Description

The present invention relates to a multi-component hair cosmetic and a hair treatment method.

Hair is damaged by the UV rays it receives in daily life and the effects of shampoos and hair dryers. Additionally, hair may become thinner due to the effects of aging and other factors. When damaged or thinned hair is subjected to chemical treatments such as hair coloring agents, perm agents, etc., or heat treatments such as curling irons or hair dryers, the hair becomes stiff, dry, and difficult to pass through with fingers. There is a desire for a hair cosmetic that can improve the condition of hair that has been significantly damaged, making it easier to style, have a good texture, and is easy to run through the fingers, and that can maintain this effect for a certain period of time.

Research and development has been conducted to improve the condition of hair where significant damage has appeared. One of the methods developed is a multi-component hair cosmetic in which multiple preparations are applied to the hair in sequence to enhance the hair repair effect and texture improvement effect (Patent Documents 1 to 3). For example, a multi-component hair cosmetic in recent years has been disclosed as a multi-component hair treatment agent in which the first, second, and third components are applied to the hair in that order, and which is composed of the first component containing a cationic compound, the second component containing an anionic polymer selected from a specific copolymer or its crosslinked product, and the third component containing a cationic compound (Patent Document 4).

Japanese Patent Application Publication No. 2008-137995 Japanese Patent Application Publication No. 2010-215541 JP 2012-056931 A JP 2013-144646 A

However, in the technique of Patent Document 4, since the adsorption power of the first agent to the hair is high, although the hair is soft and smooth, there is a problem that the hair becomes sticky. Furthermore, by applying the second and third agents to the hair, stickiness was eliminated, but the hair became hard, lost its softness, and was difficult to run through with fingers, resulting in unsatisfactory quality. Another problem was that the effect of softening and calming hair cannot be felt after washing with shampoo.

In view of the above, the present invention aims to provide a multi-ingredient hair cosmetic product that is non-sticky, soft, easy to run fingers through the hair ends, and easy to manage, and that maintains excellent effects of softness, ease of running fingers through the hair ends, and manageability for a certain period of time even after washing with shampoo.

Damage Processing
The hair bundles used in Examples 1 to 35 and Comparative Examples 1 to 10 were previously subjected to a damage treatment by the following method in order to reproduce the damage and frizziness experienced by an average person's hair.
A mixture of 10 g of bleaching agent Arimino 120 Bleach (Arimino Co., Ltd.) and 20 g of Color Story Admio OX6% (Arimino Co., Ltd.) was applied to a bundle of hair (30 cm, 10 g of black human hair) (product name BS-B3A, manufactured by Beaulux Co., Ltd.) with a brush and left at 25°C for 30 minutes to damage the hair. The hair was then rinsed with running water and shampooed with 1 g of Sherpa Design Supplement D-2 Shampoo (Arimino Co., Ltd.). After shampooing, the hair was rinsed with running water and dried with a hair dryer.

Evaluation Procedure A: Examples 1 to 27 and Comparative Examples 1 to 10
The damaged hair bundle was wetted with hot water at about 35 to 40°C, and then 1 g of the first agent prepared according to each of the formulations shown in Tables 2 to 5 was applied and blended into the entire hair bundle. 1 g of the second agent prepared according to each of the formulations shown in Tables 2 to 5 was applied to the hair bundle to which the first agent had been applied, and blended into the entire hair bundle. The hair bundle was then rinsed with hot water, towel-dried, and then dried with a hair dryer for finishing. The finished hair bundle was subjected to a sensory evaluation according to the evaluation items (1) to (5). Note that only in Example 3, the finished hair bundle was also subjected to a sensory evaluation according to the evaluation item (6).

《Evaluation procedure B: Examples 28 to 35》
After wetting the damaged hair bundle with hot water, 1 g of the first agent prepared according to the formulation described in Example 3 was applied and blended into the entire hair bundle. To the hair strands to which the first agent had been applied, 1 g of the second agent prepared according to the formulation described in Example 3 was applied in an overlapping manner, blended over the entire hair strand, and rinsed with hot water. After rinsing, 1 g of the third agent prepared according to each formulation listed in Tables 7 and 8 was applied to the lightly drained hair strands and blended into the entire hair strand. After that, I rinsed it with hot water, towel dried it, and then dried it with a hair dryer to finish it off. The finished hair bundles were subjected to sensory evaluation according to the evaluation items (1) to (6).

4 points: no stickiness felt 3 points: almost no stickiness felt 2 points: slightly sticky 1 point: very sticky (2) Evaluation item 2: Softness The softness was evaluated by touch by running fingers through the finished hair bundle or by squeezing it.
4 points: Very soft 3 points: Soft 2 points: Slightly hard 1 point: Very hard

(3) Evaluation item 3: Smoothness of running fingers through hair to the ends Fingers were run through the finished hair bundle, and the smoothness of running fingers through the hair bundle from the middle to the ends was evaluated.
4 points: Very smooth 3 points: Smooth 2 points: Slightly rough and sticky 1 point: Very rough and sticky (4) Evaluation item 4: Smoothness The finished hair bundle was combed with a comb and the ends of the hair were straightened with hands, and the smoothness of the ends was visually evaluated.
4 points: Very organized 3 points: Well organized 2 points: Spread out 1 point: Very spread out

(5) Evaluation item 5: Smoothness of running fingers through hair to the ends after washing The finished hair bundle was immersed in a 10% aqueous solution of sodium laureth sulfate for 5 minutes, and then washed with hot water. The hair bundle was towel-dried and then dried with a hair dryer. The evaluation was carried out in the same manner as in evaluation item 3, and the smoothness of running fingers through the ends was evaluated.
The immersion time of 5 minutes in a 10% aqueous solution of sodium laureth sulfate is equivalent to approximately 2 weeks' worth of shampooing in daily life.
4 points: very smooth 3 points: smooth 2 points: slightly sticky and rough 1 point: very sticky and rough (6) Evaluation item 6: Moisture sensation The finished hair bundle was run through its fingers and squeezed to evaluate the moisture sensation by touch.
4 points: Very moisturizing 3 points: Moisturizing 2 points: Dry 1 point: Very dry
