What are the properties of DIDP and DINP?
DIDP
and DINP
are viscous, oily liquids that are soluble
in fat and not very soluble in water.
They are not very volatile
so they do not vaporise readily into the
atmosphere.
Under the European Union
classification system that applies to
labelling of chemicals in commerce, DIDP
and DINP are not classified as “dangerous
to the environment or human health.
The acronym DIDP
refers to di-isodecyl phthalate.
It is a mixture of closely related substances
known as isomer
which have two carbon chains that can
be 9 to 11 carbons long, with the largest
portion having 10 carbon atoms in the
side chains. The acronym DINP
similarly refers to di-isononyl phthalates
which is a mixture of isomers that have
alkyl
chains form 8 to 10 carbons long,
but the largest portion of the mixture
have chains composed of 9-carbons. The
close similarities between DIDP and DINP,
both in their properties and their end
uses, means that they will be treated
together in the present study. More...
