Physicochemical characterization of nanosize zinc oxide and titanium dioxide used as UVR sunscreen agents in cosmetic formulations
Abstract:The physical (particulate) sunscreen agents ZnO and TiO2,are increasingly used to provide UV protection in a wide variety of cosmetic and personal care products.The particle size distribution (PSD) of each oxide directly impacts product performance in two critical ways.First is the UV attenuation efficiency.Second,cosmetically acceptable and aesthetically pleasing products must also be transparent (non-whitening) when applied to the skin.The actual PSD in the final sunscreen formulation is very dependent upon the method of preparation and especially the quality of the oxide dispersion in the particular cosmetic vehicle.ZnO and TiO2 have their own chemical compatibility that must be recognized to obtain maximum performance.This requires a detailed knowledge of the particulate surface chemistry and how that relates to the other (chemical) components in the product.For example,the majority of titanias currently used in cosmetic applications have been surface modified.This results in a very wide,variation of surface chemistry that critically affects dispersibility,especially when formulating mixed oxide systems.All these factors will be reviewed and illustrated.

物化表征纳米氧化锌和二氧化钛作为紫外线防晒剂用于化妆品配方
摘要：物理（颗粒）防晒剂氧化锌和二氧化钛,越来越多地用于提供各种化妆品和个人护理产品种类繁多防紫外线.粒径分布各氧化物（PSD）的直接影响产品性能的两个重要方面.首先是紫外线衰减效率.第二,接受和美观美观产品还必须透明（非美白）时,适用于皮肤.在最后的防晒配方PSD是非常实际的制备方法后,依赖,尤其是在特定的车辆氧化物弥散化妆品的质量.ZnO和TiO2有自己的化学相容性,必须确认以获得最大性能.这需要详细的微粒表面的化学知识,以及如何涉及到其他（化学）在产品组件.例如,大多数目前使用的titanias在化妆品中应用已经表面改性.这在很宽,表面化学变化的严重影响分散效果,尤其在制定混合氧化物系统.所有这些因素将是检讨和说明.
