Description

  The present invention relates to a hair treatment composition. More specifically, the present invention relates to a hair treatment composition that can be applied separately for each part of hair.

  The two-component hair treatment composition for forming a wave design and a straight design on the hair is oxidized to a desired shape after breaking the disulfide bond of the hair with the first agent containing a reducing agent and an alkaline agent. The disulfide bond of hair is recombined with the second agent containing the agent.

  Since the first agent breaks the disulfide bond of the hair, it causes damage to the hair. Therefore, it is possible to select the first agent according to the degree of damage to the hair so that the finish of the hair treatment is good and the degree of damage to the hair can remain in a state that can withstand the chemical treatment after the next time. It is very important. However, since the damage state of normal hair gradually increases as it moves away from the root, it is difficult to respond to different damage levels for each part of hair by using only one kind of drug. Under such circumstances, a method that is frequently employed in hair treatment treatment is a method in which a plurality of first agents having different strengths are used to coat different portions with different degrees of hair damage. That is, a stronger first agent is applied to the root with relatively little damage, and a weaker first agent is applied to the damaged hair end.

  It is required that the applied part is clearly understood and that it does not hinder the extension with a brush while remaining in the place where the first agent is applied and does not sag or flow. It is done. However, the conventional first agent, which is a composition obtained by adding a component that reduces damage to hair to a higher alcohol that adjusts the viscosity, is gradually transparent when applied to hair that is normally treated in a wet state. The applied part is not clear, and the hardness that can prevent dripping and the good elongation when stretched with a brush have not been achieved (see, for example, Patent Document 1 and Patent Document 2).

Moreover, the hair treated with the hair treatment composition of the present invention has a soft and moist texture, and is well-organized up to the ends. Furthermore, the stability over time of the emulsified state is good.

Hereinafter, the present invention will be specifically described.
The hair treatment composition of the present invention is a hair treatment composition containing a reducing agent and an alkaline agent, and comprises 3.0 to 5.5% by weight of a higher alcohol (A) and 2.0 to 2.0% of a polyol (B). 5.0 wt%, liquid oil (C) 2.0-5.0 wt%, nonionic surfactant (D) 0.2-5.0 wt% and cationic surfactant (E) 0.5 The weight of the component (B) / the weight of the component (C) is 0.7 to 1.5, the weight of the component (A) / {the weight of the component (B) + (C ) Component weight} is 0.3 to 1.0, and the HLB of component (D) is 5.5 to 12.0.

1. Hair Treatment Composition (1) Reducing Agent The reducing agent used in the composition of the present invention can include, without limitation, reducing agents that can be used for ordinary permanent wave treatment or curling treatment, but thioglycolic acid and Derivatives thereof, thioglycolates such as ammonium thioglycolate, sodium thioglycolate, monoethanolamine thioglycolate, cysteine and derivatives and salts thereof, N-acetyl-L-cysteine, homocysteine, thiolactic acid, thiomalic acid, etc. Mercaptocarboxylic acids, mercaptoalcohols such as thioglycerol, mercaptocarboxylic esters such as glycerol monothioglycolate and glycerol monothiolactate, cysteamine and its derivatives and salts, cysteine amide, etc. Mercapto compounds, sulfite, ammonium sulfite, sulfite such as sodium sulfite, ammonium bisulfite, and bisulfite and butyrolactone thiol such as sodium bisulfite. Examples of the salts include hydrochloride, citrate, hydrobromide, acetate, ammonium salt, monoethanolamine salt and the like.
The amount of the reducing agent in the composition of the present invention is not particularly limited, and is appropriately selected depending on the kind of the reducing agent and the pH of the composition.

(2) Alkaline agent The alkali agent used in the composition of the present invention can include, without limitation, an alkali agent that can be used for ordinary permanent wave treatment or curling treatment, but ammonia, monoethanolamine, diethanolamine, 2 -Amino-2-methyl-1-propanol, carbonates such as ammonium bicarbonate or sodium bicarbonate, arginine and the like.

