Description

Technology Field

[0001] The present invention relates to a cosmetic composition containing a self-emulsifying film former, and more specifically, to a cosmetic composition that forms a film with breathability and water-repellent properties to enhance durability, and forms a film with elasticity and skin-like stretchability to provide a natural skin finish and a comfortable user experience without cracking when the product is applied to the lips or areas with frequent movement.

[0002] In addition, the present invention relates to a cosmetic composition that helps improve dispersion stability at the interface, enhances moisture retention and provides a glossy finish even after the film is completely formed and dried, and helps prevent the adhesion of fine dust. Background Technology

[0003] Lip makeup is more prone to smudging than other point makeup due to the frequent movement of the lips. Furthermore, unlike general skin, the lips have a very thin stratum corneum and lack sebaceous glands, so moisture evaporates quickly, causing them to dry out easily and develop dead skin cells. Consequently, lip makeup products are being released that offer long-lasting effects while providing moisturization and soothing benefits.

[0004] However, long-lasting matte products often contain high levels of powder or volatile oils and resins, which can easily dry out the lips and accentuate dead skin cells; consequently, users frequently use separate products for dryness relief and exfoliation. Meanwhile, while glossy products keep lips hydrated, their staying power is relatively lower. Therefore, research is being conducted to develop products that are highly moisturizing, glossy, and offer improved longevity.

[0005] Against this backdrop, the inventors confirmed that using a film former that forms a self-emulsifying structure not only improves the user experience but also enhances durability. Furthermore, by confirming moisturizing power, gloss retention efficacy, and fine dust adhesion prevention efficacy, the present invention was completed. Prior art literature

[0035] Figure 1 is the result of confirming the makeup longevity of a cosmetic composition according to the present invention. Figure 2 is the result of confirming the moisturizing efficacy through the evaluation of transepidermal water loss (TEWL) of the cosmetic composition according to the present invention. Figure 3 is the result of confirming the efficacy of improving glossiness through an evaluation of glossiness (gloss) improvement of the cosmetic composition according to the present invention. Figure 4 is the result of confirming the efficacy of preventing fine dust adhesion through an evaluation of the prevention of fine dust adsorption of the cosmetic composition according to the present invention. Specific details for implementing the invention

[0036] Hereinafter, the cosmetic composition according to the present invention will be described in detail with reference to test examples and embodiments, but the present invention is not limited to these test examples and embodiments. These embodiments are provided to further explain the present invention in detail to those skilled in the art to which the present invention belongs.

[0038] In the case of conventional emulsion products using emulsifiers, that is, acrylic emulsions containing acrylate copolymer components, the interface of the emulsifier is further maintained at the interface between the polymer and water after water dispersion by forced emulsification, whereas in the case of a formulation containing a self-emulsifying film former containing PPG-17 / IPDI / DMPA copolymer components as a film-forming agent, hydrophilic and hydrophobic parts exist together within the polymer structure without using other emulsifiers, thus excluding the problems that may arise from the emulsifier.

[0039] Furthermore, when using conventional emulsifiers, the emulsifier forms an interface between oil and water, resulting in the separation of hydrophobic and hydrophilic regions. However, when a self-emulsifying film former is included, both hydrophobic and hydrophilic properties are present within a single molecule; thus, while the hydrophilic region forms the interface at the point of contact with water, the internal hydrophobic region allows hydrophobic additives to penetrate into the particle, thereby improving dispersion stability.

[0040] In addition, while conventional emulsion products using emulsifiers destroy the skin's protective barrier due to the emulsifier, causing the skin to dry out, the formulation containing the self-emulsifying film former in the present invention has the characteristic that, after drying, the additives that have penetrated into the particles become surrounded by a polymer material, allowing them to maintain their function for a longer period and behave together with the particles forming a layered structure.

[0041] In addition, regarding the film, conventional emulsion products using emulsifiers have fluidity as a liquid film, which can penetrate pores, and the oil that protects the skin is washed away by the emulsifier, resulting in the generation of even more oil. In contrast, the self-emulsifying film former of the present invention has breathability and elasticity similar to skin, possessing breathability and water resistance. Furthermore, since it has elasticity but lacks mobility, it does not penetrate pores and can suppress oil secreted from the body, thereby improving durability.

[0042] The PPG-17 / IPDI / DMPA copolymer component contained in the self-emulsifying film former of the present invention is a copolymer of PPG-17, isophorone, diisocyanate, and dimethylolpropionic acid monomer, and is used as a film-forming agent.

[0048] The method for preparing the composition of the lip cosmetic of Comparative Examples 1 to 5 is as follows.

[0049] An emulsion system was prepared by heating and dissolving octyldodecanol, diisostearyl malate, sorbitan sesquioleate, sorbitan oliveate, red iron oxide, and Red 202 at 75°C to 80°C. Ammonium acryloyldimethyltaurate / VP copolymer, butylene glycol, pentylene glycol, hyaluronic acid, Yellow 5, Red 227, and Red 104 (1) were dispersed in purified water, and the emulsion system dissolved in the aqueous phase heated to 70°C to 75°C was added, and then emulsified for 5 minutes at 3,500 to 5,000 rpm using a homomixer.

