Description of key information

In accordance with Column 2 adaptation statement of REACH Regulation 1907/2006 Annex VII, information requirement section 7.6,  this study does not need to be conducted if, based on structure, surface activity is not expected and no surface-active properties would be predicted for this compound. Surface activity is not a desired property of trimellitic anhydride (TMA) or its hydrolysis product trimellitic acid (TMLA).  Consequently, a test of the surface tension of TMA or TMLA in aqueous solution is not required.    

Key value for chemical safety assessment
