Description

Hair cosmetic

The present invention relates to a rinse-off hair cosmetic material applied to hair after rinsing.

Hair rinses such as hair rinse and hair conditioner used after shampooing are based on cationic surfactants or higher alcohols. The purpose is to impart smoothness to hair. Sexual or hydrating feeling makes the surface condition of the hair neat. For example, Patent Documents 1 to 3 disclose hair conditioners having excellent uniformity and volume after use, such as cationic surfactants, higher alcohols, and aromatic sulfonic acids.

In addition, Patent Document 4 discloses a rinse-free hair conditioner combining M3T (methyl polytrimethylsiloxane) as a volatile polysiloxane, a nonvolatile polysiloxane derivative, and a cationic surfactant. combination. Patent Document 4 describes that the hair conditioning composition dries quickly after being applied to dry hair, and has an excellent effect of imparting dry touch and softness to hair.

The present invention provides a hair cosmetic material, which is used in a way of rinsing a user after applying the hair, and contains ingredients (A) to (D) and water, and the mass ratio of the ingredients (A) to (D) (A ) / (D) exceeds 1.5.

In recent years, not only chemical treatments such as hair dyeing and perming, but also the use of hot hair irons, such as hair irons and hair dryers, which have become habitually used by young women as the center, have caused serious damage to hair. It is known that hair damage is caused by the loss of 18-MEA (18-methyl eicosanoic acid), which is a fatty acid covering the surface of the hair, causing the surface of the hair to become hydrophilic and the surface friction to increase. Damaged and hydrophilized hair not only loses its smoothness, but also does not easily dry out after shampooing. It takes a long time to blow dry with a hair dryer or the like, which causes a burden on physical strength. In addition, the damaged hair during wet hair is easily tangled, and the knots generated during the drying process with a hair dryer will cause damage to accumulate and cause a consumer's psychological burden.

The aforementioned Patent Document 4 describes that the hair conditioning composition dries quickly after being applied to the hair. However, the hair conditioning composition specifically disclosed in this document is only a rinse-free type, and the effect of "faster drying after application" in the invention also refers to the faster drying of the hair conditioning composition itself. Therefore, there is no suggestion in this document as to how fast the hair after drying it is applied to a type of hair cosmetic material that is rinsed after application.

Therefore, the present invention relates to a hair cosmetic material, which can be applied to hair after washing with shampoo and rinsed, so that wet hair can be tangled and dried in a short period of time, and the fluffy volume can be given to the dried hair. Feeling, dry feeling.

As a factor for improving the drying speed of hair after shampooing, it is important to "loose the hair". That is, because the hair is loose, the area of contact with the towel is increased when it is dried with a towel, so that the moisture of the hair is quickly absorbed by the towel, or when it is dried with a hair dryer (dried naturally) Also when dry) the contact area with the air increases and the moisture of the hair evaporates quickly.

The inventors have found that by using a combination of aromatic sulfonic acid and cationic surfactant in a certain ratio of rinse-type hair cosmetics used after shampoo due to conditioners, conditioners, and the like, a mistake can be made between the two. The complex can be used as a spacer between hairs, and methyl polytrimethylsiloxane, which is a volatile polysiloxane, can alleviate the tangles of hair and weaken the adhesion of attached components on the hair. In addition, if these complexes serving as spacers coexist with methyl polytrimethylsiloxane, the wet hair after treatment is easily loosened, no tangles are caused, and the drying speed can be dramatically improved.

[Example]

Examples 1 to 13 and Comparative Examples 1 to 8

The hair creams shown in Tables 1 and 2 were prepared and evaluated according to the following methods and criteria.

(Easy to loose hair)

Hair bundles obtained by implanting 30 cm of hair with a density of 200 hairs / cm ² within a range of 6 cm × 6 cm at a density of 200 hairs / cm ² at an implantation angle of 60 ° were made using commercially available bleach (manufactured by Kao Corporation, Bubble Hair Color High). Bleach) was subjected to two bleaching treatments (5 mass times of bleach applied to the hair, and treatment was performed at room temperature for 30 minutes) to evaluate the looseness of the hair bundle. After the produced hair bundle was washed twice with plain shampoo, 1 g of the shampoo described in Tables 1 and 2 was applied and rinsed with tap water. After rinsing, a paper towel (Elleair Prowipe, manufactured by Dawang Paper Co., Ltd.), an acrylic plate, and a hammer (total weight of the acrylic plate and the hammer 1.3 kg) were sequentially placed on the hair bundle with the moisture content adjusted to 10 g, and excess water was removed. The ease of loosening of hair bundles and the formation of smaller bundles of hair when combing the bundles with fingers were regarded as "easy loosening of hair bundles", and functional evaluation was performed by five researchers. The evaluation is performed at five levels below, and the total score of five researchers is calculated.

5: Easy to loose

4: Easy to loose

3: Slightly loose (difficult to evaluate)

2: Slightly difficult to loosen

1: Not easy to loose

(Not easily tangled during drying)

Using the above hair tress, the sample was treated in the same manner, and excess water was removed using a paper towel. Next, set the hair bundles downward, and fix the hair dryer and the hair bundles in such a way that the distance from the hair dryer (National Corporation, TURBODRY1300) to the center of the hair is 25cm, and the warm air blows from about 45 ° obliquely upward. , While combing with your fingers once every 4 seconds, dry the hair dryer. At this time, five researchers conducted a sensory evaluation of "not easily tangled" until completely dry. The evaluation is performed at five levels below, and the total score of five researchers is calculated.

5: Not tangled

4: Hardly tangled

3: difficult to evaluate

2: Slightly tangled

1: easily tangled

(Fluffy)

Using the above hair tress, after performing the sample treatment in the same manner, with the hair tips facing down, the hair tress was completely dried with a hair dryer. After being completely dry, five researchers performed a sensory evaluation on the appearance when the hair bundles were placed on the table in an inverted state and the "fluffy feeling" when combed with fingers. The evaluation is performed at five levels below, and the total score of five researchers is calculated.

5: Very fluffy

4: Has a fluffy feel

3: Slightly fluffy

2: Not too fluffy

1: No fluffy feeling

(Dry feeling)

Using the above hair tress, after performing the sample treatment in the same manner, with the hair tips facing down, the hair tress was completely dried with a hair dryer. After being completely dry, the smoothness, softness when combing with fingers, and the feeling that the hair bundles did not adhere to each other and easily became loose were regarded as "dryness", and the functional evaluation was performed by 5 researchers. The evaluation is performed at five levels below, and the total score of five researchers is calculated.

5: Very dry

4: Dry feeling

3: Slightly dry

2: Not too dry

1: No dry feeling

(Time until feeling dry)

Using the hair tress described above, excess water was removed with a paper towel after sample treatment in the same manner. Next, set the hair bundles downward, and fix the hair dryer (warm wind mode, air flow: weakest) to the hair bundles so that the distance from the hair dryer (National Corporation, TURBODRY1300) to the hair center is 25cm. While combing with fingers every 4 seconds, the dryer was dried. At this time, the time from the start of the drying of the hair dryer to the time when the researcher can judge that the hair is completely dry is measured, and the quick-drying property is evaluated.
