Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Abiotic Degradation:

In the atmosphere DMF is expected to be indirectly photodegraded with a half life of 2 hours (GDCh, 1991). Photodegradation in water occurs with a half life of 50 days (Haag et al., 1991). Hydrolysis is not expected under environmental conditions.

Biodegradation:

In laboratory tests ready biodegradability was demonstrated for DMF (BASF, 1989). DMF also degraded completely in river water within 6 days (Dojlido, 1979). An inherent biodegradation study (following OECD 302-B test design) confirmed the rapid elimination of DMF from water (BASF, 1976).

Stability:

In the atmosphere DMF is expected to be indirectly photodegraded with a half-life of 2 hours (CDCh, 1991).

Photodegradation in water occurs with a half-life of 50 days (Haag et.al., 1991). Hydrolysis is not expected under environmental conditions.

Bioaccumulation:

Does not significantly accumulate in organisms.

Bioaccumulation in aquatic species: fish (OECD Guideline 305 C, GLP compliance not specified): BCF range of 0.3 -1.2 L/kg indicates a very low bioaccumulation potential.

Transport and Distribution:

QSAR using KOCWIN, v2.00 (which is part of the EPI-Win software package (Version 4.11) of US-EPA): Koc = 1, log Koc = 0

QSAR using HENRYWIN v3.20 (which is part of EPI Suite v4.11): H = 0.00748 Pa m³/mol at 25 °C.

In air DMF shows a distribution level of 11.5% and in water 88.5 %. Based on the calculation it is not expected to appear in soil, sediments and biota.
