Description

Antioxidant composition enhanced by heat as well as preparation method and application thereof

Technical Field

The application relates to an antioxidant composition enhanced by heat, and a preparation method and application thereof, belonging to the technical field of cosmetics.

Background

Environmental pollution conditions rapidly worsen throughout the world and become more evident in the daily life of consumers. Contamination damage to human skin is also becoming more and more evident. Human skin is subject to various damage by external factors such as Ultraviolet (UV) radiation, environmental pollution, wind, heat, infrared radiation, low humidity, irritating surfactants, abrasives and the like. Recent studies have shown that in addition to UV radiation, other environmental factors also contribute to the development of solar moles, in particular air pollution. Ultimately, these factors cause visible signs of skin damage. Typical skin lesions include fine lines, wrinkles, pigmentation, yellowish-brown, sagging, dark circles, eye puffiness, enlarged pores, visible dead skin, i.e., scaling, dryness and roughness. Besides skin damage, environmental pollution can cause discomfort such as irritation, itching, dryness, roughness, allergy and the like. Inhibition of active oxygen species may be critical to anti-fouling. For example, exhaust particulates and fumes can up-regulate matrix metalloproteins, thereby affecting the integrity of the skin.

Antioxidants are chemicals and biologicals that destroy harmful oxygen radicals, and the use of products containing antioxidant components in daily skin care is a mainstream antioxidant concept today, and antioxidant components and products are many in the market and in various forms. Vitamin C and its derivatives are substances with powerful antioxidant activity, and can slow down skin aging, prevent wrinkles and color spots, inhibit the synthesis of collagenase, promote wound healing, promote skin metabolism, improve skin immunity and strengthen skin. The seaweed oligosaccharide is a saccharide substance obtained by taking marine algae as a raw material through chemical or biological enzymatic degradation, has good antioxidant capacity, can effectively remove common active oxygen free radicals in the body, is beneficial to improving the skin anti-aging capacity, and can have obvious protective effect on skin oxidative damage by improving the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX). However, the stronger the antioxidant activity of the antioxidant, the more easily the antioxidant is oxidized, especially in the case of an increase in temperature, such as skin temperature increase due to sun or exercise; although vitamin C and its derivatives and trehalose have good effects on skin antioxidation and free radical removal, their stability is a major problem in development and utilization, especially at high skin temperature, so how to improve the thermal stability of antioxidants is a problem to be solved by antioxidants at present.

Effect example 1

Effect example the effect of temperature on the antioxidant compositions obtained in each example and comparative example was tested.

Superoxide dismutase (SOD enzyme) is commonly existing in animals and plants, and is an enzyme for scavenging superoxide anion free radicals, and superoxide anion free radicals (O ^2-) are generated through a xanthine and xanthine oxidase reaction system. Superoxide dismutase can be used for determining the enzyme activity by adopting an ultraviolet-visible spectrophotometry method of nitrogen blue tetrazolium. In the presence of an oxidizing substance, riboflavin may be photo-reduced, and the reduced riboflavin is highly susceptible to reoxidation under aerobic conditions to give O ^2-, which reduces azulene to blue methylhydrazone, which has a maximum absorption at 560 nm. Whereas superoxide anion inhibitors (e.g., SOD) scavenge O ^2-, thereby inhibiting the formation of methyl hydrazone. Thus, the deeper the blue color of the reaction solution after the photoreduction reaction, the lower the superoxide anion inhibition capability of the raw material, and the higher the superoxide anion inhibition capability of the raw material, and the capability of the composition for inhibiting superoxide anions can be calculated according to the higher the superoxide anion inhibition capability.

The test method is as follows:

130mmol/L methionine (Met) solution: 1.9389g of Met is weighed, dissolved by phosphate buffer solution and fixed to 100ml; can be stored in a refrigerator at the temperature of 4 ℃ for 1-2 d.

750 Μmol/L solution of Nitrogen Blue Tetrazolium (NBT): weighing 0.06133gNBT, dissolving with phosphate buffer solution to a constant volume of 100ml, and storing in a dark place; can be stored in a refrigerator at the temperature of 4 ℃ for 2-3 d.

20. Mu. Mol/L riboflavin solution: weighing 0.0075g of riboflavin, dissolving with phosphate buffer to 1000mL, and storing in dark.

100. Mu. Mol/L EDTA-2Na solution: 0.0372g of EDTA-2Na was weighed and the volume was set to 1000mL with distilled water.

Sample solution: the mass of the antioxidant compositions obtained in each of the examples and comparative examples in Table 1 was complemented with a sterile PBS buffer so that the total mass of the antioxidant compositions obtained in each of the examples and comparative examples was 100 parts by weight.

The testing steps are as follows:

taking 5 clean and dried transparent ep tubes for each group, numbering, adding each reagent and enzyme solution according to the table 2, and enabling the total volume of a reaction system to be 3mL; after vortex mixing, each tube reacts for 10min under different temperatures (20 ℃,25 ℃, 35 ℃, 40 ℃) and 4000-4500 lx sunlight (the light receiving condition of each tube is required to be consistent, the reaction color and enzyme activity of a control tube under the condition of light are properly adjusted according to the reaction time), and the No. 5 tube is subjected to light-shielding treatment at the same temperature; after the reaction, the reaction was stopped by covering with black cloth, the reaction was terminated with the No. 5 tube as a blank, the absorbance of the reaction solution of the No. 1-4 tube was measured at 560nm, the measurement data was recorded, and each experiment was repeated 3 times.

the SOD activity of the antioxidant compositions obtained in each example and comparative example was calculated as formula 1, with SOD-like enzyme activity expressed as the ability of the sample to inhibit superoxide anions, and known SOD activity units expressed as 50% of the enzyme activity units inhibiting the photochemical reduction of NBT:

SOD total activity (U/mL) = (a ₀-A_s)×V/50％×A₀×V_s (1))

SOD total Activity is expressed as enzyme units per mL of sample (U/mL)

In the formula 1, A ₀ is absorbance of a control tube under light; a _s sample measurement tube absorbance; v, total volume of sample extracting solution (mL); v _s sample extract (mL) was taken during the measurement.

Comparative examples 3-8 show that there is no synergy between the antioxidant compositions in the combination of the two components compared to the individual components alone.

Comparative example 1 and comparative examples 9 to 11 show that the effect of the obtained antioxidant composition is significantly reduced by using superoxide dismutase instead of Thermus thermophilus fermentation product, using chitosan oligosaccharide as trehalose, or using catechin as antioxidant.
