Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair spray composition containing a hair fixing polymer compound, and more specifically, it has an excellent antistatic effect on hair and does not cause frizz when used. The present invention relates to a hairspray composition that is free of corrosion and has low corrosion resistance to metal containers.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Various hair spray compositions containing hair-fixing polymer compounds that have a set-maintaining effect have been proposed, but in order to fix the hair and maintain the condition for a long time, it is necessary to prevent the hair from becoming electrostatically charged. Here, electrification of hair is caused by brushing or the like, and hair that has been damaged by a perm or the like is particularly susceptible to electrification. Additionally, the tips of the hair are more likely to be charged with static electricity because they are more likely to be damaged by weathering than the roots. If the hair fibers are strongly charged, even if a hairspray having a strong centrifugal force is used, a sufficient centrifugal effect cannot be obtained due to electrostatic repulsion between the hair fibers. Particularly, the tips of the bristles, which are heavily charged, tend to cause springiness, which can be a hindrance to maintaining cents.

Conventionally, methods to solve such problems are
A method is known in which a quaternary ammonium salt, typified by dialkyldimethylammonium chloride and alkyltrimethylammonium chloride, is blended into a hairspray composition. However, quaternary ammonium salts are highly irritating to the skin, and when fine particles sprayed from a hairspray containing them are inhaled, they irritate the respiratory mucous membranes and cause nausea. Furthermore, since quaternary ammonium salts are corrosive to metals, hairspray compositions containing them tend to corrode metal containers.

The present invention has been made in view of the above circumstances, and provides a hair spray composition that has an excellent antistatic effect on hair, does not cause stiffness during use, and has low corrosion resistance to metal containers. The purpose is to

[Means to solve the problem]

As a result of intensive studies to achieve the above object, the present inventors have developed a hair spray composition containing a hair fixing polymer compound according to the following general formula (1) (wherein R1 is the number of carbon atoms). A is a branched or linear alkyl group or alkenyl group having 1 to 22 carbon atoms, A is a branched or linear alkylene group or alkenylene group having 1 to 10 carbon atoms, and m is O
Or 1. Moreover, n is an integer of 1-5. ) It has been found that when guanidine derivatives having an amide group in the molecule or their salts are blended, they have excellent antistatic effects, do not cause lumpiness during use, and are less corrosive to metal containers.

That is, the present applicant has previously developed a hair cosmetic in which the active ingredient is highly adsorbed to the hair and imparts excellent flexibility and moisturizing properties to the hair, using the compound of general formula (1) as an active ingredient. The present inventors proposed a hair cosmetic (Japanese Patent Application No. 63-320075), but as a result of further investigation, the above general formula (1)
) When the compound is made into a hair spray composition together with a hair-fixing polymer compound, it does not corrode the metal container used as a spray container, does not cause any stiffness during use, and has excellent electrostatic properties for hair. It has been discovered that it is possible to impart preventive properties, and the present invention has been completed.

The present invention will be explained in more detail below.

The type of hair fixing polymer compound used in the hair spray composition of the present invention is not limited, and any polymer compound conventionally used to impart centrifugal force to hair can be used. , Specifically, for example, the following (1)

Among these polymer compounds, those having acid groups are preferably used after being neutralized with a suitable alkali agent. Further, these polymer compounds may be used alone or in combination of two or more.

Although there is no particular limitation on the amount of the above-mentioned polymer compound, it is preferably 0.1 to 10% (weight %, same hereinafter) of the entire composition. If it is less than 0.1%, the setting power of the hair may decrease, and if it exceeds 10%, the hair will become stiff.
Stickiness may occur.
