Description

Lip cosmetic composition with excellent gloss and color retention of the coating film

[0001] The present disclosure relates to a cosmetic composition for lips having excellent gloss and color durability of a coating film.

[0002] Cross-reference to related applications

[0003] This application claims priority to Republic of Korea Patent Application No. 10-2024-0098427, filed July 25, 2024, the entire contents of which are incorporated herein by reference.

[0004] Various methods have been attempted to increase the gloss of the coating in glossy or glow-in-the-dark formulations. Typically, the gloss effect is achieved by maximizing the content of high-gloss oils and high-viscosity pastes while minimizing the powder content.

[0005] In addition, to ensure color persistence, a dye is used together with a pigment to achieve a lasting effect through a coloring effect, and this method can be considered the only color persistence in a glow formulation.

[0006] However, in the case of glow formulations that have gloss and shine as the main external effects of color makeup, powder pigments (colorants) are essential, but if they are contained in large quantities, there is a limit to the glossiness being reduced due to the absorption power of the powder, so pigments are contained in a minimum amount, and as a result, glow formulations generally have the disadvantage of low color development and durability.

[0059] [Test Example 1] Gloss measurement of coating film according to powder type

[0060] The gloss of the coating film of the lipstick compositions of Comparative Examples 1 and 2 and Examples 1 to 5 was measured using a gloss meter. Specifically, each composition was equally applied to LENETA and FORM 18A dedicated paper and measured using a device (mircro TRI Gloss, BYK). The results are shown in Table 2 below.

[0062] From the results in Table 2 above, it was confirmed that the gloss of the coating film of Comparative Example 2 including spherical powder was significantly lower than that of the case where no powder was included (Comparative Example 1) or the case where plate-like powder was included (Examples 1 to 5). In addition, among the plate-like powders, it was confirmed that the gloss of Examples 2 to 4 including alumina and surface-coated mica was excellent at all angles. However, in order to compare the gloss levels observed with the naked eye when applied to actual skin, the compositions of Examples 2 to 4 were applied in equal amounts to the inner arm and then evaluated with the naked eye immediately afterward. According to Fig. 1 (Examples 2, 3, and 4 in order from the left), it was confirmed that the gloss of Example 2 was the best.

[0063]

[0064] [Manufacturing Example 2] Manufacturing of a cosmetic composition for lips

[0065] Lipstick compositions were manufactured using the same method as in Manufacturing Example 1, with the compositions shown in Table 3 below, and the results of hardness measurement (device model name: CR-300, measurement conditions: Mode 20 Distance; Load Cell (maximum) 2 kgf; adapter number No. 8, sample conditions: cylindrical stick) of each composition are shown together in Table 3.

[0068] [Test Example 2] Visual evaluation of gloss and color development of coating film according to alumina content

[0069] The gloss and color development of the coating films of the lipstick compositions of Comparative Example 3 and Examples 6 to 9 were visually evaluated. Specifically, each composition was applied in equal amounts to the inner arm and immediately evaluated visually. The results are shown in Figure 2 below (from left to right, Comparative Example 3, Example 6, Example 7, Example 8, and Example 9).

[0070] From the results of FIG. 2, it was confirmed that the lipstick compositions of Comparative Example 3, which did not contain alumina, and Example 6, which contained 0.5 wt% of alumina, had significantly lower coloring power and a very low gloss effect compared to the compositions of Examples 7 to 9. In particular, the lipstick composition of Example 6, which contained 0.5 wt% of alumina, had the lowest hardness value, and thus had significantly lower coloring power despite excellent application and spreadability. In contrast, the compositions of Examples 8 and 9 had high hardness values, which were expected to be disadvantageous in terms of application and spreadability, but it was confirmed that the coloring power and gloss effect of the coating film were very excellent. From this, it was confirmed that the coloring power and gloss effect of the coating film of the lipstick composition did not depend on the hardness of the composition.

[0071]

[0072] [Test Example 3] Scanning electron microscope (SEM) images of coating films with different alumina contents.

[0073] The coating films of the lipstick compositions of Comparative Example 3, Examples 6 and 7 were photographed using a scanning electron microscope (SEM-EDS system, ZEISS Gemini SEM300, acceleration voltage 2.0 to 10.0 kV, Working Distance (WD) 6 to 7 mm), and the 1000x magnification images are shown in FIGS. 3a to 3c, respectively.

