Description

  The present invention relates to a hair deformation treatment agent used in hair deformation treatment such as wave formation and curly hair correction, and relates to a first agent having a reducing agent.

  In the hair deformation treatment accompanied by the hair reduction treatment represented by the permanent wave treatment and the straight permanent treatment, the hair is oxidized after the reduction treatment to fix the deformation.

  Here, as the reducing agent used as the main agent of the first agent, for example, thioglycolates such as ammonium thioglycolate and thioglycolic acid monoethanolamine salt, cysteine or its salts are used, For example, treatment agents using ammonium thioglycolate have a strong irritation odor, and when cysteine is used, there is a problem that a hair deformation effect cannot be obtained sufficiently.

  Therefore, as a reducing agent, a hair deformation treatment containing a reducing agent consisting of one or a combination of two or more selected from ammonium thiolactic acid salt, monoethanolamine thiolactic acid salt, isopropanolamine thiolactic acid salt, and thiolactic acid. Agents have been proposed. By using such a reducing agent, hair deformation treatment equivalent to or higher than that of the thioglycolate salt can be obtained, and the hair deformation treatment has less irritating odor than the thioglycolate salt. It is described that an agent can be provided (for example, refer patent document 1).

  In addition, a hair deformation treatment agent containing thioglycerin and thiolactic acid as a reducing agent has been proposed. By using such a treatment agent, a predetermined condition (relative humidity is 80 to 100%). In hair treatment at a temperature of 20 to 60 ° C. (water vapor), it is described that a hair deformation treatment agent that suppresses hair damage and has an excellent hair deformation effect can be provided (for example, Patent Document 2).

Japanese Patent No. 3261690 Japanese Patent Laying-Open No. 2015-78143

  However, although the hair deformation treatment agent described in the above-mentioned patent document is excellent in hair deformation effect, it is difficult to adjust the speed of the reduction treatment with the reducing agent, so the strength of hair deformation (curl strength) It was difficult to adjust to a desired strength.

  Therefore, the present invention has been made in view of the above problems, and a hair deformation treatment agent capable of sufficiently obtaining the effect of hair deformation and adjusting the strength of hair deformation to a desired strength. The purpose is to provide.

  In order to achieve the above object, the hair deformation treating agent of the present invention comprises 1.0 to 6.0% by mass of thiolactic acid or a salt thereof, 0.3 to 5.0% by mass of thioglycerin, and dithiol. It contains diglycolic acid or a salt thereof.

  According to the present invention, the effect of hair deformation can be sufficiently obtained, and the strength of hair deformation can be adjusted to a desired strength.

  Hereinafter, a preferred embodiment of the present invention will be described. In addition, this invention is not limited to the following embodiment, In the range which does not change the summary of this invention, it can change suitably and can apply.

  The hair deformation treatment agent of the present invention is used as a first agent containing a reducing agent in hair deformation treatment. Here, “hair deformation treatment” refers to treatment involving reduction of cystine bonds in hair, such as permanent wave treatment or straight permanent treatment.

  The treatment agent for deforming hair of the present invention contains thiolactic acid or a salt thereof and thioglycerin as a reducing agent as a main ingredient.

  Examples of thiolactic acid salts include ammonium thiolactic acid, thiolactic acid monoethanolamine salt, and thiolactic acid isopropanolamine salt.

  Moreover, in this invention, the compounding quantity of the thiolactic acid or its salts with respect to the whole hair deformation treatment agent is 1.0-6.0 mass%, Furthermore, the compounding quantity of the thioglycerin with respect to the whole hair deformation treatment agent is It is characterized in that it is 0.3 to 5.0 mass%.

  This is because if thiolactic acid or a salt thereof is less than 1.0% by mass, the hair deformation effect is low, and the curl sustaining effect may not be sufficiently obtained. If it is more than 6.0% by mass, it is due to an excessive reduction effect. This is because the deformation effect (sag of waves) and the texture (curl elasticity) may be reduced due to damage.

  When the thioglycerin content is less than 0.3% by mass, the hair deformation effect is low. This is because there is a possibility that a decrease in slipping) or curling due to the weight specific to thioglycerin may occur.

