Work out if your polymer is a polymer of low concern (PLC)

If you are unsure if your polymer is a polymer of low concern (PLC), use this decision tool to find out.

What is your chemical's name or CAS number? (optional)

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?
