Description

Makeup

This application claims the priority of Japanese Patent Application No. 2018-131071 filed on July 10, 2018, and incorporates it into this document.

The present invention relates to cosmetics, and in particular to cosmetics which are smooth even though they have matte matting results.

The texture of skin and lips coated with cosmetics is roughly divided into two that give gloss and matte matte feeling. Among them, the cosmetics that are liquid cosmetics and have a matte matte texture are mostly those with poor smoothness and wrinkles that become noticeable over time. In addition, the cosmetics with matte matte feeling are too hard to be made into tubes, and are not directly applied from the container, but are applied by using an applicator pre-installed in the container, or filled in the inner tray Or a container for a can (see, for example, Patent Document 1).

, Penetration depth: 3mm, Ascent speed: 20mm/min, Measuring temperature: 25°C).

Evaluation (2): Use feeling (smoothness, matte matte feeling, noticeability of longitudinal wrinkles, moist feeling)

Ten professional reviewers applied the sample to the lips, and evaluated the feeling of use (smoothness, matte matte feeling, longitudinal wrinkle visibility, moisturizing feeling) during application.

A: 9 or more people answered that the feeling of use was good (smoothness, matte matte feeling, longitudinal wrinkles are not obvious, and moist feeling).

B: Eight people answered that the feeling of use was good.

C: Seven people answered that the feeling of use was good.

D: Five or more and less than seven answered that the feeling of use was good.

E: 4 people answered that the feeling of use was good.

F: Less than 4 people answered that the feeling of use was good. When the above evaluation is E or more, it is set as a person with a good sense of use, and F is set as a person with a poor sense of use.

Evaluation (3): Stability

The samples were stored at a low temperature (5°C) and a high temperature (40°C) for 30 days, and compared with the standard products stored at normal temperature (25°C) to confirm the presence or absence of separation.

G: No separation

B: There is separation

The present inventors prepared the cosmetics (lip cosmetics) shown in Tables 1 and 2 below using a known method, filled them in a tubular container, and measured them using the evaluation method described above. The results are shown in Table 1 and Table 2.
