Description

A cosmetic composition comprising methyl hydrogenated rosinate

It relates to a cosmetic composition for improving skin gloss comprising methylhydrogenated rosinate.

Recently, as the demand for cosmetics that give luster or shine increases, the need for developing a mask sheet that gives gloss is emerging. Now, in skin care, beyond the effects of exfoliation and whitening, as customers' demand for instant gloss and shine after using cosmetics increases, it is possible to improve the radiance of the applied skin when applied to the skin. There is a need for research on cosmetic compositions that can help.

In general, the method of imparting luster is to use oil, but since oil is an oil-soluble raw material, there are many raw materials that can be used in makeup rather than skin care, and in particular, it is a method that can be used only in the W/O formulation. In addition, in the solubilization formulation, there is little used as a raw material to give a radiance, so a solution for a cosmetic composition that can give a refreshing and light feeling of use is an urgent part.

Among them, the cosmetic composition that can be used in the mask sheet is mostly solubilized type, so it is intended to develop a raw material that gives the solubilization type brilliance. We would like to develop a product that gives brilliance with a mask sheet to which this is applied.

2 points: bad

1 point: very bad

Comparative Example 1 Example 1 Comparative Example 2 luster improvement 2 4 5 moisturizing One 5 4 stickiness 5 4 One absorbency 4.5 4 One

As confirmed in the results of Table 3, the degree of gloss improvement was the highest in Comparative Example 2 with a high content of methylhydrogenated rosinate, but it was confirmed that the score was lowered due to the severe stickiness and slow absorption after use. On the other hand, Comparative Example 1, which had a low content of methylhydrogenated rosinate, showed a high score for stickiness and absorbency, but it was confirmed that the lowest score appeared in the degree of skin gloss improvement. Overall, it was confirmed that Example 1, in which methylhydrogenated rosinate was contained in an amount of 0.3 to 3% by weight relative to the total weight of the composition, had the best skin gloss improvement effect, and also showed excellent effects in moisturizing, stickiness and absorbency.

Experimental Example 3. Confirmation of skin luster improvement effect of methylhydrogenated rosinate-containing cosmetic composition compared to conventional cosmetic composition

An experiment was conducted to determine whether the cosmetic composition having the composition of Example 1 could significantly improve the skin's luster and gloss compared to the conventional cosmetic composition (Control Example 1) containing methylhydrogenated rosinate as one component in the composition. . The cosmetic compositions of Control Example 1 and Example 1 were applied to the skin for about 20 minutes to 20 healthy males/females and sufficiently absorbed, and then improved gloss, moisture, stickiness, and absorbency were confirmed. Gloss improvement was calculated as a percentage of the improvement through clinical trials, and other scores were evaluated based on the following criteria. The results are shown in Table 4. Scores were reported as average values.

5 points: very good

4 points: good

3 points: average

2 points: bad

1 point: very bad
