Description of key information

Additional information


No information concerning photodegradation in water or soil is available for tetrakis(2-ethylhexyl) benzene-1,2,4,5-tetracarboxylate. This information is not required according to REACH Regulation Annex VIII.


The stability of the substance tetrakis(2-ethylhexyl) benzene-1,2,4,5-tetracarboxylate against hydrolysis was calculated using HYDROWIN from EPI Suite v4.1 software.

A based catalyzed hydrolysis rate constant (Kb) for pH > 8 at 25 deg C equal at 1.316 L/mol-sec was estimated using a structure estimation method. This corresponds to half-lives of 6.1 days at pH 8 and 60.9 days at pH 7.
