Pharmaceutical formulators require precise rheological control for topical applications. Clariant's Motusflex polymers, manufactured under GMP conditions, deliver exceptional batch consistency with defined impurity profiles. These pre-neutralized, synthetic cross-linked polymers simplify processing while providing scalability from R&D to production. Our rheology modifiers achieve targeted viscosity in both high and low viscous formulations, maintaining stability in high-salt environments while delivering superior sensorial properties through cold-processing compatibility.
