In a further optimized scheme, in the step S2, the content of the absolute ethyl alcohol is 60%, the mass ratio of the honeysuckle leaves to the absolute ethyl alcohol is 1:12, the reaction temperature is 60-70 ℃, and the reaction time is 4-5 hours.
In a further optimized scheme, in step S3, the preparation method of the modified chitosan comprises: dissolving chitosan in acetic acid solution, adding succinic anhydride, mixing uniformly, adjusting the pH value of the solution to 7-8, reacting for 6-8h, adding absolute ethyl alcohol, filtering, extracting for 20-25h, and drying to obtain the modified chitosan.
In a further optimized scheme, in step S1, the microwave extraction power of the white paeony root is 400W; the microwave extraction power of the angelica and the liquorice is 800W.
In a further optimized scheme, the microwave radiation power is 800W, and the radiation temperature is 85 ℃.
The honeysuckle flower leaf extract is prepared by taking the alcohol extract of honeysuckle leaves as the honeysuckle leaf extract, has the advantages of no toxicity, no harm, no allergy, no stimulation and other reactions, can avoid the safety problem existing in the synthesis of the honeysuckle leaf extract, contains a large amount of flavonoids substances in the honeysuckle leaves, has the effects of oxidation resistance, antibiosis, antiphlogosis and the like, and can avoid the influence on the antibiosis due to the fact that the extract contains starch or inorganic salt and other impurities when deionized water is used as the extract. In addition, the application limits that the content of the absolute ethyl alcohol is 60%, the mass ratio of the honeysuckle leaves to the absolute ethyl alcohol is 1:12, the reaction temperature is 60-70 ℃, the reaction time is 4-5h, the extraction amount of flavonoid substances can be increased, and the antibacterial activity of essence is improved. The flavonoids have strong antioxidant effect, and can be used for essence to consume free radicals generated by long-term storage of essence, and prolong whitening and anti-wrinkle effects of essence.
The extracts of the white paeony root, the angelica, the aloe and the liquorice are compounded to prepare a compound angelica extract which is added into the essence to endow the essence with the effects of whitening and lightening spots. Radix Paeoniae alba has antiinflammatory effect, and can be used for treating facial acne and comedo, radix Angelicae sinensis contains abundant amino acids and inorganic salts, and can promote skin metabolism and keep skin clean, Aloe contains abundant vitamins and amino acids, and has speckle reducing, antiinflammatory and skin nourishing effects, and Glycyrrhrizae radix can remove melanin, and has whitening and moisturizing effects. The extract of ginseng, coix seed and safflower is added into the application as a natural humectant, and when the extract is used, the extract can increase the moisture of the horny layer and repair the barrier. The polypeptide has anti-wrinkle effect.
The chitosan reacts with succinic anhydride, and the succinyl chitosan is generated by the reaction of amino and carboxyl, so that the solubility of the chitosan is improved, and then the chitosan reacts with titanium dioxide, and the titanium dioxide can be fixed on the surface of the chitosan and is not easy to fall off, so that the chitosan can absorb ultraviolet rays under various wave bands, and the sun-screening performance of the essence is improved.
The vitamin E is coated by the sodium alginate, the vitamin E has the effects of oxidation resistance and skin aging delaying, but the vitamin E leads oil-soluble substances to be insoluble in water and easily damaged by ultraviolet rays and lose the performance of the vitamin E, therefore, the vitamin E is coated by the sodium alginate at first, the solubility of the microbial E is improved, the microbial E is prevented from being damaged by the ultraviolet rays, the slow release effect is achieved, in order to prevent the vitamin E from being leaked when the sodium alginate is separately coated by the vitamin E, the composite wall material is prepared by compounding the modified chitosan and the sodium alginate, the vitamin E is coated at the same time, the coating rate of the vitamin E is improved by utilizing the excellent solubility and biocompatibility of the modified chitosan, the leakage of the vitamin E is avoided, and the modified chitosan and the sodium alginate can be crosslinked with calcium carbonate to form a network structure, the chitosan can fill up micropores on the surface of the sodium alginate microspheres and reinforce the wall material. When the composite wall material is coated outside the vitamin E, the effect of the vitamin E cannot be influenced because of physical coating, so that the composite microspheres can still have the effects of oxidation resistance, whitening and sun protection. Finally, the composite microspheres are intercalated between the montmorillonite layers, and the montmorillonite is added into the essence by utilizing the adsorbability of the montmorillonite, so that facial grease and toxin can be adsorbed when the montmorillonite is used, and meanwhile, the moisture retention of the essence can be improved by the montmorillonite.
Compared with the prior art, the invention has the following beneficial effects: the essence prepared by the invention has the effects of resisting wrinkles, whitening, moisturizing, resisting oxidation and preventing sunburn, does not cause damage to skin by adopting the components, and is non-toxic and harmless.

And (4) conclusion:
1. the essence prepared by the application has the effects of spot lightening, wrinkle resistance, whitening and oxidation resistance, does not contain irritant substances, can be used by people of any skin type and any age, and does not generate an allergy phenomenon.
2. Compared with the comparative example 1, the comparative example 1 only uses sodium alginate to coat the vitamin E, so that the effect of the essence on the clearance rate of free radicals is better in the early stage, and when the essence is placed for a long time, the clearance rate of the free radicals is reduced, which shows that the condition of leakage can occur when the sodium alginate is used alone to coat the vitamin E, so that the anti-oxygen property is reduced.
3. Compared with the comparative example 2, the comparative example 2 does not modify chitosan and does not add titanium dioxide, so that the free radical clearance is reduced slightly in the later period, and the reduction value of melanin is smaller after the chitosan is modified and the titanium dioxide is added, so that ultraviolet rays can be absorbed, and the increase of melanin is avoided. The chitosan is modified, so that the solubility of the chitosan in an aqueous solution can be improved, the coating rate of the chitosan microspheres is improved, and the vitamin E is prevented from flowing out.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
