Quantifying Viscosity Recovery Following Extrusion or Spraying Using Thixotropy Assessment on a Rotational Rheometer
13 Jan 2015

In this application note, a three step shear rate test was performed on a toothpaste and body lotion to evaluate the extent of viscosity recovery following extrusion from a tube and bottle respectively. The toothpaste was shown to be highly thixotropic taking 6 minutes to recover 70% of its original viscosity. The body lotion attained the same degree of recovery in just 7 seconds and can be considered non-thixotropic in comparison.
