Description

The present invention relates to a lip cosmetic.

Lip cosmetics such as lipsticks are required to have various finishes and effects.
For example, various studies have been made in order to obtain excellent luster, feeling of use, and the like. Patent Document 1 discloses that a lip cosmetic using a dextrin fatty acid ester, a wax having a specific melting point, and a semi-solid oil in a specific ratio maintains the luster of the finish and prevents vertical lines on the lips even after the passage of time. It is described that it suppresses the conspicuousness of chapped wrinkles and lips and gives a care effect.

The inventors of the present invention have found that when a lip cosmetic contains a large amount of an extender pigment, when it is spread and applied to the lips, it becomes uneven and uneven, resulting in a beautiful matte finish. I found a problem that there is no.

The present inventors have found that if an oil component containing an oil component with a specific melting point in a specific ratio and an oily gelling agent are used, even if a large amount of an extender pigment is contained, it will not become uneven during application and can be applied thinly and uniformly. It was found that a lip cosmetic that can be applied and has a beautiful matte finish can be obtained.

Next, after cooling the thermometer (the thermometer for the melting point of petrolatum specified in Japanese Industrial Standard B7410) to 5°C, remove the moisture with filter paper, insert half of the mercury ball into the sample, remove it immediately, and keep it vertical. Allow to cool, and when the adhering sample becomes turbid, immerse in water at a temperature of 16°C or less for 5 minutes. Next, insert the thermometer into the test tube and fix the thermometer with a cork so that the distance between the lower end of the thermometer and the bottom of the test tube is 15 mm. This test tube is placed in a 500 mL beaker containing water at about 16°C, and the bottom of the test tube is fixed at a distance of 15 mm from the bottom of the beaker. Heat in increments of 2°C. Then, the heating is continued so that the temperature rises by 1° C. per minute, and the temperature is measured when one drop of the sample leaves the thermometer. This test is performed 3 times, and when the difference in the measured values is less than 1°C, the average value is taken.
