Description of key information

One study conducted per OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)

Key value for chemical safety assessment

Log Kow (Log Pow):
2.72
at the temperature of:
30 °C

Additional information

The log Pow for HEMA-Phosphate (Reaction product of 2-hydroxyethyl methacrylate (HEMA) and polyphosphoric acid (PPA)) was determined from less than 1.0 to 2.72. The log Pow determined in the pH range relevant for the natural environment can be used to predict the potential for the test material to partition from water to organic matter in the environment. Since the log Powof the test material was estimated to be less than 2.7,the test material may be concluded to have low potential for bioaccumulation in aquatic organisms.
