Is your polymer cationic or likely to become cationic in an aquatic environment that has a pH between 4 and 9?

Is your polymer a solid that is not soluble (less than 0.1mg/L) or dispersible in water and is it to be used only in its solid phase?

For your polymer, is the combined FGEW of any cationic groups or
potentially cationic groups greater than or equal to 5,000 g/mol?

Does your polymer have any known hazard classification?

Does your polymer have any GHS classifications not on the following list:
