Embodiment 1～3

[0135] A hair cosmetic (pump spray) having the composition shown in Table 1 was prepared by a usual method. With regard to the prepared hair cosmetics, hair management properties, hair restorative properties, stickiness, and stiffness were evaluated. The results are shown in Table 1 together.

[0136] (Evaluation method)

[0137] (1) Hair management

[0138] Hair conditioning was carried out by 10 expert judges using each hairspray, and hair conditioning property was sensory-evaluated based on the following criteria. The results were expressed as the average value of the evaluation points.

[0139] (evaluation criteria)

[0140] 5: very good

[0141] 4: Good

[0142] 3: slightly better

[0143] 2: slightly worse

[0144] 1: Poor

[0145] (2) Hair restorative property

[0146] Hair conditioning was carried out by 10 expert judges using each hairspray, and the hair restorative property after spraying in an environment of 25° C. and 65% RH for 9 hours was sensory evaluate...

Embodiment 4～12 and comparative example 1～5

[0166] Use the usual method to prepare the hairspray collagen solution shown in Table 2, and together with LPG (0.15MPa, 20°C) as the propellant, fill it with the following Aerosol container with valve and button to make aerosol hair cosmetics. The pressure in the container was 0.23 MPa at 25°C.

[0167] Valve: Rod diameter Φ0.41mm, lower housing diameter Φ0.64mm x mist discharge hole diameter Φ0.41mm.

[0168] Button: Diameter Φ0.46mm (MB, Concape)

[0169] (Precision Valve, Japan)

[0170] About the obtained hair cosmetics, it carried out similarly to Examples 1-3, and evaluated hair management property, hair restorative property, stickiness and stiffness. The results are shown in Table 2 together.

[0171]

[0172] In the following examples, the stock solution viscosity was measured using a B-type viscometer manufactured by Toki Sangyo Co., Ltd. (rotor: BL adapter, rotation speed: 30 rpm, 60 seconds, 30° C.). The average particle size of the sprayed droplets is meas...

Embodiment 13～17 and comparative example 6～9

[0174] Using the usual method, prepare the hairspray collagen solution shown in Table 3, together with LPG (0.15MPa, 20°C) as the propellant, fill in the following liquid according to the stock solution / propellant (mass ratio) shown in Table 1 Aerosol container with valve and button. The pressure in the container was 0.23 MPa at 25°C.

[0175] Valve: Rod diameter Φ0.41mm, lower housing diameter Φ0.64mm x mist discharge hole diameter Φ0.41mm.

[0176] Button: Diameter Φ0.46mm (MB, Concape)

[0177] (manufactured by Precision Valve Japan)

[0178] In addition, the adhesive force of a dry residual component was measured as follows.

[0179] (test methods)

[0180] Put the aerosol-type hair cosmetics in a round flask, depressurize it to the range of 15mmHg to 20mmHg with a rotary evaporator, and quantify it at 60°C to remove volatile components to obtain dry residual components. 10% by mass ethanol solution of the remaining components; in an environment of 25° C. and 65% RH, ...

Abstract

Disclosed is a hair cosmetic which comprises the components (A) and (B) shown below, and contains a compound having two or more hydroxyl groups in the molecule, having a molecular weight of 62 to 1000and taking a liquid state at 30 DEG C in an amount of less than 1 mass%. (A) At least one copolymer selected from the following (A1) and (A2): (A1): a copolymer comprising (a) 30 to 80 mass% of a (meth)acrylamide monomer, (b) 2 to 50 mass% of a (meth)acrylamide monomer, (c) 0 to 30 mass% of a (meth)acrylic acid ester monomer or a (meth)acrylamide monomer, and (d) 0 to 40 mass% of a (meth)acrylicacid ester monomer; and (A2): a copolymer comprising (a) 30 to 80 mass% of a (meth)acrylamide monomer, (b) 5 to 45 mass% of a (meth)acrylic acid ester monomer, (c) 2 to 30 mass% of a (meth)acrylic acid ester monomer or a (meth)acrylamide monomer, and (d) 0 to 30 mass% of a (meth)acrylic acid ester monomer. (B) At least one member selected from a long-chain alkyl glyceryl ether, a fatty acid monoglyceride, a fatty acid diglyceride and a fatty acid triglyceride.

Description

technical field [0001] The present invention relates to a hair cosmetic. Background technique [0002] Heretofore, aerosol-type hair cosmetics for hair conditioning are generally hair cosmetics that fix hairstyles by utilizing the anchoring force of hair conditioning polymers. However, once the hair is fixed, the hair cannot be re-styled, and the hair after the grooming becomes stiff, which causes dissatisfaction such as stiff hair. [0003] On the other hand, in the case of setting agents such as pomade, since the hair style is maintained by the adhesive force of the oil, the hair will not become hard and the natural style can be obtained, and the hair can also be reorganized, but the stickiness caused by the oil Combined force causes the stickiness. Furthermore, it is extremely weak compared with the fixing force of the polymer for hair conditioning, and it is difficult to maintain a desired hairstyle for a long period of time. [0004] A hair cosmetic containing a poly...
