Specification: 30m*0.25mm*0.25um

Model: SE-54

Application: GB/T 31407-2015 Determination of Iodopropynol Butyl Carbamate in Cosmetics Gas Chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography-mass spectrometry method for the determination of iodopropynol butyl carbamate in facial masks of skin care products. Method The sample was extracted with ether, ultrasonic for 15min, and centrifuged at 3 500r/min for 15min. The extract was dehydrated by anhydrous sodium sulfate and concentrated. The residue was fixed to volume with 1.0mL acetone, and the gas chromatography-mass spectrometry was carried out. 30m×0.25mm, 0.25μm) after separation, SIM scanning mode, external standard method for quantification. Results Iodopropynol butyl carbamate has a good linear relationship in the concentration range of 0.1-10 μg/mL (r=0.999 3); in the range of 0.5-1.5 μg/g addition level, the recovery rate is 90.0%-94.67%. The relative standard deviation (RSD) is 3.4%~5.4%; the limit of detection (LOD) is 0.01 μg/g, and the limit of quantification (LOQ) is 0.05 μg/g. Conclusion The method is simple, rapid and reproducible. It is suitable for the determination of iodopropynol butyl carbamate in facial masks of skin care products.
