Back to Basics: Viscosity Fundamentals

Key Words: Face lotion, hand lotion, cream, viscosity, shear thinning, cleaning, high shear, non-Newtonian fluid, protocol, thixotropy
Goal: Cosmetic lotions are often non-Newtonian fluids with yield stresses and thixotropic structure. These properties are vital for their function as self-care products, but also make their rheological properties difficult to characterize. In particular, data collection can be time consuming and instrument cleaning can be challenging. This application note will share an easy-to-implement protocol to precisely measure complex cosmetic formulations using VROC technology.

If you are not performing high shear viscosity testing on your proteins, then you are not fully characterizing your samples.

The cannabis industry has been growing as regulations continue to change and the demand for cannabis infused products are increasing. We have been working with many cannabis companies who are working towards a more scientific approach when formulating their cannabis products (learn why it is essential).

I recently had a customer who asked how VROC® technology measures viscosity compared to a rheometer that measures shear stress and also control shear rate. From the controls, the rheometer will then calculate viscosity. Similar to the rheometer, VROC® powered viscometers will measure the pressure drop to measure shear stress and use flow rates to control the flow. Essentially the ideas are parallel in the fact that VROC® measures the pressure drop and rheometers will measure torque so you will not need to readjust your expectations when working with VROC® technology.

At the 2020 Peptalk Conference that took place in San Diego, our Principal Scientist, Dr. Stacey Elliott, gave a talk regarding a thorough investigation of antibody therapeutics using viscosity results.

Working with various CROs and CDMOs, we've come to the question that many companies find themselves asking, "what is the cost of providing the wrong viscosity values to my customers and worse, having them submit the values for FDA approval?"
