Description of key information
Polyaldo 2-1-IS (CAS 73296-86-3) is considered to be readily biodegradable according to the OECD criteria. The substance is thus expected to be rapidly degraded by microorganisms in aquatic and terrestrial environments.
Based on its physico-chemical properties such as low water solubility (3.854 E-11 – 0.03 mg/L), low volatilization potential (vapour pressure: 3E-08 Pa) and high log Koc (2.23 – 7.63), sediment and soil are expected to be the main targets for the environmental distribution of Polyaldo 2-1-IS (CAS 73296-86-3). However, due to its ready biodegradability, the substance is not expected to persist in these compartments.
Additional information
Polyaldo 2-1-IS (CAS 73296-86-3) is a UVCB substance, which is characterized by a low water solubility (<0.03 mg/L), low vapour pressure (3.0E-8 Pa at 20.0 °C) and a high estimated log Koc (3.33 - 6.85, QSAR) as well as a high n-octanol-water partition coefficient (> 6.5, OECD 117), suggesting high lipophilicity. The substance is readily biodegradable by microorganisms in water (60.4% degraded after 28 d, 10 d-window fulfilled, OECD 310). Based on the low vapour pressure, evaporation to the atmosphere and the subsequent transport and dispersion through the atmospheric compartment is not expected. The ready biodegradability of the test substance indicates that the substance will be eliminated in both aquatic and terrestrial environments. Consequently, no significant accumulation in sediment and soil is expected despite its high log Koc indicating low mobility and high sorption potential. Though the log Kow suggests the substance will accumulate in fat tissue, its low water solubility is expected to preclude significant uptake by aquatic organisms in surface waters.
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.
