  • Abstract:


    Carbomers are cross-linked polyacrylic acid polymers used as gelling agents in topical drug products. Gel formation occurs in two stages: (i) dispersion and hydration and (ii) neutralization of -COOH groups by a basic compound. In order to solubilize lipophilic drugs, non-polar solvents like ethanol are added to gels. The compatibility
