be excellent in properties and feel, and completed the present invention.

That is, the present invention relates to (a) 8 to 30% by weight of pullulan,
The present invention provides a film-shaped makeup cosmetic having a thickness of 0.01 to 1 mm, comprising (b) 1 to 60% by weight of a pigment and (c) 1 to 50% by weight of an oily component.

Pullulan (a) used in the makeup cosmetic of the present invention is a neutral glucan containing glucose as a minimum unit and is a water-soluble polysaccharide, and maltotriose is α-1,
It has a linear structure repeated with six bonds. Pullulan
It quickly dissolves in both cold water and hot water, does not gel, and becomes a transparent and viscous neutral aqueous solution. A colorless and transparent film is formed by film formation.

The amount of pullulan (a) incorporated into the makeup cosmetic of the present invention is 8 to 30% by weight in the final film state. 8
When the amount is less than the weight%, a film having good gloss and strength cannot be obtained. On the other hand, if it exceeds 30% by weight, the re-solubility in water is poor and the usability is poor.

The pigment (b) used in the present invention is not particularly limited, and may be any of inorganic or organic pigments generally used in makeup cosmetics. Examples of the inorganic pigment include talc, titanium oxide, kaolin, mica, silicic acid, iron oxide, zinc oxide, titanium oxide mica, ultramarine, bentonite, and the like. As organic pigments, polyethylene,
Nylon, crystalline cellulose, starch, Teflon, tar dye, and the like. In addition, oil-based pigments, collagen-treated pigments and other treated pigments, and titanium-treated nylon and titanium-treated mica and other composite pigments can also be used.

The amount of the pigment (b) is 1 to 60% by weight. 1% by weight
If it is less than the above, the effect as a makeup cosmetic is not exhibited.
If it exceeds 60% by weight, the strength of the formed film is reduced.

The oil component (c) used in the present invention is not particularly limited as long as it is usually used in cosmetics. Hydrocarbons such as, for example, liquid paraffin, squalane, petrolatum;
Natural oils such as castor oil and jojoba oil; animal oils such as mink oil and lanolin; ester oils such as isopropyl myristate and glyceryl trioctanoate; silicone oils such as methylpolysiloxane and methylphenylpolysiloxane; isostearic acid and oleic acid Higher fatty acids;
Higher alcohols such as oleyl alcohol and isostearyl alcohol can be used.

The compounding amount of the oil component (c) is 1 to 50% by weight. If it is less than 1% by weight, the effect of blending the oily component will not be exhibited. If it exceeds 50% by weight, wetting of the film by the oily component will proceed, resulting in poor film strength and sticky handling.

The makeup cosmetic of the present invention may contain a film-forming water-soluble polymer other than pullulan. Examples of such a water-soluble polymer include carrageenan, gum arabic, alginates, arabinogalactan, xanthan gum, scallog, dextran, gelatin, casein, carboxymethylcellulose, polyvinyl alcohol, polyvinyl pyrrolidone, and the like. These water-soluble polymers are suitable for adjusting the re-solubility in water of the film-shaped makeup cosmetic of the present invention and for adjusting the film strength, and are preferably blended in an amount of 0.5 times by weight or less with respect to pullulan.

The cosmetic of the present invention may contain a polyhydric alcohol as a pigment dispersion medium or humectant. Examples of polyhydric alcohols include glycerin, propylene glycol, 1,3-butylene glycol and the like.

Furthermore, the makeup cosmetics of the present invention include other humectants, fragrances, preservatives, surfactants, beautiful skin ingredients, medicinal ingredients,
Dyes, ultraviolet absorbers, antioxidants and the like can be blended within a range that does not impair the effects of the present invention.

The makeup cosmetic of the present invention can be produced, for example, by any of the following methods.

Method of dispersing oily component Water is added to pullulan (a), pigment (b) and oily component (c) and uniformly mixed to obtain a paste, which is formed into a film and dried to make a film-shaped makeup. Get the fee.

Here, as a means for mixing and dispersing the oil component (c), use of a surfactant, mechanical dispersion and the like can be mentioned.

Oil component impregnation method Water is added to pullulan (a) and pigment (b) and uniformly mixed to obtain a paste, which is formed into a film and dried, and then impregnated with oil component (c). Then, a film-shaped makeup cosmetic is obtained.

Here, the film is impregnated with the oily component by spraying and applying the oily component to the film. The oily component may be dissolved by heating or diluted with a volatile solvent.

In any of the above methods, any known film forming method may be adopted as the film forming method.For example, a paste-like material is cast on a flat plate such as a glass plate, a plastic plate, and a metal plate, and molded. It may be dried. In preparing the paste, a lower alcohol may be used in combination with water.

The thickness of the film-shaped makeup cosmetic of the present invention is 0.01
