A preparation method of microcapsules with anti-pollution effect

Abstract

The invention relates to a method for preparing microcapsules with anti-pollution effects. The method comprises A, weighing gelatin, acacia and distilled water according to the mass ratio and preparing a gelatin aqueous solution and an acacia aqueous solution, B, weighing quercus robur root extract, isosorbitol diocyanate, Norway spruce leaf extract and brown algae polyphenol according to a mass ratio of 2-6: 3-8: 3-5: 1, mixing the materials to obtain an anti-pollution active composition, mixing the anti-pollution active composition and the acacia aqueous solution in an water bath at 25-55 DEG C, adding yeast extract into the mixture, carrying out ultrasonic emulsification, adding the gelatin aqueous solution into the emulsion, adding an acetic acid solution to adjust system pH, carryingout a condensation reaction process and cooling the reaction product to the room temperature, C, putting the reaction product in a cold water bath at 5-10 DEG C, adding a formaldehyde solution into the solution for crosslinking curing and standing the cured material to obtain a microcapsule sedimentation liquid, and D, filtering the microcapsule sedimentation liquid, washing the filter residues and drying the filter residues to obtain anti-pollution microcapsules. The anti-pollution microcapsules have good stability, are easy to use and can help the skin resist different environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of cosmetic preparation, in particular to a method for preparing microcapsules with anti-pollution effect. [0002] technical background [0003] With the continuous development of the global urbanization process, people's living environment is also destroyed: coal burning and vehicle exhaust bring PM2.5 particles; the extensive use of chemicals such as chlorofluorocarbons leads to the decomposition of ozone in the stratosphere The intensity of ultraviolet rays reaching the ground is enhanced; nitrogen oxides and hydrocarbons in automobile exhaust and industrial waste gas undergo photochemical reactions under the action of ultraviolet light to generate ozone (O 3 ), peroxide acetyl (PAN) and other secondary pollutants, mixed with primary pollutants to form photochemical smog. The above-mentioned pollution factors are invading people's skin all the time, causing skin problems such as rough skin, sensitivity, ...

AI Technical Summary

Problems solved by technology

However, most of the active ingredients with anti-pollution effect are unstable, especially the anti-oxidative damage ingredients are mostly reductive, easy to contact with air during storage and use, oxidized by oxygen to lose activity, and even darken the color

There are also some active ingredients that have defects such as dark color and heavy odor. If these active ingredients are directly added to skin care products, it will lead to problems such as unsightly color and unacceptable fragrance of the skin care product cream, which will affect the feeling of use.

Restricted by the above factors, most of the existing skin care products with anti-pollution effects can only start from one aspect of cleaning, isolation, and repair, and cannot fully resist the damage caused by environmental pollution to the skin. Achieve multiple anti-pollution effects in
