Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
To assess the ecotoxicity of Alkyl phosphate and stearyl amine salts (EC = 952-252-4) on terrestrial organisms, it is of importance to consider the most conservative reliable values found for each endpoint. Within a worst case approach, the environmental fate (e-fate) and ecotoxicity of the Alkyl phosphate and stearyl amine salts (EC = 952-252-4) was mainly considered as driven by the properties of the alkylammonium part.
Terrestrial toxicity data on earthworms and toxicity to terrestrial plants are available for equivalent chain length alkylamine and it is appropriate to use these data by a read-across approach for the registered substance. The lowest value observed on terrestrial micro-organisms is observed for Phosphoric acid, octadecyl ester.
Additional information
Toxicity to soil macro organisms
OECD 222 : NOEC of 540 mg/kg soil (calculated eq. Mass of the salt EC = 952-252-4)
Toxicity to terrestrial plants
OECD 208 : NOEC of > 266 mg/kg dw soil (calculated eq. Mass of the salt EC = 952-252-4)
Toxicity to soil micro organisms
OECD 216 : NOEC of 496 mg/kg (calculated eq. Mass of the salt EC = 952-252-4)
PNEC soil is calculated on the basis of the lowest determined effect concentration considering a security factor of 50.
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).
