Phthalate Di-isodecyl & Di-isononyl phthalates
2. How are DIDP and DINP used?
There are currently four producers of
DINP in the European Union.
The estimated production in
1994 was around 200 000
tonnes of DIDP and 107 000
tonnes of DINP per year (for the then twelve EU Member States)
and the amounts have probably increased since then.
Around 95% of DIDP and
DINP is used in
PVC as a plasticizer. More
than half of the remaining 5% involves
polymer-related uses other
than PVC (e.g. rubbers). The remaining DIDP and DINP are used in
non-polymer applications including anti-corrosion paints,
anti-fouling paints, lacquers, inks, adhesives and
To estimate releases to the environment, the amount of
phthalates included in
articles being used outdoors or indoors as well as their
technical lifetime has to be
Technical lifetimes of different articles containing
DINP range from 5 to 30
years and the largest quantities are used in wires and cables,
flooring, shoe soles and car undercoating.
