Test method of methanol content in detergent].

A test method of methanol content in detergent using a headspace-GC method was established. A 1 g aliquot of test sample was mixed with 0.4 mg of 2-propanol and made up to 20 mL with water. Then, 5 mL of test solution was placed in a headspace vial. The vial was sealed and incubated for 30 min at 60°C, then the headspace gas was analyzed by GC-FID. The recovery from spiked 1 mg/g of methanol was 95.6-100.6%. The determination limit was 0.1 mg/g. Using this method, the methanol content in 14 kinds of detergents was quantified. Methanol was detected from two detergents at the levels of 0.13 and 0.27 mg/g.
