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.
