1 Pemulen™ Polymers (Pemulen TR-1 NF and TR-2 NF). All other products noted in the table belong to the Carbopol® polymer product family.
2 Traditional polymers are synthesized in benzene. The Carbomers Monograph in the European Pharmacopeia stipulates that benzene is limited to 2 ppm.
3 Prolonged exposure to high shear should be avoided for all carbomers.
