Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dye removal agent. More specifically, the present invention relates to a dye removal agent for removing stains when a hair dye adheres to the skin.

[0002]

2. Description of the Related Art Conventionally, in order to remove stains such as hair dyes and lipsticks adhered to the skin, a remover containing an organic solvent or an alkaline agent, or a cleansing cream or shampoo has been used.

[0003]

However, there has been a drawback that the removal effect is not sufficient, the skin must be rubbed many times, and the skin becomes red. Further, those containing an alkaline agent such as ammonia or monoethanolamine or an abrasive to enhance the removal effect have a problem that the skin is strongly irritated and the skin becomes bulky after use.

[0004]

The present inventors have found that the above-mentioned drawbacks can be solved by using a fatty acid salt having 12 to 18 carbon atoms and an aromatic alcohol without using an alkali agent. .

The fatty acid salts having 12 to 18 carbon atoms used in the present invention include sodium, potassium, ammonium salts and monoethanolamine salts of saturated and unsaturated fatty acids having 12 to 18 carbon atoms. Examples include sodium, potassium, ammonium and monoethanolamine salts of lauric acid, myristic acid, oleic acid, palmitic acid, stearic acid and coconut oil fatty acids. Of these, sodium and potassium salts of coconut fatty acid, stearic acid and oleic acid are preferred. The compounding amount is 0.1-20% by weight,
Preferably it is 1.0 to 15% by weight. If the amount is less than 0.1% by weight, the removing effect is not sufficient, and the friction increases to increase skin irritation. If it is more than 20% by weight, no further effect can be expected.

The aromatic alcohol used in the present invention includes benzyl alcohol, cinnamon alcohol, phenylethyl alcohol, phenoxyethanol and the like. Among these, benzyl alcohol is particularly preferred in terms of the removal effect. The compounding amount is 0.1 to 2
0% by weight, preferably 1.0 to 10% by weight. 0.
If it is less than 1% by weight, a sufficient removal effect cannot be obtained,
Even if it exceeds 20% by weight, no further effect can be expected.

[0007] Examples of the dosage form of the hair dye of the present invention include liquid, emulsion, cream, gel, paste, aerosol and aerosol foam. Among these, an emulsion, a cream, a gel or a paste is preferred because it is easy to use.

Further, it is preferable to blend a polyhydric alcohol or saccharide as a moisturizing component in the dye removal agent of the present invention. This can protect the skin,
It can moisten the skin after treatment.
As polyhydric alcohols or sugars, glycerin, diglycerin, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol,
Polypropylene glycol, 1,3-butylene glycol, hexylene glycol, sorbitol, maltose, mannitol, xylitol, xylose, maltitol, sucrose, glucose and the like. Among these, glycerin, diglycerin, propylene glycol, dipropylene glycol, 1,3-butylene glycol and xylit are preferred. The amount is
It is 1 to 60% by weight, preferably 5 to 50% by weight.

Further, for the same purpose, hyaluronic acid,
Mucopolysaccharides such as chondroitin sulfate and chitin, N-methyl-2-pyrrolidone, glycyrrhizic acid, glycyrrhetinic acid, guaiazulene, aloe extract and malonie extract can also be blended.

Also, lower alcohols such as ethanol and isopropanol, and thickeners such as carboxyvinyl polymer, carboxymethylcellulose, hydroxyethylcellulose, quaternary nitrogen-containing cellulose ether, xanthan gum, carrageenan, sodium alginate, pectin, pullulan, furcellan, Arabic gum, gatch gum, tragacanth gum, agar powder, etc.
As oil, liquid paraffin, squalane, petrolatum,
Beeswax, lanolin, ceresin, olive oil, silicone oil and the like can be blended.

In addition, a nonionic surfactant, an amphoteric surfactant, a higher alcohol, a preservative, a bactericide, a plant extract, a fragrance and the like can be appropriately compounded.

The dye removal agent of the present invention is contained in absorbent cotton or the like, and is then wiped gently to give a hair dye such as an oxidative hair dye, an acidic hair dye or a temporary hair dye, or a skin dyed with lipstick or the like. On the other hand, there is a sufficient removal effect, and there is no irritation to the skin, and the treated skin does not become bulky.

[0013]

EXAMPLES Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples unless it exceeds the gist.

<Comparative experiment> A commercially available hair dye (Vigen Hair Color 6G manufactured by Hoyu Co., Ltd.) was applied to the upper arm of a person.
After leaving to stand for 30 minutes and washing with water, the operation of impregnating absorbent cotton with the dye removing agents of Example 1 and Comparative Examples 1 to 5 in Table 1 and wiping with the same strength was repeated 10 times. The removal effect of the hair dye and the skin irritation were evaluated according to the following criteria, and the results are shown in Table 1.

[0015]

[Table 1]

Note: The numbers in the table represent% by weight. Comparative Example 3 is a commercially available shampoo: Vigen Pair shampoo manufactured by Hoyu Co., Ltd. Comparative Example 4 is a commercially available soap: milk soap manufactured by Milk Soap Kyojinsha. Comparative Example 5 is a commercially available destaining remover having the following composition.

Comparative Example 5 (% by weight) Polyoxyethylene (9) lauryl ether 3.0 Strong aqueous ammonia 2.0 Isopropanol 10.0 Purified water Balance

<Evaluation Criteria> (1) Removal effect 効果: almost removed Δ: Some coloring remains. ×: Almost no removal, coloring remains. (2) Skin irritation…: No redness or bulkiness, same state as before treatment. Δ: Slight redness and dryness are recognized. ×: Redness and bulkiness are observed.

Example 2 (% by weight) Sodium oleate 6.0 Benzyl alcohol 6.0 Propylene glycol 25.0 Xanthan gum 0.5 Purified water Remainder A gel-like destaining remover having the above composition was prepared, and a commercially available acid was removed. Hair dye (Hoyu mild color made by Hoyu Corporation)
When used on the skin stained with, the removal effect was excellent as in Example 1, and no skin irritation was observed.

Example 3 (% by weight) Potassium coconut oil fatty acid 8.0 Benzyl alcohol 6.0 1,3-butylene glycol 20.0 Purified water Remainder A destaining remover for waxy solid having the above composition was prepared and commercially available. When applied to the skin dyed with the temporary hair coating (Vigen Quick Touch manufactured by Hoyu Co., Ltd.), the removal effect was excellent as in Example 1, and no skin irritation was observed.
