Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 272-729-4 | CAS number: 68910-05-4 A complex residuum from the fractionation of the reaction products of 2-aminoethanol with ammonia to remove piperazine. It may contain such compounds as 2-[(2-aminoethyl)amino]ethanol, (aminoethyl)piperazine, (hydroxyethyl)piperazine.
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Ethanol, 2-amino-, reaction products with ammonia, by-products from (CAS-# 68910-05-4) is assessed to be not readily biodegradable taking into account data from the components of the product. Consequently, based on the available data on abiotic and biotic degradation, the product should be considered persistent (presumably “P”) and potentially very persistent (potentially “vP”), in absence of any other data as the screening-criteria for persistence are fulfilled. Based on measured or calculated log Pow values of the different components, Ethanol, 2-amino-, reaction products with ammonia, by-products from (CAS-# 68910-05-4) is not expected to accumulate in organisms and therefore does not fulfill B/vB-criteria. Ethanol, 2-amino-, reaction products with ammonia, by-products from (CAS-# 68910-05-4) is regarded as “T”, since one component (2 -(2 -Aminoethylamino)ethanol (CAS 111 -41 -1)) holds relevant classification: toxic for reproduction (cat 1B) according to the Regulation EC No 1272/2008 (T). In conclusion, 2-amino-, reaction products with ammonia, by-products from (CAS-# 68910-05-4) is not PBT/vPvB.
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.
