DIBP is a phthalate and an additive used to keep plastics soft or more
flexible (plasticiser), often in combination with other phthalates.
DIBP is used in nitro cellulose plastic, nail polish, explosive material,
lacquer manufacturing, etc.
DIBP has so far not been evaluated at EU level and is not subjected to any EU
ban.
Because DIBP has very similar application properties to
DBP which was banned in toys and childcare
articles as well as in cosmetics, it may therefore be used as a substitute, for
instance in PVC, paints, printing inks and adhesives.
