Abstract

PROBLEM TO BE SOLVED: To obtain a gommage cosmetic easy to apply, tending to produce tailings when scraped, slight in load on the skin because of being scrapable with light force, and affording refreshing feeling after used by combining crystalline cellulose, a film-forming polymer and a polyhydric alcohol in specified formulations. SOLUTION: This gommage cosmetic is obtained by including (A) 5-30 wt.% of crystalline cellulose, (B) 0.5-10 wt.% of a film-forming polymer (pref. polyvinyl alcohol), and (C) 10-50 wt.% of a polyhydric alcohol (pref. polyethylene glycol) It is recommended that the cosmetic also contains, for example, a lower alcohol such as ethanol, oily ingredient such as liquid paraffin, powder such as talc, thickening agent such as carboxyvinyl polymer, keratolytic agent such as salicylic acid. The cosmetic is recommendedly used in the form of an emulsion such as liquid or gel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a gomage cosmetic. More specifically, the present invention relates to a gomage cosmetic which easily generates scum when rubbed off, can be rubbed off with a light force, has a small burden on the skin, and has a refreshing after-use feeling with no residual residue on the skin.

[0002]

2. Description of the Related Art Gomage cosmetics are liquid or creamy preparations that are applied thinly to the skin, left to dry for a few minutes, and then rubbed lightly with the skin to remove the applied cosmetics. Is a new type of cosmetic that can be scraped off.

[0003] This gomage cosmetic is excellent in the effect of removing old keratin on the skin surface, and the action of scraping off old keratin like an eraser scum realizes a great effect for the user and gives satisfaction to use. It is an extremely excellent cosmetic in terms of giving.

[0004] Conventionally, as a preparation of such a gomage cosmetic, a preparation using crystalline cellulose having a property of high compression moldability or using solid paraffin which is not easily adapted to the skin is known.

[0005]

However, for example, when crystalline cellulose is used, its compression moldability depends on the water content. There has been a problem that when dropped, sufficient debris does not occur.

[0006] Further, the preparation using solid paraffin has a drawback that a certain amount of solid paraffin remains on the skin surface even after rubbing, and the feeling after use is not refreshed.

[0007] In addition, the conventional gomage cosmetics all have a large load on the skin when they are scraped off, and have the disadvantage that when they are scraped off with a strong force, the skin becomes red or painful.

In view of the above viewpoints, the present inventors have conducted intensive studies to solve the problems of the conventional gomage cosmetics, and as a result, combined crystalline cellulose, a film-forming polymer, and a polyhydric alcohol in a specific amount. When blended, it is easy to apply, easy to generate scum when rubbed off, it can be rubbed off with a light force, less burden on the skin, and a gorgeous cosmetic with a fresh after-use feeling with no residual residue on the skin is obtained This led to the completion of the present invention.

[0009]

That is, the present invention comprises crystalline cellulose, a film-forming polymer and a polyhydric alcohol, and has a crystalline cellulose content of 5 to 30% by weight based on the total amount of the gomage cosmetic. The content of the film-forming polymer is 0.5 to 10% by weight, and the content of the polyhydric alcohol is 1
It is intended to provide a gomage cosmetic characterized by being 0 to 50% by weight.

[0010] The present invention also provides the aforementioned gomage cosmetic wherein the polyhydric alcohol is polyethylene glycol.

Furthermore, the present invention provides the above-mentioned gomage cosmetic, wherein the film-forming polymer is polyvinyl alcohol.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The crystalline cellulose used in the present invention is equivalent to crystalline cellulose described in official publications such as the standard for cosmetic raw materials, and there are several grades depending on the particle size distribution of powder and the surface treatment method. However, any grade can be used.

The content of the crystalline cellulose is 5 to 30% by weight based on the total amount of the gomage cosmetic. If the amount is less than 5% by weight, sufficient debris is not generated when rubbing off. If the amount is more than 30% by weight, the viscosity of the preparation becomes high, making it difficult to apply it uniformly to the skin. In any case, a satisfactory effect cannot be obtained.

The film-forming polymer used in the present invention includes:
There is no particular limitation as long as it is a polymer capable of forming a film, and for example, polyvinyl alcohol, polyvinylpyrrolidone, amphoteric methacrylate copolymer, sodium carboxymethylcellulose, hydroxyethylcellulose, methylcellulose and the like can be used. In the present invention, polyvinyl alcohol is particularly preferred.

The compounding amount of the film-forming polymer is 0.5 to 10% by weight based on the total amount of the gomage cosmetic. When the amount is less than 0.5% by weight, sufficient debris is not generated when rubbing off. When the amount is more than 10% by weight, the film strength after drying is too strong, and conversely, debris is hardly generated. In any case, a satisfactory effect cannot be obtained.

The polyhydric alcohol used in the present invention includes:
For example, glycerin, propylene glycol, 1,3-
Examples include butylene glycol, dipropylene glycol, polyethylene glycol, sorbitol, polyoxyethylene methyl glucoside, and polyoxypropylene diglyceryl ether. In the present invention, polyethylene glycol is particularly preferred.

The blending amount of the polyhydric alcohol is 10 to 50% by weight based on the total amount of the gomage cosmetic. The amount is 1
When the amount is less than 0% by weight, the residue is not dried sufficiently on the skin and does not generate sufficient residue when rubbed off. On the other hand, when the amount is more than 50% by weight, the residue remains in close contact with the skin even after drying. In any case, satisfactory effects cannot be obtained, for example, it hardly occurs.

The gomage cosmetic of the present invention can be produced according to a conventional method by blending, as necessary, components generally incorporated in cleaning products, cosmetics, and the like, in addition to the above essential components. it can. Ingredients include lower alcohols such as ethanol and isopropyl alcohol; oils such as liquid paraffin, higher alcohol, ester oil and methylpolysiloxane; powders such as talc, kaolin, titanium oxide and silicic anhydride; Thickeners such as xanthan gum, sodium alginate and bentonite; keratin softeners such as salicylic acid, urea, and sulfur; surfactants, preservatives, bactericides, ultraviolet absorbers, chelating agents, antioxidants, and fragrances.

The dosage form of the gomage cosmetic of the present invention is not particularly limited. For example, an emulsified gomage cosmetic is preferable.
For example, it is used as a liquid, gel, emulsion, or cream.

[0021]

As is clear from Examples 9 to 12 in Table 3, the gorgeous cosmetics of the present invention showed an easy-to-use scum when scraped off in either a semi-dry state or after being completely dried. Excellent usability with no stickiness or residue. When the blending amount of the film-forming polymer (polyvinyl alcohol) is less than 0.5% by weight (Comparative Example 5), it is difficult to produce debris in a semi-dried state, and there is much residue after gomage, and the feeling after use is not good. In addition, when the amount exceeds 10% by weight (Comparative Example 6), it is difficult to produce scum when completely dried, and the stickiness during coating or after drying is large, so that the feeling of use is not good. Did not give satisfactory results.