(3) Higher alcohol (A)
The higher alcohol as the component (A) is not particularly limited as long as it is an alcohol having one hydroxyl group and having a large number of carbon atoms, and examples thereof include alcohols having one hydroxyl group and having 14 to 22 carbon atoms. Includes lauryl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, cetostearyl alcohol, oleyl alcohol, myristyl alcohol, hexyldecanol and the like, more preferably cetyl alcohol and cetostearyl alcohol. These may be used alone or in combination of two or more.

  (A) The compounding quantity of a component is 3.0 to 5.5 weight% with respect to 100 weight% of compositions for hair treatment, and 3.5 to 4.5 weight% is preferable. When the blending amount of the component (A) is less than 3.0% by weight, the viscosity of the composition is too low and the composition applied to the hair drips, and cannot be emulsified, or even if emulsified, stability over time cannot be ensured. . If it exceeds 5.5% by weight, the viscosity becomes too high and the composition becomes hard, so that it takes time to take out from the container and work with a brush, and the workability is poor. On the other hand, when the blending amount of the component (A) is in the above range, the viscosity of the composition can be appropriately maintained, and when it is within the preferable range, the viscosity can be more appropriately maintained.

(4) Polyol (B)
The polyol as the component (B) is not particularly limited as long as it is an alcohol having two or more hydroxyl groups, and examples thereof include propylene glycol, dipropylene glycol, 1,3-butylene glycol, glycerin and sorbitol. Includes propylene glycol. These may be used alone or in combination of two or more.

  (B) The compounding quantity of a component is 2.0-5.0 weight% with respect to 100 weight% of compositions for hair treatment. When the blending amount of the component (B) is less than 2.0% by weight, a sufficient water retention effect cannot be obtained, and the moisture in the hair flows out due to softening and swelling of the hair by the alkaline agent, and the hair is soft. The texture of the hair and the clumping of the hair become worse. If it exceeds 5.0% by weight, the transparency of the polyol will affect the appearance of emulsification, and it will be difficult to obtain the effect of white residue when applied to the hair. On the other hand, when the blending amount of the component (B) is in the above range, the effect of water retention can be imparted to the hair, and the effect of remaining white can be obtained.

(5) Liquid oil (C)
The liquid oil of component (C) is not particularly limited as long as it is a liquid oil at 25 ° C. other than components (A) and (B), but liquid paraffin, isododecane, liquid lanolin, isopropyl palmitate, myristic acid Isopropyl, octyldodecyl myristate, cetyl ethylhexanoate, isostearyl isostearate, diisopropyl dilinoleate, isononyl isononanoate, glyceryl tri-2-ethylhexanoate, rosehip oil, avocado oil, jojoba oil, olive oil, macadamian nut oil, Castor oil and the like, preferably liquid paraffin, and isopropyl myristate. These may be used alone or in combination of two or more.

  (C) The compounding quantity of a component is 2.0 to 5.0 weight% with respect to 100 weight% of compositions for hair treatment. When the blending amount of the component (C) is less than 2.0% by weight, the oil content is insufficient and the hair becomes textured. If it exceeds 5.0% by weight, a squeaky sensation peculiar to an oil component is generated, and it is difficult to obtain a soft texture of the hair. On the other hand, when the blending amount of the component (C) is in the above range, the hair has a soft texture and is well organized.

  When a large amount of solid oil was blended in the hair treatment composition at 25 ° C. in place of the component (C) or together with the component (C), it was found that the white residue was remarkable. However, if the amount of solid oil in the hair treatment composition is large, the looseness of the hair becomes worse when the first agent is poured from the hair and dried. Due to the necessity of performing the treatment and the length of the treatment, the thermal damage was excessive. In addition, due to excessive heat treatment and solid oil remaining in the hair, the hair texture has a hard finish. Therefore, the hair treatment composition of the present invention preferably contains no solid oil or less than 0.1% by weight.

(6) Nonionic surfactant (D)
Although it does not restrict | limit especially as a nonionic surfactant of (D) component, POE alkyl ethers, such as POE (2) stearyl ether, POE (30) stearyl ether, POE (6) oleyl ether POE (20) oleyl ether, etc. , Polyoxyethylene polyoxypropylene cetyl ether (1E.O.)

