Description

The present invention relates to a hair cleanser, a hair cosmetic set, a shampoo/treatment method, and an acid/heat treatment method.

In the development of hair cleansers, research has so far been mainly aimed at improving the detergency of hair to remove dirt and the refreshing feeling after washing.
However, when the cleansing power and the refreshing feeling after washing were improved, the hairs generally became tangled and squeaked, making it difficult to pass through the hair with fingers. Furthermore, there was a problem in that the hair after finishing was dry, easily spread, and felt stiff.

In recent years, new technological developments have been underway to solve these problems. For example, Patent Document 1 describes the use of specific taurine salts (a), anionic surfactants (b), and amphoteric surfactants. A shampoo composition is disclosed that includes specific amounts of an active agent (c), a cationized polymer (d), and a water (e) component.

The hair cleansers produced in Examples 1 to 42 gave good results in evaluation items (1) to (9). The hair cosmetics produced in Examples 43 to 44 gave good results in the evaluation items (1) to (11).

In the evaluation item (11), the hair cosmetic produced in Example 45 used a conventional hair cleansing agent for pre-shampoo, but used the hair cleanser produced in Example 43 for after-shampoo after acid/heat treatment. Good results were obtained due to the use of this agent.

From the evaluation results of (11) in Example 45 and the evaluation results of (11) in Comparative Example 14, it is clear that when the hair cleansing agent of the present invention is used on hair that has been subjected to acid/heat treatment, It can be seen that compared to hair cleansers, the hair straightens out better.

The hair cosmetics produced in Examples 42 and 43 had particularly good results in all of the evaluation criteria (1) to (11).

It can be seen that the hair cleansing agent of the present invention is a hair cleansing agent that can clean the scalp refreshingly, has excellent finger combing properties, and is also excellent in consistent softness from the time of washing to the finish.

Since the hair cleansing agent produced in Comparative Example 1 contained less than the specified amount of acyl isethionate (A), it did not foam well during washing, had a sticky feeling during rinsing, and did not leave the scalp feeling refreshed. Also, my hair felt stiff when I washed it.
The hair cleansing agent produced in Comparative Example 2 contained more acyl isethionate (A) than the specified amount, so it was difficult to run the fingers through the finished hair.

Since the hair cleansing agent produced in Comparative Example 3 contained less acylamino acid salt (B) than the specified amount, it was difficult to run fingers through the hair during rinsing, and the finished hair felt hard.
Since the hair cleansing agent produced in Comparative Example 4 contained more acylamino acid salt (B) than the specified amount, it felt sticky during rinsing and did not leave the scalp feeling refreshed.

Since the hair cleansing agent produced in Comparative Example 5 contained less of the anionic surfactant (C) than the specified amount, it did not foam well during washing and did not leave the scalp feeling refreshed.
Since the hair cleansing agent produced in Comparative Example 6 contained more of the anionic surfactant (C) than the specified amount, the hair felt hard during washing, rinsing, and after finishing. In addition, the hair was disorganized and spread out.

The hair cleansing agent produced in Comparative Example 7 contained less betaine type amphoteric surfactant (D) than the specified amount, so it did not foam well during washing and the finished hair felt hard.
Since the hair cleansing agent produced in Comparative Example 8 contained more betaine type amphoteric surfactant (D) than the specified amount, it felt sticky during rinsing and did not leave the scalp feeling refreshed.

Since the hair cleansing agent produced in Comparative Example 9 contained less cationic polymer (E) than the specified amount, the hair felt hard during washing and rinsing. Also, it was difficult to run my fingers through the hair during rinsing.
Since the hair cleansing agent produced in Comparative Example 10 contained more cationic polymer (E) than the specified amount, it did not foam well during washing and did not leave the scalp feeling refreshed. Also, the finished hair felt stiff.

Since the hair cleanser produced in Comparative Example 11 contained less cocoyl arginine ethyl PCA (F) than the specified amount, the hair felt hard during washing, rinsing, and after finishing. In addition, the hair was disorganized and spread out.
Since the hair cleansing agent produced in Comparative Example 12 contained more cocoyl arginine ethyl PCA (F) than the specified amount, it did not foam well during washing and did not leave the scalp feeling refreshed.

The hair cleanser manufactured in Comparative Example 13 has a conventional hair cleanser formulation. Lathering was poor during washing, and the hair felt stiff during washing, rinsing, and after finishing. In addition, the hair was disorganized and spread out. There was a feeling of adhesion when rinsing, and it was difficult to run my fingers through the hair.

In Comparative Example 14, pre-shampoo and after-shampoo after acid/heat treatment were performed using a conventional hair cleansing formulation (same as Comparative Example 13), resulting in poor lathering during washing and during washing and rinsing. My hair felt stiff. In addition, because a series of shampoo treatments were repeated using a conventional hair cleansing agent as an after-shampoo, a total of 7 times, there was only a slight increase in the curl of the hair.
