Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Data on the acute and chronic toxicity of the test item in freshwater organisms are available. Toxicity effects were determined to be above the limit of solubility of the test substance.
Aerobic microorganisms:
Based on a screening test to assess the biodegradation in water (OECD 301D) during 28 and 60 days, the NOEC for the toxicity to microorganisms was determined to be 1 mg/L.
Freshwater invertebrates:
The EL50 value for Daphnia magna in an acute toxicity study was determined to be higher than 10 mg/L (WAF) after 48 hours of exposure.
The EL10 value for Daphnia magna in a chronic toxicity study was as determined to be higher than 10 mg/L (WAF) after 21 days of exposure.
Freshwater algae:
The EL50 and EL10 values based on growth rate for Pseudokirchneriella subcapitata were determined to be higher than 100 mg/L (WAF) after 72 hours of exposure.
Freshwater fish:
The LL50 value for Oncorhynchus mykiss was determined to be higher than 10 mg/L (WAF) after 96 hours of exposure in an acute toxicity study.
The NOELR for Pimephales promelas was determined to be higher than 100% v/v saturation after 32 days of exposure in a chronic toxicity study with the analogue substance Reaction mass of N,N’-ethane-1,2-diylbis(12 -hydroxyoctadecan-1-amide), Octadecanamide, 12-hydroxy-N-[2-[(1-oxooctadecyl)amino]ethyl]- and Octadecanoic acid, 12-hydroxy-, 1-hexyl-12-[[2-[(12-hydroxy-1-oxooctadecyl)amino]ethyl]amino]-12 -oxododecyl ester.
No effects were found at any concentration close to the water solubility of the substance and therefore all effects are considered to be greater than the solubility limit for all available acute and chronic toxicity data.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
