Description of key information

Additional information

TREGDMA has a good water solubility (3600 mg/L at 20°C), a low vapour pressure (0.077 Pa at 20°C) and a low log Kow of 2.3. The substance has a low potential for adsorption to soil (calculated log Koc 1.89 (Kow method) and 1.19 (MCI method)) and a low potential to volatilise from water to air (H = 9.26E-06Pa m³/mol at 25°C and 1013 hPa).

Results from a Mackay level III distribution modelling indicate that if TREGDMA is released into air, it mainly distributes to soil. A smaller amount remains in the air or partitions to water. If the substance is released into water, it mainly remains in water. The substance does not significantly partition to sediment.
