Abstract:
Objective:To establish a method for the determination of phenyl salicylate in compound titanium dioxide cream. Meth-ods:The HPLC assay was carried out on an Agilent Zorbax SB C18 (250 mm × 4. 6 mm, 5 μm) column with methanol -water (78∶22) as the mobile phase. The sample was detected at 308 nm with a UV detector. The column temperature was set at 25 ℃ and the flow rate was 1. 0 ml·min-1 . Results:Phenyl salicylate could isolate from the other materials by HPLC. The linear range of phenyl salicylate was 59.460-198.200 μg·ml-1(r=0.999 5). The recovery was 101.84% with RSD of 0.64%(n=9). The content of phenyl salicylate in 3 batches of compound titanium dioxide cream was 107. 7%, 107. 5% and 109. 8%, respectively. Conclusion:The method is simple, rapid, exclusive, accurate and sensitive, which is suitable for the determination of phenyl salicylate in com-pound titanium dioxide cream.
