Problems solved by technology

[0003] Anti-aging cosmetics currently account for the majority of the cosmetics sales market. Most of the products start with the most important factors of skin aging: photoaging and free radicals, and add ingredients such as superoxide dismutase (SOD), tocopheryl acetate, ascorbic acid , retinol, which hinders free radicals from forming peroxides, has a single effect, and also has problems such as poor stability, easy discoloration and allergies
[0004] Some of the current anti-aging cosmetics use industrial ingredients with strong anti-oxidation properties in order to achieve a good anti-aging effect, and the short-term effect is quick, but long-term use is extremely harmful to the human body; some anti-aging cosmetics add vitamin antioxidants , but the stability of these antioxidants is poor

[0036] Antioxidant effect test

[0037] According to the theory of free radical damage, the generation of free radicals is the main cause of skin aging. Therefore, whether it has the ability to scavenge free radicals is one of the important indicators for evaluating anti-aging skin care products.

[0038] Diphenyl picryl radical (DPPH) is a stable nitrogen-centered free radical. If the test substance can scavenge it, it means that the test substance has reduced hydroxyl radicals, alkyl radicals or peroxy radicals. The role of free radicals. DPPH has a strong absorption at 520nm, and its ethanol aqueous solution is dark purple. After adding the test substance, use a spectrophotometer to measure the decrease in absorbance caused by the removal of DPPH at 520nm. According to the change in absorbance, the ability of the test substance to remove DPPH can be obtained . Other experimental principles for scavenging superoxide anions and hydroxyl radicals are the same as above.

[0047] Skin elasticity effect verification

[0048] The experimental population was divided into 7 groups with 20 people in each group. The subjects were grouped objectively, and they were unaware of the product ingredients, and the influence of psychological factors on the overall product evaluation was excluded. Each group uses the skin care products of Examples 1-7. Before applying the sample, the subjects used the same mild cleanser to clean their faces, and selected symmetrical positions on the left and right sides of the subject's face about 5×5cm 2 The large and small area is used as the experimental area. Apply about 0.5g of the skin care products corresponding to each group. The frequency of use is once in the morning and once every day.

[0049] Before using the skin care products of Examples 1-7, use the elastic probe of the Callegari soft plus skin tester to detect the initial elasticity m of each test site in the test area of ​​each subject 0 Value, repeat 5 times resp...

[0055] The test is divided into a control group and an experimental group. The experimental groups 1-7 are the skin care products prepared in Examples 1-7, respectively, and the control group is divided into 6 groups. Except for the different weight ratios of the three components of marigold extract, grape seed extract, and pomegranate seed extract, the other components are the same as in Example 1. In addition, in each set of experiments, marigold extract, grape seed extract, The total content of the three pomegranate seed extracts in skin care products is the same, but the proportions of the three are different. The specific control group 1 to 6 contains three components: calendula extract, grape seed extract, and pomegranate seed extract. Parts by weight are shown in Table 4:

Abstract

The invention discloses an antioxidation composition. The antioxidation composition is prepared from a calendula officinalis extract, a grape seed extract and a pomegranate seed extract. In the antioxidation composition, the calendula officinalis extract, the grape seed extract and the pomegranate seed extract are compounded and complement with one another in functional component and cost so as tojointly realize synergistic effects; the antioxidation composition has better antioxidation efficacy and high cost performance; meanwhile, the extracts are matched with a carrot extract and a cortexmori extract to further realize the synergistic effects, and a better antioxidant effect is achieved; after the antioxidation composition is used for a long term, better efficacy of nourishing and resisting ageing can be realized from the essence of skin growth. Meanwhile, the invention also discloses a skin-care product containing the composition.

Description

Technical field [0001] The present invention relates to a composition, especially an antioxidant composition and skin care products containing the composition. Background technique [0002] Skin oxidation (that is, aging) is a gradual physiological process, and it is also the result of a combination of genetic, environmental, social and psychological factors. With the improvement of people's living standards, the functional requirements for skin care products are getting higher and higher, and skin care products with anti-aging effects are also emerging one after another. Anti-aging is actually an antioxidant process. The ways of anti-oxidation mainly include: protecting the skin from external environmental stimulation, removing excess free radicals in cells, repairing skin cells and supplementing nutrients. Anti-oxidation of the skin is to prevent the gradual functional changes of the skin due to the passage of time, which is manifested in the prevention of wrinkles, dryness, f...
