Abstract:

With flaky zinc oxide (F-ZnO) as the core, SiO2 was used to coat the surface of F-ZnO to obtain SiO2 /F-ZnO (SFZ). Then Pro/SiO2 /F-ZnO (PSFZ) was prepared by loading proanthocyanidins (Pro) on SFZ composites. The samples were characterized by FTIR, XRD, TEM, UV and TGA. The results showed that SiO2 uniformly coated on the surface of flake-shaped ZnO particles in amorphous form, and the appropriate coating amount was 15%. Proanthocyanidins formed a uniform layer on the SFZ surface with a suitable loading amount of 20%. The efficacy was evaluated by antioxidant test and in vitro skin-whitening test, and the stability was evaluated by application in the basic formula. The results showed that PSFZ had good free radical scavenging ability and tyrosinase inhibiting ability. In the testing of sun protection indexes, PSFZ composite had better UV-shielding effect than SFZ. The composite still had high stability under the conditions of formulation application and UV irradiation.

Key words: ZnO flake, SiO2, proanthocyanidins, UV shielding, efficacy
