Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD [0001] The present invention is excellent in the cosmetic effect and the persistence of clarifying the necessary eyes for cosmetics for eyelashes, the uniformity of the finished film, and the good usability and safety and stability. The present invention relates to makeup cosmetics in which the odor peculiar to resins is reduced.

[0002]

2. Description of the Related Art Conventionally, the cosmetic effect of clarifying the eyes in cosmetics for eyelashes is to increase the adhesion to the eyelashes by blending waxes, resins, film-forming agents, etc.
The eyelashes were made to stand out thickly or look long, and the eyelashes were curled up to make the eyes stand out. Further, by blending powder into these systems, stickiness of the coating film is prevented, and bundling of eyelashes is prevented, so that the eyes are more effectively highlighted.

[0003]

However, many conventional waxes, resins represented by rosin acid derivatives, and the like have high melting points and poor flexibility and adhesiveness at room temperature. There is a problem in that the adhesiveness to the eyelashes is poor, the effect of making the eyelashes look thick is insufficient, and the curl of the eyelashes tends to be linear due to the poor flexibility of the coating film. In addition, when blended to such an extent that a sufficient effect can be obtained, it leads to deterioration of usability such as poor elongation in the product and deterioration of usability such as uneven elongation. At the same time, the amount of powder blended to prevent stickiness increases, the makeup film becomes non-uniform, the makeup lasts poorly, and peeling over time is observed. Further, these resins have a peculiar odor, and the odor tends to intensify with the lapse of time, so that there is a drawback in that the odor is not preferable when a large amount is blended.

[0004]

Therefore, as a result of intensive studies to solve the above problems, the present inventors have found that the inclusion of a candelilla resin and a spherical powder improves usability,
The present invention has been completed by finding that a cosmetic for eyelashes can be obtained, which is excellent in the feeling of use, has the effect of clarifying the eyes, its durability, and the uniformity of the finished film. That is, the present invention relates to a cosmetic for eyelashes, which contains candelilla resin and spherical powder.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.

As a method for this fractional extraction, for example, ethanol is added to the candelilla wax and the candelilla wax is dissolved by heating on a water bath or the like. Next, this is cooled to room temperature to precipitate wax crystals, and this is filtered to separate crystals and filtrate. Since the resin component is dissolved in the filtrate,
A resin component can be obtained by distilling and recovering ethanol in the filtrate. Further, the softening point of the candelilla resin is preferably 35 to 55 ° C., for example, the INCI name (In
