The invention discloses a protective system for efficiently neutralizing free radicals produced by inorganic sunscreen agents, a test method and applications thereof. The protection system includes a combination of inorganic sunscreens (titanium dioxide or zinc oxide) and antioxidants, which can efficiently neutralize free radicals produced by inorganic sunscreens under ultraviolet light. Experiments have shown that 1,1-diphenyl-2-tri As determined by the nitrophenylhydrazine (DPPH) method, the residual rate of free radicals does not exceed 10%. |
