含推进剂防晒喷雾化妆品取样方式研究
|
摘要
采用含推进剂和不含推进剂的取样方式,分别测定含推进剂防晒喷雾化妆品样品中防晒剂的含量,比较不同取样方式的测定结果差异,为规范该类产品的取样方式提供参考。结果表明,采用去除推进剂后取样测定得到的防晒剂含量测定结果较不去除推进剂取样测定得到的结果准确,且不含推进剂取样方式的测定结果重现性更好,RSD均小于10%。排完推进剂后取样能准确测定含推进剂防晒喷雾化妆品中防晒剂的含量,平行样测定结果重现性良好。
The contents of the sunscreen agents in the sunscreen spray cosmetic samples containing propellant were determined respectively by propellant-containing and propellant-free sampling method, and the results of the two methods were compared to provide a reference for standardizing the sampling method for this kind of cosmetic. Results show that the determination of sunscreen contents by sampling after propellant removal are more accurate than those without propellant removal, and the propellant-free sampling method is more reproducible with RSD less than 10%. The content of sunscreen agents in the sunscreen spray cosmetics containing propellant can be accurately determined by sampling after excluding the propellant. The measurement results of parallel samples have good reproducibility.
