Experimental investigation of rheological properties of niosomal dispersions

In this work, the rheological properties of niosomal dispersions of various concentrations in the temperature range of 30–60$^\circ$C is investigated. The viscosity coefficient and the values of the activation energy were determined experimentally. It is found that the flow of niosomal dispersions exhibits the properties of Newtonian fluids in the studied range of temperatures and shear rates. Conditions were determined for obtaining stable homogeneous niosomal dispersions with an average vesicle size of 80–150 nm.
