Abstract

The present disclosure relates to an additive composition covering the surface of a cosmetic composition containing vitamin C in order to improve the feeling of use of vitamin C, which is an antioxidant. When the content of vitamin C is increased, there is a tingling sensation and a sticky feeling on the skin, but the additive composition of the present disclosure reduces irritation due to the oil layer and improves stickiness despite the cosmetic composition having a high content of vitamin C In addition, it was possible to provide moisture as well.

Description

Additive composition for improving the feeling of use in cosmetics {AN ADDITIVE COMPOSITION FOR IMPROVING FEELING OF USING COSMETICS}

An object of the present disclosure is to provide an additive composition for improving the feeling of use of a cosmetic composition including an antioxidant.

Specifically, the additive composition may include oil as an active ingredient.

Specifically, the antioxidant material of the present disclosure may be vitamin C, and it is intended to provide an additive composition that improves the feeling of use of the cosmetic composition while containing it in a high content.

Although vitamin C, a representative antioxidant cosmetic ingredient, has excellent antioxidant effects, it is easily altered by oxygen, heat, pH, etc., and its feeling of use is sticky and irritating when used at a high content, so many studies have been done to overcome this.

Korean Registered Patent No. 10-18833040

In the case of pure vitamin C, when it is contained in a high content, stickiness becomes severe, and, in addition, surfactants commonly used in cosmetic compositions may also cause stickiness.

Accordingly, the present disclosure was intended to improve the irritating and sticky feeling of use when containing a high content while preventing oxidation of vitamin C. In addition, it was intended to provide a moisturizing feeling to the skin.

The present disclosure is an additive composition for improving the feeling of use in a cosmetic, wherein the additive composition is for improving the feeling of use of a cosmetic composition of 15% by weight or more of vitamin C, the cosmetic composition does not include a surfactant, and the additive composition is dimethyl as an active ingredient An additive composition comprising at least one oil selected from the group consisting of chicone, methyltrimethicone, hydrogenated C _6-14 olefin polymer, diphenylsiloxy phenyl trimethicone, C _18-21 alkanes, and natural oils. can provide

Evaluation of skin irritation and feeling of use with or without oil

In order to evaluate the presence of an oil layer covering the aqueous layer containing vitamin C, skin irritation and feeling evaluation tests were performed with Comparative Examples 1 and Examples 1 to 4 in Table 1 below.

(1) Evaluation of skin irritation

In order to evaluate the skin irritation of the cosmetic composition, a skin patch test was performed on 20 healthy adults in their 20s and 40s. After shaking and mixing the composition of Table 1, a skin patch test was performed at 20 μl/chamber on the back for 48 hours. The patch was applied for 1 hour, and skin irritation was evaluated at 24 hours and 48 hours after removal, and the results are shown in Table 3 below. Table 2 is a skin irritation scale score table.

Comparative Example 1 was an example without oil, and a large number of people who felt skin irritation appeared. Comparative Example 2 is an example of using cetyl 2-ethyl hexanoate, and the number of persons who felt skin irritation despite including oil was shown to the level of Comparative Example 1 without an oil layer. However, in Examples 1 to 4, the number of people who felt skin irritation was much less than Comparative Examples 1 and 2. Through this, it was found that the degree of skin irritation differed according to the presence or absence of oil as well as the presence or absence of oil.

(2) Sensory evaluation

Moisture and stickiness were evaluated on 20 women in their 20s and 30s. The evaluation was performed by shaking and mixing a composition containing vitamin C and an oil layer and applying it to the skin. The sensory evaluation was performed using a 5-point scale method, and is shown in Table 4 below.

Comparative Example 1 Comparative Example 2 Comparative Example 3 Example 1 Example 2 Example 3 Example 4 moisturizing 1.85 2.75 4.6 4.6 4.5 4.6 3 stickiness 2.05 4.2 4.6 4.65 4.55 4.65 4.25 freshness 1.9 4.3 3.35 3.9 3.65 3.6 4.7

The evaluation criteria were 5 points very good, 4 points excellent, 3 points average, 2 points bad, 1 point very bad. The freshness was evaluated to be 5 points for feeling fresh and 1 point for feeling less freshness.

In the case of vitamin C, the higher the content, the more sticky feeling appears. Accordingly, in the case of Comparative Example 1 not containing the oil layer, the freshness was very low and the result was sticky. In the case of Comparative Example 2, the moisturizing feeling was insufficient. Comparative Example 3 exhibited a moisturizing feeling and stickiness similar to Examples 1 to 4, but the freshness was evaluated as low. However, looking at Table 4, Examples 1 to 4 not only had excellent moisturizing feeling, but also significantly reduced sticky feeling and showed a much fresher feeling compared to Comparative Examples. In particular, in the case of Example 4, the freshness was evaluated very highly, and it was found that it had an excellent effect in improving the feeling of use that was not fresh due to the heavy and wet feeling of vitamin C.

Accordingly, in order to reduce the stimulation level of vitamin C and improve the sticky feeling of use, which is the purpose of the present invention, by combining the skin irritation test and sensory test results, an oil layer should be included as in the present disclosure, and the oil type should be selected and used. And it was found.
