    • the total combined functional group equivalent weight of any cationic or potentially cationic groups is at least 5,000 g/mol
    • the chemical has a solubility in water of less than 0.1 mg/L and will only be used in its solid phase
    • the chemical is not dispersible in water and will only be used in its solid phase.
