Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a gommage cosmetic composition, and more specifically, in a gommage cosmetic composition such as a gel or a cream, it has excellent storage stability with time, particularly storage stability at high temperature. The present invention relates to a gommage cosmetic composition in which it takes a short time for the residue to appear due to the gommage agent contained in the cosmetic composition and which is excellent in usability.

[0002]

2. Description of the Related Art Gommage cosmetics include a film formed on the skin by applying a physical external force such as massaging the cosmetics on the skin after applying the cosmetics on the skin. It is a cosmetics intended to remove old dead skin cells, dirt, etc. by scraping them off onto the cosmetics. A component for adsorbing and scraping off keratin and dirt and the like (gommage effect) is called a gommage agent, and conventionally, those using crystalline cellulose or solid paraffin have been proposed.

[0003]

However, in a gommage cosmetic composition containing a cellulose powder, the cellulose powder does not aggregate in the preparation and sufficient dross does not occur. Therefore, when it is rubbed off, a physical external force is applied to the skin. There was a problem that a heavy load was exerted on the skin and an excessive burden was placed on the skin.

In the case of a gommage cosmetic using a film-forming water-soluble polymer, the minimum amount of the film-forming water-soluble polymer required to sufficiently remove the residue from the gommage agent in a short period of time is a formulation. Has a low viscosity, and has the drawback that it drops off from the skin during use and that the formulation is not familiar to the skin. On the other hand, if a large amount of film-forming water-soluble polymer is added in order to provide appropriate viscosity with excellent usability, gelation will not be possible at low temperature and application will not be possible, and drainage and viscosity decrease will occur at high temperature, and stable There was a problem in sex and usability.

In order to solve the above-mentioned problems, the present invention is excellent in storage stability with time, particularly storage stability at high temperature, and has a short time until the appearance of dregs due to a gommage agent and has usability. The object was to provide an excellent gommage cosmetic composition.

[0006]

Means for Solving the Problems The inventors of the present invention have made extensive studies in order to solve the above-mentioned problems, and as a result, by combining a film-forming water-soluble polymer with a specific silicic acid anhydride, The inventors have found that they have excellent storage stability over time at high temperatures, have excellent quality as gommage cosmetics, and have excellent usability, and have completed the present invention.

It is an essential component of the present invention as a gommage agent for scraping off the above.

As the component (A) used in the present invention,
It is not particularly limited as long as it is a film-forming water-soluble polymer that can be used in cosmetics and that can impart appropriate viscosity and spreadability to the system, and can be natural, synthetic, semi-synthetic anionic, cationic, Any of amphoteric and nonionic compounds may be used, or these may be used in combination. For example, guar gum, xanthan gum, locust bean gum, tragacanth gum, gum arabic, gellan gum, sodium chondroitin sulfate, hyaluronic acid, sodium alginate, alginates such as calcium alginate, carrageenan, quince seed, galactan, mannan, starch, pectin, dextrin, curd. Natural water-soluble polymers such as orchid, casein and collagen, semi-synthetic water-soluble polymers such as methylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, hydroxyethylcellulose, carboxymethylcellulose, carboxyvinyl polymers, alkyl-modified carboxyvinyl polymers, polyvinyl alcohol,
Examples thereof include synthetic water-soluble polymers such as polyvinylpyrrolidone and sodium polyacrylate, and one or more of these can be appropriately selected and used. Among these film-forming water-soluble polymers, sodium alginate is particularly preferable in that it does not require a standing time for drying the coating film at the time of use, is more likely to produce dust, and exerts the effect of the present invention.

The amount of the component (A) used in the present invention is 0.1% by mass to 10% by mass in the gommage cosmetic composition.
(Hereinafter, simply indicated by “%”) is preferable, and particularly preferably 1.5% to 5%. Within this range, it maintains an appropriate viscosity, does not cause gelation or drainage, and has excellent stability over time, and it does not drip during application, is easy to spread, and does not cause an excessive burden on the skin. , The residue from the gommage agent appears in a short time, and a sufficient gommage effect is obtained.

The silicic acid anhydride of the component (B) used in the present invention exhibits a thickening effect synergistically when used in combination with the film-forming water-soluble polymer of the component (A), and the product of the present invention is preserved. It improves stability, especially storage stability at high temperature.

Although there are various grades of silicic acid anhydride depending on the specific surface area and particle size, the silicic acid anhydride of the component (B) of the present invention has a specific surface area of 100 to 400 by the BET method.
m ² / g and average primary particle diameter of 7 to 16 nm, and within this range, the squeak unique to the powder is not felt after use, an effective thickening effect is exhibited, and excellent stability over time is achieved. You can get sex. In particular, in order to improve this effect, high-purity ultrafine silicic anhydride powder and ultrafine silicic anhydride powder partially mixed with aluminum oxide are preferable. Further, the silicic acid anhydride as the component (B) can be used after generally known surface treatment. Specifically, the AEROSIL 130, 200, 300, 380,

Specific examples include glycerin, 1,3-butylene glycol, dipropylene glycol, propylene glycol, sorbitol, polyoxyethylene glycol and the like. Among these, 1,3-butylene glycol, dipropylene glycol, and propylene glycol are particularly preferable in order to further shorten the time until the residue is removed by the gommage agent.

The weight ratio of the component (A) film-forming water-soluble polymer of the present invention to the component (C) polyhydric alcohol is preferably 1: 3 to 1:15, within this range. For example, it has an appropriate viscosity, the time until the residue is removed by the gommage agent is short, the usability is good, and the stability over time is excellent, and a sufficient gommage effect is obtained.

The gommage cosmetic composition of the present invention is a gel or cream when the component (A), the component (B) content, and the component (A) component (C) mass ratio are within the above ranges. It shows a semi-solid state from a paste that is not liquid such as a shape,
The viscosity is in the range of 5000 to 100,000 mPa · s (B-type rotational viscometer, measured at 25 ° C).

The form of blending is not particularly limited, but may be, for example, a cleansing agent such as a facial cleanser or a body shampoo, a pack agent, a cleansing agent, an emulsion for parts such as elbows and heels.
