Description

Applied for application of Article 30, Paragraph 2 of the Patent Act Distributed by requesting the dispatch of a pamphlet describing the treatment agent for hair transformation on September 8, 2020

TECHNICAL FIELD The present invention relates to a first agent containing a reducing agent, which is a treatment agent for hair transformation used in hair transformation treatments such as wave formation and curly hair straightening.

In hair transformation treatments involving hair reduction treatment, typified by permanent wave treatment and straight perm treatment, the hair is oxidized after the reduction treatment to fix the transformation.

In addition, it is known that hair is damaged due to treatments such as face washing, brushing, dryer, perm, hair coloring, bleaching, drying, and environmental stress such as ultraviolet rays. Due to repeated exposure, the hair loses its moist feeling, suppleness, smoothness, firmness, luster, etc., and such damage tends to increase toward the tip of the hair.

Here, when such damaged hair is subjected to a hair deformation treatment, the permeation of the hair deformation treatment agent is excessively promoted in the damaged portion, resulting in increased hair deformation, which is often seen at the ends of the hair. There is a problem that the hair cannot be uniformly deformed in the damaged portion and the less damaged portion near the root of the hair.

Therefore, hair cosmetics have been proposed to avoid such inconveniences. More specifically, at least one water-soluble polymer selected from the group consisting of an anionic water-soluble polymer, an amphoteric water-soluble polymer and a nonionic water-soluble polymer, a silylated peptide, an organic acid and an acidic Hair cosmetics containing both or either one of amino acids and polyether silicone have been proposed. It is also described that by applying such a hair cosmetic to the damaged part before perming, the hair can be uniformly wavy (see, for example, Patent Document 1).

In addition, a permanent agent containing a reducing agent, an acylamino acid salt selected from acylmethyltaurate, acylglutamate, difatty acid acylglutamic acid lysine, betaine alkyldimethylaminoacetate, and bisethoxydiglycol cyclohexanedicarboxylate is proposed. It is It is also described that by using such a permanent agent, it is possible to provide a permanent agent that suppresses the dry feel of hair due to hair damage and is excellent in deforming hair (for example, Patent Document 2). reference).

Japanese Patent No. 3623376 JP 2019-210232 A

However, in Patent Literature 1, it is necessary to apply a hair cosmetic to the hair before performing the hair transformation treatment, so there is a problem that it takes time and effort, and the hair transformation treatment becomes complicated.

In addition, in Patent Document 2, although it has the effect of suppressing dry feeling, it excessively deforms the damaged part like a general perm agent, so the damaged part and the less damaged part of the hair , there is a problem that it becomes difficult to deform the hair uniformly.

Therefore, the present invention has been made in view of the above problems, and is capable of obtaining a good hair deformation effect, and at the time of carrying out the hair deformation treatment, the entire hair can be treated without using a treatment agent in advance. To provide a treatment agent for deforming hair, capable of uniformly deforming the hair and improving smoothness and suppleness of the finished hair.

In order to achieve the above object, the hair treatment agent of the present invention is characterized by containing at least a reducing agent, a dicarboxylic acid or a salt thereof, and a diacylglutamic acid lysine salt.

(Diacylglutamic acid lysine salt)
Moreover, the treatment agent for hair deformation of the present invention contains diacylglutamic acid lysine salt. This diacylglutamic acid lysine salt is intended to improve the smoothness and flexibility of the finished hair.

Examples of diacylglutamic acid lysine salts include sodium lysine dilauroylglutamic acid and the like. In addition, these diacylglutamic acid lysine salts can be used individually or in combination of 2 or more types.

In the present invention, the amount of the diacylglutamic acid lysine salt to be added to the entire hair-modifying treatment agent is not particularly limited, and can be, for example, 0.01 to 2.0% by mass.

As described above, the treatment agent for hair transformation of the present invention contains a reducing agent, and by using a dicarboxylic acid or a salt thereof and a lysine diacylglutamic acid in combination, it is possible to treat hair in advance when performing hair transformation treatment. Without the use of agents, it is possible to uniformly transform the hair in the damaged part often seen at the tip of the hair and in the less damaged part near the root of the hair, and the finished hair has a smooth feel and flexibility. can be improved.

(Reaction modifier)
Moreover, the treatment agent for hair deformation of the present invention may contain a reaction modifier. By containing this reaction modifier, it is possible to suppress excessive reaction of the treatment agent for hair deformation, so that the strength of hair deformation can be adjusted to a desired strength.

This reaction modifier is not particularly limited, and may be one that is commonly used in hair cosmetics. Examples include dithiodiglycolic acid or salts thereof, cystamine or salts thereof.

Examples of salts of dithiodiglycolic acid include diammonium dithiodiglycolate. Examples of cystamine salts include cystamine dihydrochloride.

Among these, it is preferable to use dithiodiglycolic acid or a salt thereof from the viewpoint of being excellent in the effect of adjusting the reduction reaction.

Moreover, the amount of dithiodiglycolic acid or a salt thereof added to the entire hair-modifying treatment agent is not particularly limited, and can be, for example, 4.0% by mass or less.

(solvent)
In addition, the solvent (dispersion medium) used in the hair treatment agent of the present invention is not particularly limited, and water is used. It can be contained in water at concentrations that are not harmful.

The form of the hair-modifying treatment agent of the present invention is not limited to a solution, and may be one in which components added as necessary are suspended or emulsified.

(Sequestering agent)
Moreover, the treatment agent for transforming hair of the present invention may contain a sequestering agent. By containing the sequestering agent, it is possible to suppress the problem that the reducing agent reacts with trace metal components and the titer of the reducing agent is lowered, so that the stability of the treatment agent for hair deformation can be obtained. can.

Examples of the sequestering agent include ethylenediaminetetraacetate (edetate), sodium polyphosphate, and phytic acid.

The amount of the metal sealant compounded with respect to the entire hair-modifying treatment agent is preferably 0.01 to 1.0% by mass.

Moreover, the treatment agent for transforming hair of the present invention may contain a pH adjuster. This pH adjuster is not particularly limited as long as it is usually used in hair cosmetics. For example, guanidine carbonate, sodium dihydrogen phosphate, trisodium phosphate, sesquicarbonate, arginine, sodium hydrogen carbonate, sodium carbonate, monoethanolamine, ammonia, 2-amino-2-methyl-1-propanol, sodium hydroxide , tripotassium citrate, trisodium citrate, and diammonium hydrogen phosphate.

(pH)
The pH of the treatment agent for hair deformation of the present invention is set to 6 to 10 by the above-mentioned pH adjuster.

This is because if the pH is less than 6, hair softness may not be obtained, and if the pH is greater than 10, smoothness may not be obtained.

That is, by setting the pH to 6 to 10, a good feeling of finish can be obtained. From the viewpoint of improving these effects, it is preferable to set the pH to 7 to 9.
