Description

Technical Field

[0001] The present invention relates to the field of cosmetics, and more particularly, to an eye cream containing caviar extract and a preparation method thereof. Background Art

[0002] The thickness of the eye skin is only 0.5 mm (about 1 / 3 of the facial skin), and the sebaceous glands are sparsely distributed, resulting in a weak barrier function and being vulnerable to oxidative stress and photoaging. Eye cream is a skin care product specifically designed for the eye skin and has occupied an increasingly important position in the cosmetics market in recent years. Due to its weak and easily dry characteristics, the eye skin is more prone to problems such as fine lines, dark circles, and eye bags. The main effects of eye cream are moisturizing, fading fine lines, alleviating dark circles and eye bags, etc. Moisturizing is the basic function of eye cream, which provides long-lasting moisture for the eye skin to prevent dryness and the formation of fine lines. At the same time, anti-aging ingredients in eye cream, such as peptides, retinol, etc., can effectively reduce eye fine lines and improve the elasticity and firmness of the skin. In addition, for the problems of dark circles and eye bags caused by staying up late and stress, specific ingredients in eye cream, such as niacinamide, caffeine, etc., can effectively fade dark circles and reduce eye bag swelling.

[0003] However, the moisturizing effect of the current eye cream products on the market is not excellent enough, and some eye creams have poor stability and single effects, which cannot meet the diversified needs of the market. Summary of the Invention

[0037] The following further describes the features and performance of the present invention in detail in combination with the embodiments.

[0038] Examples 1 - 3

[0039] Prepare each raw material according to the following ratio.

[0040] Table 1 Raw material ratio of Examples 1 - 3

[0041]

[0042]

[0043] In Table 1, the sturgeon caviar extract is: NATUTECH sturgeon caviar extract, and the Bacillus subtilis / soybean fermentation product extract is produced by LABIO, both directly purchased from the market.

[0044] Prepare the caviar eye cream of Examples 1 - 3 and Comparative Examples 1 - 3 according to the following method.

[0045] S1. Add Component A to the stirring pot, homogenize and disperse evenly, heat to 82 - 85 °C, homogenize for 3 minutes, keep warm for 10 minutes, and stir to dissolve evenly;

[0046] S2. Add Component B to the oil phase pot, heat to 82 - 85 °C, keep warm for 10 minutes, and stir to dissolve evenly;

[0047] S3, Pump Component B into the stirring pot and homogenize at high speed (3000 rpm / min) for 5 min. Then add Components C and D and homogenize at high speed (3000 rpm / min) for 5 min;

[0048] S4, After vacuum insulation for 20 min, start cooling down;

[0049] S5, Cool to 40 - 45 °C, add Components E, F, and G and homogenize at low speed (800 rpm / min) for 3 min, and stir evenly;

[0050] S6, Cool to 35 - 38 °C and discharge, then the described caviar eye cream is obtained.

[0051] Comparative Examples 1 - 3

[0052] According to the raw material ratios in Table 2, prepare the raw materials for Comparative Examples 1 - 3.

[0053] Table 2 Raw material ratios of Comparative Examples 1 - 3

[0054]

[0055]

[0056] According to the preparation method of Example 1, prepare the eye creams of Comparative Examples 1 - 3.

[0057] Experimental Example

[0058] According to the following detection standards of QB / T 1857 - 2013, test the heat resistance and stability of the eye creams of Examples 1 - 3 and Comparative Examples 1 - 3, and the results are shown in Table 3.

[0059] Table 3 Stability of each eye cream

[0060]

[0061] It can be concluded from Table 3 that the eye creams of Examples 1 - 3 have good high - temperature stability, without oil separation and stratification. In Comparative Examples 1 and 2, the ratios of each component are unreasonable, so the stability of the eye creams is poor, with oil separation and stratification phenomena. In Comparative Example 3, although the skin conditioner containing sturgeon caviar extract and Bacillus / soybean fermentation product extract is not added, its stability is not affected.

[0062] According to the following method, test the moisturizing effects of the eye creams of Examples 1 - 3 and Comparative Examples 1 - 3:

[0063] Experimental population: Select 50 female volunteers aged 20 - 50 years old, randomly and evenly divided into 5 groups, with 10 in each group. Use the eye creams of Examples 1 - 3 and Comparative Examples 1 - 3 twice a day, once in the morning and once in the evening, for 6 consecutive weeks.

[0064] Using a skin moisture content tester (Cormeter CM825; CK, Germany): The capacitance method was used to measure the moisture content of the skin at the corners of the eyes of each group of volunteers at the second week (2W), fourth week (4W), and sixth week (6W), and the average value was taken. The results are shown in Table 4.

[0065] Table 4 Moisture content of the skin of each group of volunteers (%)

[0066]

[0067]

[0068] It can be seen from Table 4 that the eye creams provided in Examples 1-3 significantly increased the moisture content at the corners of the eyes after use. Compared with Comparative Example 3, in Comparative Example 3, a skin conditioner containing sturgeon roe extract and Bacillus / soybean ferment extract was not added. After continuous use of the eye cream for 4 weeks, the moisture content of the skin was not much different from that of Examples 1-3. However, after using it for another 6 weeks, the increase in the moisture content of the skin was not much. While the eye creams of Examples 1-3 still had excellent moisturizing effects after using for 6 weeks, and the moisture content of the skin at the corners of the eyes was still higher than that in the previous 4 weeks.

[0069] In summary, the eye cream provided by the embodiments of the present invention contains extracts. The extracts take sturgeon roe extract as the core raw material, and are mixed with sodium hyaluronate, Bacillus / soybean ferment extract, lysate of Saccharomyces cerevisiae ferment, and Tremella fuciformis fruit body extract, which significantly improves the moisturizing effect. By controlling the specific components and mass ratio of the thickener and the thickening emulsifier, the combination of the thickener and the thickening emulsifier can significantly improve the stability of the eye cream and has long-term high and low temperature stability.

[0070] The preparation method of the sturgeon roe eye cream provided by the present invention has a simple preparation method and an easy operation method. The sturgeon roe eye cream prepared by this method has better moisturizing effects and good high and low temperature stability.

[0071] The embodiments described above are some, but not all, of the embodiments of the present invention. The detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
