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.

Additional information

The inherent biodegradability of N,N-dimethylisopropylamine (DMIPA) has been evaluated according to OECD 302B guideline using activated sludge taken from a BASF waste water treatment plant treating industrial sewage (study report, 1981). The substance has been found to be not easily eliminated from water since only 29% of degradation (DOC removal) was observed after 28days.

DMIPA can be considered as not inherently biodegradable.

As a supporting study, the readily biodegradability of DMIPA was evaluated according to ISO 7827 (Evaluation in an Aqueous Medium of the "Ultimate" Aerobic Biodegradability of Organic Compounds - Method by Anlaysis of Dissolved Organic Carbon (DOC)). The substance has been found to be not readily biodegradable with a maximum degradation of 5% obtained after 14 days.

A test performed on an analogue substance, ethyldiisopropylamine (EDIPA CAS 7087 -68 -5), was also used as a supporting study. The biodegradability of EDIPA has been evaluated according to OECD 301D guideline. After 28 days, the biodegradation of EDIPA was 2% and thus, similarly to DMIPA, EDIPA was considered as not readily biodegradable.
