摘要

分析了影响防晒霜紫外线防护能力体外评价的因素。结果发现，任何使防晒层在空间上不均匀的因素，如涂抹防晒剂时的定向粘指法、涂抹防晒层的露水化以及标准 PMMA 板的表面粗糙度，都会改变紫外线透过率。为了抑制涂抹防晒层空间不均匀性的产生，开发了新的涂抹程序和新型亲水平板。结合这些新开发的技术所创建的方法成功地提供了可靠、可重复的紫外线防护能力体外评估。

In vitro Evaluation Method of UV Protecting Ability of Sunscreens: Clarifying and Overcoming Problems to Develop New Method

Factors influencing on in vitro evaluation of UV protecting ability of sunscreens were analyzed. It was found that any factors making the sunscreen layer spatially inhomogeneous, such as directional viscous fingering during the sunscreen application, dewetting of applied sunscreen layer, and the surface roughness of the standard PMMA plate, alter the UV transmittance. New application procedure and new type of flat hydrophilic plate were developed for inhibiting the generation of spatial inhomogeneity in applied sunscreen layer. The method created by the combination of these newly developed technologies succeeded in providing reliable and reproducible in vitro evaluation of UV protecting ability.
