Description

Composition for hair bleaching agent {COMPOSITION FOR HAIR DECOLORATION AGENT}

The present invention relates to a composition for a hair bleaching agent, and more particularly, to a hair bleaching agent composition for alleviating hair damage due to bleaching and improving hair softness by including cochineal pigment and gardenia yellow pigment, which are natural pigments. will be.

Hair bleaching (DECOLORATION, BLEACHING) is the removal of natural hair pigment from the hair, and the bleaching effect occurs as the melanin pigment in the hair is oxidized and decomposed by the oxidizing agent that generates oxygen.

In general, hair bleaching agents are divided into 1 formulation, 2 formulations, and 3 formulations according to the composition of the oxidizing agent and the hair bleaching agent powder.

The one-part hair bleaching agent consists of a transparent liquid or emulsion oxidizing agent containing hydrogen peroxide as a main component, and the two-part hair bleaching agent consists of a hair bleaching powder first agent and a transparent liquid or emulsion oxidizing agent containing hydrogen peroxide as a main component. The three-part hair bleaching agent consists of an alkaline emulsion phase 1 agent, a transparent liquid or emulsion phase oxidizing agent containing hydrogen peroxide as a main component, and a hair bleaching powder 3 agent.

At this time, the hair bleaching powder has persulfate salts as a main component as an oxidation promoter, and includes an alkali agent for proper oxygen generation, a thickener for increasing usability, etc., thereby promoting the oxidative decomposition reaction of melanin in the hair bleaching agent. It works to decolorize.

However, when the powder composition for bleaching hair and the oxidizing agent are mixed, not only a vigorous oxidation reaction occurs, but also the degree of damage to the hair increases due to high alkali conditions, and there are disadvantages in that it stimulates the scalp and worsens the feel of the hair after bleaching. .

In order to improve these disadvantages, Korean Patent Laid-Open No. 10-2003-0024352 proposes a composition for hair bleaching agent containing persulfate salts as a main component. However, the prior-published patent had difficulties in alleviating hair damage only by using persulfate salts, and had disadvantages in that hair softness and gloss were not improved.

In addition, Korean Patent Registration No. 10-0725650 has proposed a hair bleaching composition containing henna and aloe. However, the previously registered patent has a disadvantage in that the hair and scalp are protected to some extent due to the addition of henna and aloe, but the bleaching effect is poor.

Accordingly, it is an object of the present invention for a hair bleaching agent to alleviate hair damage and scalp irritation, and to improve hair gloss, softness, etc., without inhibiting the bleaching effect, by including cochineal pigment and gardenia yellow pigment, which are natural pigments. to provide a composition.

The composition for hair bleaching of the present invention for achieving the above object includes a natural pigment as an active ingredient, wherein the natural pigment is cochineal pigment, gardenia yellow pigment, or both.

The natural pigment is characterized in that it contains the cochineal pigment and the gardenia yellow pigment in a weight ratio of 1:0.1 to 10.

Based on 100% by weight of the total composition, it is characterized in that it contains the natural pigment in an amount of 0.1 to 20% by weight.

It is characterized in that it further comprises a cassia bark extract, a sardipul extract and a paracreth extract as an active ingredient.

According to the composition for bleaching hair of the present invention, there is an advantage in that hair damage and scalp irritation are alleviated, and hair gloss, softness, etc. are improved without impairing the bleaching effect.

Hereinafter, the present invention will be described in detail.

The composition for hair bleaching according to the present invention can be applied to both formulations, 2 formulations, and 3 formulations, as well as 1 formulation, but is preferably applied to 2 formulations and 3 formulations, and is applied to powder for hair bleaching rather than an oxidizing agent will become That is, the present invention is applied to a powder composition for hair bleaching to reduce hair damage due to bleaching and to improve the shine and softness of hair.

The composition for hair bleaching according to the present invention includes a natural pigment as an active ingredient, wherein the natural pigment is cochineal pigment, gardenia yellow pigment, or both.

The cochineal extract dye is obtained by extracting the pigment contained in the female insect called cochineal (Coccus cacti L., 'cochineal'), which is parasitic on cacti, with an alcoholic solution, and removing the alcoholic solution. , is currently being widely used as a natural pigment in most developed countries such as Korea, EU, USA, and Canada. The main component of this cochineal pigment is carminic acid (C ₂₂ H ₂₀ O ₁₃ ; molecular weight 429.39), and the carminic acid relieves hair damage caused by intense oxidation and high alkali conditions during hair bleaching, and also stimulates the scalp. It relieves and improves hair softness and shine.

In the present invention, the cochineal pigment can be extracted and used directly from cochineal, and it is also possible to purchase and use from commercially available products, but is not limited thereto.

The gardenia yellow extract (Gardenia Yellow Extract) is a pigment obtained by extracting or hydrolyzing gardenia or fruit with water or alcohol, and its main component is crocin. Crocin, which is the main component of the gardenia yellow pigment, alleviates hair damage caused by intense oxidative reactions and high alkali conditions during hair bleaching, and imparts a conditioning effect to the hair.

Gardenia yellow pigment according to the present invention can be directly extracted from gardenia and used, and it is also possible to purchase and use from commercially available products, and this is not limited.

