Description

Hair cosmetics

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 and 2 disclose a hair conditioner that is excellent in touch and that contains a cationic surfactant, a higher alcohol, an oil and fat, silicone, and the like.

Patent Document 2 discloses a hair conditioning composition in which volatile silicone M3T (methyltrimethicone), a nonvolatile silicone derivative and a cationic surfactant are combined.

Patent Document 3 discloses an optically transparent hair treatment agent containing a hydrophobic silicone compound and a hydrophilic silicone compound, as well as various active agents and polymers.

The present invention also provides a hair treatment method in which the above-described hair cosmetic is applied to the hair and washed away with water.

Detailed Description of the Invention

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 among 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.

However, conventional hair treatment agents leave silicones and oils on the hair in order to give the hair a smooth and moist feeling. However, since these have stickiness, each hair is separated. There is a problem that it takes time to dry the hair after washing.

Therefore, the present invention makes it easy to disperse each piece of wet hair, regardless of the type of cationic surfactant contained, by washing it after applying it to the hair after shampooing. The present invention relates to a hair cosmetic that can be dried over time and has excellent smoothness during rinsing.

In addition, the above-mentioned patent document 2 describes that drying after applying a hair conditioning composition to hair is quick. However, the fast-drying hair conditioning composition specifically disclosed in the literature is only a type that does not wash away, and the effect of “fast drying after application” in the present invention is also fast drying of the hair conditioning composition itself. That's what it means. Therefore, this document does not suggest at all the speed with which water is dried from hair that has been applied to the hair and then washed away and sufficiently wet.

“Hair dispersal” is important as a factor to increase the drying speed of hair after washing. 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.

In the hair cosmetics of the type to be used after shampooing, such as hair rinse, hair conditioner, etc., the present inventors have used an amino-polyether co-modified silicone having a specific structure and a volatile silicone in combination to produce an adhesive component on the hair. It has been found that the amount of adsorption is reduced and the bulky adhesive component hardly adheres to the hair. As a result, the present inventors have found that the adhesiveness of each hair can be weakened, wet hair after treatment becomes extremely easy to disperse, and the drying speed can be dramatically improved without tangling.

Evaluation was performed in the following five stages, and the total score of five people was calculated.
5: Very easy to disperse 4: Easy to disperse 3: Not to say 2: Slightly difficult to disperse 1: Difficult to disperse

"Difficult to get tangled during dryer drying"
After evaluating the above “Ease of dispersal of hair bundles”, install the tresses used for the evaluation downward, and the distance from the outlet of the dryer (National, TURBODRY1300) to the hair center of the hair tress is 25 cm. The dryer was fixed so that the warm air hits from about 45 ° diagonally. Next, the dryer was dried once every 4 seconds while passing the finger through the tress. 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 of them 2: Slightly entangled 1: Slightly entangled

(Speed of drying)
After washing the evaluation tress made by the above method with a plain shampoo, lightly drain it, apply 1g of the conditioner shown in Table 1, rinse with tap water, let it drain naturally for 60 seconds, and then place a paper towel on the tress. (Daiou Paper Co., Ltd., Erière Pro Wipe), acrylic plate, weight (total weight of acrylic plate and weight 1.3 kg) were placed in order to remove excess water.
This hair tress was placed face down, and the dryer (low warm air mode: 600 W) was fixed so that the distance from the outlet of the dryer (manufactured by Tescom, Nobby NB2501) to the hair center of the hair tress was 45 cm. Next, the dryer was dried while passing a finger once every 4 seconds. At this time, the time (seconds) from the start of drying the dryer until the researcher was able to determine that the hair was completely dried was measured. This operation and measurement were repeated three times, and the average value was used for quick drying evaluation.
