Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The biodegradation of amidoamine test item was determined in a Klimisch 1 GLP study according to Part C.4 -C of the Commission Regulation (EC) No 440/2008 and OECD 301 B (CO2 Evolution Test). The test item attained 34% degradation after 28 days and 73% degradation after 56 days and therefore can be considered to be inherently biodegradable according to the OECD Section 3 revised introduction (2006).
A substantial COD elimination of 71% of the test item was determined in a non-GLP Zahn-Wellens test after 3 hours indicating elimination by adsorption to inoculum. Remaining test item after use in exhaust processes in textile mills can be removed quantitatively from the waste water stream by absorption to inoculum or addition of flocculation agents.
The effect of the test item on the respiration rates of STP sludge organisms was determined in a Klimisch 1 GLP study according to OECD 209 and gave a NOEC value of 1000 mg/L, i.e. the substance is not toxic to STP microorganisms.
Besides the adsorption and desorption of amidoamine test item was determined in a Klimisch 1 GLP study according to EC C.19 and OECD 121. The adsorption coefficient (Koc) of the test item has been determined to be greater than 4.27 x 10^5, log10 Koc >5.63. These values indicate that the test item will be essentially immobile in the environment.
Additional information
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.
