Description

  The present invention is used after permanent wave treatment or hair straightening treatment to recover hair damage, and well suppresses the swelling property of the hair based on the damage to maintain hair strength. It is related with the post-treatment agent for permanent wave or curly hair straightening which suppresses the unpleasant smell after permanent wave processing or curly hair straightening treatment.

  Conventionally, permanent wave agents and hair straighteners are widely used as means for changing the shape of hair. It is possible to change the shape of the hair by performing permanent wave and straightening operations, but at the same time, the inside or surface of the hair is damaged by the influence of the permanent wave agent or straightening agent, and the hair becomes water. It becomes easy to swell by sucking. As a result, protein inside the hair flows out and the mechanical strength of the hair is lowered, and it appears functionally as a deterioration of touch such as deterioration of hair slippage and dryness. Moreover, the ease of swelling of the hair also causes a problem that the sustainability of the straight effect and the wave effect is lowered.

  Moreover, as a reducing agent to be blended in the first agent of permanent wave agent or hair straightener, thioglycolic acid or a salt thereof, cysteine or a salt thereof, acetylcysteine or a salt thereof, thiolactic acid or a salt thereof, cysteamine or a salt thereof Organic thiol compounds such as thioglycerol and glyceryl thioglycolate are used. These organic thiol compounds not only cleave disulfide bonds in the hair, but also react with sulfur compounds such as cystine in the hair, or cause a chemical reaction with the organic thiol compound itself to produce low molecular sulfur compounds. Let The mercaptan odor and hydrogen sulfide odor of these low-molecular sulfur compounds are peculiar unpleasant odors called permanent odors, which remain on the hair for several weeks after the treatment, and are desorbed and diffused during hair washing and sweating. There was also the problem of giving extreme discomfort.

  For the above problem, for example, as seen in Patent Document 1 and Patent Document 2 below, silicone or protein hydrolyzate is used as a treatment agent for the purpose of preventing damage or improving touch by permanent wave or straightening treatment. Proposals have been made of adding cationized cellulose or the like, or blending silicone or protein hydrolyzate as a pre-treatment agent or post-treatment agent for permanents.

JP-A-10-87447 JP, 2000-191447, A For example, as can be seen in Patent Document 3 and Patent Document 4 below, unpleasant odors that occur during permanent treatment or hair straightening treatment are those after permanent wave treatment or hair straightening. There have been proposed treatment agents that suppress an unpleasant odor by applying an acidic aftertreatment agent to treated hair, and deodorizers containing a specific polymer.

JP-A-3-271214 JP 2004-339181 A

  However, if a large amount of silicones is added to the permanent wave agent or hair straightener, it will cause oil stains when wet and a decrease in product stability. Could not be granted. Moreover, although protein hydrolyzate is useful for preventing damage to some extent, its effect is not fully satisfactory, and there has been a problem that wave power is lowered or sticky when used in large quantities. Although cationized cellulose is adsorbed on the hair surface and has a high effect of reducing the squeaky sensation during plain rinsing, there is a problem that it becomes crisp and firm when dry.

  Moreover, although the above method is temporarily effective, the sustainability has not reached a sufficiently satisfactory level.

  That is, the present situation is that it is difficult to obtain a sufficient damage prevention effect or feel improvement effect by simply adding silicone or a protein hydrolyzate to a permanent wave agent, a hair straightener, or a treatment agent before and after the permanent wave agent.

  On the other hand, conventional treatment agents and deodorizers that suppress unpleasant odors are not yet sufficiently satisfactory as an unpleasant odor suppressing effect, and also produce an unpleasant feel such as a feeling of stiffness or squeaky on the hair, resulting in a finished feeling. There was a problem of being damaged.

  The present invention is used after permanent wave treatment or curly hair straightening treatment to recover hair damage, and also suppresses the swelling property of hair based on the damage to maintain the wave effect or straight effect of hair, and the permanent wave treatment Alternatively, an object is to provide a post-treatment agent for permanent wave or hair straightening that suppresses an unpleasant odor after hair straightening treatment.

