Benzophenone-3,3',4, 4'-tetracarboxylic dianhydride (BTDA) is used as intermediate and in polycondensation (fiber and powder production) to manufacture plastic products or fine chemicals in the industrial sector. Consumer risk is very unlikely as BTDA is manufactured and handled under closed conditions in industrial settings only. The environmental effects, ecotoxicology and toxicology information available for BTDA is provided based on studies and/or a reliable evaluation of its hazardous properties.