[0074] As shown in FIGS. 3a to 3c, compared to Comparative Example 3 (FIG. 3a) and Example 6 (FIG. 3b) which do not contain alumina or contain 0.5 wt% of alumina, it was found that the coating film of the lipstick composition of Example 7 (FIG. 3c) has multiple layers of alumina to form a uniform base, thereby providing a much superior light reflection effect.

[0075]

[0076] [Test Example 4] Evaluation of gloss, color development, and spreadability of coating films according to alumina content

[0077] The gloss and color development of the coating film of the lipstick compositions of Comparative Example 3 and Examples 6 to 9, as well as the spreadability, were evaluated. Specifically, the gloss and color development of the coating film were relatively evaluated through visual observation after applying the same amount of each lipstick composition to the inner arm, and the spreadability was evaluated by having 10 women aged 25 to 45 apply each lipstick composition to their lips. The smooth application feeling was evaluated on a 5-point scale, and the average value was expressed. The results are shown in Table 4 below. (5 points: very good, 4 points: good, 3 points: average, 2 points: below average, 1 point: poor, 0 points: poor)

[0078] Comparative Example 3 Example 6789 Gloss and color development 1.2 1.8 3.5 4.2 4.8 Smooth application 4.6 4.2 3.8 3.2 1.4

[0079] From the results in Table 4 above, it was confirmed that Comparative Examples 3 and 6, which did not contain alumina or contained 0.5 wt% alumina, had excellent spreadability, but the gloss and color development of the coating film were significantly reduced. In addition, Example 9, which contained 10 wt% alumina, had the best gloss and color development, but it was confirmed that a negative feeling occurred when applied to the lips and the spreadability was significantly reduced.

[0080]

[0081] [Manufacturing Example 3] Manufacturing of a cosmetic composition for lips

[0082] A lipstick composition of Comparative Example 4 was prepared using the same method as in Manufacturing Example 1, but without plate-shaped powder (alumina) and alkyl glyceryl ether modified silicone (glyceryl undecyl dimethicone) as in Table 5 below.

[0086] The gloss, color development, and color staying power of the lipstick compositions of Comparative Examples 3 and 4 and Example 7 were evaluated. Specifically, equal amounts of each composition were applied to the inner arm, and after 30 minutes, the area was wiped off three times with a tissue, and the remaining color level was checked and evaluated. The results are shown in Figures 4a and 4b (from left to right, Comparative Example 4, Comparative Example 3, and Example 7).

[0087] From the results of FIGS. 4a and 4b, it was confirmed that the lipstick composition of Comparative Example 4, which did not contain either the platelet powder (alumina) or the alkyl glyceryl ether-modified silicone (glyceryl undecyl dimethicone), had poor gloss and color development of the coating film, and very low color staying power, and that the lipstick composition of Comparative Example 3, which contained only glyceryl undecyl dimethicone and did not contain alumina, had excellent color staying power, but poor gloss effect and color development of the coating film. On the other hand, it was confirmed that Example 7, which contained both alumina and glyceryl undecyl dimethicone, had excellent color development and gloss effect of the coating film, and very good color staying power.

[0093] [Test Example 6] Evaluation of dispersibility and spreadability according to the content of phenyl-modified silicone

[0094] The dispersibility and spreadability of the lipstick compositions of Examples 10 to 12 and Comparative Examples 5 to 7 were evaluated, and the spreadability evaluation method was the same as that of Test Example 4. The results are shown in Table 7 below. (5 points: very good, 4 points: good, 3 points: average, 2 points: below average, 1 point: poor, 0 points: poor)

[0095] Comparative Example 101112567 Dispersing Power 155423 Spreadability 2.84.63.13.13.33.3

[0096] From the results in Table 7 above, it was confirmed that as the content of phenyl-modified silicone increased, the pigment dispersing power increased. However, when the content was 10 wt% and 50 wt%, it was confirmed that there was a problem that the pigment did not spread smoothly or was applied too slippery when applied to the lips, resulting in poor adhesion. In the case of Comparative Examples 5 and 7, which contain oil rather than phenyl-modified silicone, the hardness was very low as shown in Table 6, making them unsuitable for lipstick formulations. In addition, it was predicted that when the wax content was increased to increase the hardness to a level suitable for lipstick formulations, the gloss effect of the coating film would be reduced due to the high wax content. In addition, in the case of Comparative Examples 6 and 7, it was confirmed that the dispersing power was average or below average, which was poor compared to the examples.
