Reaction mass of Amines, N-tallow alkyltrimethylenedi-, mono(2-ethylhexanoates), Amines, N-tallow alkyltrimethylenedi-, acetates and n-tallow-1,3-diaminopropane ditallate

Endpoint summary

Description of key information

No toxicity tests with terrestrial organisms have been performed with "Reaction mass of Amines, N-tallow alkyltrimethylenedi-, (2-ethylhexanoates), Amines, N-tallow alkyltrimethylenedi-, acetates and n-tallow-1,3 -diaminopropane ditallate" (R814M). The test substance is a salt of tallow-1,3 -diaminopropane (CAS no 1219010 -04 -4) and a mixture of talloil fatty acids, 2 -ethylhexoic and acetic acid.

Under environmental conditions a large extend of the salt is expected to be dissociated and ecotoxicity observed will originate mainly from tallow-1,3 -diaminopropane. No effects (NOEL>=100 mg/L) were observed for the WAF of tall oil fatty acid to algae and daphnids and for 2 -ethyl hexanoic acid the lowest NOEC (21d daphnia) was 25 mg/L (ECHA). Therefore available data on toxicity to terrestrial organisms by alkyl-1,3 -diaminopropanes were included in the dataset. The ecotoxicity of tallow-1,3 -diaminopropane is expected to be reduced when forming a salt with talloil fatty acids or 2 -ethylhexoic acid.

For alkyl-1,3 -diaminopropanes there is one long-term terrestrial test available.

The effects of hydrogenated tallow-1,3 -diaminopropanes on mortality, biomass and reproduction of Eisenia fetida was tested according to OECD 222 under a static exposure for 28 days and no effects were observed upto the highest test concentration of 1000 mg/kg dw. This is NOEC for hydrogenated tallow-1,3 -diaminopropane and this value needs to be recalculated to R814M using the tallow-1,3 -diaminopropane content of 52.2% in R814M. This recalculation results in a NOEC for R814M of 1916 mg/kg dw.

Additional information

Under environmental conditions a large extend of the salt is expected to be dissociated and ecotoxicity observed will originate mainly from tallow-1,3 -diaminopropane. Therefore available data on toxicity to terrestrial organisms by alkyl-1,3 -diaminopropanes were included in the dataset.

For alkyl-1,3 -diaminopropanes there is one long-term terrestrial test available. The effects of tallow-1,3 -diaminopropanes on mortality, biomass and reproduction of Eisenia fetida was tested according to OECD 222 under a static exposure for 28 days. Natural soil (Lufa 2.2) was used as substrate, and the different concentration of the substance mixed with the substrate. The concentrations applied were 125, 250, 500, and 1,000 mg/kg soil dry weight. In addition tests using control and vehicle control were performed.

The test is valid without restrictions and the results are reliable. After 28 days of exposure, no effects on survival of the adult worms were observed in all concentrations. After the following four weeks, no significant effects on the reproduction rate (average number of juveniles) were observed compared to the control. Hence, the NOEC is 1000 mg/kg dw soil. This is however the NOEC for hydrogenated tallow-1,3 -diaminopropane and this value needs to be recalculated to R814M using the tallow-1,3 -diaminopropane content of 52.2% in R814M. This recalculation results in a NOEC for R814M of 1916 mg/kg dw.

The terrestrial PNEC for R814M of 19.16 mg/kg dw is calculated using this PNEC of 1916 mg/kg dw applying an assessment factor of 100.