  In the post-treatment composition of the first invention, as a second effect, the residual unpleasant odor based on the low molecular sulfur compound after the permanent wave treatment or the hair straightening treatment is remarkably suppressed. The reason why such a second effect is obtained is not yet clear, but the low-molecular sulfur compound that is the source of the permanent unpleasant odor generated by the treatment of the permanent wave agent or the hair straightener is the It can be considered that the chemical reaction with the ester compound is changed to a compound with less odor.

<Evaluation of straight effect>
A bundle of 3 g curly hair (20 cm in length) of a Japanese woman in her twenties who has not been chemically treated with a perm, hair color or the like was used as a measurement hair bundle. The hair bundle was lightly moistened with warm water, and both ends of the hair bundle were fixed on the panel. Thereafter, 3 g of the first hair straightening agent 1 was applied to the entire hair bundle and left at 37 ° C. for 20 minutes. Next, after thoroughly washing the hair bundle with water and drying with towel, 3 g of the second curly hair straightening agent 2 was applied, left at room temperature for 20 minutes, and then thoroughly washed with water. Thereafter, towel drying was performed, and 3 g of post-treatment for curly hair correction of Examples 1 to 6 and Comparative Examples 1 to 3 were respectively applied and left at room temperature for 20 minutes. Thereafter, it was washed with water and dried naturally. The hair bundle subjected to the above treatment was visually observed in a natural state, and the straight effect immediately after the treatment was evaluated using Comparative Example 1 as a control. In contrast to Comparative Example 1, “5 points” indicates a very good case, “4 points” indicates a favorable case, “3 points” indicates a case where the case is equivalent to Comparative Example 1, and the case is slightly poor. “2 points” was determined as “1 point”.
<Evaluation of sustainability of straight effect>
Using the hair bundle which evaluated the straight effect including the use of the post-treatment agent for straightening hair according to Examples 1 to 6 and Comparative Examples 1 to 3, the hair was immersed in a 1% by mass sodium lauryl sulfate aqueous solution and 60 ° C. And left for 1 hour (hereinafter, this operation is referred to as an abuse test), then lightly rinsed with water and allowed to dry naturally. The hair bundle before the abuse test and the hair bundle after the abuse test are visually compared, and the durability of the straight effect is “5 points” when it is very good, “4 points” when it is good. The case of “3 points”, the case of slightly bad “2 points”, and the case of bad “1 point”.

In the above evaluation, “(the sustainability of the straight effect) is very good” means that the straight effect before the abuse test was almost completely maintained despite the abuse test. The phrase “is” means that the straight effect before the abuse test was maintained to the extent normally expected after the abuse test as described above.
<Evaluation of hair swelling inhibiting effect>
For the hair subjected to the above-mentioned curly hair straightening treatment (in this case, one having an average diameter of 80 μm ± 2 μm was used), a diameter of the hair was measured when a certain amount of water was dropped to swell the hair. If the degree of hair damage increases, the diameter of the swollen hair increases in proportion to the damage, and this was used to evaluate the degree of hair damage. The hair diameter in water of each of the hair before and after treating the after-treatment agents for straightening hair according to Examples 1 to 6 and Comparative Examples 1 to 3 in the curly hair straightening treatment is measured, The hair swelling inhibition rate (%) was calculated.

Hair swelling inhibition rate (%) = {1- [hair diameter after post-treatment (μm)] / [hair diameter before post-treatment (μm)]} × 100
As can be seen from the above expression of the hair swelling inhibition rate, the higher the ability to inhibit hair swelling in water, the higher the hair swelling inhibition rate. Therefore, these hair swelling inhibition rates were evaluated according to the following evaluation criteria in four stages of “×, ○, Δ, ×”.
(Evaluation criteria)
A: Hair swelling inhibition rate is 10% or more. O: Hair swelling inhibition rate is 5% or more and less than 10%. Δ: Hair swelling inhibition rate is 1% or more and less than 5%. X: Hair swelling inhibition rate is less than 1%. Evaluation of effects>
