DINP is a phthalate that is mainly used as additives in plastics to make them
more flexible. Its structure and applications are very similar to those of
DIDP. It has been widely used in everyday
products, ranging from floorings to shoe soles.
In the 1990s, around 95% of DINP was used in
PVC as a
plasticiser. More than half of the
remaining 5% was used in the production of polymers other than PVC (e.g.
rubbers). The remaining DINP was used in non-polymer applications including
inks, adhesives and sealants, paints and lacquers.
At present, DINP is banned in toys and childcare articles that children can
put into their mouths (see
European Directive 2005/84/EC).
