Add the phases and stir further. Thereafter, the liquid temperature was further lowered to room temperature with cooling water to obtain a viscous eyelash cosmetic.

Example 2 A, B and C phases were uniformly mixed and stirred at room temperature to obtain a viscous eyelash cosmetic.

Example 3 In the same manner as in the comparative example, first, phase A was stirred and mixed, added and dissolved in phase B heated to 80 ° C. and uniformly stirred, and then cooled to 40 ° C. with cooling water. After cooling, add phase C and stir further. Thereafter, the liquid temperature was further lowered to room temperature with cooling water to obtain a viscous eyelash cosmetic.

Test Example 1 In order to examine the hair growth effect, gloss contributing effect and safety of the above-mentioned cosmetics on eyelashes, tests were carried out by the following methods. The test material and the control sample were applied to the upper and lower eyelashes after the application by brush from the root to the hair tip once a day for 30 consecutive days to 20 female subjects from 18 to 40 years old. After the test was completed, a questionnaire was conducted regarding the realization of the hair growth effect and gloss contribution effect of the eyelashes, and the presence or absence of irritation to the eye mucosa. Table 2 shows the results.
