[Examples]

(Examples 1 to 9 and Comparative Examples 1 to 9)

Hair cosmetics having the compositions shown in Tables 1 and 2 were prepared according to the following methods and evaluated. The evaluation method and evaluation criteria are shown below.

(Method of manufacturing hair cosmetic)

The component (B) or (B'), (C) and (D) are mixed and dissolved in water heated to 60 ° C, and then the component (A) is added to be uniform, and cooled to room temperature to obtain hair. Cosmetic composition.

(pH measurement method)

The pH value was diluted with purified water to 20 times by mass, and stirred and dissolved, and then measured at 25 ° C using a pH meter (Model HM-30R) manufactured by DAK Corporation of East Asia.

(production of hair bundles for evaluation)

A hair bundle of 25 cm in length was prepared using 5 g of untreated Japanese hair, and bleaching hair was prepared.

The bleaching treatment is carried out by using the Prettia foam bleaching highly bleached by Kao Co., Ltd., and the mixing ratio of 1 liquid to 2 liquid is 1:2, the bath ratio of hair to mixed liquid is 1:3, room temperature and immersion time 20 minutes. . After the immersion treatment, the mixture was washed with tap water of 40 ° C and dried with a towel, and then dried by a hair dryer. The series of processors will be used as "evaluation bundles" three times.

(Method of processing hair bundles for evaluation)

After the evaluation hair bundle was soaked with tap water of 40 ° C, 0.5 g of the evaluation shampoo shown below was applied, and after foaming for 30 seconds, it was rinsed with tap water of 40 ° C. its Thereafter, it was dried with a towel and dried by a hair dryer for 3 minutes while applying a hand combing operation. This is referred to as "hair bundle for evaluation before processing".

Further, after the evaluation hair bundle was wetted with tap water of 40 ° C, 0.5 g of the shampoo for evaluation shown below was applied, and after 30 seconds of foaming, it was rinsed with tap water of 40 ° C. To the hair bundle, 0.5 g of the hair cosmetic of each of the examples described in the table was applied and allowed to stand for 5 minutes.

Thereafter, the hair bundle was sufficiently rinsed with tap water of 40 ° C, dried with a towel, and dried by a hair dryer for 3 minutes while combing by hand. This is referred to as "hair bundle for evaluation after processing".

Evaluation shampoo formula (pH 7.0)

(Evaluation of hair cuticle peeling inhibition during stretching)

1. Evaluation from the above treatment Five hairs were randomly taken out with hair bundles, and shaved from the hair tips 10 cm to 15 cm (hair length 5 cm). Invisible tape (manufactured by Scotch Co., Ltd.) was attached to the 0.5 cm portion of both ends of the shaved hair so as to be fixed from the upper and lower sides.

Then, with respect to the shaved hair, the fixing portion was grasped at a stretching speed of 0.1 cm/sec, and the elongation was 25% (the hair of the unattached portion of the tape was elongated from 4 cm before being stretched to 5 cm). The way is extended along the axis of the hair. Will not extend the hair after extension The method of moving was fixed on a glass slide using a two-part adhesive as a sample for measurement.

2. Using the above-mentioned sample for measurement, the surface shape of the hair was measured by a laser microscope (manufactured by KEYENCE, VK-8700) (measurement pitch: 0.1 μm), and the slope derived from the hair produced on the sample on the soft body was produced. (Because of the slide or invisible tape, etc.) The surface slope correction is performed (3 points are specified). Thereafter, the average height Rc value (JIS B0601: 2001) of the roughness curve element as the JIS standard was calculated. As a calculation method, a straight line having a length of 200 μm was drawn in the axial direction on the surface of the hair subjected to the slope correction, and the Rc value (μm) on the straight line was calculated on the soft body. This operation was performed 5 times on the surface of the randomly selected hair, and the average value thereof was determined.

It is suggested that the larger the Rc value, the thicker the surface shape becomes, that is, the peeling of the stratum corneum is promoted, and the smaller the value, the more the peeling of the stratum corneum is suppressed.

(Functional evaluation: the gloss after the hair is dried)

For the evaluation of the hair bundles after the above-mentioned treatment, the "gloss", "uniformity" and "wetness" of the dried hair bundles were evaluated by the professional panel inspectors according to the following criteria, and the average score was calculated for each item. .

(luster)

5: Compared with the "hair bundle before evaluation", it is shiny.

4: slightly shiny compared with the "hair bundle before evaluation"

3: The gloss is roughly the same as the "hair bundle for evaluation before treatment"

2: slightly dull compared to the "pre-treatment evaluation hair bundle"

1: matte compared to "hair bundle before evaluation"

(tidiness)

5: Compared with the "pre-treatment evaluation hair bundle", there is uniformity

4: A little more uniform than the "hair bundle before evaluation"

3: The uniformity is roughly the same as the "hair bundle for evaluation before processing"

2: Compared with the "pre-treatment evaluation hair bundle", there is no uniformity.

1: No uniformity compared with "Before evaluation evaluation"

(wet feeling)

5: There is a feeling of humidity compared with the "hair bundle for evaluation before treatment"

4: A little moist feeling compared with the "pre-treatment evaluation hair bundle"

3: The moist feeling is almost the same as the "hair bundle for evaluation before treatment"

2: Compared with the "pre-treatment evaluation hair bundle", there is no feeling of moistness.

1: No moist feeling compared with "Before evaluation evaluation"

According to Tables 1 and 2, the hair bundle obtained by applying the hair cosmetics obtained in Examples 1 to 9 was used to reduce the effect of increasing the Rc value at the time of extending the warp, that is, suppressing the stratum corneum, compared with the respective comparative examples. The effect of the peeling effect and the balance of the effects of the gloss, the uniformity and the moist feeling of the hair after the care are more excellent.

(Embodiment 10)

After the above-mentioned evaluation hair bundle was soaked with tap water of 40 ° C, 0.5 g of the shampoo for evaluation shown above was applied, and after foaming for 30 seconds, it was rinsed with tap water of 40 ° C. After applying 0.5 g of the hair cosmetic described in Example 2 to the tuft, 0.5 g of the hair lotion of the formulation shown below was applied and allowed to stand for 5 minutes.

Thereafter, the hair bundle was sufficiently rinsed with tap water of 40 ° C, dried with a towel, and dried by a hair dryer for 3 minutes while combing by hand.

Hair repairing cream formula

The hair bundle obtained by the above treatment has an effect of reducing the increase in the Rc value at the time of extending the warp, that is, the effect of suppressing the peeling of the stratum corneum, and after the care, as compared with the case of treating only the hair cosmetic of Example 2. The balance of the effects of the luster, the uniformity and the moist feeling of the hair is more excellent.
