Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance shows a low solubility, rapid hydrolysis under environmental conditions and limited exposure to the environment due to the properties of the process in which liquid AKD is used. Additionally, all users of Liquid AKD utilize wastewater treatment plants.
Conclusion on classification
The lack of adverse effects in aquatic organisms at concentrations exceeding water solubility in combination with lack of effects when solvent was used to increase the soluble fraction leads to the conclusion that no classification is required. The current ready biodegration studu with liquid AKD showed 45% degradations at 28 days. Based on the evaluation of the current available study with the substance and the comparison of the substance with the read-across substance, it's expected that the substance will be assessed to be readily biodegradable in a new additional ready biodegradation study. The rapid hydrolysis and degradation indicate limited potential for chronic exposure and effects, hence also no further classification for the longer term is required.
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.
