Polymers are exempt from registration according to EU Regulation 1907/2006/EC (see [3]), REACH.
Monomer substance(s) and any other substance(s) in the form of monomeric units and chemically bound
substance(s) may have to be REACH registered according to Article 6 of EU Regulation 1907/2006/EC.

6 Chemical properties
6.1 General
Anionic and non-ionic polyacrylamides are non-hazardous materials and not intrinsically reactive.
However, in common with many other organic compounds, a strong exothermic reaction will occur if
they are brought into contact in the dry state with a strong acid or strong oxidizing agent.
NOTE In dilute solution there can be a reaction with, or destruction by, some of the disinfection and oxidizing
agents used in water treatment.
6.2 Purity criteria
6.2.1 General
This document specifies the minimum purity requirements for anionic and non-ionic polyacrylamides
used for the treatment of water intended for human consumption. Limits are given for impurities
commonly present in the product. Depending on the raw material and the manufacturing process other
impurities may be present and, if so, this shall be notified to the user and when necessary to relevant
authorities.
Limits have been given for impurities and chemical parameters where these are likely to be present in
significant quantities from the current production process and raw materials. If the production process
or raw materials lead to signifi
