Dibutyl phthalate | C16H22O4 - PubChem

Dibutyl phthalate is a phthalate ester that is the diester obtained by the formal condensation of the carboxy groups of phthalic acid with two molecules of butan-1-ol.Although used extensively as a plasticiser, it is a ubiquitous environmental contaminant that poses a risk to humans.

Comparing the effects of diethylhexyl phthalate and dibutyl phthalate. Epidemiological studies have shown that high molecular weight phthalates (HMW) such as diethylhexyl phthalate (DEHP), are associated with hypertension in humans, while low molecular weight phthalates (LMW) such as dibutyl phthalate (DBP), have hardly any impact on the elevation of blood pressure.
