Description

LIP COSMETIC COMPOSTION [0002]

The present invention relates to a lip cosmetic composition, and more particularly, to a lip cosmetic composition excellent in shape retention ability and excellent in spreadability and spreadability, and a lip cosmetic composition containing the same.

Lip cosmetics, such as lipsticks, lip gloss, lip balm, and lip pencil, are used for the purpose of protecting the lips while at the same time giving the lips a beautiful look.

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

On the other hand, lip liner is generally made of a thin pencil type for delicate representation of lip contour. Therefore, it is time-consuming to use in a large area, and it is not suitable for application to the entire area of the lips since it shows relatively stiff feeling.

To overcome this problem, products such as a lip pencil in the form of an intermediate lipstick and lip liner are being sold. However, since the lip pencil is not sufficiently high in hardness, the end portion of the lip pencil 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 end portion using a sharpener.

Therefore, there is a need to develop a new lip cosmetic composition which is excellent in spreadability and ease of application, can express delicate cosmetics, and is less deformed depending on use.

When such a small diameter and a steep cutting angle are satisfied, a sharp lip edge can be expressed in a delicate manner, and a wide bevel can be applied to a wide area at one time. There is no need for a lip liner, and quick and easy lips makeup is possible, which can shorten the makeup time.

Particularly, since the lip cosmetic composition of the present invention has a high hardness of 100 to 300 gf, the cross-sectional shape as described above can be kept constant even after continuous use. Therefore, the ease of use is increased because the end portion of the lip pencil is not required to be rebuilt like a pencil.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Changes and modifications may fall within the scope of the appended claims.

Production Example 2: Production of lipstick

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

Experimental Example 1: Measurement of lipstick hardness

The hardness of the lipstick prepared in the same manner as in Production Example 2 was measured in the following manner, except that the lipstick-shaped forming die having a diameter of 11 mm was used.

The lipstick stored in a thermostatic chamber at 30 ° C was taken out immediately and the container was immediately set up, the contents were taken out, and a piano string (thickness 0.2 mm) was placed in the center of the contents. The piano cord was moved at a speed of 20 mm / min and the contents were cut about 20 mm. The force was measured at 10 to 19.5 mm of the moving distance (Rheometer CR-300, SUN Scientific Co., LTD) And the hardness of the lipstick was determined.

As a result, it was confirmed that 190 gf of Example 1 and Comparative Example 2 were measured and 150 gf of Comparative Example 1, indicating that all of them had a high hardness of 100 gf or more.

Experimental Example 2: Sensory evaluation

10 panelists of professional panel evaluators evaluated the degree of color development, the degree of softening of the lipstick prepared in Preparation Example 2, and the degree of lip sticking after application. For each item, the evaluation was out of 5 points, and the higher the number of items, the higher the number. The results (average value) are shown in Table 2 below.

Example 1 Comparative Example 1 Comparative Example 2 Soft wearing 3.3 2.2 1.4 Lip sticky after application 2.4 3.4 3.0 Degree of color development 4.1 4.0 3.3

Referring to Table 2, it can be seen that Example 1 shows very smooth even when hardness is high. However, Comparative Example 1 showed lower hardness than Example 1 in terms of hardness even though it showed lower hardness than Example 1, and Comparative Example 2, which has the same hardness as Example 1, was evaluated to have poor wettability. In addition, Example 1 showed less lips tackiness after application than Comparative Examples 1 and 2, and showed excellent coloring power.

From the above results, it can be seen that when the high-melting-point wax is used in the lip cosmetic composition, the spreadability is remarkably improved at the same hardness as compared with the case of using the conventional wax, the stickiness is small and the coloring power property is improved.

The lip cosmetic composition of the present invention is excellent in durability and is suitable for manufacturing lipsticks of an ultra slim shape of 6 mm or less and does not easily deform the shape according to use. Accordingly, the lipstick made of the lip cosmetic composition of the present invention can simultaneously perform a role as lipstick and lip liner by narrowly forming a part of a cross section.
