The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

According to the results of the Biodegradation test (in read-across from DPX-C), Dibenzetano is not readily biodegradable. QSAR results support this conclusion. No Hydrolysis test could be performed becaouse the substance is not soluble in water. Therefore the criteria for Persistence (P) are expected to be met. Available data does not permit the classification as very Persistent (vP).


No bioaccumulation data on fish are available for Dibenzetano, but, according to the logPOWand toxicokinetics considerations, it is expected to bioaccumulate in living organisms. Therefore, from a precautionary point of view, criteria for classification as Bioaccumulative (B) are met. Available data does not permit the classification as very Bioaccumulative (vB).


According to the 28-day repeated dose toxicity study by oral route in rats (in read-across from DPX-C), the substance is classified as STOT RE 2, H373. Therefore the criteria for the classification as Toxic (T) are met.
