Which instrument to choose for shampoos & lotions?
Shampoos and lotions need to flow easily yet retain sufficient thickness. viscosity analysis and temperature profiling are important QC tools to use.
For personal care products we are recommending:
RST-CPS Touch Rheometer– small sample volume and rapid temperature control
CT3 Texture Analyzer– this fantastic instrument can extrude the semi-solid gel of cream or ointment in a controlled manner, revealing the yield stress and flow characteristics of the product.
