| Abstract: | A method for determination of methanol in cosmetics by Headspace Gas Chromatography with capillary column was established. The influences of oven temperature, vial equation time,salting-out agent were discussed. Good linear relationship was obtained in the range of 9. 504-594. 0mg/L with correlation coefficient of 0. 99998 and recoveries ranged from 90. 4% to 105. 65% ,the detection limit（S/N=3） was 49.9μg/g. The results indicated that this method was suitable for the determination of methanol in cosmetics. |
