Zeta Potential Characterisation

Zeta potential characterisation measures colloidal particle electrical charge predicting formulation stability. Electrokinetic sonic amplitude quantitates charge. Surface charge influences particle aggregation. pH and ionic strength modulate potential. Optimization prevents unwanted precipitation.

Formulation stability assessment employs zeta potential. Shelf-life prediction incorporates charge effects. Regulatory submissions justify formulation design. Post-approval monitoring confirms stability. Emerging measurements improve assessment accuracy.
