Description

  The present invention relates to an oily liquid eyeliner characterized by blending an organically modified synthetic clay mineral and a wax having a melting point of 60 to 100 ° C., and more specifically, has a light and smooth feeling during use, The present invention relates to an oily liquid eyeliner having good stability.

Oil-based liquid eyeliner has a cosmetic effect that makes the eyes look larger and makes the eyes clearer when applied to the eyes. Solid oils such as waxes, waxes, oil-soluble resins, and coloring pigments In addition, it is composed of powders such as luster pigments, extender powders, and film forming agents, and these are being studied for blending in order to produce a feeling of use as cosmetics and functionality. Further, oil gelling agents such as dextrin fatty acid esters and silicic anhydride have been used in order to impart thixotropy in consideration of both the usability and functionality as an eyeliner. (For example, refer to Patent Documents 1, 2, and 3) Further, in order to impart smoothness, a method of blending a spherical powder using a characteristic that a sphere rolls on a basket has been made. (For example, refer to Patent Document 4) In oily cosmetics such as lipstick, a technique for improving the temporal stability by imparting structural properties to the oil phase using an organically modified clay mineral is disclosed. (For example, see Patent Documents 5 and 6)

  In the techniques described in Patent Documents 1, 2, and 3, it is necessary to highly blend a wax having a melting point of 60 to 100 ° C. in order to ensure stability over time, and a uniform decorative film cannot be produced, or deformation of the applicator In some cases, it may cause deterioration of usability. In the technique of Patent Document 4, although a feeling of use with a light spread is obtained, the smoothness of the decorative film formed on the heel tends to be lost, and there is a tendency to have a matte finish with no gloss. In some cases, the powder enters the wrinkles and the cosmetic film lacks uniformity. In the techniques of Patent Documents 5 and 6, since gel contraction is large, there is a problem that the drainage cannot be suppressed, and it is possible to produce a smooth feeling during use, but satisfactory in terms of stability over time. I couldn't get anything.

  For this reason, it has been desired to develop an oily liquid eyeliner that is light and smooth when applied and has good temporal stability.

  Under such circumstances, the present inventor has diligently studied to solve the above-mentioned problems, and as a result, in the oily liquid eyeliner, a combination of an organically modified synthetic clay mineral and a wax having a melting point of 60 to 100 ° C. It was found that an oily liquid eyeliner having a smooth use feeling and good temporal stability was obtained, and the present invention was completed.

That is, the present invention provides components (a) to (b);
(A) Synthetic organically modified clay mineral (b) An oily liquid eyeliner containing a wax having a melting point of 60 to 100 ° C. is provided. Further, the oily liquid eyeliner and further the B-type rotational viscometer that the compounding amount of the component (a) is 0.1 to 5% by mass and the compounding amount of the component (b) is 0.01 to 10% by mass. In the measurement by (Rotor No. 4), the present invention relates to an oily liquid eyeliner having a viscosity at 25 ° C. of 20 to 800 Pa.s at 0.3 to 3 rpm and 5 to 60 Pa.s at 12 to 30 rpm.

  The present invention provides an oily liquid eyeliner excellent in durability of cosmetic effect and stability over time, such as forming a uniform cosmetic film on the heel and making the eyes stand out.
