The aerosol spray hair styling agent is preferably an aerosol spray hair styling agent in which the aerosol spray hair styling composition is sprayed in the form of a mist.

  The aerosol spray hair styling agent includes an aerosol spray container, the aerosol spray hair styling composition described above, and a propellant. The aerosol spray container has a spray nozzle. In the aerosol spray hairdressing agent, the aerosol spray hairdressing composition and the propellant are filled in the aerosol spray container. The aerosol spray hair styling composition is a composition excluding the propellant in the aerosol spray hair styling agent, among the fillings filled in the aerosol spray container.

  Examples of the propellant include dimethyl ether, isobutane, liquefied petroleum gas, and nitrogen gas. As for the said propellant, only 1 type may be used and 2 or more types may be used together.

  From the viewpoint of further preventing clogging, the propellant preferably contains at least one of liquefied petroleum gas and dimethyl ether, and more preferably contains liquefied petroleum gas.

  The aerosol spray hair styling agent can be prepared by a known method. As an aerosol spray hair preparation method, the aerosol spray hair preparation composition or each compounding component contained in the aerosol spray hair preparation composition is filled in an aerosol spray container, and the aerosol spray container is clinched by an aerosol valve. After that, a method of filling the propellant from the stem and mounting an injection button suitable for the stem can be mentioned.

  In the total 100% by mass of the hairdressing composition according to the present invention and the propellant, the content of the aerosol spray hairdressing composition is preferably 10.0% by mass or more, more preferably 20.0% by mass or more, preferably Is 70.0 mass% or less, More preferably, it is 60.0 mass% or less, More preferably, it is 50.0 mass% or less. When the content of the hairdressing composition according to the present invention is not less than the above lower limit and not more than the above upper limit, the discharge property is further improved.

  In a total of 100% by mass of the hairdressing composition and the propellant according to the present invention, the content of the propellant is preferably 30.0% by mass or more, more preferably 40.0% by mass or more, and further preferably 50.% by mass. It is 0 mass% or more, preferably 90.0 mass% or less, more preferably 80.0 mass% or less. When the content of the propellant is not less than the above lower limit and not more than the above upper limit, the discharge property is further improved.

  Hereinafter, the present invention will be specifically described with reference to Examples and Comparative Examples. The present invention is not limited only to the following examples.

  In the examples and comparative examples, the following components were used.

(Ingredient (A))
Silylated silica (product name “AEROSIL RX300-5”, manufactured by Nippon Aerosil Co., Ltd., dimethylsiloxylated silicic anhydride)

(Ingredient (B))
Silica (made by Nippon Aerosil Co., Ltd., trade name “AEROSIL 200”)

(Ingredient (C))
Cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol (manufactured by Nippon Seika Co., Ltd., trade name “Neosolue-Aculio”)
(Eicosanedioic acid / tetradecanedioic acid) polyglyceryl-10 (manufactured by Nippon Seika Co., Ltd., trade name “Neosolue-Aqua”)

(Other)
Dipropylene glycol (trade name "Dipropylene glycol DPG-FC" manufactured by Asahi Glass Co., Ltd.)
Cetyl ethylhexanoate (trade name “CIO-N” manufactured by Nippon Surfactant): Oil content not corresponding to component (C) Hydrogenated polyisobutene (trade name “Marcazole R” manufactured by Maruzen Petrochemical Co., Ltd.): component (C) Not equivalent oil Perfume Ethanol

(Examples 1-8 and Comparative Examples 1-6)
The blending components shown in the following Tables 1 and 2 were blended (the blending unit was mass%) to prepare an aerosol spray hair conditioner composition (stock solution) having the composition shown in Tables 1 and 2 below. The obtained aerosol spray hairdressing composition (stock solution) was filled in an aerosol container (capacity 95 ml). Next, after the aerosol valve was clinched in the container, a propellant (liquefied petroleum gas) was filled from the stem, and a button suitable for the stem was attached to prepare an aerosol spray hairdressing agent. The total amount of the stock solution and the propellant was 30 g, and the mass ratio of the stock solution and the propellant was 40:60.

(Evaluation)
Four expert panels performed the following evaluations.

(Test Example 1: Evaluation of hair styling power)
Spray each aerosol spray hair styling agent evenly onto the hair of a short hair wig (Lesson Mannequin: Eucalyptus Japan), and adjust the hair so that the hair near the top of the head rises upward from the base of the hair. gave. At that time, the hair styling power is good when the hair is raised firmly at an angle of 60 ° or more upward from the root (◯), and the hair styling power is poor when the hair cannot be raised at an angle of 60 ° or more (X) was determined. In addition, the said angle is 90 degrees when it stands | starts up perpendicularly.

(Test Example 2: Evaluation of good touch)
After Test Example 1 (Evaluation of hair styling power), the raised hair was touched with a hand to evaluate the touch. When the hair was not sticky or stiff, the touch was good (◯), and when the hair was sticky or stiff, the touch was evaluated as poor (x).

(Test Example 3: Evaluation of moisture resistance)
Spray each aerosol spray hair styling agent evenly onto the hair of a short hair wig (Lesson Mannequin: Eucalyptus Japan), and adjust the hair so that the hair near the top of the head rises upward from the base of the hair. gave. The hair after styling was allowed to stand for 1 hour in a thermo-hygrostat set to high temperature and high humidity conditions (35 ° C., 80% RH). The degree of rising of the hair after standing (after the moisture resistance test) was compared with the degree of rising of the hair in Test Example 1 (immediately after styling). Good moisture resistance when the hair rising angle after the moisture resistance test is almost the same as the hair rising angle immediately after hair styling (◯). The hair rising angle after the moisture resistance test is the hair rising angle just after hair styling. Moisture resistance is slightly good (△) when the angle is more than half of the angle of, and when the hair rising angle after the moisture resistance test is less than half of the hair rising angle immediately after hair styling, the moisture resistance is poor (× ).

(Test Example 4: Evaluation of washing off)
After Test Example 1, the hair bundle of the wig was washed with lukewarm water using a shampoo (trade name “Lucido Shampoo”, manufactured by Mandom Co., Ltd.), then dried, and the dried hair was touched and washed off by hand. Evaluated. When there was no squeak or stickiness on the hair after washing, it was judged that the wash-off was good (◯), and when the hair after washing had a squeak or stickiness, the wash-off was judged as poor (×).

  The results are shown in Tables 1 and 2 below.
