A hair color stripper composition for oxidative hair dye

The present invention relates to a hair color stripper composition containing a reducing agent, an anionic surfactant, a solvent, a carrier, a thickener, and the like to remove an oxidized pigment of the hair, and more particularly, 5 to 20% by weight of a reducing agent and 10 to 30% by weight of a solvent. A new hair color stripper whose main mechanism is to dissolve the polymerized oxidized pigment itself, containing%, 1 to 5% by weight, 5 to 10% by weight of anionic surfactant, 0.1 to 1% by weight of carrier, and other ingredients. will be.

Hair dyes are classified into temporary hair dyes, semi-permanent hair dyes, and permanent hair dyes. The permanent hair dyes include oxidation hair dyes, metal hair dyes, and vegetable hair dyes depending on the dye used.

Most hair hair dyes conventionally used are oxidative hair dyes using oxidative dyes, and these hair dyes are easy to cause skin allergies, and because strong alkali ingredients are used, the hair ingredients are dissolved to damage hair.

There is a permanent hair dye using a metal salt to solve the problems of skin irritation and hair damage, these are also divided into two solutions, such as a metal salt solution and reducing solution to reduce the dye, there is also a disadvantage in use.

Meanwhile, techniques for removing oxidative pigments in hair have been introduced so far and have been released as products. In particular, reducing agents such as sodium dithionite, sodium hydroxymethanesulfinate (Rongalite), cysteine, ATG (Ammoniumthioglycolate) and peroxides such as sodium perborate, sodium percarbonate, potassium persulfate, ammonium persulfate, etc. This effect is known.

The color strip mechanism is also divided into oxidation and reduction depending on the nature of the raw material.

Oxidation products are mainly composed of peroxides, and they do not differ from the existing bleaching agents. The oxidation mechanism does not remove color from the hair, but changes the pigment molecule itself in the hair with strong oxidizing power at high pH, thereby losing color. Thus, there are disadvantages in terms of damage and irritation.

On the other hand, the reduction mechanism is to make a polymerized oxidized pigment into a monomer as a reducing agent, and then to remove the monomer pigment from the hair with a solvent and a detergent. Currently, the product is mostly longalite (rongalite). This product has a good effect of reducing the polymer to monomer, but has the disadvantage that the color of the hair gradually changes or the extra monomer pigment interferes with dyeing when it is dyed differently because the monomer cannot be completely removed from the hair. In addition, after the procedure, the hair remains odorous, making the consumer uncomfortable.

In order to solve the above problems, the present inventors have studied a hair color stripper composition which minimizes damage and irritation by only reacting with pigment oxide, and use a reducing agent having a lower reducing power than a reducing agent used in a conventional desalting agent, and using a solvent, The hair color stripper composition containing anionic surfactants, carriers, thickeners and the like has been found to minimize hair damage and irritation by dissolving the polymer pigment itself as the main mechanism, thus completing the present invention.

Accordingly, an object of the present invention is a hair color stripper which contains a reducing agent, a solvent, an anionic surfactant, a carrier, a thickener, and other components, which have little effect on the melanin pigment and the hair protein and remove only the oxidative pigment from the hair to minimize hair damage and irritation. It is to provide a composition.

In order to achieve the above object, the color stripper composition of the present invention is 5 to 20% by weight reducing agent, 1 to 5% by weight thickener, 10 to 30% by weight solvent, 5 to 10% by weight anionic surfactant, 0.1 to 1 carrier It is characterized by containing a weight percent. In addition, the composition may further contain other components, that is, purified water, auxiliary thickeners, flavors, preservatives, pH adjusting agents and the like.

Hereinafter, the present invention will be described in detail.

Looking in detail with respect to the reducing agent, solvent, thickener, carrier, anionic surfactant contained in the hair color stripper composition according to the present invention.

The reducing agent used in the hair color stripper composition of the present invention is a reducing agent commonly used in the pump agent ATG (Ammoniumthioglycolate) or cysteine. The reducing agent has two effects of weakening the binding force between the hair protein and the polymer pigment and reducing the polymer pigment to the monomer. However, in the present invention, the former has a specific gravity to minimize the residual monomer. Therefore, by dissolving the polymer pigment molecule, which has a weak binding force with the hair protein, with a solvent and a detergent, it is possible to compensate for the disadvantage that the extra monomer dye is re-stained later. The reducing agent is contained in the composition in an amount of 5-20% by weight.

In addition, solvents used to dissolve the oxidized pigments include ethyl alcohol, isopropyl alcohol, and the like. The solvent may be used in an amount of 10 to 30% by weight based on the total weight of the composition, and may be used alone or in combination.

In addition, as anionic surfactants that wash away the dissolving pigments, ammonium lauryl sulfate (ALS), ammonium laureth sulfate (ALES), sodium laruyl sulfate (SLS), sodium laureth sulfate (SLES), etc. It is used in an amount of 5 to 10% by weight based on the total weight.

In addition, a carrier that facilitates the penetration of active ingredients into the hair is salicylic acid, which has a pigment removal enhancing effect. The carrier is used in an amount of 0.1 to 1% by weight based on the total weight of the composition.

In addition, the thickener used in the present invention is a water-soluble polymer such as hydroxyethyl cellulose (Hydroxyethylcellulose), polyquaternium (Polyquaternium), cellulose gum (Cellulose gum), etc., the amount is 1 to 5% by weight based on the total weight of the composition to be.

Moreover, it is preferable that the hair color stripper composition of this invention is pH 4-5.

On the other hand, the other components used in the present invention are conventionally known arbitrary ingredients for maintaining the basic physical properties and quality, specific examples are purified water, auxiliary thickeners, fragrances, preservatives, pH adjusting agents, etc. This is used.

Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited only to these examples.
