Description of key information
Additional information
OECD Guideline-conform studies have been conducted in order to define the acute toxicity of GALDEN LMW to algae, aquatic invertebrates and fishes. All the studies have been performed under GLP, according to OECD guideline.
Under all the studies a high decrease in test item concentration in water has been observed during the exposure period. These analytical results have been ascribed mainly to losses for volatilization occurred during handling and exposure. Due to its physical and chemical properties the product tends to volatilize quickly from water to the gaseous compartment.
In all the studies, no biological effects have been observed at the maximum limit of solubility achievable under test conditions. Basing on these results GALDEN LMW is not expected to be acutely toxic to aquatic organism according to GHS criteria.
Even if the substance is not expected to distribute significantly into water compartment and therefore exposure of aquatic organism is considered negligible, it is not ready biodegradable, has a Partition coefficient Log Kow > 4 and it is poorly soluble in water, thus it fulfills the criteria to be classified in Aquatic Chronic Category 4 according to CLP and GHS definitions. A long-term toxicity study on invertebrates was therefore conducted in order to assess the potential toxic effects on aquatic organisms following long term exposure. However, several technical difficulties were encountered during the performance of that study which finally prevented to obtain reliable results suitable for hazard assessment.
The Aquatic Chronic Category 4 Safety Net classification is applied.
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).
