Next, the manufacturing method of hair cosmetics is demonstrated.
In the present embodiment, the hair cosmetic preparation, for example, prepares an oil phase containing the components (C) and (D), and heats it to the melting point or higher of the component (D);
A step of uniformly mixing the oil phase with an aqueous phase heated to the melting point of component (D) or higher to obtain an emulsion;
Mixing and dispersing components (A), (B) and (E) in the course of cooling the emulsion to room temperature;
Cooling the emulsion to room temperature;
including.

In the hair cosmetic obtained in the present embodiment, the cationic surfactant of component (C) remains efficiently on the hair, and the slipperiness is improved by the silicone of components (A) and (B).
In the present embodiment, the components (A) to (E) and water are used in combination, and the components (A) to (E) are used in a specific range, so that the hair wet with water is removed from towel dry. It is possible to suppress entanglement during the drying, promote the dispersion between the hairs, and shorten the drying time.

  Here, according to the study of the present inventor, “hair scattering” is important as a factor for increasing the drying speed of the hair after washing. That is, when the hair is dispersed, the contact area between the hair and the towel increases when the towel is dried, and the moisture of the hair is quickly absorbed by the towel. In addition, not only when drying a dryer, but also when drying naturally, the area of contact with air increases and the moisture of the hair evaporates quickly.

  On the other hand, in hair cosmetics such as hair conditioners, by adding a conditioning component, the lubricity of the hair can be improved, so that the effect of suppressing crossover and tangling of the hair and preventing entanglement is improved. . However, the addition of the conditioning component improves the adhesiveness between the hairs, so that the hairs are prevented from separating and becoming separated, and the ease of drying of the hairs is suppressed.

That is, since the lubricating component blended in the hair cosmetic has adhesiveness, there was a trade-off relationship between imparting the lubricating property to the hair by the lubricating component and suppressing the adhesiveness between the hairs.
Then, when this inventor examined so that the lubricity provision to hair and the suppression of the adhesiveness between hair might be made compatible, by using combining a component (A)-(E), it becomes a tangle of hair. It has been found that the adhesiveness due to the adhering components on the hair can be weakened while loosening the hair, the wet hair after treatment becomes very easy to disperse, and the drying speed can be drastically improved with little tangling of the hair.

  That is, according to this embodiment, it is possible to achieve both imparting lubricity to hair and imparting non-tackiness. More specifically, the components (A) and (E) are combined so that the hairs are easily separated from each other, and the components (A) to (E) are kept to a minimum in the hair, so that a towel can be dried or a dryer, etc. In addition to being able to effectively suppress entanglement of wet hair such as during drying, the adhesion between the hairs can be suitably suppressed to improve the dispersibility between the hairs. For this reason, for example, it becomes possible to obtain the quick-drying and the entanglement preventing effect that the user can feel.

  Further, the hair cosmetic composition of the present embodiment is preferably used after being applied to the hair and washed away, and examples thereof include those used in the bathroom such as hair rinse, hair conditioner, hair treatment, hair pack and the like. It is done.

  In order to perform hair conditioning using the hair cosmetic composition of the present embodiment, the hair cosmetic composition of the present embodiment may be applied to the hair and then washed off with water. Thereby, the hair bundle becomes easy to spread at the time of towel drying after rinsing, and wet hair can be dried in a short time. Further, for example, it is possible to impart a smooth and moist feeling to the hair after drying.

  As mentioned above, although embodiment of this invention was described, these are illustrations of this invention and various structures other than the above are also employable.

Excess water was removed (processing time was 10 seconds).
Next, set the hair tress downward and fix the dryer and hair tress so that the distance from the blower outlet of the dryer (Panasonic 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 “no entanglement in the drying process” until the film was completely dried. The evaluation was based on the following criteria and expressed as a total score of five evaluation points.
The criteria for sensory evaluation are as follows (the table shows the total score of five people).
Hard to get tangled: 5
Slightly less tangled: 4
Neither: 3
Slightly entangled: 2
Easy to get tangled: 1

(Time to feel dry)
Using the above-mentioned tres, the sample was processed according to the evaluation method for the absence of entanglement in the drying process, and excess water was removed with a paper towel.
Next, place the hair tress downward and fix the hair tress (dry air mode, air volume: weakest) and the hair tress so that the distance from the blower outlet of the dryer (Panasonic TURBODRY1300) to the center of the hair is 25 cm. Then, the dryer was dried while passing the 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.
About the hair processed with the hair conditioner of Table 1 and Table 2, the drying time was set to 300 seconds or less as the pass.

In Table 1 and Table 2, the following were used as each component.
* 1 Methyltrimethicone: TMF-1.5, manufactured by Shin-Etsu Chemical Co., Ltd. * 2 Cyclopentasiloxane: SH245, manufactured by Shin-Etsu Chemical Co., Ltd. * 3 Trisiloxane: KF96 1cs, manufactured by Shin-Etsu Chemical Co., Ltd. * 4 Stearamidopropyldimethylamine : NIKKOL Amidoamine MPS, manufactured by Nikko Chemicals * 5 Behentrimonium methosulphate: Incroquat behenyl TMS-50-PA- (MH), Croda Inc. * 6 Cetrimonium chloride: Cotamin 60W, manufactured by Kao Corporation * 7 Stearyl alcohol: Calcoal 8098, manufactured by Kao Corporation * 8 Cetanol: Calcoal 6098, manufactured by Kao Corporation

  In each example, since the components (A) to (E) are used in combination within a specific range, the hair bundles are more easily separated when drying the towel than those of the comparative examples. In addition to suppressing hair entanglement, the time to dry with a dryer could be shortened.
