Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The rate of hydrolysis of the substance at pH values normally found in the environment (pH 4-9) was determined according to OECD 111 and GLP principles. The test substance shows a pseudo-first order behaviour. Half-life times at 25°C and pH 4, pH 7 and pH 9 were determined to be 17, 4.3 and 19 hours, respectively.
The 'ready' biodegradability of the test substance was assessed using the carbon dioxide (CO2) evolution test (modified Sturm test) according to OECD guideline 301B. Only 1% degradation was observed after 28 days.Based on the obtained results, the substance Polyfunctional polyaziridine, based on TMPTA and Propylene imine was classified as not readily biodegradable.
Based on peer-reviewed published article, logKoc and Koc were calculated (Ref: Franco, A, Trapp, S (2008), Estimation of the soil-water partition coefficient normalized to organic carbon for ionizable organic chemicals, 27, p. 1995-2004.
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.
