Consumer care products are complex industrial fluids that are highly time dependent.

Successful cosmetics and personal care products need the right rheological properties. Since many products are non-Newtonian liquids, the industry is dependent on complex flow measurements. The measurements are required to determine how a product feels when used (e.g. skin sensation), how it behaves (e.g. pumping performance) and how it changes over time (e.g. stability). The measurements are also needed to choose/change/modify ingredients, to decide manufacturing conditions and to troubleshoot product failures. Most manufacturers have several parallel continuous production lines and there is an unmet need to accurately measure these complex flows in-line and in real-time. Currently, measurements are performed using slow off-line rheometers or inaccurate in-line flow meters/viscometers.
