Abstract Hybridization of TiO2, which efficiently blocks UVB, with melanoidin, which blocks UVA, was performed. TiO2 microspheres were prepared using surfactant assisted sol–gel method and carboxylation on TiO2 surface was proceeded to introduce chemical binder. Then, dihydroxyacetone was grafted onto the surface of TiO2 by esterification to prepare the melanoidin/TiO2 composites through the Maillard reaction between dihydroxyacetone and Arginine. The melanoidin/TiO2 composites showed not only suppressed photocatalytic activity but also provided the broad UV absorption range from 280 to 400 nm. Furthermore, hybrid composites can reduce white cast phenomena of TiO2, suggesting more promising application of TiO2 in cosmetics.

用于化妆品应用的具有改善的紫外线屏蔽能力和抑制光催化活性的类黑素蛋白/TiO2 复合材料的制备

摘要 进行了有效阻断 UVB 的 TiO2 与阻断 UVA 的类黑素的杂交。使用表面活性剂辅助的溶胶-凝胶法制备 TiO2 微球，并在 TiO2 表面进行羧化以引入化学粘合剂。然后，二羟基丙酮通过酯化作用接枝到二氧化钛表面，通过二羟基丙酮和精氨酸的美拉德反应制备黑素蛋白/二氧化钛复合材料。类黑素/二氧化钛复合材料不仅表现出抑制的光催化活性，而且还提供了从 280 到 400 nm 的宽紫外吸收范围。此外，混合复合材料可以减少二氧化钛的白色铸造现象，表明二氧化钛在化妆品中的应用更有前景。
