摘 要：Zinc oxide,which has photocatalytic activity,is used as white pigment for cosmetics.A certain degree of sebum on the skin is decomposed by ultraviolet radiation in sunlight.In this work,zinc oxide was shaken with phosphoric acid to synthesize a white pigment for cosmetics.Zinc oxide was set with 0.1 mol/L of phosphoric acid at P/Zn=1/1 and 1/2,and then shaking in hot water for 1 h.The chemical composition,powder properties,photocatalytic activity,color phase,and smoothness of the obtained powder were studied.The P/Zn ratio in preparation had an effect on the reaction between phosphoric acid and zinc oxide.The photocatalytic activity of zinc oxide was inhibited by phosphoric acid treatment.The obtained samples had enough high reflectance at the visible light region.
