| Benefits / Claims | Highly efficient thickeners, at low usage levels. Polymer swells in water and neutralisation may be required to achieve the desired viscosity (max typically at pH=6). Thixotropic, possessing shear thinning properties. Improved bioavailability of active ingredients due to carbomer bioadhesive properties. |
