Description

TECHNICAL FIELD The present invention relates to a liquid lip cosmetic.

Lip cosmetics such as lipsticks are required to have a close-fitting feeling when they are applied to the lips to give a color, and to provide a uniform finish without discoloration.
For example, in Patent Document 1, a paste-like material obtained from a silicone elastomer and an oily component that is liquid at room temperature, a plate-like powder, and a lip base material containing an oily component have the effect of hiding fine wrinkles. It is described that it improves the uniformity of application of lipstick or the like, the longevity of makeup, and the like.

Japanese Unexamined Patent Application Publication No. 2003-2814

However, since the base material for lips of Patent Document 1 is used as a base material before applying lipstick, it is necessary to further apply a lip cosmetic material containing a coloring agent for color development. In order to save such time and effort, there has been a demand for a lip cosmetic that contains a coloring agent to give a uniform finish without color distortion. In addition, although the base material for lips of Patent Document 1 has a feeling of close contact, it also has problems in terms of feeling of use, such as stickiness.

The inventor of the present invention obtained a feeling of close contact with the paste oil and the plate-like powder, and furthermore, by using a combination of the spherical powder, it is possible to obtain a feeling of close contact, lightness at the time of application, and a soft touch to the lips. It was found that a liquid lip cosmetic that allows easy drawing of the contour can be obtained.

The present invention provides the following components (A), (B), (C), (D) and (E)
(A) 5 to 50% by mass of paste oil having a melting point of 30° C. or more and less than 61° C.,
(B) an oil component that is liquid at 25°C;
(C) Plate-like powder excluding component (E),
(D) spherical powder excluding component (E),
(E) A liquid lip cosmetic containing one or more selected from color pigments and pearl pigments and having a total content of components (C) and (D) of 10 to 60% by mass.

The liquid lip cosmetic of the present invention has a close contact feeling, is light when applied, has a soft touch, makes it easy to draw the outline of the lips, has a high moist feeling, and makes vertical wrinkles of the lips inconspicuous. and they are long-lasting.

Component (A) used in the present invention is a paste oil having a melting point of 30°C or higher and lower than 61°C.
In the present invention, the melting point is measured by Method 3 of the Standards for Cosmetic Ingredients General Test Methods. That is, the sample is gradually heated to 90 to 92° C. with stirring to melt, the heating is stopped, and the sample is allowed to cool to a temperature 8 to 10° C. higher than the melting point. 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.
