A method for determination of four kinds of chlorinated hydrocarbons in cosmetics was established. The carbon tet-rachloride,trichlorethylene,1 ,1 ,2-trichloroethane and tetrachlorethylene in cosmetics were extracted by headspace method. Then the extracts were detected by GC-MS. The results showed that the standard curve of carbon tetrachloride was Y =18 221 500X-7 338 030,and the correlation coefficient was 0.9994,the average recovery ranged from 71.5% to 112.3% , the minimum detection limit was 0.31 mg/kg in cosmetics. The standard curve of trichlorethylene wasY= 9 633 820X-338 659,and the correlation coefficient was 0.9989,the average recovery ranged from 73.8% to 118.6% ,the minimum detec-tion limit was 0.83 mg/kg in cosmetics. The standard curve of 1 ,1 ,2-trichloroethane wasY= 1 189 350X+953 532,and the correlation coefficient was 0.9985,the average recovery ranged from 81.2% to 109.6% ,the minimum detection limit was 2.5 mg/kg in cosmetics. The standard curve of tetrachlorethylene wasY= 5 738 810X-3 956 440,and the correlation coef-ficient was 0.9979,the average recovery ranged from 75.5% to 111.1% . The minimum detection limit was 0.75 mg/kg in cosmetics.
