Migration solvents for free isocyanates in food contact materials using experim...

Agglomerated cork stoppers are currently used for still wines, semi-sparkle and gaseous wines, beer and cider. Methylene diphenyl diisocyanate (MDI) is presently the adhesive in use due to its lowest toxicity comparing with toluene diisocyanate (TDI) previously employed. However, free monomeric MDI can migrate from agglomerated cork stoppers to food stuff and this is worrying subject according to food contact m...
