Several recently introduced sunscreens were evaluated using test procedures proposed by the Food and Drug Administration. The newer sunscreens proved to be highly protective, possessing Sun Protection Factors (SPF) of 15 or greater. Improvement in efficacy was achieved by the incorporation of a combination of active ingredients at larger concentrations, and by superior vehicle design. A procedure is also described for the laboratory assessment of wash-off resistance, which provides data comparable to those obtained from swimming tests. Two of the tested sunscreens resisted wash-off after 40 minutes of swimming.
使用美国食品药品监督管理局提出的测试程序，对几种最近推出的防晒霜进行了评估。结果证明，新型防晒霜具有很高的防护性，防晒系数（SPF）为15或更高。通过加入更高浓度的活性成分组合以及优化载体设计，防晒效果得到了提高。文中还描述了一种用于实验室评估耐冲洗性的程序，该程序提供的数据与游泳测试获得的数据具有可比性。两种受试防晒霜在游泳40分钟后仍具有耐冲洗性。
