Description

Hair cosmetic

The present invention relates to a rinse-type hair cosmetic which is applied after rinsing.

Sexual or hydrating to make the surface of the hair become neat. For example, in the patent documents 1 to 3, a hair conditioner or the like which is excellent in uniformity and volume feeling after use, such as a cationic surfactant, a higher alcohol, and an aromatic sulfonic acid, is used.

The present invention provides a hair cosmetic which is applied to a user after being applied to the hair, and contains the components (A) to (D) and water, and the mass ratio of the component (A) to the component (D) (A) ) / (D) exceeds 1.5.

(A) cationic surfactant: 0.1% by mass or more and 10% by mass or less

(B) higher alcohol: 1% by mass or more and 10% by mass or less

(C) methyl polytrimethyl decane: 0.05% by mass or more and 15% by mass or less

In recent years, not only chemical treatments such as hair dyeing and perming, but also hair styling, hair dryers, etc., which are gradually used by young women, have been seriously damaged by hair. Hair damage is known to cause the surface of the hair to become hydrophilized and the surface friction to increase with the loss of fatty acid 18-MEA (18-methyl eicosanoic acid) which is coated on the surface of the hair. The damaged and hydrophilized hair not only loses smoothness, but also does not dry easily after shampooing, and it takes a long time to blow dry with a hair dryer or the like, which imposes a burden on the physical strength. Moreover, the damaged hair during wet hair is easy to entangle, and the knotting generated during the drying process by the hair dryer causes the damage to accumulate and burdens the consumer's mind.

In the above Patent Document 4, it is described that the hair conditioning composition is applied to the hair and dried quickly. However, the hair conditioning composition specifically disclosed in this document is only a rinse-free type, and the effect of "slow drying after application" in the invention also means that the hair conditioning composition itself dries faster. Therefore, the speed of drying in the literature after using the hair cosmetic of the type which is applied to the hair itself after being applied to the hair is not prompted at all.

Accordingly, the present invention relates to a hair cosmetic which can be applied to the hair after shampooing and shampooed, so that the wet hair can be tangled and dried in a short time, and the dry hair can be given a bulky volume. Feeling, dry feeling.

As a factor in increasing the drying speed of hair after shampooing, it is important to "loose hair". That is, since the hair is loose, the contact area with the towel is increased when the towel is dried, so that the moisture of the hair is quickly absorbed by the towel, or dried by a hair dryer (naturally dried) When dry, the area of contact with air is increased to cause the moisture of the hair to quickly evaporate.

The inventors of the present invention have found that by using aromatic sulfonic acid and a cationic surfactant in a certain ratio in the rinse-type hair cosmetic used after shampoo, such as refining essence, moisturizing hair, etc. Compound, the complex compound can be a spacer between hairs, and as a volatile polyoxymethylene methyl polytrimethyl decane, the hair can be entangled and the adhesion of the adhering components on the hair can be weakened. Further, if these complexes which are spacers coexist with methylpolytrimethyloxane, the wet hair after the treatment is extremely loose, and there is no entanglement and the drying speed can be drastically improved.

[Examples]

Examples 1 to 13 and Comparative Examples 1 to 8

The moisturizers shown in Tables 1 and 2 were prepared and evaluated according to the following methods and standards.

(easy to loose hair bundle)

A hair bundle obtained by implanting a hair having a length of 30 cm at a density of 200 pieces/cm ² and an implant angle of 60° in a range of 6 cm × 6 cm square, using a commercially available bleach (made by Kao Corporation, Bubble Hair Color High) Bleach) Two bleaching treatments (5 mass times of bleaching agent applied to the hair and 30 minutes of treatment at room temperature) were used for the evaluation of the looseness of the hair bundle. After the prepared hair bundle was washed twice with ordinary shampoo, 1 g of the hair conditioner described in Tables 1 and 2 was applied, and rinsed with tap water. After rinsing, paper towels (Elleair Prowipe, manufactured by Daewoo Paper Co., Ltd., acrylic plate, hammer (1.3 kg of total weight of acrylic plate and hammer) were placed on the hair bundle having a water content adjusted to 10 g to remove excess water. The ease of dispersibility of the hair bundle and the ease of formation of a small hair bundle when the hair bundle was brushed by fingers were used as "easy looseness of the hair bundle", and five researchers conducted sensory evaluation. The evaluation was performed in five levels below, and the total scores of the five researchers were calculated.

5: Extremely easy to loose

4: Easy to loose

3: Slightly easy to loose (hard to evaluate)

2: Slightly difficult to loose

1: not easy to loose

(It is not easy to entangle in the drying process)

Using the above-mentioned hair bundle, sample processing was carried out in the same manner, and excess water was removed by a paper towel. Then, the hair bundle was set to face downward, and the hair dryer and the hair bundle were fixed in such a manner that the distance from the air outlet of the hair dryer (National company, TURBODRY 1300) to the center of the hair was 25 cm, and the warm air was blown from about 45° obliquely upward. The hair dryer is dried by brushing one finger every 4 seconds. At this time, five researchers conducted a sensory evaluation of "non-tangibleness" until they were completely dried. The evaluation was performed in five levels below, and the total scores of the five researchers were calculated.

5: Not tangled

4: Almost tangled

3: difficult to evaluate

2: A little easier to tangled

1: easy to entangle

(flavor)

Using the hair tresses described above, after the sample treatment was carried out in the same manner, the hair tips were turned down, and the hair bundles were completely dried by a hair dryer. After completely drying, five researchers conducted a sensory evaluation on the appearance of the hair bundle when placed on the table in an inverted state and the "fluffy feeling" when combed with a finger. The evaluation was performed in five levels below, and the total scores of the five researchers were calculated.

5: Very fluffy

4: Have a fluffy feeling

3: slightly fluffy

2: Not very fluffy

1: no fluffy feeling

(dry feeling)

Using the hair tresses described above, after the sample treatment was carried out in the same manner, the hair tips were turned down, and the hair bundles were completely dried by a hair dryer. After being completely dried, the smoothness, the soft feeling, and the feeling that the hair bundles were not attached to each other and easily loosened were used as a "dry feeling", and five researchers conducted a sensory evaluation. The evaluation was performed in five levels below, and the total scores of the five researchers were calculated.

5: Very dry feeling

4: Have a dry feeling

3: Slightly dry

2: Not very dry

1: no dry feeling

(the time until it feels dry)

Using the above-mentioned hair bundle, the sample was treated in the same manner and the excess water was removed with a paper towel. Then, the hair bundle was set to face downward, and the hair dryer (warm mode, air volume: weakest) was fixed to the hair bundle in such a manner that the distance from the air outlet of the hair dryer (National TURBODRY 1300) to the center of the hair was 25 cm. The hair dryer is dried while being combed once with fingers every 4 seconds. At this time, the quick-drying evaluation was performed from the time when the hair dryer was dried until the researcher judged that the hair was completely dry.