In addition, in the present invention, it is also possible to use each of the cochineal pigment and the gardenia yellow pigment alone, and it is also possible to use a mixture thereof. However, when the cochineal pigment is used alone, the degree of hair damage is remarkably alleviated, but the improvement effect on hair softness and gloss is small. Since the degree of relaxation is small, it is most preferable to mix and use them. At this time, the mixing ratio of the cochineal pigment and the gardenia yellow pigment is preferably 1:1 to 10 by weight, but is not necessarily limited thereto.

In addition, the natural pigment, which is an active ingredient of the present invention, is preferably contained in an amount of 0.1 to 20% by weight based on 100% by weight of the composition for hair bleaching. This is because the effect of cannot be expected, and if it exceeds 20% by weight, no further enhanced effect can be expected due to the increase in usage.

In addition, in the composition for hair bleaching of the present invention, the rest of the natural dye is composed of a general bleaching powder composition, and is composed of an oxidation accelerator, an alkali agent, a thickener, a hair protectant, a softener, and a conventional additive. That is, the ingredients other than the natural dye are composed of commercially available general hair bleaching powder.

Here, the oxidation promoter is used in a general hair bleaching composition, and at least one of water-soluble salts of persulfate, perborate, and percarbonate may be used.

In addition, the alkali agent is to increase the pH when mixed with the oxidizing agent, ammonium sulfate, sodium silicate, etc. may be used.

And hydroxyethyl cellulose, carboxymethyl cellulose sodium, etc. can be used as the thickener, keratin, collagen, etc. as a hair protectant, EDTA-2Na as an emollient, fragrance, conditioning agent, PVP, silica as an additive , magnesium oxide and the like can be applied.

In addition, these oxidation promoters, alkali agents, thickeners, hair protectants, softeners and additives are well known in the art to which this technology belongs, and the type, amount, etc., are not limited, and are known as conventional bleaching agents in addition to the ingredients listed above. It goes without saying that various additives may be further added.

As described above, the bleach composition including a natural pigment as an active ingredient has an advantage in that it has an excellent bleaching effect, prevents hair damage, and can impart a conditioning effect to the hair.

On the other hand, in the present invention, in order to increase the hair protection effect and scalp damage mitigation effect due to discoloration, cassia bark extract and sardipul extract may be further included.

In this case, the blending ratio is preferably 0.1 to 3% by weight of the cassia bark extract and 0.1 to 3% by weight of the sardinia extract based on 100% by weight of the composition for the bleaching agent.

Cassia (Cercidiphyllum Japonicum S et Z) is a deciduous broad-leaved arboreous tree of the dicotyledonous plant Heterinus, Cassiaceae, and its extract minimizes damage by protecting hair during bleaching, and also acts to alleviate damage to the scalp.

Sade grass is a perennial herb belonging to the genus Compositae and Sonchus distributed mainly in wetlands and brackish areas of reclaimed land, such as Korea, Japan, China, and Russia, and its extract works to minimize scalp irritation.

At this time, the extraction method of the extract is not limited, and at least one of leaves, flowers, roots, and stems of cassia bark or sardinia is used as a sample, and water, methanol, ethanol, propanol ( propanol), isopropanol, butanol, etc., using at least one of alcohols having 1 to 4 carbon atoms as a solvent, hot water extraction method, cold extraction method, reflux cooling extraction method, solvent extraction method, steam distillation method, ultrasonic extraction method, elution It can be extracted by one of a method and a compression method. In addition, the desired extract may be further subjected to a conventional fractionation process, may be purified using a conventional purification method, may be diluted, concentrated or dried, and the practice is not limited.

In addition, in the present invention, in order to improve hair gloss, softness, etc. caused by discoloration, and to alleviate an irritating odor generated during discoloration, Paracres extract may be further included.

At this time, the blending ratio is preferably 0.1 to 3% by weight of the Paracres extract with respect to 100% by weight of the composition for bleaching agent.

Paracress (Acmella oleracea) is an annual or perennial plant of the Asteraceae family of the order Asteraceae, and its extract gives hair conditioning effect and improves usability by alleviating the irritating odor that occurs during bleaching.

The extraction method of Paracreth is the same as that of the cassia bark extract or sardinia extract described above, and as the sample, one or more of the flowers, leaves, stems and roots of Paracris may be used.

(Test Example 1)

The degree of damage to hair according to Examples and Comparative Examples was evaluated.

The degree of damage to the hair was compared by measuring the amounts of cysteic acid and cystine present in the hair using HPLC.

Hair is composed of amino acid cystine bonds, and cystine bonds are decomposed by chemical treatment such as bleaching to further produce cysteic acid. That is, the more the hair is damaged, the greater the amount of cysteic acid. Therefore, the degree of damage to hair can be compared by analyzing the amounts of cystine and cysteic acid present in the hair after bleaching.

In this test, the ratio of cystine to cysteic acid present in hair (Cystine(ppm)/Cysteic acid(ppm)) was used. The smaller this ratio value, the more hair damage, and the larger this value, the less hair damage. .

For discoloration by the sample, 12 skilled cosmetologists mix the powder compositions of Examples and Comparative Examples with a 6% solution of hydrogen peroxide, which is an oxidizing agent commonly used in beauty salons, in a 1:3 weight ratio, and then put it on a wig mannequin. Each was applied and left for 30 minutes, washed with running lukewarm water, and then dried with a dryer.

And 24 hours after drying, a sample of 3 cm or less under the hair, which is the most damaged part of the hair, was tested. The results are shown in Table 3 below.
