摘要
[目的 ]研究SPF 2 90防晒系数分析仪用于评价抗水性防晒化妆品的可能性。 [方法 ]选择 4个标有抗水或防水功能宣传的防晒化妆品和 1个一般的防晒化妆品 ,用SPF 2 90防晒系数分析仪和振荡水槽测定。 [结果 ]SPF 2 90防晒系数分析仪的测定结果与防晒化妆品的宣传基本一致 ;长波紫外辐射 /中波紫外辐射 (UVA/UVB)比值的变化可推断水带走的产品中两类防晒剂的情况 ;水槽温度在 2 0～ 3 0℃、振荡频率在 5 0～ 2 0 0次 /min之间对样品的抗水性测试结果无明显影响。 [结论 ]SPF 2 90防晒系数分析仪可用于分析抗水性产品的防晒功能 ,并可判断配方中哪种吸收剂的疏水能力更强 ;
To study the possibility of assessment on water resistance of sunscreens by SPF 290S Analyzer System. The water resistance of five sunscreens,among these sunscreens four were labelled as water resistant,was assessed by SPF 290S Analyzer System and vibrating flume. The sunscreens labelled as water resistant had significantly better substantivity than that of the products without a label concerning water resistance. The ratio of UVA/UVB may be used to evaluate the water resistance of sunscreens and dissolution characteristics of UVR absorbance. The temperature varied from 20℃ to 30℃ and vibrating frequency varied from 50 times/min to 200 times/min had no effect no sunscreens substantivity. [Conclusion] SPF 290S Analyzer System may be used to assess the water resistance of sunscreens and dissolution characteristics of UVR absorbance. The temperature and vibrating frequency mentioned above had no effect on sunscreens substantivity.
