Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition used as a hair spray, and more particularly to a hair cosmetic composition which does not have a peculiar irritating odor or a strange odor during use and can comfortably set hair.

[0002]

2. Description of the Related Art Heretofore, a hair spray has been used for the purpose of imparting hair styling power and set holding power when setting hair. The hair spray usually comprises a hair-fixing film-forming resin as a main component, and the other components, such as ethanol as a solvent and a propellant.

[0003]

The above hair spray is
When ethanol as a solvent and a propellant are sprayed, they are vaporized and scattered in the air, which causes an irritating odor and a strange odor felt by the user, which has become a problem. However, hair sprays have gained wide acceptance among consumers due to their exceptional performance in fixing hair and retaining style. At present, in order to reduce the irritating odor and the offensive odor as much as possible, methods such as reducing the raw material odor and masking with a fragrance have been performed, but there is no remarkable effect. In recent years, fragrance-free hair sprays have been marketed, but the fact is that the raw material odor and the pungent odor of ethanol have not been reduced.

Further, JP-A-61-161214 describes a hair spray containing a specific organic silicone resin, a volatile silicone oil and a propellant gas. The hair spray is applied to hair. The purpose is to impart good set holding power and excellent luster and smoothness, and no consideration is given to the suppression of the raw material odor and the pungent odor of ethanol.

Therefore, an object of the present invention is to provide a hair cosmetic composition which does not have a peculiar irritating odor or a strange odor when used and which can comfortably set hair.

[0006]

Means for Solving the Problems As a result of intensive studies, the present inventors have found that the use of a specific volatile substance, a specific hair-fixing film-forming resin, and a liquefied gas or a compressed gas can achieve the above-mentioned object. In addition to achieving the above, it was found that the drying speed at the time of spraying, which is an important performance as a hair spray, is remarkably increased, the usability of the spray is improved, and the setting can be done instantly, so that the style holding power can be maintained.

The present invention has been made based on the above-mentioned findings. (A) The general formula (I) of the following [Chemical formula 3] (the same as the general formula (I) of the above [Chemical formula 1]) or the following 4] at least one volatile silicone oil represented by the general formula (II) (the same as the general formula (II) of [Chemical Formula 2]) and / or at least one volatile hydrocarbon having a boiling point of 0 to 40 ° C., A hair cosmetic comprising (B) a water-soluble polymer compound and (C) a propellant.
