Description

  The present invention relates to a hair cosmetic, and preferably a hair cosmetic such as a hair rinse and a hair conditioner that is applied to shampooed hair and washed with water after a predetermined time.

  Hair is always affected by sunlight, ultraviolet rays, heat, drying, and the like, and tends to be pricked by daily hair washing, brushing, the heat of a dryer, and the like. Furthermore, in recent years, it has become common to enjoy changes in the appearance of hair, such as changing the hair color freely (coloring), changing the hairstyle (perm, etc.), and the frequency of these changes has increased. ing. However, the repetition of coloring and permanent causes mechanical physical hair damage, for example, cavities are formed inside the hair and as a result, the elasticity of the hair is lost. Further, since the friction on the hair surface increases, the hairs are easily entangled during washing and drying. In particular, the damaged hair ends have undulations different from the original shape of the hair in addition to mechanical property damage and increased surface friction, and the hair is oriented in a disjointed direction, i.e. It becomes splash hair.

  Accordingly, various attempts have been made for the purpose of repairing hair damage. For example, for the purpose of repairing cavities in the hair and restoring the mechanical and optical properties of hair, hair cosmetics containing an organic acid, amino acid, and cationic surfactant (Patent Document 1), organic acids, polypropylene glycol, Hair cosmetics containing a cationic surfactant or the like have been proposed (Patent Documents 2 and 3). In addition, for the purpose of imparting flexibility to hair and suppressing tangles, a hair cosmetic using an aromatic sulfonic acid such as an amidoamine compound, a higher alcohol, or naphthalenesulfonic acid has also been proposed (Patent Document 4).

  However, even though these hair cosmetics can restore the mechanical and optical properties of hair damaged by hair color, etc., and reduce the surface friction of the hair to impart flexibility and slipperiness to the hair. The function of restoring hair undulation caused by the accumulation of damage was insufficient.

Dry while gently shaking. After drying, the curl radius was measured (post-treatment radius). The change (curl diameter ratio) before and after treatment was determined based on the following formula, and the average of 5 test pieces is shown in Table 1. The greater the curl diameter ratio, the greater the effect of undulation.

      Curl diameter ratio = (curl radius after treatment) ÷ (curl radius before treatment)

Examples 1-6 and Comparative Examples 1-3
Hair cosmetics (hair conditioners) shown in Table 2 were produced, and each was subjected to a sensory evaluation test according to the following procedure. The pH is a value at 25 ° C. when diluted 20 times by mass with water.

(Smoothness during application and rinsing)
A hair bundle with a length of 20cm, a width of 5.5cm, and a weight of 10.0g was prepared in advance using bleached hair that had been bleached 8 times and washed and dried 720 times in advance. A 1.0g plain shampoo (polyoxyethylene ( 2.5) Prepare with sodium lauryl ether sulfate and diethanolamide), and then lightly drain and apply 1.0g of hair conditioner. At that time, the smoothness during application is evaluated. Then, it rinses for 30 seconds with 40 degreeC flowing water of 6 L / min, and the smoothness at the time of a rinse is evaluated. The evaluation was performed by five people, and the total value of the evaluation was shown.

・ Evaluation criteria 4: Slip well 3: Slightly slip 2: Not slippery 1: Not slippery

(Effects to restore bounce and wavy hair tips to their original straight state)
After washing the hair bundle of length 20cm, width 5.5cm, and weight 10.0g well with 1.0g plain shampoo, pre-bleached 8 times and hair damaged and dried 720 times in advance. Lightly drain the water and apply 1.0g of hair conditioner. Then, rinse with 40 L running water at 6 L / min for 30 seconds, towel dry, and dry thoroughly with warm air from a dryer for 2-3 minutes. This was done once and repeated 20 times in total. Using the hair bundle after repeating 20 times, the degree to which the undulation of the hair tip can be removed was visually evaluated. The evaluation was performed by five people, and the total value of the evaluation was shown.

・ Evaluation criteria 4: Swelling is removed 3: Slightly swelling is taken 2: Not much swelling is taken 1: Swelling is not taken
