Viscosity data for different colognes were obtained using microVISC™. Over the shear rates explored, 200 to 5,100 1/s, the colognes exhibited Newtonian behavior.
The viscosity of these colognes was found to be between 1.72 and 2.12 mPa-s. The primary ingredient was alcohol, but there were still up to a 20 % difference in the viscosity between the highest and lowest viscosity samples.
This result shows that formulations with similar base ingredients can still have a wide range of viscosities based on the other components of the formulation.
