Description

  The present invention relates to a hair treatment agent.

  In recent years, hair cosmetics have been expected to have a conditioning effect that can impart smoothness and unity to hair. A technique for imparting smoothness, unity, etc. to hair by blending a cationic polymer or a fatty acid has already been reported. For example, Patent Document 1 discloses a hair cosmetic containing a specific cationic polymer and a cationic compound, which can be uniformly applied to hair, has a good feeling of use, and has a high conditioning effect. However, these effects were poor in sustainability, and smoothness and unity disappeared by the next day's hair washing. Moreover, when the blending amount of the cationic polymer is increased in order to increase the duration of the conditioning effect, there is a problem that the hair feels sticky during rinsing, the hair becomes difficult to align after drying, and a heavy feel remains.

  On the other hand, in Patent Document 2, by combining a specific cationic polymer and a specific branched fatty acid, while maintaining the conditioning effect such as smoothness and unity after drying, the hair can be easily aligned, and a cooler feeling can be achieved. It is disclosed that a pleasant feel can be continuously obtained until the next day's hair washing. Patent Document 3 discloses that a water-insoluble complex is formed between a specific cationic polymer and a specific mixed fatty acid, and by combining silicones, the smoothness that lasts from immediately after the treatment to the next hair wash. A wash-out type hair cosmetic composition that provides a unity is disclosed.

  By the way, sleeping is a phenomenon in which hair is shaped into an undesired shape due to external force applied to the hair from bedclothes or the like at bedtime, and is a troublesome phenomenon that many people feel in daily life. When we lie down, wet the hair with water or a hair styling agent, or humidify it to cut hydrogen bonds existing inside the hair, then dry it with a dryer or hair iron, The operation of reforming hydrogen bonds in a more preferable shape is necessary. In addition to being cumbersome, this operation takes a lot of time and effort. For busy modern people, it is difficult to fall asleep and a hair treatment agent that maintains a good hair feel until the next shampoo is required. It was done.

  However, Patent Documents 1 to 3 disclose the conditioning effect and its duration, but do not suggest the effect of making it difficult for the hair to lie down, and the effect is insufficient.

  Therefore, in addition to making the hair less likely to fall asleep, the present invention suppresses stickiness during rinsing, imparts smoothness to the hair, and maintains the unity and smoothness of the hair until the next shampoo.

  Step A is preferably performed on wet hair after rinsing with a hair cleanser. In addition, from the viewpoint of no stickiness during rinsing and smoothness during rinsing, step B is preferably performed after step A without rinsing the agent A on the hair with water.

  After step B, it may be washed away with water, preferably warm water.

Examples 1-5, Comparative Examples 1-7
Hair treatment agents A and B shown in Table 1 were prepared according to a conventional method. Various evaluations shown below were performed using one or both of these hair treatment agents.

Non-sticky / smooth hair color at the time of rinsing A hair tress was prepared using 20 g (about 30 cm in length) of hair of a person who used hair color four times a year. The hair tress was washed with 1 g of the following model shampoo, and then rinsed with warm water at 40 ° C. for 30 seconds while passing a finger through the hair. Next, 1 g of agent A was applied and thoroughly blended into the entire hair, and then rinsed with warm water at 40 ° C. for 30 seconds, and was subjected to sensory evaluation from the viewpoint of stickiness and smoothness. For Example 4 and Comparative Examples 3 and 5, after applying agent A and thoroughly blending into the hair, 1 g of agent B was applied without washing off and thoroughly blended into the entire hair, then 40 ° C. Sensory evaluation was performed from the viewpoint of stickiness and smoothness while rinsing with warm water for 30 seconds. For Comparative Example 7, after washing the hair traces with 1 g of model shampoo and rinsing, 1 g of B agent was applied without applying A agent, and the hair was fully acclimated. Sensory evaluation was performed from the viewpoint of stickiness and smoothness while rinsing with warm water for 30 seconds.
For the non-stickiness at the time of rinsing, it is “not sticky” / “can't say either” / “sticky”, and for the smoothness at the time of rinsing, “smooth” / “can't say” / “not smooth” Each was selected alternatively.
The evaluation was performed by seven panelists, and the number of panelists who answered “not sticky” / “neither” / “sticky”, “smooth” / “neither” / “not smooth” in order. .

The duration of the unity, do towel dry the hair tresses of after evaluating the name of-smoothness of the stickiness at the time of the smoothness of the sustained rinse, was sufficiently dried in the dryer, one day under laboratory conditions (24 hours) After hanging and letting it stand, it united and sensory evaluation was performed from the viewpoint of smoothness.
For the sustainability of the unit, select from “Summarize” / “Neither” or “Not manage”. For the sustainability of smoothness, select from “Smooth” / “Neither” or “Not smooth”. I was selected.
The evaluation is performed by 7 panelists, and the number of panelists who answered “Summarize” / “Neutral” / “Smooth”, “Smooth” / “Neutral” / “Not smooth” is shown in order. .

As a wig for evaluation of difficulty in falling asleep , a Chinese straight hair wig (manufactured by Beaulux) cut into short hair was used. After washing with 3 g of model shampoo, it was rinsed with warm water at 40 ° C. for 30 seconds while passing a finger through the hair. Next, 3 g of agent A was applied, and it was blended for 30 seconds while passing a finger through the hair, and then rinsed away with warm water at 40 ° C. for 30 seconds while passing the finger through the hair. For Example 4 and Comparative Examples 3 and 5, after applying agent A and thoroughly blending into the hair, 3 g of agent B was applied without washing away and thoroughly blended into the entire hair, then 40 ° C. Rinse with warm water for 30 seconds while passing a finger through the hair. In Comparative Example 7, the hair was washed with 3 g of model shampoo, rinsed, and then applied with 3 g of B agent without applying the A agent. After thoroughly blending into the entire hair, warm water at 40 ° C. Rinse for 30 seconds.
Thereafter, excess moisture was wiped off with a towel, and the wig after drying for 3 minutes with a dryer (manufacturer; TESCOM, model number: NB1902) was used for evaluation. Two towels (cotton, length 80 cm x width 34 cm) with the long side folded in half from the middle are stacked on a hot plate (CAMAG, TLC PLATE HEATER) set and heated to 35 ° C in advance. Then, a non-woven fabric (20 cm long × 14 cm wide) containing 5 g of moisture was spread between the towels, and a pseudo pillow having a constant moisture was produced. Next, after placing the evaluation wig after treatment with the above-mentioned hair cleaning composition on a towel (pseudo pillow) on its back, move it 10 cm while dragging it toward the neck of the wig to evaluate the difficulty of lying. Then, it was left as it was for 1 hour.
Then, after waking up, the hair part with a lie down was patted 3 times, and a hand comb was passed at a speed of 20 cm / sec.
As for the state after stroking, seven panelists were allowed to select one of “not easy to fall asleep” / “can not say either” / “easy to fall asleep”. The number of panelists who answered “It is difficult to sleep” / “I can't say either” / “I am easy to sleep” is shown in order.
