Test Method: SATRA TM373
The quantitative determination of butylated hydroxytoluene in packaging materials
Butylated hydroxytoluene (BHT) (2,6-Bis(1,1-dimethylethyl)-4-methylphenol, CAS: 128-37-0) is a highly mobile antioxidant that is known to cause yellowing in light coloured materials under atmospheric conditions. This method is intended to determine the concentration of extractable BHT in a wide range of packaging materials.
A test specimen is extracted for 4 hours at 30°C with constant stirring in an acetone solution containing 5mg/l of internal standard. Detection and quantification are performed using a Gas Chromatograph with Mass Spectrometry (GC-MS).
