Carbopol® 1342 NF Polymer

Suitable applications: Topical
Residual solvent: Benzene
Recommended non-benzene substitute products: 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.  This gives the polymer slightly increased resistance to dissolved ions, making it uniquely suited for use in aqueous systems containing dissolved salts. The lipophilic group gives Carbopol 1342 NF polymer a compatibility advantage over other Carbopol^® polymers in thickening and imparting yield value to ionic systems.

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.
