A method has been established for the analysis of presevatives and antioxidants in cosmetics.Reversed phase high performance liquid chromatography(RP-HPLC) was used for separation and determination of nipagin esters and TBHQ in cosmetics.The components were analyzed by Diamonsil C18(5 μm,250 mm×4.6 mm i.d.)using a UV detector at 254 nm.The mobile phase was methanol water(V∶V=72∶28) at a flow rate of 1.0 mL/min.The methodology exhibited good linearity between 1—100 ng/L.The detection limits range were 0.05—0.1 ng/L.The average recovery ranged from 82.9%—96.3% with RSD ranged from1.17%—2.64 %.
