** Please note: Due to regulatory restrictions on the use of benzene in pharmaceutical formulations, Lubrizol recommends the use of carbomers polymerized in toxicologically preferred solvents for all new drug development projects. A list of substitute products for benzene grade Carbopol® polymers is included below. Ingredient substitutions in existing pharmaceutical formulations should be verified to confirm compliance with key performance properties and regulatory requirements. Please contact your regional Lubrizol sales representative or distributor if assistance is needed with polymer selection.
