Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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.

EC number: 269-798-8 | CAS number: 68333-89-1 The non-volatile, high-boiling residue from the distillation of products from cumene-phenol process. It consists predominantly of substituted phenyl groups crosslinked by carbon-oxygen bonds and phenylaliphatic bonds.

Description of key information
Additional information
Biotic degradation is expected to be the predominant pathway for the removal of Z-Oil from the main target compartment (surface waters), whereas hydrolysis as well as photochemical degradation are not considered to significantly contribute to elimination.
Z-Oil proved to be not readily biodegradable in a study conducted according to OECD Guideline 301 D and EU Method C.4 -E (7% degradation after 28 d). The inherent biodegradability of Z-Oil was investigated in a study conducted according to OECD Guideline 302 C. Based on the results of ThOD and BOD measurements, Z-Oil can be considered as inherently biodegradable (52% degradation after 28 d). In the toxicity control containing both test and control substance >80% degradation occurred within 14 d thus indicating that the test item was not inhibitory at the concentration tested.
Experimental studies with Z-Oil adressing the endpoints adsorption and bioaccumulation are not available. Due to exposure considerations and/or technical feasibility of experimental methods, both transport and distribution mechanisms are regarded to be of minor importance. Read-across data on main constituents indicate that no considerable sorption as well as accumulation via the food chain can be expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
