Diisononyl phthalate (DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid.
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.[2]
DINP was listed as a substance "known to the State of California to cause cancer" under Proposition 65 legislation on 2013-12-20.[3]
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 these higher alkane/cykloalcane..etc. into organism, though these molecules are heavily degradable and remain to circulate in veins and cause - for example - reproduction issues.[4] source (in Czech)
