Description

Technical Field

[0001] The present invention belongs to the technical field of cosmetics, and in particular relates to a composition with antioxidant effect, a preparation method and application thereof. Background Art

[0002] There is a close relationship between aging and oxidation. Oxidation is a natural process in living organisms that involves the production of free radicals. Free radicals are highly reactive molecules that contain unpaired electrons, which makes them very unstable and they will try to steal electrons from other molecules to stabilize themselves. This process of stealing electrons is called oxidative stress. Oxidative stress refers to a state in which when the body is subjected to various harmful stimuli, highly reactive molecules such as reactive oxygen species (ROS) and reactive nitrogen species (RNS) free radicals are overproduced, the degree of oxidation exceeds the ability of oxides to clear, and the oxidative and antioxidant systems are dynamically unbalanced, resulting in cell and tissue damage. Studies have shown that oxidative stress caused by an imbalance in redox levels in the body is the pathophysiological basis of many diseases.

[0003] The human body has natural antioxidant systems, such as glutathione, superoxide dismutase (SOD), and vitamin E, which can neutralize free radicals and reduce oxidative damage. However, as we age, the efficiency of these natural antioxidants may decrease.

[0004] Oxidative stress is one of the important factors that lead to cell damage and aging. By maintaining a healthy lifestyle and using antioxidant products, oxidative damage can be reduced to a certain extent, which may help slow down the aging process. The demand for antioxidant products in the market continues to grow, but there are also some problems: 1. Product stability issues: Many antioxidants, such as vitamin C, are chemically unstable and easily oxidized, which limits their application in products and may affect the long-term effects of the products; 2. Skin feel issues: In order to maintain the stability of the ingredients, some antioxidant products may sacrifice the texture and feel of the product, resulting in greasy or muddy products, affecting the consumer's experience; 3. Irritation issues: Some chemical antioxidant ingredients are highly irritating, such as niacinamide, which may irritate sensitive skin.

[0005] Therefore, it is necessary to develop a mild, non-irritating, and effective antioxidant product. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the above-mentioned prior art. To this end, the present invention provides a composition with antioxidant efficacy and a preparation method and application thereof. The composition provided by the present invention not only has a highly effective antioxidant effect, but is also safe and non-irritating.

[0007] In a first aspect of the present invention, a composition is provided, comprising the following components: an extract of Euterpe tataricum fruit, polysaccharide of Cassia angustifolia seeds and an extract of Terminalia tataricus fruit.

[0008] Specifically, the vegetable E. tamarind extract in the composition of the present invention is rich in amino acids, oils, and high levels of anthocyanins and flavonoids. These ingredients give it antioxidant, anti-inflammatory and skin protection against free radical damage. In addition, it has been proven to be safe for pregnant women and non-comedogenic.

[0009] The fruit extract of Euterpe oleracea has a significant antioxidant effect, and its mechanism mainly involves the following aspects:

[0010] Directly remove or inhibit free radicals: Vegetarian E. tataricus fruit extract contains high concentrations of antioxidants, which can act as a donor of hydrogen protons or electrons to directly quench or inhibit free radicals, terminate the chain reaction of free radicals, and thus exert antioxidant functions. For example, antioxidant ingredients such as polyphenols, sterols and vitamin E can capture high potential free radicals by providing protons, turning them into inactive or more stable compounds.

[0011] Providing electrons: Antioxidant ingredients in the vegetable Etta palm fruit extract, such as polyphenols, plant polysaccharides and vitamins, directly donate electrons through electron transfer to remove free radicals. For example, β-carotene and vitamin C (VC) remove active oxygen free radicals by providing electrons step by step.

[0012] Chelating transition metal ions: Certain components in the vegetable Etta palm fruit extract can chelate transition metal ions, such as iron ions, thereby inhibiting the production of free radicals.

[0013] Influence on oxidase and antioxidant enzymes: Vegetarian Etta palm fruit extract can also exert antioxidant effects by acting on enzymes related to free radicals, such as inhibiting the activity of oxidases or increasing the activity of antioxidant enzymes.

[0014] Specifically, the CASSIA ANGUSTIFOLIA seed polysaccharide in the composition of the present invention has good skin moisturizing and conditioning effects, can improve the moisturizing effect of the product, make the skin smoother, and has significant antioxidant effects, and its mechanism mainly involves the following aspects:

[0015] Free radical scavenging: Plant polysaccharides are usually able to scavenge free radicals in the body, which is one of the important mechanisms of their antioxidant effect. Free radicals are harmful substances produced during metabolism in the body, which can cause cell damage and aging. Senna seed polysaccharides reduce oxidative stress by scavenging free radicals, thereby protecting cells from damage.

[0016] Improve the activity of antioxidant enzymes: Antioxidant enzymes such as superoxide dismutase (SOD) and catalase play an important role in the body's antioxidant function. Senna polysaccharides may enhance the body's antioxidant capacity by increasing the activity of these antioxidant enzymes.

[0017] Inhibit lipid peroxidation: Polysaccharides can reduce the concentration of lipid peroxides and malondialdehyde in the body, which are products of lipid peroxidation and are closely related to cell damage. By inhibiting lipid peroxidation, Cassia angustifolia polysaccharides help protect cell membranes and other lipid structures.

[0018] Regulate immune function: Some studies have shown that plant polysaccharides can regulate the immune system and enhance the body's immune activity. This regulatory effect may indirectly help resist oxidative stress and thus exert an antioxidant effect.

[0019] Specifically, the Terminalia Ferdinandiana fruit extract in the composition of the present invention is a natural ingredient with multiple biological activities, and has significant antioxidant, antibacterial and anti-inflammatory effects, and its antioxidant mechanism mainly involves the following aspects:

[0020] Directly remove free radicals: Polyphenol compounds in Terminalia tataricus fruit extract, such as vitamin C and rutin, can directly remove free radicals and terminate the chain reaction of free radicals, thereby exerting antioxidant function. These antioxidant ingredients capture high potential free radicals by providing protons or electrons, turning them into inactive or relatively stable compounds.

[0021] Inhibit oxidase activity: The antioxidant components in Terminalia tataricus fruit extract can inhibit the activity of enzymes related to free radicals, such as superoxide dismutase (SOD), thereby reducing the generation of free radicals.

[0022] Chelating transition metal ions: The antioxidant components in Terminalia tataricus fruit extract can also chelate transition metal ions, such as iron and copper, which play an important role in catalyzing the generation of free radicals. By chelating these metal ions, the generation of free radicals can be effectively inhibited.

[0023] Enhance the activity of antioxidant enzymes: Certain components in Terminalia tataricus fruit extract can promote the activity of antioxidant enzymes in the body, such as superoxide dismutase (SOD) and glutathione peroxidase (GPx), thereby enhancing the body's antioxidant capacity.

[0024] High content of vitamin C: Terminalia tataricus fruit extract is rich in vitamin C, and its content is 100 times that of ordinary oranges. This high concentration of vitamin C has a strong antioxidant capacity, which can neutralize active oxygen species, inhibit the production of free radicals, and promote the regeneration of other antioxidants.

[0025] The present invention combines the fruit extract of Euterpe oleracea, the seed polysaccharide of Cassia angustifolia and the fruit extract of Terminalia ferdinandiana, and finds that the combination of these components shows a good synergistic effect in anti-oxidation.

[0026] In some embodiments of the present invention, the composition comprises the following components, measured by weight: 0.01-10 parts of Euterpe tataricum fruit extract, 0.01-5 parts of Senna angustifolia seed polysaccharide and 0.01-5 parts of Terminalia tataricus fruit extract.
