Description of key information

According to the ready biodegradability of the AMIX TE (CAS 68953 -70 -8) and the structural properties of the components, hydrolysis is not expected.

Key value for chemical safety assessment

Additional information

In accordance with section 2 of REACH Annex VIII, the study does not need to be conducted as AMIX TE (CAS 68953 -70 -8) is readily biodegradable (BASF AG, 1996; project no. 95/0675/21/1). Its major components are substances which lack hydrolytically reactive functional groups (e.g. alcohols, olefins, ethers, amines), hydrolysis is not expected to be an important fate process (Harris 1990, Boethling & Mackey 2000). The following three substances are the main constituents of AMIX TE:

- 2,2’,2’’-Nitriloethanol (CAS 102-71-6): typical concentration: 86%

- 2,2’-[[2-(2-Hydroxyethoxy)ethyl]imino]bisethanol (CAS 17626-34-5): typical conc.: 6%

- Piperazine-1,4-diethanol (CAS 122-96-3): typical conc.: 0.1%
