Description

  The present invention relates to a hair cosmetic that is washed off after being applied to hair.

  The type of hair cosmetics to be washed away, such as hair rinses and hair conditioners, used after shampooing the hair, is based on cationic surfactants and higher alcohols, and provides a smooth and moist feel to the hair to condition the surface of the hair. It is aimed. For example, Patent Documents 1 to 3 disclose hair conditioners and the like that are excellent in unity after use, volume feeling, and the like, in which a cationic surfactant, a higher alcohol, an aromatic sulfonic acid, and the like are blended.

  Patent Document 4 discloses a hair conditioning composition of a type that does not wash away, which is a combination of M3T (methyltrimethicone), which is a volatile silicone, a non-volatile silicone derivative, and a cationic surfactant. Patent Document 4 describes that this hair conditioning composition is fast in drying after being applied to dry hair, and has an excellent effect of imparting a smooth feel and flexibility to the hair.

  In recent years, in addition to chemical treatments such as hair coloring and perm, hair damage caused by hair sets using heat such as hair irons and hair dryers, which has become a habit mainly for young women, has become serious. It is known that hair damage is accompanied by the loss of 18-MEA (18-methyleicosanoic acid), which is a fatty acid covering the hair surface, and causes increased surface friction as the hair surface becomes hydrophilic. Damaged and hydrophilized hair not only loses its smoothness but also becomes difficult to dry after shampooing, and it takes a long time to dry with a dryer or the like, which is a physical burden. In addition, wet damaged hair tends to get entangled, and the catches that occur during drying of the dryer add to the accumulation of further damage and the psychological burden on the consumer.

  Patent Document 4 described above describes that drying after applying a hair conditioning composition to hair is fast. However, the hair conditioning composition specifically disclosed in the document is only a type that does not wash away, and the effect of “fast drying after application” in the present invention is that the hair conditioning composition itself dries quickly. is there. Therefore, this document does not suggest at all the speed of drying after using a type of hair cosmetic that itself is washed away after application to the hair.

  Therefore, the present invention can dry wet hair in a short time without tangling by applying it to the hair after shampooing and washing it, and can give a soft volume and smooth feeling to the hair after drying. It is related with the hair cosmetics which can be performed.

  As a factor for increasing the drying speed of the hair after washing, “separation of hair” is important. That is, when the hair is dispersed, the contact area with the towel increases when the towel is dried, and moisture of the hair is absorbed quickly by the towel, and when the dryer is dried (even during natural drying), the contact area with the air is increased. Will increase and the moisture of the hair will evaporate quickly.

  The inventors of the present invention use a combination of an aromatic sulfonic acid and a cationic surfactant in a constant proportion in a hair cosmetic that is used after shampooing, such as a hair rinse, a hair conditioner, etc., thereby forming a complex of both. It can be a spacer between hairs, and methyltrimethicone, which is a volatile silicone, can weaken the stickiness of adhering components on the hair while tangling hair, and further, these spacer complexes and methyltrimethicone It has been found that the coexistence of and makes it easy to disperse wet hair after treatment, and can dramatically improve the drying speed without entanglement.

The present invention is a hair cosmetic that is used after being applied to the hair and is washed away and contains the components (A) to (D) and water, and the mass ratio (A) between the components (A) and (D). / (D) provides hair cosmetics with more than 1.5.

Examples 1-10 and Comparative Examples 1-8
Hair conditioners shown in Tables 1 and 2 were prepared and evaluated according to the following methods and criteria.

(Ease of loosening of hair bundles)
Bleach treatment with a commercial bleaching agent (Kao Co., Ltd., Foam Color Hybrid), which is a 6cm x 6cm square with a density of 200 strands / cm ² and a hair angle of 60 ° and a hair length of 30cm. (Applying a bleaching agent 5 times as much as hair and treating at room temperature for 30 minutes) was performed twice, and used for evaluating the ease of loosening of the hair bundle. The prepared hair tress was washed twice with a plain shampoo, and then 1 g of the conditioner described in Tables 1 and 2 was applied and rinsed with tap water. After rinsing, put a paper towel (Daiou Paper Co., Eliere Pro Wipe), acrylic board, weight (total weight of acrylic board and weight 1.3kg) on the hair trace adjusted so that the water content is 10g. Excess water was removed. The ease of loosening of the hair bundle when the finger was passed through the tress and the ease of producing a small hair bundle was defined as “Ease of dispersal of the hair bundle”, and sensory evaluation was conducted by five researchers. Evaluation was performed in the following five stages, and the total score of five people was calculated.
5: Very easy to break 4: Easy to break 3: Slightly loose (cannot say either)
2: Slightly difficult to break 1: Slightly difficult to break

(Difficult to get tangled during drying)
Using the above-mentioned tres, the sample was processed in the same manner, and excess water was removed with a paper towel. Next, place the hair tress downward and fix the dryer and the hair tress so that the distance from the blower outlet of the dryer (National TURBODRY1300) to the center of the hair is 25 cm and the warm air hits from about 45 ° diagonally. Then, the dryer was dried while passing a finger once every 4 seconds. At this time, sensory evaluation was performed by five researchers on “hardness of entanglement” until it was completely dried. Evaluation was performed in the following five stages, and the total score of five people was calculated.
5: Not entangled 4: Almost entangled 3: Neither can be said 2: Slightly entangled 1: Slightly entangled

(Soft feeling)
After the sample was processed in the same manner using the above-mentioned tress, it was completely dried with a drier so that the hair ends faced downward. After drying completely, sensory evaluation was performed by five researchers on the appearance when the hair tress was turned upside down and placed on the table, and the “soft feeling” when it was passed through the fingers. Evaluation was performed in the following five stages, and the total score of five people was calculated.
5: Very soft feeling 4: Soft feeling 3: Soft feeling 2: Soft feeling 1: Not soft feeling

(Smooth feeling)
After the sample was processed in the same manner using the above-mentioned tress, it was completely dried with a drier so that the hair ends faced downward. After being completely dried, the smoothness, lightness, and the feeling that the hair bundles did not adhere to each other and were easily broken apart were defined as “smoothness” and sensory evaluation was conducted by five researchers. Evaluation was performed in the following five stages, and the total score of five people was calculated.
5: There is a very smooth feeling 4: There is a smooth feeling 3: There is a little smooth feeling 2: There is not much smooth feeling 1: There is no smooth feeling

(Time to feel dry)
Using the above-mentioned tres, the sample was processed in the same manner, and excess water was removed with a paper towel. Next, place the hair tress downward, and fix the hair tress (dry air mode, air flow: weakest) and the hair tress so that the distance from the hair outlet of the dryer (TURBODRY1300 manufactured by National Corporation) to the center of the hair is 25 cm. Then, the dryer was dried while passing a finger once every 4 seconds. At this time, the time from the start of drying of the dryer until the researcher was able to judge that the hair was completely dried was measured, and the quick drying property was evaluated.