  That is, a high hair deformation effect can be obtained by setting the amount of thiolactic acid or a salt thereof to 1.0 to 6.0% by mass and further the amount of thioglycerin to 0.3 to 5.0% by mass. In addition to improving the elasticity of the curl, it is possible to obtain an effect that is soft and slippery.

  Further, in the present invention, by using thiolactic acid or a salt thereof, it is possible to improve the feeling of elasticity in the finished hair. By using thioglycerin, the finished hair has a moist feeling and softness. Can be improved.

(Reaction modifier)
Here, the treatment agent for hair deformation of the present invention is characterized in that it contains a reaction modifier. And by containing this reaction regulator, since the excessive reaction of a hair deformation treating agent can be suppressed, it becomes possible to adjust the strength of hair deformation to desired strength.

  This reaction modifier is not particularly limited and may be any one that is usually used for hair cosmetics. Examples thereof include dithiodiglycolic acid or a salt thereof, cystamine or a salt thereof.

  Examples of dithiodiglycolic acid salts include diammonium dithiodiglycolate.

  Examples of cystamine salts include cystamine dihydrochloride.

  Among these, it is preferable to use dithiodiglycolic acid or its salt from a viewpoint that it is excellent in the adjustment effect with respect to a reductive reaction.

  Moreover, it is preferable that the compounding quantity of dithiodiglycolic acid or its salts with respect to the whole treatment agent for hair deformation is 0.01-1.0 mass%.

  When the amount is less than 0.01% by mass, the reaction adjustment (suppression) effect may not be sufficiently obtained. When the amount is more than 1.0% by mass, the reduction reaction may not be sufficiently obtained, or the reduction reaction may occur. This is because it may take a long time (reduction reaction speed decreases).

(solvent)
The solvent (dispersion medium) used in the hair deformation treatment agent of the present invention is not particularly limited, and water is used. If necessary, an organic solvent such as ethanol or isopropanol is contacted with the human body. However, it may be contained in water at a harmless concentration.

  In addition, the aspect of the treatment agent for hair deformation of this invention is not limited to a solution, The component added as needed may be suspended or emulsified.

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

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

  In addition, it is preferable that the compounding quantity of the metal sealing agent with respect to the whole processing agent for hair deformation is 0.01-0.2 mass%.

(PH adjuster)
Moreover, the treatment agent for hair deformation of the present invention may contain a pH adjuster. This pH adjuster is not specifically limited, What is necessary is just normally used for hair cosmetics. For example, guanidine carbonate, sodium dihydrogen phosphate, trisodium phosphate, sesquicarbonate, arginine, sodium bicarbonate, sodium carbonate, monoethanolamine, ammonia, 2-amino-2-methyl-1-propanol, sodium hydroxide , Tripotassium citrate, trisodium citrate, and diammonium hydrogen phosphate.

  Of these, guanidine carbonate is preferably used from the viewpoint of high affinity for hair and high hair deformation effects.

  Moreover, it is preferable that the compounding quantity of the guanidine carbonate with respect to the whole processing agent for hair deformation is 0.01-1.0 mass%.

  This is because if the amount is less than 0.01% by mass, the pH adjusting function may not be sufficiently obtained, and if it is more than 1.0% by mass, the hair may be damaged.

(PH)
The hair deformation treatment agent of the present invention has a pH of 6 to 10 by the pH adjuster.

  This is because when the pH is less than 6, the softness of the hair may not be obtained, and when the pH is greater than 10, a slipperiness may not be obtained.

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

(Preservative)
Moreover, the hair deformation treating agent of the present invention may contain a preservative. By containing a preservative, the stability of the hair deformation treating agent can be obtained.

  Examples of the preservative include benzoic acid, sodium benzoate, salicylic acid, dehydroacetic acid, sodium dehydroacetate, paraben, phenoxyethanol and the like.

  In addition, it is preferable that the compounding quantity of the preservative with respect to the whole treatment agent for hair deformation is 0.01-0.3 mass%.
