Description

  The present invention relates to a hair cosmetic.

  Hair is always affected by ultraviolet rays, heat, and drying caused by sunlight, and is apt to be pricked by daily hair washing, brushing, the heat of a dryer, and the like. In particular, the damaged hair ends have undulations that are different from the original shape of the hair in addition to mechanical property damage and increased surface friction. It is said that it results in splashing hair, and as a result, the hair becomes dry, the finger passage is poor, the hair does not settle, the gloss and smoothness are lost.

  As hair cosmetics that have been tried to improve the hair by modifying the inside of the hair, those using specific organic acids and organic solvents are known (see, for example, Patent Documents 1 to 3). However, although these techniques are excellent in the effect of improving hair gloss and cohesiveness, they are not sufficiently satisfactory in touch. Therefore, general silicones are blended as a touch improver. However, although the touch is improved by the use of silicones, there is a possibility that the effect of modifying hair (such as gloss and cohesiveness) by organic acids and organic solvents may be reduced.

  Furthermore, an attempt has been made to use an aromatic sulfonic acid such as naphthalene sulfonic acid in combination for the purpose of imparting flexibility to hair and suppressing wrinkling (Patent Document 4). However, it is possible to reduce the surface friction of hair damaged by hair color, etc., and to impart flexibility and slipperiness to the hair. It was insufficient to improve the property and setability.

The hair cosmetics shown in Table 2 were prepared and evaluated according to the criteria shown in Table 1 for “swelling improvement effect”, “smoothness”, “smoothness”, and “shininess”. These results are shown in Table 2.

(1) Evaluation hair bundle Using a Japanese woman's hair that has not undergone chemical treatment such as perm, hair color, etc., make a hair bundle of 25cm length and 6g weight, and then bleaching treatment (using Kao Corporation, Prettyia Hybrid) ) 4 times, and repeatedly washing and drying 720 times to obtain an evaluation hair bundle.

(2) Treatment of hair bundles ・ Evaluation before shampooing After shampooing the evaluation hair bundle (Kao Co., Pure shampoo), towel drying, uniformly apply 0.6 g of the hair cosmetics shown in Table 2 and warm air at 70 ° C Using a ring comb, it was dried for 10 minutes while combing. This process was repeated a total of 7 times.

・ Evaluation after hair washing In order to investigate the effect of modifying the inside of the hair, shampoo and towel dry each hair bundle for which the above pre-washing evaluation has been completed, and use a ring comb with hot air at 70 ° C. Dried for minutes.

(3) Evaluation criteria Sensory evaluation was performed according to the criteria shown in Table 1 by five professional panelists, and the average value of the evaluation points was obtained.
