Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Short-term toxicity to fish:

In an OECD 203 test fish (Danio rerio) were exposed 96 h against the test substance. The LC 50 was determined to be 0.150 mg/l. A further poorly documented study (regarded as supporting study ) is described in the literature without GLP and no analytics. The LC50 in zebrafish is reported to be 0.094 mg/l after 144 h.


Long-term toxicity to fish:

not required in the tonnage band 10 -100 t


Short-term toxicity to aquatic invertebrates:

In an OECD 202 test the medium effect concentration (EC50) for Quaternary ammonium compounds, tri-C8-10-alkylmethyl, chlorides after 48 h of exposure against Daphnia magna based on the nominal loading rates was calculated to be 0.160 mg/l (95% confidence limits: 0.143–0.182 mg/l).

Toxicity to aquatic algae and cyanobacteria:

In an OECD 201 test using Desmodesmus subspicatus the aquatic toxicity to algae after 72 h was determined. The median effect concentration with respect to growth rate ErC50of Quaternary ammonium compounds, tri-C8-10-alkylmethyl, chlorides, to Desmodesmus subspicatus was calculated to be 0.290 mg/l loading rate. The ErC10 for 72 h was deterimined to be 0.138 mg/L.


Toxicity to microorganisms:

A valid OECD 209 study is available. The reported EC10 is 4.4 mg/l and the EC50 is 18 mg/l after 3 hours of incubation. No deviations from the test guidelines or other incidents occurred during the course of the reported test which may have influenced the results.
