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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The safety assessment according to Annex 1 does not indicate the need to investigate further the effects on aquatic organisms. Therefore no chronic fish testing is justified.
Key value for chemical safety assessment
Additional information
The safety assessment according to Annex 1 does not indicate the need to investigate further the effects on aquatic organisms. Therefore no chronic fish testing is justified. In addition, fish are in general less sensitive to the linear alkyl diamines compared to algae and daphnia. The available acute fish data for the diamines category which covers an alkyl chainlength range from C12 to C18 reveal a comparable toxicity, independent of this alkyl chain length.
For the calculation of the PNECaquatic bulk it is considered unlikely that fish toxicity will be critical. Hence any additional toxicity testing with fish will not add scientific value to the ecotoxicity profile of the substance other than for obtaining a lower assessment factor. It is therefore concluded that for scientific reasons and in accordance to REACH legislation further testing on fish has to be avoided for reasons of animal welfare and that based on the weight of evidence available on ecotoxicity data for several cationic surfactants a safety factor of 10 may be applied for the derivation of the PNECaquatic,bulk.
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.
