Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an aerosol foam that has excellent conditioning effects, particularly antistatic properties, has low corrosivity to metal containers, and can generate fine-grained and stable foam-like ejections. Regarding hair cosmetics.

[Problems to be Solved by the Prior Art and the Invention] Conventionally, quaternary ammonium salts such as dialkyldimethylammonium chloride and alkyldimethylammonium chloride have been used as active ingredients in hair cosmetics. In this case, the quaternary ammonium salt not only imparts flexibility to the hair, but also has the effect of adsorbing to the anion moiety of the hair, reducing electrostatic charge, and improving combability and smoothness. However, recently, aerosol type hair cosmetics have become preferred, but quaternary ammonium salts are corrosive to metals.
This poses a problem when filling aerosol containers.

Moreover, when it is made into a foam, it is difficult to apply a quaternary ammonium salt to an aerosol foam hair cosmetic because the texture and stability of the foam are impaired.

In addition, aerosol foam hair cosmetics conventionally include polysiloxanes such as dimethylpolysiloxane to provide smoothness and ease of combing, and higher alcohols and ester oils to improve moisturizing properties. However, these oil-based components have a weak antistatic effect and do not provide satisfactory antistatic properties (therefore, there are some oil-based components that have the above effects and also have excellent antistatic properties). Hair cosmetics are desired.

The present invention has been made in view of the above circumstances, and is an aerosol foam hair cosmetic that provides good conditioning effects to the hair, particularly excellent antistatic properties, has low container corrosion resistance, and can generate fine-textured and stable foam. The purpose is to provide fees.

[Means and effects for solving the problem] The present inventors,
As a result of intensive studies to achieve the above objective, we found the following general formula (1) (wherein R1 is a branched or linear alkyl group or alkenyl group having 1 to 22 carbon atoms, and A is a carbon Number 1~
10 branched or linear alkylene groups or alkenylene groups, and m is 0 or 1. Moreover, n is an integer of 1-5. ) When a hair cosmetic containing a guanidine derivative having an amide group in the molecule or a salt thereof as an active ingredient is made into an aerosol, it has excellent antistatic properties, is less corrosive to metal containers, and has a smooth texture. It was found that fine and stable foams can be produced.

That is, the present applicant has developed a hair cosmetic that has high adsorption of active ingredients to the hair and imparts excellent flexibility to the hair.
The present inventors devised a hair cosmetic containing the compound of general formula (1) as an active ingredient (Japanese Patent Application No. 63-320075). When the compound is filled into an aerosol container with water and a propellant and used in the form of an aerosol foam, it does not corrode the metal container used as the aerosol container, and the resulting foam has a fine texture and is stable, and it is not harmful to hair. It has been discovered that excellent antistatic properties can be imparted, and the present invention has been completed.

The present invention will be explained in more detail below.

The aerosol foam hair cosmetic of the present invention contains a propellant and water, and is of the type that generates foam-like ejecta when used. Contains salt.

Here, the substituent R1 in formula (1) has 1 to 22 carbon atoms,
Preferably it is a 11-19 branched or straight-chain alkyl group or alkenyl group, for example, C+ +1 (zs-+
C+Jzs-+C+Jzt-+C+aHzv-+C+s
Hs+-+c, 6H33-・C+Jzs-, (C@rt
7) Groups such as 2C-4-C2H5Cl 5H30 are preferred.

Further, substituent A has 1 to 1 carbon atoms, preferably 2 to 6 carbon atoms.
A branched or linear alkylene group or alkenylene group, such as a methylene group, ethylene group, propylene group, butylene group, pentylene group, hexylene group, isopropylene group, 2-pentenyl group, 2-ethylbutylene group, etc. m is l or 0.

Note that n is an integer of 1 to 5.

Furthermore, the guanidine derivative of formula (1) is usually formulated in the form of a salt, specifically inorganic acid salts such as hydrochloride, organic acids such as glycolate, acetate, citrate, and acidic amino acid salts. It can be used as a salt, but from the viewpoint of solubility in water, hydrochloride is preferable when using an inorganic acid salt, and glycolate is preferable when using an organic acid salt.

In this case, the guanidine derivative of formula (1) and its salt are:
One type may be blended alone, or two or more types may be used in combination.
In addition, the blending amount is not particularly limited, but the total amount is 0.0
It is preferably 5 to 10% (by weight, hereinafter the same), particularly 0.1 to 5%.

If the amount is less than 0.05%, the antistatic property may not be sufficient, and if it exceeds 10%, when applied to hair, the finish will be sticky and heavy, and the texture and stability of the foam may be impaired.
