The aim of this project was to systematically investigate the effect of several common additives on the migration of colourants and associated substances. In particular, where applicable, the effect of slip agents and anti-stats that are designed to ‘bloom’ to the surface of plastics was investigated.
This was a follow-on project building on work undertaken in the Food Standards Agency Project A03045, which reported on the migration of colourants and colourant impurities into food simulants. However, in order to avoid over complicating the analyses and to allow colourant related migrants to be readily identified, one variable that was deliberately not investigated in project A03045 was the effect of additives such as slip agents and anti-static. In the process of ‘blooming’ it is possible that the additives may also exaggerate the migration of other substances present, including those originating from colourants.
