Abstract

The invention discloses a whitening and repairing facial mask containing a leontopodium alpinum extract and a preparation method thereof.

Description

Whitening and repairing mask containing alpine edelweiss extract and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to a whitening and repairing facial mask containing a leontopodium alpinum extract and a preparation method thereof.

Background

With the development of society and the improvement of living standard of people, the requirements of consumers on daily care products are higher and higher, and the requirements on the efficacy of the product are more and more refined. Because of the skin color problem of yellow people, Asian women generally have the problems of dark skin color, dark yellow color, lack of luster, easy allergy, pigmentation and the like. Because of the traditional beauty concept of "one white shading three ugs", the pursuit of whitening by asian women never stops just like the pursuit of brightness by humans. The skin is intended to be the most attractive white, certainly with some facial masks. The secret formula of getting more white and getting better is that the skin whitening mask is required to be prepared. A whitening facial mask is a facial mask added with components with the effects of promoting melanin metabolism, inhibiting and destroying melanin generation, preventing tyrosinase from activating or reducing melanin intermediates and the like. The whitening component must effectively penetrate into the skin substrate to exert the function, and the product is preferably added with a component for promoting cell metabolism.

Although the whitening masks on the market are various in types, the whitening masks such as face masks, tear-off masks, water-washing masks and sleeping masks are all good, the whitening effect is slow to take effect, the traditional preservative is large in irritation, the product is unstable and easy to discolor, and the like.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a whitening and repairing facial mask containing a leontopodium alpinum extract and a preparation method thereof.

The purpose of the invention is realized by adopting the following technical scheme:

Control group 3

The mask of control 3 was prepared in the same manner as in example 3 except that ellagic acid was not added.

Test evaluation

Test 1 test subjects routine experience test

Volunteers included 80 females and 40 males, aged between 20-50 years, and were divided on average into 8 groups, corresponding to examples 1-5 and control groups 1-3, respectively, each group consisting of 10 females and 5 males, respectively, for a test period of 8 weeks. The facial mask of the corresponding group was applied three times a week for 8 weeks to 8 volunteers.

The test of the use experience and the degree of skin improvement before and after the use of the product was evaluated by the volunteers themselves in the form of table evaluation, and the following table shows the evaluation results of the skin-sticking property, air permeability, freshness, moisture retention, safety, repair effect and whitening effect of the volunteers using the product. The test effects are graded, each item is 10 points in total: scores 9-10 are high, indicating good, scores 8-9 indicating good, scores 8-6 indicating acceptable, scores 3-5 indicating poor, and scores 1-2 not acceptable. The evaluation results are shown in the table (the data in the table are average data).

TABLE 1 volunteers assessment of use and degree of skin improvement of examples 1-5 and control groups 1-3

Item	Skin-sticking property	Air permeability	Degree of freshness	Moisture retention	Safety feature	Repairing effect	Whitening effect
								Example 1	8.2	7.8	8.0	8.4	8.8	7.8	6.1
Example 2	8.6	8.3	8.2	8.9	9.0	8.5	7.3
								Example 3	9.2	9.0	8.8	9.4	9.5	9.2	8.2
Example 4	8.5	8.5	9.0	9.3	9.6	9.3	8.0
								Example 5	8.4	8.0	8.8	9.0	9.8	9.4	7.7
Control group 1	9.2	9.0	8.5	8.7	8.8	6.5	8.0
								Control group 2	9.2	9.0	8.9	9.4	9.2	8.8	6.9
Control group 3	9.0	9.0	8.8	9.3	9.4	9.1	6.5

As is clear from table 1, in examples 1 to 5, the skin-adhering, air-permeable, moisturizing, repairing, and whitening effects of example 3 were superior to those of the other examples. In examples 1 to 5, the addition amounts of ellagic acid, carnosine, the flower/leaf extract of leontopodium alpinum and nicotinamide are gradually increased, but the efficacy and effect do not show an increasing effect, so that in the formula, the more the whitening components are, the better the whitening components are, the proper proportion of the components is, and the better effect can be achieved through synergistic effect.

Example 3 and controls 1-3 were the same except that no extract of flowers/leaves of Hibiscus alpina, carnosine or ellagic acid was added. However, compared with example 3, the control group 1 has no added extract of flowers/leaves of leontopodium japonicum, and has a large influence on the moisturizing, safety and repairing effects of the product; compared with the embodiment 3, the control group 2 does not add carnosine, and has larger influence on the repairing, anti-aging and whitening effects of the product; in comparison with example 3, the control group 3 had a greater effect on the whitening effect of the product without adding ellagic acid.

Test 2 whitening repair test

The volunteers were tested for melanin and stratum corneum. The test method comprises the following steps: before test 1, the right half face of each group of volunteers was tested for melanin content and stratum corneum thickness using an MC680 skin tester; after 8 weeks in trial 1, the skin melanin content and the stratum corneum thickness were measured at the same site in each group of volunteers, and the reduction in melanin and the increase in stratum corneum were determined in the following table (the data in the table are mean data).

TABLE 2 volunteers decreased amount of melanin and increased amount of the angle layer for examples 1-5 and controls 1-3

As can be seen from table 2, after the facial masks of examples 1 to 5 and control groups 1 to 3 were used, the skin melanin was decreased to different degrees, and the thickness of the stratum corneum was increased to different degrees, i.e., the facial masks of examples 1 to 5 and control groups 1 to 3 had the whitening and repairing effects.

Among them, the decrease amount of melanin and the increase amount of the thickness of the horny layer in examples 2 to 5 are superior to those in control groups 1 to 3, so that the whitening and repairing effects of examples 2 to 5 are more remarkable. The control group 1 had a greater reduction in melanin than the control group 2 and the control group 3, indicating that the alpine leontopodium flower/leaf extract enhanced the whitening effect. The control group 2 and the control group 3 showed a larger increase in the stratum corneum than the control group 2, indicating that carnosine and ellagic acid enhanced the repairing effect.

Test 3 Patch test

Test article-whitening mask solution prepared in example 3.

Negative control deionized water

The spot sticking method comprises selecting qualified spot tester, dropping 0.020-0.025 mL (semifluid) of the tested object and negative control into the spot tester, applying special adhesive tape (hypoallergenic) on the forearm curve side of the tested object, applying the adhesive tape on the skin by light pressing with palm, removing the tested object after 24 hr, observing skin reaction for 0.5 hr, 24 hr and 48 hr after removal, and recording the result according to skin reaction grading standard in technical Specification for safety of cosmetics (2015 version). The classification criteria are as follows: 0-negative reaction; 1-suspicious reaction, only faint erythema; 2-weak positive reaction (erythema reaction), erythema, infiltration, edema, and possibly pimples; 3-strong positive reaction (herpetic reaction), erythema, infiltration, water, pimples, herpes, which can go beyond the test area; 4-very strong positive reaction (confluent herpes reaction), marked erythema, severe infiltration, edema, confluent herpes, reaction beyond the test area. The number of volunteers with skin reactions of grade 0-4 after 0.5h, 24h and 48h of removal of the test substance was recorded. The test results are shown in Table 3.

TABLE 3 Patch test reaction

As can be seen from table 3, 120 volunteers all showed negative reactions and no adverse reactions after using the whitening and repairing facial mask containing the leontopodium alpinum extract of example 3, which indicates that the facial mask of the present invention is safe and non-irritant after using the natural plant extract as the antiseptic and the anti-allergic agent.
