Problems solved by technology

However, since an oil with a high refractive index has a property that the feeling of use is somewhat heavy and thick, when a large amount of raw materials is applied to a dosage form, a thick cosmetic film is formed and a dull feeling of use is produced
In addition, in the case of high-refractive oil, it is vulnerable to sebum, etc., and the makeup film is easily broken, and the luster of the skin on which the formulation is applied decreases over time
In such high-refractive oil-based compositions, oil-phase polymers can be used to prevent makeup damage, but there are limitations in the application of oil-phase polymers due to the thickness of the makeup film, the feeling of use, or the effect of makeup, etc.

[0032] Preparation of Examples and Comparative Examples

[0033] According to the ingredients and contents (% by weight) described in Table 1 below, a water-in-oil type cosmetic was prepared by the following preparation method.

[0034]

[0035] 1) The oil phase ingredients are mixed and heated to 80°C, and then dispersed.

[0036] 2) The colorant ingredients are mixed and stirred in the above 1).

[0037] 3) Slowly heat the water phase ingredients to 80°C in a separate water phase tank and dissolve completely.

[0038] 4) The water phase component of the above 3) is slowly added to the oil phase component of the above 1), and emulsified using a homomixer.

[0039] 5) After the emulsification is completed, defoam and cool to 28°C.

[0040] [Table 1]

experiment example 1

[0042] Experimental Example 1: A water-in-oil cosmetic formulation comprising an oil phase polymer

[0043] In order to confirm the initial gloss and long-lasting effect of the water-in-oil type cosmetic composition containing the oil phase polymer for smoothing the makeup film, experiments were carried out on the above-mentioned Examples and Comparative Examples.

[0044] The moisture test of the water-in-oil cosmetics of the above-mentioned Examples 2 and 3 was carried out. For run-off measurement, the dosage forms are spread to a thickness of 60 μm on black and white paper and then measured using a gloss meter (Glossmeter VG 2000, 85°). As for the measurement method, the gloss was measured three times immediately after application and after 4 hours and 8 hours, and the average value thereof was used to represent the initial gloss and the reduction rate of gloss. figure 1 The case is to compare the GU* values ​​obtained by the gloss meter according to time, and Table 2 show...

experiment example 2

[0048] Experimental Example 2: A water-in-oil cosmetic formulation containing a water-phase polyol

[0049] In order to confirm the initial gloss and long-lasting effect of applying a polyol having a high refractive index to a water-in-oil type cosmetic composition in a water phase, the formulations of Examples and Comparative Examples in the above Table 1 were prepared and experiments were performed. Gloss meter measurements where high refractive polyols are applied to formulations that do not contain high refractive oils are shown in figure 2 , The gloss reduction rate is shown in Table 3.

[0050] [table 3]

[0051] Gloss reduction rate (%) Comparative example 1 Comparative example 4 Comparative Example 5 Example 1 Reduction rate (4 hours) 48.64 58.66 57.68 42.38 Reduction rate (8 hours) 68.32 77.68 69.43 55.83

[0052] From figure 2 From the results shown in Table 3, it can be confirmed that the water-in-oil cosmetics containing...

Abstract

The present invention relates to a cosmetic composition for sustaining luster and, more specifically to, a cosmetic composition which comprises a highly refractive oil and can alleviate a stuffy feeling of use and enhance the sustainability of skin luster. A water-in-oil type cosmetic composition of the present invention reduces skin stuffiness caused by adapting a highly refractive oil and is far superior in terms of initial luster and luster sustainability.

Description

technical field [0001] This application claims priority based on Korean Application No. 10-2018-0133182 filed on November 1, 2018 and Korean Application No. 10-2019-0075951 filed on June 25, 2019, and the descriptions and accompanying documents of the corresponding applications All the contents disclosed in the drawings are used in this application. [0002] The present invention relates to a cosmetic composition capable of improving skin moisturization staying power. Background technique [0003] In general, emulsions used in cosmetics, pharmaceuticals, foods, etc. are roughly divided into two forms. One is an oil-in-water emulsion in which oil is dispersed in water in a granular state, and the other is a water-in-oil emulsion in which water is dispersed in oil. Compared with the oil-in-water dosage form, the water-in-oil dosage form inhibits the evaporation of water from the skin, so that it can continuously deliver moisture and skin active substances to the skin for a l...
