Description

Lip cosmetic composition

This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0126215 filed on September 30, 2016, and includes all contents described in the literature of that Korean patent application as part of this specification.

The present invention relates to a lip cosmetic composition, and more particularly, the present invention relates to a lip cosmetic composition having excellent shape retention and excellent applicability and applicability, and a lip cosmetic composition comprising the same.

Lip cosmetics such as lipsticks, lip gloss, lip balms, and lip pencils are used for the purpose of protecting the lips while giving them color to make them look beautiful.

Among them, the lipstick, which is a cosmetic for lips in the form of a solid stick, provides a soft application and has a form that is easy to apply to the entire lips. However, since the lipstick alone has a limitation in expressing a clear mouth, it is troublesome to draw a lip line separately using a lip liner or to use a makeup tool such as a brush for delicate lip makeup.

On the other hand, the lip liner is generally made of a thin pencil type for delicate expression of the contour of the lips. Therefore, it takes a lot of time when used in a large area, because it shows a relatively stiff feeling of use is not suitable for applying over the entire area of the lips.

To overcome this problem, products such as lip pencils in the middle of lipstick and lip liner are sold. However, since the lip pencil is not sufficiently high in hardness, the tip becomes worn out as it is used. Therefore, in order to restore the function as a lip liner, it is inconvenient to reconstruct the shape of the tip using a sharpener.

Therefore, the application of excellent lipability and ease of application, expression of delicate makeup is possible and the development of a new lip cosmetic composition with less deformation of the form according to the use is required.

Production Example  2: manufacture of lipstick

The oil-based cosmetic composition prepared in Preparation Example 1 was dissolved by heating to 95 ° C. or more, and then poured into a lipstick-shaped molding mold having a diameter of 4 mm, followed by cooling (-20 ° C. and 10 minutes) to bind the contents to the container. The contents bound to the container were stored for at least 12 hours in a thermostat at 30 ℃.

Experimental Example  1: lipstick hardness measurement

The hardness was measured in the following manner with respect to the lipstick prepared in the same manner as in Preparation Example 2, except that the lipstick-shaped molding mold having a diameter of 11 mm was used.

The lipstick stored in the thermostat at 30 ° C. was taken out, immediately placed in a container, the contents were taken out, and a piano string (0.2 mm thick) was placed in the center of the contents. While moving the piano string at a speed of 20 mm / min and cutting the contents about 20 mm, the force received at 10 to 19.5 mm of the moving distance was measured (Rheometer CR-300, SUN Scientific Co., LTD) and the average value The hardness of the lipstick was obtained by obtaining.

As a result, in Example 1 and Comparative Example 2, 190 gf, Comparative Example 1 was measured to 150 gf, it was confirmed that all show a high hardness of 100 gf or more.

Experimental Example  2: sensory evaluation

Ten expert panel evaluation group was to evaluate the degree of color development, gentle application and lip stickiness after application of the lipstick prepared in Preparation Example 2. The evaluation was made out of 5 points for each item, and the stronger the attribute was, the higher the number was indicated. Table 2 shows the result (average value).

	Example 1	Comparative Example 1	Comparative Example 2
Smooth application	3.3	2.2	1.4
Lip stickiness after application	2.4	3.4	3.0
Color development degree	4.1	4.0	3.3

Referring to Table 2, it can be seen that in Example 1, even though the hardness is high, the applicability is very smooth. However, Comparative Example 1 obtained a lower score than Example 1 in the application property even though the hardness was lower than that of Example 1, and in Comparative Example 2, in which the hardness was the same as that of Example 1, evaluation of the application was very poor. In addition, Example 1 showed less lip stickiness after application and excellent color development compared with Comparative Examples 1 and 2.

From the above results, it can be seen that when the high melting point wax is used in the lip cosmetic composition, the applicability is remarkably improved at the same hardness as compared with the case of the conventional wax, and the stickiness is less and the color development property can be improved.

Lip cosmetic composition of the present invention is excellent in durability and suitable for the manufacture of lipstick of the ultra-slim form of 6 mm or less, the deformation of the shape does not easily occur with use. Thus, the lipstick prepared from the lip cosmetic composition of the present invention may perform a role as a lipstick and a lip liner at the same time by narrowly forming a portion of the cross section.
