The invention provides methods for making such formulations and methods of using such formulations. The invention further provides methods of reducing polysorbate degradation, methods of reducing the amount of visible and sub-visible particles in an aqueous formulation, and methods of disaggregating polysorbate degradation products comprising adding a cyclodextrin to a formula comprising polysorbate and a polypeptide. The invention also provides aqueous formulations comprising a polypeptide, a polysorbate, and a cyclodextrin with reduced polysorbate degradation.
