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.

Additional information

Tetrahydronaphthalene can be regarded as biodegradable chemical. Whereas the closed bottle test revealed only 5% biodegradation within 28 days (Hüls AG, 1996) the BODIS test resulted in 81% biodegradation after 28 days (Hüls AG 1989). The Scientific Committee on Health and Environmental Risks (SCHER) of the European Commission indicates that the ISO 10708 test is comparable in terms of the methodology to the tests on ultimate biodegradability described in Annex III of the Regulation 648/2004, and that the ISO 10708 provides an equivalent level of reliability and stringency to the international test methods on ultimate biodegradability.

Moreover, there are numerous data that indicate that tetrahydronaphthalene is biodegraded by certain bacteria strains or that it is used as carbon and energy source. Therefore, tetrahydronaphthalene is expected to biodegrade well in the environment, as already concluded by the OECD SIDS evaluation (SIAM 19).
