[Industrial application fields]
The present invention relates to an oily mascara, and more specifically, is excellent in water resistance, sebum resistance, and oil resistance (oil contained in cosmetics such as foundations, creams, and makeup bases), and has high strength and adhesion of the film, curling power and The present invention relates to an oily mascara that has excellent usability (smoothness) and can be removed with a normal cleansing material.
[0002]
[Prior art]
Mascara is required to have effects such as long-lasting eyelashes and a sense of volume, makeup retention (water resistance, oil resistance, sebum resistance), curling power, and the like. Moreover, the ease of dropping with a normal cleansing fee is required.
[0003]
Conventionally known emulsified mascara is generally composed of solid, semi-solid, liquid oil to water. Volumetric feeling and curling power are being studied by a method of highly blending solid components such as wax and powder and a method of highly blending polymers such as water-based synthetic resin polymer emulsions to increase adhesion. However, because of the above effects, the system becomes very viscous and difficult to apply, resulting in a disadvantage that the finish is poor. Further, since the polymer emulsion itself does not have water resistance, a mascara that is satisfactory in terms of water resistance is not necessarily obtained.
[0004]
In oily mascara, solid, semi-solid, liquid oil to volatile branched hydrocarbons are the main components. Since there is no water and the eyelashes are not softened, it is preferable in terms of curling force. However, the oil resistance and sebum resistance are poor, and in particular, there is a drawback that mascara bleeds into oils such as sebum and other cosmetics and easily stains the periphery of the eyes. Moreover, it cannot be said that the drying property is excellent.
[0005]
In recent years, mascara using an organic silicone resin as a coating agent has been developed (Japanese Patent Publication No. 5-74562), and is useful in terms of water resistance, oil resistance, and sebum resistance. However, when the organosilicone resin is blended in a high amount, it is difficult to remove the organic silicone resin, so that there is a drawback that it takes a lot of time for washing. Also, a mascara that is satisfactory in terms of drying properties and curling power cannot be obtained.
[0006]
[Problems to be solved by the invention]
Accordingly, the problem to be solved by the present invention is to provide a mascara that overcomes the drawbacks described in the prior art. (1) Excellent in water resistance, sebum resistance, and oil resistance (oil contained in cosmetics such as foundations, creams, makeup bases, etc.), (2) High strength and adhesion of the film, curl strength and use (3) To provide a mascara that simultaneously satisfies various conditions that it can be removed with a normal cleansing charge.
[0007]
