1 Scope

This standard specifies the methyl eugenol in cosmetics by gas chromatography/mass spectrometry. This standard applies to the determination of methyl eugenol agent class, cream lotion, lipstick and other cosmetics. Principle 2 Samples were solvent extracted, centrifuged, the supernatant microporous membrane filtration, and the filtrate was determined by gas chromatography/mass spectrometry, select from Son and retention time qualitative, external standard.
