4C Polymer of low concern—low charge density (Act s 5)

For paragraph (b) of the definition of polymer of low concern in section 5 of the Act, a polymer has a low charge density if: (a) it is both: (i) not cationic; and (ii) not likely to become cationic in an aquatic environment that has a pH value greater than 4 and less than 9; or (b) it is a solid that is: (i) not soluble or dispersible in water; and (ii) to be used only in its solid phase; or (c) for a polymer that includes 1 or more cationic groups, the total combined functional group equivalent weight of any cationic group is at least 5 000.
