Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a liquid makeup for brush pen type cosmetics. Charge The present invention relates to a filled brush pen cosmetic. More specifically, a liquid makeup for brush pen type cosmetics using black iron oxide as a black pigment. Charge The present invention relates to a filled brush pen cosmetic.
[0002]
[Prior art]
The brush pen type cosmetic is a brush pen type cosmetic, which contains a liquid cosmetic, guides the liquid cosmetic to a brush tip, and performs makeup with the brush. Brush pen-type cosmetics are usually filled with a low-viscosity liquid cosmetic in a container called a refill or cartridge, etc., and the liquid-type cosmetics in the applicator are installed in a brush-pen type applicator. It is to be introduced to the brush tip. Further, many applicators have a function of assisting the introduction of the liquid cosmetic material to the brush tip by knocking the opposite side (rear end) of the brush tip.
[0003]
In these brush pen-type cosmetics, if the viscosity of the liquid cosmetic is high, the liquid does not flow to the brush, the liquid does not discharge from the brush tip, or clogs. If discharged, there is a risk of dripping or jetting at the time of discharge, and it is difficult to adjust the amount of liquid contained in the brush tip, and a low viscosity of 100 mPa · s or less is not possible because a certain line is not applied and the usability is poor. It is required to be. If the liquid cosmetic composition has a low viscosity, the liquid cosmetic composition used in a conventional brush pen-type cosmetic composition is dispersible as a black pigment because pigment precipitation, aggregation, etc. occur in the liquid cosmetic composition and clogging occurs. There are some that use carbon black and tar pigments, but these may be regarded as problems in terms of safety.
[0004]
On the other hand, black iron oxide as a black pigment has no problem in safety, but is inferior in dispersibility compared to carbon black and tar dyes, and also applies an external force to the precipitated and separated pigment so that it is uniformly dispersed again. Redispersibility is also poor. Therefore, when blended with liquid cosmetics for brush pen type cosmetics, even if the act of shaking the brush pen type cosmetics multiple times before use, the brush will clog over time and the liquid cosmetic will not be discharged Therefore, it was difficult to mix.
[0005]
Examples of techniques for suppressing clogging over time due to blending of black iron oxide include, for example, a technique using a specific polymer dispersant and a specific nonionic active agent in combination (for example, see Patent Document 1), and black iron oxide. There is a technique (for example, see Patent Document 2) using a specific micellar agent after surface treatment with a fatty acid and a salt thereof. However, none of these were satisfactory because the effects were not sufficient or the blending of the polymer emulsion for improving the makeup lasting time was difficult and the makeup lasting time was insufficient.
