Abstract:

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.

Key words: sunscreen spray, cosmetic, propellant, sampling method
