Measuring Viscosity of Cosmetics with microVISC™

Easy & Robust Protocol

Skin care is an important part of personal healthcare. The epidermis is one of the body's largest organs and is first line of defense against pathogens, so maintaining and promoting healthy skin is vital for healthy life. 

Thixotropic materials are non-Newtonian fluids that have a high yield stress (material requires a large shear force to initiate flow) and will undergo shear thinning when enough shear stress has been applied. These materials will slowly return to their high viscosity state once shearing has ceased. This results in inconsistent data. 

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.
