Description
Technical Field
The invention belongs to the technical field of cosmetics, and particularly relates to a natural plant extract composition with effects of relieving, repairing and resisting allergy and application thereof.
Background
Sensitive skin affects the quality of life of people to a large extent. Sensitive skin usually has skin allergy symptoms and discomfort such as redness, itching, dryness, stinging, burning, tightness and the like, and although a specific allergen is difficult to find, the sensitive skin has common points of "skin barrier damage", namely that the skin surface loses normal protective function and loss of skin moisture occurs, so that dryness, desquamation or itching of the skin occurs. Meanwhile, allergens such as germs, pollen, chemical substances and the like on the surface of the skin easily pass through damaged skin barriers and enter the interior of the skin, so that skin inflammatory reaction is further initiated.
At present, cosmetics for treating or relieving skin allergy mainly adopt the thought that antiallergic components are added into the cosmetics, even medicines such as glucocorticoid are adopted for treatment, but repair of skin barrier functions is often neglected, so that the products can lead to thinning of epidermis and dermis after long-term use, the skin barrier functions are damaged, and symptoms such as skin atrophy, telangiectasia and the like appear. Or, most of cosmetics with effects of relieving, repairing and resisting sensitization are common in the market to improve the moisturizing effect so as to achieve the repairing effect.

The data in Table 4 shows that the plant extract compositions provided in examples 1.1 and 2.1 of the present invention significantly inhibit the release of histamine and IL-1α from KU812 cells, indicating that the compositions are effective in inhibiting inflammation and histamine release, thereby improving the condition of allergic skin.
Although the concentration of the natural active ingredient monomer of example 2.1 is one percent of the natural plant extract composition of example 1.1, the effect of inhibiting histamine release and IL-1 alpha release is slightly stronger than that of example 1.1. The experimental results of comparative examples 1.1 to 1.4 and comparative examples 2.1 to 2.4 also had similar tendency to change as in the above examples.
In addition, it was found from the analysis of the experimental results of each comparative example group that the ratio and kind of the amount of each component in the composition had a significant effect on the effect of the composition in inhibiting the release of histamine and IL-1. Alpha. From KU812 cells. For example, when the amounts of cynanchum atratum extract (or cynanchum atratum glycoside) and bletilla striata extract (or bletilla striata glycoside) in the composition are reduced, and the amounts of tetrandrine extract (or tetrandrine) and andrographis paniculata extract (or andrographolide) are correspondingly increased, the effect of the composition of the present invention on inhibiting histamine release and IL-1 alpha release is reduced. Also, when part of the active ingredient is replaced with an ingredient having the same or similar efficacy, the effect of the composition of the present invention in inhibiting histamine release and IL-1. Alpha. Release is also reduced. In addition, it has been found that the various active ingredients in the compositions of the present invention have a significant synergistic effect, which is significantly better than the combination of the first four components and the combination of the second two components when the six active ingredients in the compositions of the present invention are used in combination.
Effect example 3: skin barrier function test for repairing compositions of the present invention
1. Preparation before testing:
(1) Selection of the subjects:
66 subjects, 50 for men and women, between 18-50 years of age, were randomized into 11 groups (6 subjects per group): a cream base, examples 1.1-2.1 and comparative examples 1.1-1.4 and 2.1-2.4.
(2) Other experimental materials:
3% aqueous SDS (sodium dodecyl sulfate);
hyposensitization external adhesive tape (U.S. 3M company)
Mexameter MXI8 red pigment tester (Germany Courage-Khazaka Electronic company)
2. The experimental method comprises the following steps:
the amount of skin erythema was measured with a Mexameter MXl8 red pigment tester at a predetermined test area of the forearm of the subject, and the amount of skin erythema at this time was set to 0 (baseline value). 0.02mL of 3% SDS solution was accurately measured by a pipette, placed in the center of each plaque laboratory, and then applied to the forearm preset area of the volunteer. After 24 hours of application, the plaque tester was removed. After 4 hours, the amount of erythema on the skin was measured, and the amount of erythema at this time was 100%. The same amount of the cream and base of the compositions of the present invention of examples 1.1 to 2.1 and comparative examples 1.1 to 1.4 and 2.1 to 2.4, prepared in the experimental area of the forearm of the subject, respectively, was then applied on days 1 to 3 after the SDS treatment, and the amount of skin erythema was measured 4 hours after each application.
3. Experimental results:
the calculated and consolidated average test results are shown in table 5.
Table 5: test results of the effects of the Natural plant extract composition of the invention on the skin erythema
From the results in table 5, it can be seen that the effect of the cream-based group of subjects on the relief of experimental skin erythema was not ideal during the study.
The data in table 5 shows that the plant extract compositions provided in examples 1.1 and 2.1 of the present invention have a significant alleviating effect on experimental skin erythema in subjects. Although the concentration of the natural active ingredient monomer of example 2.1 is one percent of the natural plant extract composition of example 1.1, its effect of relieving experimental skin erythema is still slightly stronger than that of example 1.1. The experimental results of comparative examples 1.1 to 1.4 and comparative examples 2.1 to 2.4 also had similar tendency to change as in the above examples.
In addition, the experimental results of each comparative example group are analyzed, and the dosage proportion and the type of each component in the composition have obvious influence on the effect of the composition on relieving the erythema of the skin of the subjects. For example, when the amounts of cynanchum atratum extract (or cynanchum atratum glycoside) and bletilla striata extract (or bletilla striata glycoside) in the composition are reduced, and the amounts of tetrandrine extract (or tetrandrine) and andrographis paniculata extract (or andrographolide) are correspondingly increased, the effect of the composition for relieving the erythema on the skin of the subject is reduced. Also, when part of the active ingredient is replaced with an ingredient having the same or similar efficacy, the effect of the composition of the present invention on alleviating experimental erythema is also reduced. In addition, it has been found that the various active ingredients in the compositions of the present invention have a significant synergistic effect, which is significantly better than the combination of the first four components and the combination of the second two components when the six active ingredients in the compositions of the present invention are used in combination.
In summary, the invention breaks the idea of the traditional formula of the soothing, repairing and anti-allergic cosmetics, combines the functions of soothing, anti-inflammatory and anti-irritation with repairing the skin barrier, and the natural plant extract composition comprises various natural active ingredient extracts, has strong synergistic effect of soothing, anti-inflammatory, anti-irritation, repairing and anti-allergic effects, and is mild and non-irritating to the skin.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