[0052] <Experimental Example>

[0053] Experimental Example 1. Formulation Stability

[0054] To evaluate the stability of the formulations, the stability of the compositions of Examples 1 to 7 and Comparative Examples 1 to 5 under different temperature conditions was confirmed. Each composition was stored for one month under conditions of room temperature, 25°C, low temperature (4°C), high temperature (50°C), and cycle (-5°C to 44°C / 24hr), after which the separation of the formulations was observed. Viscosity (cPs) was measured using a Brookfield RVT under conditions of Spindle RV-4, 12 rpm, and 25°C. The evaluation results are shown in Table 2.

[0057] As shown in Table 2, although there were differences in viscosity depending on the content when containing the same film former, it was confirmed that Examples 1 to 7 containing self-emulsifying film formers showed improved formulation stability relative to the applied content compared to Comparative Examples 1 to 5 containing general film formers.

[0058] In Examples 4 to 7 containing self-emulsifying film formers, the aging viscosity was lower than that of Examples 1 to 3, but stability was shown in high-temperature stability due to the self-emulsifying power. However, in the case of Example 7, when observing high-temperature stability, a gradual clumping phenomenon was observed within the formulation over time.

[0059] In the case of Comparative Examples 1 to 5, there was a significant difference in viscosity depending on the content, and as a result, Comparative Examples 4 to 5 showed instability at room temperature and high temperature stability.

[0061] Experimental Example 2. Evaluation of User Sensibility of Cosmetic Composition

[0062] The compositions of Examples 1 to 7 and Comparative Examples 1 to 5 were used by 10 applicants in their 20s and 30s, and the results were compared and evaluated. Adhesion and spreadability were sensorially evaluated, with evaluation criteria set to 1 (very poor), 3 (average), and 5 (very good), and the results are shown in Table 3.

[0064] As shown in Table 3, Examples 1 to 7 and Comparative Examples 1 to 5 showed a tendency for adhesion and spreadability to increase as the content of the self-emulsifying film former increased. However, Example 1 showed minimal improvement in adhesion and spreadability, and Example 7 had poor spreadability due to clumping within the formulation.

[0065] It was confirmed that the compositions of Examples 1 to 7, which contain a film former that forms self-emulsifying power when containing the same amount of film former, showed superior adhesion and spreadability compared to Comparative Examples 1 to 5, thereby improving the user experience.

[0067] Experimental Example 3. Evaluation of Makeup Longevity Improvement

During the preparation phase, the test area was kept clean and dry to ensure uniform measurement conditions for all subjects, and the procedure was performed after the skin stabilized for at least 30 minutes in an environment maintaining constant temperature and humidity (22±2℃RH 40–60%). During the measurement phase, 2 mg / cm² of the test product was applied to a selected test area (4 cm x 3 cm) on the forearm using a micropipette. 2 It was applied in an amount of [amount]. Using a Spectrophotometer CM-700d / 600d (Konica Minolta, Japan), the L (Lightness), a (red-green chromaticity), and b (yellow-blue chromaticity) values ​​of the skin surface were measured before, after, and 3 hours after product application, and the degree of makeup longevity evaluation was calculated using the method of Equation 1 below. The results are shown in Figure 1 and Table 4.

[0076] Experimental Example 4. Evaluation of Transepidermal Water Loss (TEWL)

[0077] During the preparation phase, the test site was kept clean and dry to ensure uniform measurement conditions for all subjects, and the procedure was performed after the skin was stabilized for at least 30 minutes in an environment maintaining constant temperature and humidity (22±2℃RH 40–60%). In the measurement phase, the test product was applied to a selected test site (5cm x 4cm) on the forearm using a micropipette at a dose of 2 mg / cm². 2 It was applied in an amount of [amount]. Measurements were taken a total of three times—before use and 3 hours later—and the average value was calculated using the three values. Transepidermal water loss was measured using a Tewameter®™ 300 instrument, and the results are shown in Figure 2 and Table 5.

Subjects were selected from adults aged 26 to 39 who met the selection criteria and did not fall under any exclusion criteria. For the test method, the test site was kept clean and dry during the preparation phase to ensure uniform measurement conditions for all subjects. The test was conducted after allowing the skin to stabilize for at least 30 minutes in an environment maintaining constant temperature and humidity (22±2℃, RH 40–60%). During the measurement phase, the test product was applied to a selected test site (2cm x 2cm) on the forearm using a micropipette at a concentration of 2 mg / cm². 2It was applied in an amount of [amount]. After application, the sample was left in a constant temperature and humidity room for 15 minutes, then exposed to fine dust, and the fine dust-like substance remaining on the test area was analyzed. Carbon black (MITSUBISHI MA220, JAPAN) was used as the fine dust-like substance.
