Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hair cosmetic, and more particularly to a hair cosmetic which has excellent low-temperature stability and is suitably used as a hair water, a hair styling foam, a hair spray and the like.

[0002]

2. Description of the Related Art Conventionally, many hair cosmetics contain a cationic surfactant for the purpose of imparting a smooth feel to hair and preventing the spread of hair due to static electricity. Various compositions of hair cosmetics containing a cationic surfactant have been proposed (JP-A-58-188812, JP-A-59-227994).
No., JP-A-63-22513, JP-A-62-2672
No. 20, JP-A-1-221308, JP-A-3-128
309, JP-A-3-223208). However, there has been no proposal which mentions the storage stability of such a cationic surfactant, especially the low-temperature stability, although a higher-performance cationic surfactant tends to precipitate at a lower temperature. In addition, none of the above proposals mention convenience or the like when applied to hair.

[0003] On the other hand, in recent years, the convenience of hair application and the cleanliness of removing hair cosmetics from containers by removing only the amount used and preventing the hands from directly touching the hair cosmetics remaining in the containers. From the point of view, various hair cosmetics are prepared and used in dosage forms such as sprays and foams. However, since the spray agent and the foam agent are used by being filled in a spray container having a smaller diameter than a wide-mouth pump container filled with, for example, ordinary hair rinse and hair conditioning, and a former container using a mesh, it is assumed that Even if an attempt is made to prepare a hair cosmetic containing a cationic surfactant as a spray or a foam, if a precipitate is generated by storage in a container,
This causes clogging of the container, which is a serious problem in practical use.

[0004] The present invention has been made in view of the above circumstances, and is intended to improve the low-temperature stability of a specific cationic surfactant and to provide a sufficient effect of applying the cationic surfactant to hair. Another object of the present invention is to provide a hair cosmetic which is excellent in usability when applied to hair.

[0005]

Means for Solving the Problems and Embodiments of the Invention The present inventors have conducted various studies in order to solve the above-mentioned problems, and as a result, as shown in Examples described later, the use of cationic surfactants Above all, when a specific betaine type surfactant represented by the following general formula (3) or (4) is used in combination with a specific cationic surfactant represented by the following general formula (1) or (2), It has been found that the storage stability of the surfactant is improved, and that precipitation under low-temperature storage can be sufficiently prevented, and therefore, hair cosmetics having such a composition are prepared into spray formulations and foam formulations, By filling in a spray container and a former container, clogging of the container does not occur, and not only a sufficient effect on the hair by the addition of the cationic surfactant is obtained, but also a And it found that hair cosmetic which is excellent in flight can be obtained, and have completed the present invention.
