纳米材料与化妆品

纳米技术是21世纪最有前途的技术之一.纳米材料由于具有不同于普通材料的物理、化学和生物特性,正越来越多地开发用于多个领域.赋予纳米材料新特性的主要因素是相对表面积的增大和量子效应.用于化妆品的纳米材料有纳米ZnO和TiO2、富勒烯、纳米泡囊、纳米乳剂和纳米微粒等.纳米材料用于化妆品展现明显的优点,其安全性也受到关注.

Nanomaterials and cosmetics

Nanotechnology is the most prospective technology in the twenty-first century. Nanomaterials are increasingly applied in numerous fields due to their physical, chemical and biological properties which are different from conventional materials. Two principal factors cause the properties of nanomaterials to differ significantly from other materials: increased relative surface area and quantum effects. Nanomaterials applied in cosmetics include nano-ZnO and TiO2, fullerene, nanovesicles, nanoemulsions and nanoparticles. Nanomaterials have exhibited obvious benefits in the area of cosmetics, but attention should be paid to their safety.
