Description

Hair styling composition

Technical Field

The present invention relates to a hair styling agent composition. The present application claims priority of Japanese patent application No. 2017-088806 and Japanese patent application No. 2017-088807, patented in Japan on day 4 and 27 of 2017, the contents of which are incorporated herein.

Background

Hair styling compositions typified by hair water (hair water), hair gel (hair gel), hair spray (hair spray), hair cream (hair grease), and the like generally use a film-forming polymer as a hair styling base material. As the coating forming polymer, an anionic coating forming polymer, a cationic coating forming polymer, an amphoteric coating forming polymer, a nonionic coating forming polymer, and the like are used. In addition, various thickeners such as carboxyvinyl polymers are blended to adjust the hair styling composition to a desired viscosity (see patent documents 1 and 2).

Disclosure of Invention

Problems to be solved by the invention

Among the above coating-forming polymers, acrylic anionic coating-forming polymers are useful from the viewpoint of improvement in hair-setting retention and the like because they have moisture resistance and appropriate hardness. However, when the acrylic anionic film-forming polymer and the thickener (particularly, an anionic thickener) are blended together in a hair styling composition, it is known that the viscosity is lowered with time.

Conventionally, a method of compounding sodium ethylenediaminetetraacetate or the like to suppress a decrease in viscosity of a thickener and stabilize a preparation has been known. However, in a hair styling composition in which an acrylic film-forming polymer and a thickener are blended, even if sodium ethylenediaminetetraacetate is blended, the effect of suppressing the decrease in viscosity with time is insufficient.

Accordingly, an object of the present invention is to provide a hair styling agent composition in which an acrylic coating film-forming polymer and a thickener are blended and a decrease in viscosity with time is suppressed.

Examples 1 to 12 and comparative examples 1 to 3

Each hair styling composition was prepared according to the composition described in table 1. The hair styling compositions obtained in examples 1 to 12 and comparative examples 1 to 3 were all in the form of gels.

[ evaluation of decrease in viscosity ]

Approximately 50g of the hair styling agent compositions of the examples and comparative examples were filled in a white can container (capacity 50mL), and stored in a sealed state in a constant temperature bath at 5 ℃ and 40 ℃ for 4 weeks. The consistency (25 ℃) of the samples stored at 5 ℃ for 4 weeks (5 ℃ C. stored samples) and at 40 ℃ for 4 weeks (40 ℃ C. stored samples) was measured, respectively. Consistency (25 ℃) using a thickener

The consistence of the flat joint [ Sun Scientific Co., Ltd., product name "RHEO METER"]The measurement was carried out under the conditions of 25 ℃, speed 60 mm/min and stroke 20 mm. As a result, the hair styling agent compositions of examples 1 to 12 had a consistency of the [40 ℃ stored sample (25 ℃) and a consistency of the 5 ℃ stored sample (25 ℃)]Is 0.87 or more. On the other hand, the hair styling agents of comparative examples 1 to 3 had a consistency of [40 ℃ storage sample (25 ℃)/a consistency of 5 ℃ storage sample (25 ℃)]Is 0.81 or less. In addition, in the hair styling agents of examples 1 to 12, the viscosity of the 40 ℃ storage sample was not substantially reduced from that of the 5 ℃ storage sample in visual observation, while the viscosity of the 40 ℃ storage sample of the hair styling agent of comparative examples 1 to 3 was significantly reduced from that of the 5 ℃ storage sample.

As shown in the above results, the reduction in viscosity was sufficiently suppressed in the hair styling compositions (examples 1 to 12) containing the component a, while the reduction in viscosity was observed in the hair styling compositions (comparative examples 1 to 3) containing no component a. In the above comparative examples, component G or component E was added in place of component a, but the effect of suppressing the decrease in viscosity with time of the hair styling agent composition of the present invention was not sufficiently exhibited only by using these components.

[ evaluation of color tone and odor ]

In addition to the evaluation of the above-mentioned viscosity reduction, the hair styling agents of the examples and comparative examples were subjected to sensory evaluation of the color tone and odor of the 40 ℃ stored sample and the 5 ℃ stored sample by visual sense and olfactory sense. Evaluation was performed by 3 professional judges. As a result, in examples 1 to 5 and 7 to 12 and comparative example 3, the color tone of the 40 ℃ storage sample and the 5 ℃ storage sample changed to such an extent that they could not be recognized by the separation evaluation. On the other hand, in example 6 and comparative examples 1 to 2, yellowing was observed in the samples stored at 40 ℃ to a degree clearly recognizable by the separation evaluation as compared with the samples stored at 5 ℃. In examples 1 to 12 and comparative example 3, the odor change in the 40 ℃ storage sample and the 5 ℃ storage sample was such that the odor change could not be recognized by the separation evaluation. On the other hand, in comparative examples 1 to 2, the odor was observed in the 40 ℃ stored sample to a degree clearly recognizable by the separation evaluation as compared with the 5 ℃ stored sample.
