[Determination of antioxidants butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) in cosmetics by gas chromatography-mass spectrometry selected ion method].
A new method for the determination of butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) in cosmetics by gas chromatography-mass spectrometry selected ion storage (SIS) method was developed. The BHA and BHT in samples were extracted by methanol. The m/z 165 and m/z 205 were the monitoring ion for BHA and BHT respectively. The detection limits of BHA and BHT in samples were 2.5 micrograms/g and 0.5 microgram/g, respectively. The method is simple, rapid and accurate.
