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 any skin and age group, and does not generate anaphylaxis.
2. Examples 1-4 are compared with comparative example 1, in comparative example 1, only sodium alginate is used for coating vitamin E, so that the scavenging rate of essence to free radicals is better in the early stage, and when the essence is placed for a long time, the scavenging rate of free radicals is reduced, which indicates that leakage occurs when sodium alginate is used for coating vitamin E alone, and the oxidation resistance is reduced.
3. Examples 1-4 are compared with comparative example 2, comparative example 2 did not modify chitosan, nor did titanium dioxide be added, resulting in a small decrease in free radical scavenging rate at the later stage, and the decrease in melanin values was small after use by volunteers, indicating that modification of chitosan, and uv absorption was achieved after titanium dioxide addition, avoiding melanin elevation. The chitosan is modified, so that the solubility of chitosan in aqueous solution can be improved, the coating rate of chitosan microspheres can be improved, and the outflow of vitamin E can be avoided.
