Diisopropyl phthalate  (Synonyms: DiPP)

Diisopropyl phthalate (DiPP) is a phthalate diester, which is widely used as an additive in plastics and consumer products. Diisopropyl phthalate has a weak binding ability to the recombinant human estrogen receptor, with an IC₅₀ of 41000 μM^[1][2][3].

Diisopropyl phthalate can be detected in honey and royal jelly^[2].
