Description

The present invention relates to a hair treatment agent.

In recent years, hair cosmetics are expected to have a conditioning effect that can impart smoothness and cohesiveness to hair. Techniques for imparting smoothness and cohesiveness to hair by blending cationic polymers and fatty acids have already been reported. However, these effects were not long-lasting, and by the time the hair was washed the next day, the smoothness and cohesiveness had disappeared. Further, when the blending amount of the cationic polymer is increased in order to enhance the duration of the conditioning effect, there is a problem that the hair becomes sticky at the time of rinsing, the hair becomes difficult to align after drying, and a heavy feeling remains.

On the other hand, in Patent Document 1, by combining one or more cationic polymers and a cationic surfactant, clean, brilliant, smooth and soft hair is obtained, and combing becomes easy. Its good cosmetic properties have been disclosed in cosmetic compositions that last for a long time, even after multiple shampoos. Further, in Patent Document 2, by combining a specific cationic polymer and a specific branched fatty acid, the conditioning effect such as smoothness and cohesiveness after drying is maintained, and the hair is easily aligned and a cool feeling is given. It is disclosed that a comfortable feel can be continuously obtained until the next day's hair washing. Further, in Patent Document 3, a water-insoluble complex is formed between a specific cationic polymer and a specific mixed fatty acid, and further combined with silicones, the hair lasts from immediately after the treatment to the next hair washing. A wash-off type hair cosmetic composition that provides smoothness and cohesiveness is disclosed.

By the way, sleeping is a phenomenon in which the hair is shaped into an undesired shape in terms of appearance by an external force applied to the hair from bedding or the like at bedtime, and is an annoying phenomenon that many people feel in their daily lives. When fixing the nap, the hair is moistened with water or a hair styling product, or moisturized to break the hydrogen bonds inside the hair, and then dried with a dryer or curling iron. The operation of reforming the hydrogen bond in a more preferable shape is required. This operation is generally complicated and takes a lot of time and effort, so for busy modern people, a hair treatment agent that makes it difficult to fall asleep and has a good hair feel until the next hair wash is required. Was being done.

However, although Patent Documents 1 to 3 disclose the conditioning effect and its duration, it does not suggest the effect of making it difficult for the hair to fall asleep, and the effect is also insufficient.

Therefore, the present invention, in addition to making the hair difficult to lie down, suppresses stickiness at the time of rinsing, imparts smoothness to the hair, and maintains the cohesiveness and smoothness of the hair until the next hair washing.

Examples 1-8, Comparative Examples 1-6
The 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.

A hair tress was prepared using 20 g (about 30 cm in length) of human hair that had been used for non-greasy and smooth hair color at the time of rinsing four times a year. This 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 the sensory evaluation was performed from the viewpoint of stickiness and smoothness while rinsing with warm water at 40 ° C. for 30 seconds. In Example 5 and Comparative Example 3, after applying agent A and allowing the hair to be sufficiently blended, 1 g of agent B was applied without rinsing, and the hair was sufficiently blended with warm water at 40 ° C. While rinsing for 30 seconds, sensory evaluation was performed from the viewpoint of stickiness and smoothness. In Comparative Example 6, the hair tress was washed with 1 g of model shampoo, rinsed, and then 1 g of agent B was applied without applying agent A, and the hair was sufficiently blended into the entire hair at 40 ° C. While rinsing with warm water for 30 seconds, sensory evaluation was performed from the viewpoint of stickiness and smoothness.
The non-greasyness during rinsing is "non-greasy" / "neither" / "sticky", and the smoothness during rinsing is "smooth" / "neither" / "not smooth". I let them choose each one.
The evaluation was conducted by 7 panelists, and the number of panelists who answered "not sticky" / "neither" / "sticky", "smooth" / "neither" / "not smooth" is shown in order. ..

Sustaining cohesiveness, maintaining smoothness After evaluating the non-stickiness and smoothness during rinsing, towel dry the hair tress, dry it sufficiently with a dryer, and then 1 day (24 hours) under laboratory conditions. After hanging and letting it stand, sensory evaluation was performed from the viewpoint of cohesiveness and smoothness.
Select from "cohesive" / "neither" / "uncoordinated" for the sustainability of cohesion, and "smooth" / "neither" / "not smooth" for the sustainability of smoothness. I was allowed to make a one-off choice.
The evaluation is performed by 7 panelists, and the number of panelists who answered "cohesive" / "neither" / "uncoordinated", "smooth" / "neither" / "not smooth" is shown in order. ..

Shampoo resistance After washing the hair tress after the above-mentioned durability evaluation with 1 g of model shampoo, sensory evaluation was performed from the viewpoint of smoothness while rinsing with warm water at 40 ° C. for 30 seconds.
The smoothness during rinsing was selected from "smooth" / "neither" / "not smooth". The evaluation is performed by 7 panelists, and the number of panelists who answered "smooth" / "neither" / "not smooth" is shown in order.

As a wig for evaluating the difficulty of sleeping, we used a Chinese straight-haired wig (manufactured by Burax) cut into short hair. After washing with 3 g of model shampoo, the hair 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 the hair was allowed to pass through the hair for 30 seconds, and then rinsed with warm water at 40 ° C. for 30 seconds while passing the finger through the hair. In Example 5 and Comparative Example 3, agent A was applied and thoroughly blended into the hair, then 3 g of agent B was applied without rinsing, and the entire hair was sufficiently blended, and then warm water at 40 ° C. was applied. Rinse through the hair for 30 seconds with your finger. In Comparative Example 6, the hair was washed with 3 g of model shampoo, rinsed, and then 3 g of agent B was applied without applying agent A, and the hair was sufficiently blended with the entire hair, and then warm water at 40 ° C. was applied. Rinse for 30 seconds.
Then, the excess water was wiped off with a towel, and the wig after drying with a dryer (manufacturer; TESCOM, model number: NB1902) for 3 minutes was used for evaluation. Two towels (cotton, length 80 cm x width 34 cm) folded in half from the center are stacked on a hot plate (CAMAG, TLC PLATE HEATER) that has been set and heated to 35 ° C in advance. A non-woven fabric (length 20 cm x width 14 cm) moistened with 5 g of water was spread and sandwiched between towels to prepare a pseudo pillow having a certain amount of water. Next, the evaluation wig after the above-mentioned hair cleaning agent composition treatment is placed on its back on a towel (pseudo pillow), and then moved 10 cm while dragging toward the neck of the wig to evaluate the difficulty of falling asleep. , It was left to stand for 1 hour.
Then, after raising the wig, the hair part with the nap was lightly stroked three times while passing the hand comb at a speed of 20 cm / sec.
The state after stroking was selected by seven panelists as to whether it was "difficult to fall asleep" / "neither can be said" / "easy to fall asleep". The number of panelists who answered "It's hard to get to sleep" / "I can't say either" / "It's easy to get to sleep" is shown in order.
