Fragrances:
Low Viscosity Fluids

Application Note

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.

1. What is thixotropic material?

Thixotropic materials are non-Newtonian fluids with high yield stress. This means that the samples can shear thin when enough shear stress has been applied. Over time, the materials will slowly return to their high viscosity state when shearing has ceased. 

2. Can RheoSense viscometers thixotropic materials?

Yes! VROC technology can handle thixotropic samples.
