Quantifying Shear Thinning Behavior on a Rotational Rheometer Using the Power Law Model
17 Dec 2014

In this application note, the shear thinning behavior of a skin lotion was evaluated by performing a table of shear rate test and analyzing the resultant curve using a power law model. The Power law model was found to give a good fit to the flow curve between 0.1 and 10s-1 yielding a value of 0.1735 for n and a value of 11.71 for k. This indicates that the material is highly shear thinning with a viscosity 1000 times greater than water at a shear rate of 1 s-1. Such a model has been shown to be useful for quantifying shear thinning behavior and also for comparing between products and formulations.
