Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair mascara, and more specifically, it is a kind of temporary hair coloring agent also called a temporary color, and is mainly used for partial dyeing of hair on the hairline depending on a particular use form. Regarding

[0002]

2. Description of the Related Art Temporary hair coloring agents are different from oxidative hair coloring agents called hair dyes and acidic hair coloring agents marketed as acidic hair colors or hair nail polishes.
It simply colors the hair with a pigment coating. It is widely used, for example, for hiding white hair or for coloring black hair in a desired color because it can be easily colored and shampooed off. Such a temporary hair colorant is basically a mixture of a pigment and a setting agent component such as a resin component or an oil component for coating the pigment on the hair in a solvent.

However, hair mascaras require specific compounding ingredients other than those mentioned above due to their particular use form. That is, the hair mascara is, for example, as shown in FIG.
As shown in (b), it is housed in a hair mascara container 3 having a screw lid 2 with a brush 1, and when not in use, the hair mascara container 3 is sealed by the screw lid 2 and the brush 1 is a hair mascara liquid. It is immersed in. When using the hair mascara, the screw lid 2 is removed from the hair mascara container 3, the brush 1 is pulled out from the hair mascara container 3, and the hair mascara impregnated in the brush 1 is applied to a predetermined portion of the hair.

In the hair mascaras used as described above, there is a demand to complete the coloring of the hair easily and quickly. Therefore, in order to quickly dry the hair mascara applied to the hair, it is usually used. A highly volatile water-ethanol mixture is used as a solvent for hair mascara. On the other hand, since the brush is taken out of the hair mascara container while being impregnated with such volatile hair mascara, the hair mascara may be scattered from the brush at that time and may contaminate the user's skin or clothes. . In particular, as shown in FIGS. 1A and 1B, when the hair mascara container 3 is provided with a throttle valve 4 for squeezing the excessive hair mascara impregnated in the brush 1 at the time of extraction, Since the elastic bristles of the brush 1 that have passed through the throttle valve 4 repel, the scattering of hair mascara becomes more remarkable. In order to prevent such scattering of hair mascara, in order to achieve both volatility assurance and scattering prevention of hair mascara, for example, a preferable mixing ratio of a water-ethanol mixed solution, blending of a thickener, and the like have been studied. .

[0005]

However, it is difficult to achieve both volatility assurance and hair scattering prevention of hair mascara simply by adjusting the mixing ratio of water and ethanol in the water-ethanol mixture. In addition, with conventional conventional thickeners, if a large amount of thickener is added, the scattering of hair mascara can be prevented, but the volatility is significantly sacrificed. If the amount of thickener is reduced, hair mascara can be reduced. Could not be effectively prevented.

In addition to the above problems, good pigment dispersibility is naturally required for hair mascaras belonging to the category of temporary hair coloring agents in order to prevent changes and variations in color tone. Shows good covering power and texture (touch) to hair, excellent abrasion resistance (does not transfer color by rubbing against hair) and water resistance (abrasiveness when wet) Is also required. These points are considered to be problems mainly related to selection of a set agent, but conventional hair mascaras do not always show sufficient performance.

Therefore, the present invention provides a hair mascara which does not cause scattering during use while maintaining excellent volatility, and further has good pigment dispersibility, covering power, texture, abrasion resistance and water resistance. It is a problem to be solved to provide a hair mascara showing.

A hair mascara containing at least 0.1 to 15% by weight of amino-modified polyether-modified silicone as the setting agent component according to any of the first to fourth inventions.

(Operation and Effect of Fifth Invention) When hair-mascara is blended with 0.1 to 15% by weight of amino-modified polyether-modified silicone, the pigment is dispersed satisfactorily and stably.
Moreover, a hair mascara having good performance in which the covering power, texture, abrasion resistance and water resistance are well balanced is obtained.

Japanese Patent Laid-Open No. 2000-302837 discloses that
There is a description that Silsoft (trade name) manufactured by Witco Co., which is a kind of amino-modified polyether-modified silicone, was added to a cosmetic composition or a pharmaceutical composition. However, there is no disclosure in the same publication of the fact that Silsoft is blended with a pigment in a hair coloring agent or hair mascara, and therefore the effect of Silsoft blending on the performance of the hair coloring agent or hair mascara is naturally not evaluated. The effect has not been suggested.
