The European Union has set a maximum specific migration limit from food contact materials of 9 mg/kg food for the sum of diisononyl phthalates and diisodecyl phthalates.
DINP was listed as a substance "known to the State of California to cause cancer" under Proposition 65 legislation on 2013-12-20.
Yet not only for cause of cancer is this substance known. Generally phtalate esters of higher alkanes (or cykloalkanes) (like dipentyl/hexyl/nonyl phthalate etc.) are harmful to organism , because destruction of their esteric bond puts theese higher alkane/cykloalcane..etc. into organism, though these molecules are heavily degradable and remain to circulate in veins and cause - for example - reproduction issues.source (in Czech)
