Analytic Laboratory Methods
Migration of photo stabilizers from plastics was studied in model elution expt where the plastics were placed at different temp 20 and 45 degree in different solvents, e.g. H2O, acetic acid,  sunflower oil, heptane, and the amt of photostabilizer eluted was determined by spectrophotometry and by gas chromatography. The elution of 2-hydroxy-4-n-octyloxybenzophenone depended on the type of plastic. Elution was low in polystyrene and high in polyolefins, polyethylene. Food contamination from these plastic additives is discussed.
