Description

[Detailed Description of the Invention] The present invention provides a foam that has good foam stability, has a high lubricity improvement effect, and provides a good finish with excellent smoothness on the hair. This invention relates to a generated aerosol type hair cosmetic.

Conventional (U) Conventionally, silicones have been widely used in various hair care products as gloss imparting agents, lubricity improvers, feel improvers, and the like.

As a hair cosmetic using this silicone, for example, Japanese Patent Application Laid-Open No. 56-92808 contains a hydrophobic silicone material, a hair-setting polymer, an aerosol propellant, and water, and employs a specific filling method. An aerosol hair styling mousse and an aerosol hair-squiring mousse containing a hydroxylated polyolkalisiloxane emulsion, an aerosol propellant, and water have been proposed in JP-A-63-2918.

When silicone is added to hair cosmetics for the purpose of improving lubricity, among the various silicones, silicone oil is the most effective in improving lubricity. A certain dimethylpolysiloxane.However,
Dimethylpolysiloxane has an antifoaming effect, so
When applied to foam-forming aerosol type hair cosmetics, it has a disadvantage that the amount of the composition is limited because it has an adverse effect on the stability of the foam.

For these reasons, even if dimethylpolysiloxane is applied as a silicone to foam-forming aerosol hair cosmetics, it is not possible to increase the amount of the silicone, so it is difficult to comb, which is the lubricity in the vertical direction along the hair flow. It is possible to improve ease and smoothness. However, in order to achieve a smooth feel, which is the lateral lubricity (slipping quality) between hairs, other formulations, such as hair oil, are made by mixing high molecular weight dimethylpolysiloxane and low viscosity silicone. Although it is possible to impart fluidity and excellent lubricity, it is difficult to provide the same excellent effects as such other formulations of hair cosmetics.

Therefore, it is desired to develop a foam-generating aerosol type hair cosmetic composition that is highly effective in improving lubricity and can impart a smooth finish to the hair.

The present invention was developed in view of the above circumstances, and uses dimethylpolysiloxane, which has good foam stability, has a high lubricity improvement effect, and has an excellent effect of imparting a smooth feeling to hair. An object of the present invention is to provide a foam-forming aerosol type hair cosmetic.

As a result of intensive studies to achieve the above object, the present inventor, Feng, found that the viscosity of silicone at 25°C is 30,
By using high molecular weight dimethylpolysiloxane with a molecular weight of 000 centistokes or more, and by using this dimethylpolysiloxane together with a cationic polymer compound and an anionic surfactant, the foam can be stabilized even when dimethylpolysiloxane is mixed. It does not impair the properties of the hair and produces a highly stable foam when sprayed, and it has a high effect of improving lubricity not only in the vertical direction but also in the horizontal direction, and can give the hair a good finish with an excellent smooth feel. The present inventors have discovered that it is possible to obtain a foam-forming aerosol type hair cosmetic, and have thus come up with the present invention.

The present invention will be explained in more detail below.

The foam-generating aerosol type hair cosmetic according to the present invention has a composition of 25
It is made by using together a high molecular weight dimethylpolysiloxane having a viscosity of 30,000 centistokes or more at °C, a cationic polymer compound, and an anionic surfactant.

Here, the silicone used in the foam-forming aerosol type hair cosmetic of the present invention is dimethylpolysiloxane represented by the following formula (11), and has a viscosity of 30.0 at 25°C.
00 centistokes or more, preferably 100,000 centistokes or more
It is a high molecular weight dimethylpolysiloxane with centistokes or higher. The viscosity of dimethylpolysiloxane is 30.00
If it is less than 0 centistokes, the hair will be smooth,
Although it is possible to obtain the performance of giving a finish such as good combability,
The effect of imparting a slippery feel becomes insufficient, and lubricity that satisfies the object of the present invention cannot be obtained.

In addition, in the present invention, one type of the above-mentioned high molecular weight dimethylpolysiloxanes can be used alone or in combination of two or more types, and the blending amount is 1 to 20% (weight %) of the entire hair cosmetic. , hereinafter the same), particularly preferably from 4 to 10%.

If the amount is less than 1%, the effect of imparting a smooth feel to the hair may be insufficient, and if it exceeds 20%, the hair may become sticky and heavy.

Next, various cationic polymer compounds can be selected, such as ether of hydroxycellulose and glycidyltrimethylammonium chloride (trade name:
Leogard G [manufactured by Lion Corporation]), Polymer JR-30

Note that these cationic polymer compounds may be used alone or in combination of two or more.

Further, the amount of the cationic polymer compound to be blended is preferably 0.1 to 5%, particularly 0.2 to 3%, based on the total hair cosmetic composition. If the amount is less than 0.1%, both the stability of the foam and the smoothness of the hair finish tend to deteriorate.
If it exceeds %, the hair tends to become sticky and the smooth finish cannot be obtained.

Further, the anionic surfactant used in the present invention is not particularly limited, but for example, monosodium N-lauryl-glutamate (trade name: Amisoft LS-1)
