Toxicological Characterization of Phthalic Acid

open access: yesToxicological Research, 2011
There has been growing concern about the toxicity of phthalate esters. Phthalate esters are being used widely for the production of perfume, nail varnish, hairsprays and other personal/cosmetic uses. Recently, exposure to phthalates has been assessed by analyzing urine for their metabolites. The parent phthalate is rapidly metabolized to its monoester (

Interacting blends of Styrenated unsaturated poly (ester–amide)s with commercial unsaturated polyester resin (o-phthalic anhydride based)

open access: yesJournal of Saudi Chemical Society, 2014
Unsaturated poly (ester–amide)s resins (UPEAs) were prepared by the reaction between an epoxy resin, namely diglycidyl ether of bisphenol-A (DGEBA) and unsaturated aliphatic bisamic acids (B1–4) using a base catalyst.
