National food safety standard Food contact materials and articles Determination of migration amount of benzophenones
Standard in brief
Scope of Application：
This standard specifies the methods for determining the migration levels of eight benzophenone substances in food contact materials and articles.
Part 1: The liquid chromatography (LC) method is applicable to the determination of the migration levels of (2-hydroxy-4-methoxyphenyl)(2-hydroxyphenyl)methanone, 2,4-dihydroxybenzophenone, (2-hydroxy-4-methoxyphenyl)phenylmethanone, 4,4'-dihydroxybenzophenone, 2-hydroxy-4-octyloxybenzophenone, 2-hydroxy-4-hexyloxybenzophenone, benzophenone, and 4,4'-difluorobenzophenone in plastic, coatings and coatings, rubber, and food contact materials and articles using ink, in water, 4% (v/v) acetic acid, 10% (v/v) ethanol, 20% (v/v) ethanol, 50% (v/v) ethanol food simulants, and chemical substitute solvents 95% (v/v) ethanol and isooctane.
Part 2: The liquid chromatography-tandem mass spectrometry (LC-MS/MS) method is applicable to the determination of the migration levels of (2-hydroxy-4-methoxyphenyl)(2-hydroxyphenyl)methanone, 2,4-dihydroxybenzophenone, (2-hydroxy-4-methoxyphenyl)phenylmethanone, 4,4'-dihydroxybenzophenone, 2-hydroxy-4-octyloxybenzophenone, 2-hydroxy-4-hexyloxybenzophenone, benzophenone, and 4,4'-difluorobenzophenone in plastic, coatings and coatings, rubber, and food contact materials and articles using ink, in water, 4% (v/v) acetic acid, 10% (v/v) ethanol, 20% (v/v) ethanol, 50% (v/v) ethanol, olive oil food simulants, and chemical substitute solvents 95% (v/v) ethanol and isooctane.
