Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to clean nails and fingers from yellowing and to impart gloss and smoothness to the nails.
Further, the present invention relates to a nail and limb cleaning agent which can also provide a moisturizing effect.

[0002]

2. Description of the Related Art In recent years, there has been an interest in making nails beautiful from a cosmetic viewpoint. However, stains such as yellowing of nails are difficult to remove with ordinary solid or liquid soap, and it is difficult to impart gloss and smoothness to nails. Therefore, development of a nail-specific cleaning agent, so-called nail bleach, has been desired. Conventionally, as a nail-specific cleaning agent, a tablet-type cleaning agent which uses an anionic surfactant as a cleaning component and is dissolved in water or hot water is known. In order to further promote the solubility in water or hot water. In addition, a tablet type compounded with an organic acid and a carbonate which foam by an acid-base reaction is also known. However, they do not have sufficient washing action for yellowing of nails and the like, and improvement thereof is desired. Also,
Ammonium thioglycolate, ammonium bisulfite, 1,4-dithiothreitol, tetrakis (hydromethyl) phosphonium chloride, L-cysteine (N-acetylcysteine) having an action of partially reducing structural cystine in nail keratin A nail cleaner containing a reducing agent such as the above has also been proposed, and has been confirmed to be effective in cleaning yellowing of nails and fingers. By the way, instead of the purpose of cleaning, in order to impart gloss and smoothness to the nails, the nails are polished with a file or the like, or polished while massaging the nails with a cream or the like containing an abrasive or the like. ing. However, there is no known nail bleach that imparts gloss and smoothness to the nails at the same time as washing the nails,
In particular, there is no known nail cleaning agent that can clean a nail and impart gloss and smoothness to the nail only by immersing a finger in water or hot water in which the nail cleaning agent is dissolved. Also, recent women are more interested in fingertip care,
There is a need for a product that can easily care for nails and limbs.

[0003]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to clean dirt such as yellowing of nails and fingers and to impart gloss and smoothness to nails, and at the same time to limbs and fingertips. It is an object of the present invention to provide a nail and limb cleaning agent capable of imparting a moisturizing effect to a nail.

[0004]

Means for Solving the Problems The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, in addition to a reducing agent having a cleaning action, a powder having a specific polishing action, sodium carboxymethylcellulose and dextrin have been added. By mixing and using an amount of carbonate and an organic acid that generate carbon dioxide gas when used in contact with water or hot water, fingers and limbs are dissolved in water or hot water in which a nail and limb cleaning agent is dissolved. The present inventors have found that washing of nails and limbs and imparting gloss and smoothness to nails can be performed simultaneously only by immersion, and the present invention has been completed. According to the present invention, an amount of carbonate and organic acid that generates carbon dioxide gas when used in contact with water or hot water, a reducing agent, and titanium oxide powder,
A solid and / or powdered nail and limb cleaner comprising sodium carboxymethylcellulose and dextrin is provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The nail and limb cleaner of the present invention comprises:
A detergent for dissolving in water or hot water and washing fingers and limbs in the hot water or hot water to wash nails and the like, wherein carbonates and organic acids as essential components, a reducing agent, titanium oxide powder, It contains sodium methylcellulose (hereinafter abbreviated as CMC) and dextrin. The form of the nail and limb cleaning agent of the present invention may be in the form of a powder, a tablet or the like using an excipient, or a mixture of a powder and a tablet.

The organic acids and carbonates used in the nail and limb cleaner of the present invention are foamed by an acid-base reaction by dissolving the nail and limb cleaner in water or hot water. In addition to improving the solubility, the cleaning action by the reducing agent or the like is improved, and furthermore, it acts to promote finger or nail bed blood circulation. In addition, the titanium oxide powder described later also acts to convect water or hot water so as to impart luster and smoothness to the nail by the polishing action. Examples of the organic acid include succinic acid, adipic acid, malic acid, citric acid, glutamic acid, fumaric acid, tartaric acid, and the like. Examples of the carbonate include sodium carbonate, sodium hydrogen carbonate, potassium carbonate and the like. The mixing ratio of these organic acids and carbonates is not particularly limited as long as carbon dioxide gas is generated when dissolved in water or hot water.
Although it can be appropriately selected, usually, the organic acid is preferably used in an amount of 10 to 45% by mass, particularly preferably 2% by mass, in the nail and limb cleaner.
0 to 40% by weight, while the carbonate is usually preferably in the tablet preferably 10 to 45% by weight, particularly preferably 20 to 4% by weight.
0% by mass. The ratio between the organic acid and the carbonate is generally 1: 1 by mass.

The reducing agent to be added to the nail and limb cleaner of the present invention includes, for example, L-cysteine hydrochloride, sodium oxalate, sodium thiosulfate or a mixture thereof. In view of the above, use of L-cysteine hydrochloride, sodium oxalate or a mixture thereof is preferred. The mixing ratio of the reducing agent can be appropriately selected depending on the type thereof, but the concentration of the reducing agent is preferably 0.05 to 5 g / water or hot water to be dissolved.
It may be blended for each single use so that the amount becomes 1 liter, and it is usually preferable to blend it in the nail and limb cleaner at a ratio of 0.1 to 10% by mass.

[0008] The titanium oxide powder to be added to the nail and limb cleaning agent of the present invention acts as an abrasive or the like to impart gloss and smoothness to the nail. At this time, as an abrasive,
Without blending titanium oxide powder, for example, zinc oxide powder,
When using silicic anhydride powder, zeolite powder, or a mixture thereof, a sufficient polishing effect cannot be obtained, and gloss and smoothness cannot be sufficiently imparted to a target nail. The average particle diameter of the titanium oxide powder is usually 0.1 to
0.3 μm, particularly preferably an average particle size of 0.15 to 0.2
It is about 5 μm. The mixing ratio of the titanium oxide powder is not particularly limited and may be appropriately selected as long as it can impart gloss and smoothness to the nail according to the balance with other components. The mixing ratio of titanium oxide is usually preferably 0.01 to 5% by mass, particularly preferably 0.05 to 5% by mass in the nail and limb cleaner.
１1% by mass.

C formulated in the nail and limb cleaner of the present invention
In particular, MC and dextrin sufficiently exert the nail polishing action of the titanium oxide powder and maintain the polishing action. The dextrin is not particularly limited as long as it is usually a dextrin having an emulsifying and dispersing action. The mixing ratio of dextrin is usually preferably 0.1 to 30% by mass, particularly preferably 0.1 to 15% by mass in the nail and limb cleaning agent, and is usually about the same as the above titanium oxide powder. It is desirable to mix them. On the other hand, C
The compounding ratio of MC is usually 0.05 to 5% by mass, particularly preferably 0.5 to 5% by mass in the nail and limb cleaner.
1% by mass, usually 0.04 to
A 10-fold amount is desirable. When the mixing ratio of the CMC and the dextrin is small, the titanium oxide powder may settle as the foaming of the organic acid and the carbonate becomes weak, and the polishing effect may be reduced. On the other hand, when the amount is large, the moving speed of the titanium oxide powder in the liquid is reduced, and a desired polishing action may not be obtained. Therefore, the mixing ratio of CMC and dextrin is adjusted so that such a fear does not occur. It is preferable to appropriately select from the above range.

In the nail and limb cleaner of the present invention, in order to prepare a tablet using the above essential components and the like, various excipients, stabilizers, binders, disintegrators and the like are optionally blended.
It can be prepared by an ordinary tablet molding method or the like. The size of the tablet is not particularly limited, and is usually 0.3 to 5 cm.
