Determination of 2-Chloroacetamide in Cosmetics by Gas Chromatography
Gas Chromatographic Determination of 2-Chloroacetamide in Cosmetics Details:

Name: capillary column

Fixative: polyethylene glycol

Specifications: 30m*0.32mm*0.25um

Model: HH-WAX

Application: SN/T 4347-2015 Determination of Chloroacetamide in import and Export Cosmetics-Gas Chromatography

 2-Chloroacetamide is a preservative used in cosmetics. This product is toxic to oral administration and is irritating to the respiratory system and skin. It is specified as a restricted substance in GB7916-1987, and the maximum allowable concentration in cosmetics is 0.3%. .

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a gas chromatography method for the determination of 2-chloroacetamide in cosmetics. Methods The samples were dissolved in ethanol, homogenized by ultrasonic, centrifuged, separated by HH-Wax chromatographic column, and detected by hydrogen flame ionization detector. Results When the concentration of 2-chloroacetamide was in the range of 0.0～10.0mg/ml, the linearity of the method was good, the detection limit was less than 0.01μg, the relative standard deviation was less than 5.6%, and the recovery was 90%～100%. Conclusion The method is simple, rapid and sensitive, suitable for the determination of 2-chloroacetamide in cosmetics.
