Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Based on Lead registrant dossier (Annex VII), the registered substance is not readily biodegradable but  a primary biodegradation is demonstrated as the substance is totally converted to a transformation product (salicylic acid, CAS n°69-72-7). This transformation product is readily biodegradable according to OECD TG 301C with 88.1% of biodegradation (CERI, 1975), therefore the registered substance can not be considered as potential Persistent (P) or very Persistent (vP) in the environment.

In the current partial opt-out dossier (Annex VIII), no hydrolysis is expected based on chemical structure of the substance. With a a log Koc values at 1.57 (Koc = 37 L/kg), the registered substance is considered highly mobile in soils according to Mc Call (1981). With a log Kow value at 1.66, the substance is not considered to be bioaccumulative according to CLP (< 4.0) and PBT criteria (< 4.5).

Additional information

This dossier is a partial opt-out dossier including only endpoints of Annex VIII (hydrolysis and adsorption/desorption). Annex VII endpoint (biodegradation) is available in the dossier of the lead registrant.
