Abstract:

A new method was developed for the determination of methyl methacrylate (MMA) in cosmetics by headspace gas chromatography (HS-GC). After being dissolved in acetone, the samples were determined by headspace gas chromatography-hydrogen flame ionization detector (HS-GC-FID) and quantified by external standard method. The LOD and LOQ of method were 6 and 20 mg/kg, respectively. There existed a good linearity for the MMA in the mass concentration range of 10~500 mg/L, with the correlation coefficient of 0.999 7. The average recoveries of MMA in the cosmetics (water-based, powder, emulsion, oiliness) were in the ranges of 98.2%~103.0% with their RSDs of 2.8%~7.6%. The optimized method is accurate, rapid and sensitive with simple pretreatment. It has been validated by eight testing institutions , and is suitable for the determination of MMA in cosmetics (water-based, powder, emulsion, oiliness).

Key words: cosmetics, methyl methacrylate, headspace gas chromatography
