Abstract: HPLC method was established for simultaneous determination of 12 kinds of preservatives in cosmetics.Samples were extracted by methanol,then separated by Phenomenex Luna C18 column (4.6 mm×250 mm,5 μm) using acetonitrile and 0.1% phosphoric acid as mobile phase with gradient elution,the detection wavelengths were 280 and 254 nm,and the column temperature was 30 ℃.The calibration curves shows good linear relationship in the range of injection volume and all the correlation coefficients are above 0.996,the average recoveries spiked at 60%,100%,140% are in the range of 95.2%-112.1% with RSD of 0.36%-2.64% (n=9).The method shows good reproducibility and durability through detection of 40 batches of samples.It can be used for simultaneous determination of 12 kinds of preservatives in cosmetics.
