Description

  The present invention relates to a liquid hair treatment agent.

  As a hair treatment agent, conventionally, an aqueous hair treatment composition containing a hydrolyzed protein is known (Japanese Patent Publication No. 2005-513029). This aqueous hair treatment composition is formulated with a hydrolyzed protein for the purpose of preventing hair damage.

  However, the above-mentioned aqueous hair treatment composition may be able to prevent damage to the hair, but by adding hydrolyzed protein, the finger passage and comb passage after application are deteriorated, and the hair is not caught. It is likely to occur. In particular, wet hair after shampooing and the like tends to expose the hair itself (keratin) by washing the surface of the hair. Therefore, when hydrolyzed protein is attached to wet hair, it becomes more likely to be caught.

JP 2005-513029 gazette

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a liquid hair treatment agent that can suppress catching due to deterioration of finger passage and comb passage.

  The invention made to solve the above problems is a liquid hair treatment agent containing a hydrolyzed protein and an anionic compound.

  According to the liquid hair treatment agent, in addition to the hydrolyzed protein, an anionic compound is blended. Therefore, the finger hair and combing after application of the liquid hair treatment agent are prevented from deteriorating and the catching is suppressed. Can do.

  The liquid hair treatment agent may contain at least one of an anionic surfactant and dilauroylglutamic acid lysine salt as the anionic compound. By blending such an anionic compound in the liquid hair treatment agent, it is excellent in improving the fingering and combing after application of the liquid hair treatment agent.

  The viscosity of the liquid hair treatment agent is, for example, 100 mPa · s or less. The fingering and combing by adding hydrolyzed protein generally tends to deteriorate as the viscosity of the liquid hair treatment agent is low, but since the liquid hair treatment agent contains an anionic compound, Deterioration can be suppressed.

  As a compounding quantity of the anionic compound in the said liquid hair treatment agent, 1 mass% or less is preferable. Thus, the foaming by the said liquid hair treatment agent can be suppressed because the compounding quantity of an anionic compound is 1 mass% or less.

  As a compounding quantity of the said hydrolyzed protein, it is 10 mass% or less, for example.

  Water is further added to the liquid hair treatment agent, and the amount of the water is, for example, 85% by mass or more. Thus, by setting the water content in the above range, a liquid hair treatment agent having a low viscosity is obtained, but the above-described deterioration of fingering and combing due to the low viscosity is also suppressed by the addition of an anionic compound. it can.

  ADVANTAGE OF THE INVENTION According to this invention, the liquid hair treatment agent which can suppress the catch by the deterioration of a finger passage or a comb passage is provided.

  The liquid hair treatment agent of the present invention is a mixture of hydrolyzed protein and an anionic compound. The liquid hair treatment agent may contain a polyhydric alcohol and may contain other optional components as long as the effects of the present invention are not impaired. Hereinafter, these components will be described in detail.

[PH]
The pH of the liquid hair treatment agent is preferably 4 or more and 8 or less, and more preferably 4 or more and 7 or less. When the pH of the liquid hair treatment agent exceeds 8, it is not preferable because the hair swells when the liquid hair treatment agent is applied to the hair.

[Dosage form, viscosity, etc.]
It does not specifically limit as a dosage form of the said liquid hair treatment agent, It determines according to the use etc. of the said liquid hair treatment agent. When the dosage form is liquid or mist, the amount of water in the liquid hair treatment agent is, for example, 85% by mass or more.

[Usage]
The liquid hair treatment agent is used in various hair treatment agents such as styling agents and hair care agents by appropriately blending optional components. Here, the “styling agent” is a hair treatment agent used for temporarily holding a hairstyle. “Hair care agent” is a hair treatment agent used for the care and care of hair, for example, rinse, conditioner, treatment (for example, non-washing treatment, flushing treatment, multi-component treatment) , Perm pre-treatments, perm post-treatments, coloring pre-treatments, coloring post-treatments, bleach pre-treatments, bleach pre-treatments, bleach Treatment for post-treatment).

  The liquid hair treatment agent is preferably used in a mode different from shampoo, and is preferably used as a treatment, particularly as wet hair treatment after shampooing. In this way, wet hair after shampoo is in a state where finger passage and comb passage are likely to deteriorate, so the liquid hair treatment agent with suppressed catching is preferably used as a treatment applied to wet hair. Can do.

  As described above, the liquid hair treatment agent can be used as one component of a multi-drug treatment. For example, when the liquid hair treatment agent is used as the first agent of a multi-drug treatment in which a plurality of agents are applied without being washed away, the second and subsequent agents may be used if the finger or comb after application of the first agent is bad. Since the applicability when applying the hair treatment agent is deteriorated and a sufficient treatment effect may not be obtained, the liquid hair treatment agent with suppressed catching is suitable as the first agent of the multi-drug treatment. Can be used.

  Hereinafter, although the said liquid hair treatment agent is demonstrated by an Example, this invention is not limited to a following example.

<Evaluation>
About the liquid hair treatment agent of Examples 1-3, Comparative Examples 1-2, and a reference example, suppression of a catch and film | membrane feeling were evaluated by the method demonstrated below. The evaluation results are shown in Table 1.

[Evaluation of catch suppression]
As for catching, a hair bundle having a coloring history was shampooed, a liquid hair treatment agent was applied to the hair bundle, and then, the finger bundle and comb comb were evaluated. After the evaluation, the hair bundle was washed with water. In this evaluation, the catch when using the liquid hair treatment agent of Comparative Example 2 was used as a reference, and the following evaluation was made as a comparison with this reference.

◯: There is no catch than the standard −: The standard is the same as the standard ×: The standard is caught

[Evaluation of film feeling]
The feeling of the film was evaluated as a feeling that a film of the composition applied to the hair surface was formed at the time of evaluation according to the finger in suppressing the catch. In this evaluation, the liquid hair treatment agent of Reference Example was used as a reference, and the following evaluation was made as a comparison with this reference.

◯: There is a feeling of film than the standard −: A feeling of film equivalent to the standard ×: There is no feeling of film than the standard

  As is clear from Table 1, the results were obtained that the liquid hair treatment agents of Examples 1 to 3 were able to suppress catching compared to the liquid hair treatment agents of Comparative Examples 1 and 2. Moreover, the result was obtained that the liquid hair treatment agents of Examples 1 to 3 had a film feeling as compared with Comparative Example 2 and Reference Example. Therefore, by blending with the anionic compound together with the hydrolyzed protein, it is possible to suppress the catch compared to the case where the nonionic surfactant is blended and compared to the case where the anionic compound is not blended. Further, by blending the anionic compound together with the hydrolyzed protein, a film feeling can be obtained as compared with the case where the cationic surfactant is blended and compared with the case where the anionic compound is not blended.
