Description

Acid hair dye composition {ACIDIC HAIRDYE COMPOSITION}

The present invention relates to an acid hair dye that is excellent in dyeing property and does not have color on skin or clothes.

Although many proposals have been made on acid dyes, small pigment concentrations and low concentrations of penetrants and acids are used mainly for use as hair dressings, etc. The hair dye that hides or makes the white hair inconspicuous is extremely lacking, and the effectiveness as a dye is insufficient. Conversely, those with high pigment concentrations and high concentrations of penetrants and acids are used as hair dyes, have a high degree of contamination on the skin, and their skin or clothes become very stained even after use. This product is only used for the products used in the home or in general households, so as not to contaminate the skin or clothing, and only the product that needs to be washed out after use.

The present invention is stable even in the strongly acidic region (pH 1.5 to 4.0), rich in fluidity, excellent in use feeling, and thickened without sticking to the skin and clothes after use and without needing to be washed off. Iii) to use one means using the means to conceal white hair inconspicuous, and to provide an acid hair dye composition that can dye hair invisible to white hair in 4 to 5 uses.

As a result of careful examination to solve this problem, the present inventors have formulated an acidic hair dye in a good balance of essential pigments "acid", "acid", "aromatic alcohol", "lower alcohol", "thickener" and "water". This makes it possible to conceal white hair inconspicuous in one use and to dye the hair inconspicuous in four to five uses, without needing to wash the skin or clothes after use and washing it off. The high effective acid hair dye composition was discovered.

The acidic hair dye composition of the present invention comprises 0.01 to 1% of one or two or more types of acid dyes, 0.1 to 10% of an acid as a pH adjusting agent, 1 to 20% of an aromatic alcohol as a penetrant, and a lower alcohol as a solvent. It is characterized by mix | blending 0.01 to 5% of 20% and a high molecular compound as a thickener.

In addition to the above main components, the acidic hair dye composition of the present invention contains preparations commonly used in this field, such as ultraviolet absorbers, antioxidants, stabilizers, etc., with the remainder being water.

In the present invention, as the acid dye, an oxidative hair dye or a legal dye commonly used in acid dyes can be used. Preferably it is a tar type pigment | dye, For example, Red 2, Red 102, Red 106, Red 213, Red 215, Red 227, Red 401, Red 504, Yellow 4, Yellow 5, Yellow 203, yellow 205, green 3, green 204, green 205, blue 1, blue 203, blue 403, black 401, purple 401, orange 205, brown 201 can do. These pigments can be used 1 type or in combination or 2 or more types.

The acid dye may be added in an amount of 0.01 to 1% by weight, preferably 0.05 to 0.5% by weight, based on the total amount of the dyestuff. If the number of hair dyes is not repeated 10 times or more at 0.01% or less, the desired color cannot be reached, and at 1% or more, it becomes difficult to dye the hair with a good color.

As an acid as a pH adjuster, any of an inorganic acid and an organic acid can be used, Preferably, an organic acid is used. For example, organic acids, such as citric acid, succinic acid, tartaric acid, lactic acid, malic acid, fumaric acid, maleic acid, glycolic acid, inorganic acids, such as hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid, are mentioned. In addition, these acids may be used in combination with sodium, potassium or ammonium salts of these acids for the purpose of imparting buffering capacity and the like.

The compounding quantity of these acids is selected and mix | blended so that a hair dye liquid may be pH 1.5-4.0, Preferably pH 1.5-3.5 about strong acidity at the time of hair dye application.

Aromatic alcohols as penetrants are used not only to promote the penetration of dyes into the hair, but also to impart smoothness, moist feeling and adequate moisture retention to the hair after hair dyeing. For example, benzyl alcohol, phenylethanol, etc. can be used. Preferably benzyl alcohol.

Lower alcohol as a solvent can be mix | blended with what is normally used for hairdressing materials. Linear or branched alcohols having 1 to 4 carbon atoms may be used, and examples thereof include methanol, ethanol, propanol, isopropanol, butanol, ethylene glycol, 1,3-butylene glycol, and preferably ethanol. do. Although the compounding quantity of a lower alcohol changes with other compounding components, it is used in 1 to 20% of range with respect to the whole amount of hair dye. In 1% or less, since the function as a solvent is small, turbidity or separation of a liquid appears, and in 20% or more, workability at the time of dyeing falls.

The hair dye of the present invention uses a thickener to prevent unnecessarily dripping of the hair dye during use and to improve handleability. The high molecular compound as a thickener can use either a natural or synthetic high molecular compound. For example, natural polymers such as gum arabic, guar gum, carrageenan, sodium arginate, xanthan gum, methylcellulose, CMC, cationic starch, poly (meth) acrylic acid, poly (meth) acrylic acid ester, polyvinyl alcohol, etc. Higher fatty acid esters such as synthetic polymers and polyethylene glycol higher fatty acid esters; Preferably it is xanthan gum.

The hair dye composition of the present invention may be blended with a humectant, an anti-dandruff agent, an antioxidant, a UV absorber, a fragrance or the like used in this field as needed.

The hair dye of the present invention is not intended to obtain hair of a color desired by one hair dye, but is intended to obtain a deeply moistened color by dyeing the hair 3 to 5 times or more in between. Therefore, even if the number of hair dyes is repeated, the hair does not go bad and does not adversely affect health.

The hair dyeing may be performed after the hair is dyed first, after 30 minutes or more, preferably after 1 day to 7 days (1 week) or more, for example, every 3 weeks. Preferably, the hair is washed, i.e., triturated, before subsequent hair dyeing.