When the blending amount of the component (D) is less than 0.2% by weight, the hair treatment composition is not stable, so the temporal stability is poor. Deteriorate.

  (H) HLB of a component is 5.5-12.0, and 5.5-11.0 is preferable. The component (D) HLB means the nonionic surfactant HLB when the component (D) is a single nonionic surfactant, and the component (D) has two or more types of nonionic surfactants. When composed of a mixture of surfactants, it refers to the HLB of the mixture.

  When the HLB of the component (D) is less than 5.5, emulsification cannot be achieved sufficiently and the composition containing the reducing agent cannot be kept stable. On the other hand, when the HLB exceeds 12.0, the effect of white residue cannot be obtained, the composition of the hair after composition distribution is poor, and the final finish of the hair is not soft and moist. On the other hand, when the HLB is in the above range, after applying the hair treatment composition to the hair, the white-remaining effect is maintained, the hair treatment composition is stable, the hair is cohered, and the texture is soft and moist. Become.

In this specification, when the component (D) is a single nonionic surfactant, the HLB of the component (D) was determined by the Kawakami method.
In this specification, when (D) component contains 2 or more types of nonionic surfactant, HLB of (D) component was calculated | required with the following method (The HLB value of each nonionic surfactant is Kawakami. This is a value obtained by the method, and a case where two kinds are mixed is taken as an example).
HLBαβ of component (D) containing nonionic surfactant α having an HLB value of HLBα of x wt% and nonionic surfactant β having an HLB value of HLBβ of 100-x wt% is represented by the following formula.
HLBαβ = HLBα (x / 100) + HLBβ {(100−x) / 100}

These may be used alone or in combination of two or more.

  (E) The compounding quantity of a component is 0.5 to 3.0 weight% with respect to 100 weight% of compositions for hair treatment, and 1.0 to 2.5 weight% is preferable. When the blending amount of the component (E) is less than 0.5% by weight, it is difficult to maintain the stability over time, and in the final finish of the hair, the unity to the end of the hair is deteriorated. If it exceeds 3.0% by weight, it is difficult to maintain stability over time, and stickiness occurs in the final finish of the hair, and a soft texture cannot be obtained. On the other hand, when the amount of component (E) is in the above range, the cream state can be kept stable.

  If the value of (B) component weight / (C) component weight is less than 0.7, (C) component will have an effect of imparting hardness to the hair, so the finish of the hair is soft. It can not be. If it exceeds 1.5, the transparency of the composition increases, the effect of white residue on the hair cannot be obtained, the hair feel is refreshed, and the damage due to hair treatment is easily noticeable Become. On the other hand, when the value of the weight of the component (B) / weight of the component (C) is in the above range, the effect of remaining white and the effect of making the hair finish soft and moist can be achieved. .

(10) Weight ratio of component (A) to the total weight of component (B) and component (C) The hair treatment composition of the present invention comprises the component (A) relative to the total weight of component (B) and component (C). The weight ratio of (A) component / (B) component weight + (C) component weight} is 0.3 to 1.0, 0.3 to 0.7. Is preferred.

  When the value of (A) component weight / {(B) component weight + (C) component weight} is in the above range, and the amount of (A) component is within the range of the present invention, the composition is thixotropic. Showing gender. That is, when a brush force is applied to the composition, the composition becomes fluid and the operation of applying the composition with the brush can be easily performed, while the application is completed and the brush force is removed from the composition. Then, the composition loses its fluidity and remains at the place where it is applied. On the other hand, when the value of the weight of the component (A) / {weight of the component (B) + weight of the component (C)} is less than 0.3, the composition applied to the hair drips. When it exceeds 0, the elongation of the composition becomes poor, and when the brush is applied, the composition cannot be applied to the hair tip with a single touch, and workability is lowered.

  (11) The pH of the hair treatment composition of the present invention is preferably 7 to 9.5, and more preferably 8.5 to 9.2. The pH is determined from the viewpoint of good design formation.
