Residual solvent for Carbopol 1342 NF: Benzene
Recommended non-benzene substitute products for Carbopol 1342 NF: Pemulen™ TR-1 NF and TR-2 NF polymers
Carbopol® 1342 NF polymer is highly effective in formulating pourable products containing suspended ingredients and stabilizing emulsions. Carbopol 1342 NF polymer contains a long chain alkyl acrylate, a lipophilic modification to its chemical backbone.
Lubrizol's benzene polymerized polymers do not meet the European Pharmacopeial "Carbomers" monograph because the residual benzene levels exceed the 2 ppm limit stipulated in the monograph.
