Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 273-224-1 | CAS number: 68953-70-8 The complex combination of alkanolamines from the distillation of reaction products of ammonia and oxirane. It consists predominantly of triethanolamine, diethanolamine and higher amines from the reaction of triethanolamine and oxirane.

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%
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.
