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 overall environmental fate profile indicates that stearamide is not to be persistence in the environment.

Due to the low vapour pressure of stearamide, a Henry’s Law Constant of 0.10 Pa x m³/Mole at 25 °C and the rapid half-life in air calculated according to AOPWIN v1.92 (2010) to be 0.5 days, it is concluded that stearamide will not accumulate in air and will not be transported through the vapour phase into other environmental compartments in relevant amounts. Thus, air is not a likely route of environmental contamination and no accumulation and subsequent deposition of stearamide is to be expected.

Binding potential to the solid soil phase (e. g. clay) is expected due to the Koc of 4.6. Environmental distribution was calculated using the Mackay Level 1 model. Due to the results of the Mackay LEVEL 1 calculation, over time the substance will, if released to the environment preferentially distribute into the compartments soil (44 %) and sediment (44 %). But an exposure of sediment is unlikely as the substance is readily biodegradable and insoluble in water. Therefore, and as predicted by EPISuite, the substance will tend to remain in the STP facilities (Total removal of 94% (estimation)). Thus, only small amounts will be released into the environment and a relevant exposure to soil and sediment is not expected.
