Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment agent, the purpose of which is to alleviate hair damage due to permanent wave treatment, prevent cut hair, split ends, etc., and prevent wave down after treatment. Another object of the present invention is to provide a hair treatment agent capable of retaining the wave applied to the hair for a long period of time.

[0002]

BACKGROUND OF THE INVENTION Permanent wave treatment is performed for the purpose of imparting a wave to hair to produce a hair style different from that of straight hair. Permanent wave agents used are usually a first liquid containing a reducing agent such as thioglycolic acid or cystine as a main component, and a second liquid containing an oxidizing agent such as bromate or hydrogen peroxide as a main component. A two-component cold waving agent composed of The permanent wave is to first wrap the hair around a rod of an arbitrary size, and in this state the first liquid is allowed to penetrate into the hair, and the cysteine bond in the hair keratin is reduced and opened by the first liquid to cut the cysteine bond. , To soften the hair and form a wave by winding it around the rod. Then, the first liquid is removed by washing with water or the like, and then the second liquid is permeated into the hair, and the cut cysteine bond is repaired by oxidative closure to give a wave to the hair. Since such a two-component cold wave agent can give a sufficient wave to hair at room temperature, it is currently used for most permanent wave treatments.

[0003]

2. Description of the Related Art Generally, a wave of hair formed by a permanent wave treatment tends to be broken down over time due to repeated use of shampoo and the like, and a wave down tends to be observed with time. . Therefore, there has been a strong demand among consumers for retaining the wave of the hair after the perm treatment for a long period of time. To meet this request,
Prolongs the treatment time of permanent wave agent on hair,
A method of forming a stronger wave is adopted. That is, in order to make the penetration time of the first liquid into the hair sufficient, the treatment time with the first liquid is lengthened, the cysteine bond is sufficiently cleaved by the reduction open chain, and the hair of the hair is wound around the rod. And the subsequent second liquid permeation time into the hair is similarly lengthened to sufficiently oxidize and close the open chain cysteine bond to fix the formed wave. Has been adopted from the past.

[0004]

However, when the treatment time for the hair with the permanent waving agent is prolonged in this way, the chemical treatment time such as reduction and oxidation becomes long, resulting in great damage to the hair. Therefore, there is a problem that hair such as split ends, broken hair, and split hair is damaged or deteriorated. Therefore, in the industry, it is desired to create a hair treatment agent that can minimize damage to the hair due to permanent wave treatment, prevent wavedown after treatment, and retain the wave applied to the hair for a long period of time. It was

[0005]

In the present invention, the above-mentioned conventional problems are solved by providing a hair treating agent characterized by containing a basic amino acid and hemin or hematin as essential components.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The constitution of the hair treatment agent according to the present invention will be described in detail below. In the hair treatment agent of the present invention, a basic amino acid and hemin or hematin are mixed as essential components. As the basic amino acid used as an essential component, known ones such as arginine (Arg) and lysine (Lis) are suitably used without particular limitation. Basic amino acids are
It has excellent penetrability and affinity for hair, penetrates into damaged hair after permanent wave treatment, effectively enhances the action of hemin or hematin described below on hair, and exhibits extremely good restorative power. . The basic amino acid is added in an amount of 0.1 to 5.0% by weight based on the total amount of the hair treatment agent. The reason for this is that if the amount of the basic amino acid compounded is less than 0.1% by weight, the effect of alleviating the damage to the hair associated with the permanent wave treatment and the effect of preventing wave down after the treatment are not well expressed. Unfavorable,
On the other hand, even if the amount is more than 5.0% by weight, the effect on hair damage and wavedown does not improve so much depending on the amount of addition, and there is a new problem of impairing system stability. This is because there is no such limitation, but the blending amount is not particularly limited in the present invention.

In the present invention, in addition to the basic amino acids mentioned above, hemin or hematin is also incorporated as an essential component. Hemin is, in a narrow sense, iron (III) porphyrin compound (C ₃₄ H ₃₂
O ₄ N ₄ Fe Cl) is also called chlorohemine, and in a broad sense, it refers to a complex salt formed by coordinating any acid ion with iron (III) porphyrin, and hematin is a structure in which the chlorine atom of hemin is replaced with a hydroxyl group. With iron (III) protoporphyrin (C ₃₄ H ₃₂ O ₄ N ₄ Fe (OH)). Both hemin and hematin are porphyrin-based compounds derived from animal-derived blood, and are present in the form of a complex with a natural protein. Such hemin or hematin effectively binds to the hair protein by the action of the above-mentioned basic amino acid, and exerts the function of strengthening the hair protein structure. This hemin or hematin is incorporated in an amount of 0.001 to 1.0% by weight, more preferably 0.005 to 1.0% by weight, based on the total amount of the hair treatment agent. The reason for this is that if the content of hemin or hematin is less than 0.001% by weight, the effect of alleviating the damage caused by the perm treatment and the effect of preventing the wavedown after the treatment are not sufficiently expressed, which is not preferable. In any case, the effect on hair damage and wave down does not improve much depending on the blending amount even if the blending amount exceeds 0% by weight, and the skin and clothes may be dyed during use. Although it is not preferable, the compounding amount is not particularly limited in the invention.

By thus blending both the basic amino acid and the components of hemin or hematin as essential components, the damage to the hair associated with the permanent wave treatment is alleviated, and the wavedown over time after the treatment is prevented. be able to. The reason why the two types of components are essential components is that the basic amino acid or hemin or hematin alone cannot firmly retain the protein structure of the hair after perm treatment.

The hair treatment agent according to the present invention comprising the above-mentioned essential components includes other components used in ordinary hair treatment agents and cosmetics, such as fragrances, surfactants, purified water, alcohols and polyhydric compounds. Alcohol, a humectant, an antiseptic, a pH adjuster, a thickener, an oil agent, an anti-ultraviolet agent and the like may be optionally added as needed as long as the effects of the present invention are not impaired. Further, the form of the hair treatment agent of the present invention is also optional,
Hair cream, hair liquid, hair lotion,
A liquid such as a hair spray, a shampoo, a hair conditioner, a cream, or the like may be formulated in any form without limitation.

Next, specific prescription examples of the hair treatment agent according to the present invention will be described, but the present invention is not limited to the following prescriptions. (Formulation Example 1) Hair cream Hematin 0.2 L-Arginine 0.3 Liquid paraffin 10.0 Isopropyl palmitate 10.0 Behenyl alcohol 5.0 Distearyldimethylammonium chloride 0.2 Cetyltrimethylammonium chloride 1.0 1,3 -Butylene glycol 5.0 Preservative proper amount Fragrance proper amount Purified water balance 100.0% (Formulation Example 2) Hair lotion hemin 0.2 L-arginine 0.3 dl-α-tocopherol 0.1 POE cured castor Oil (EO.50) 0.5 Citric acid 0.1 Hydroxyethyl cellulose 0.5 Diglycerin 5.0 Ethanol 10.0 Preservative proper amount Fragrance proper amount Purified water balance 100.0%
