Abstract

Viscometers, USDA consistometers, and Bostwick consistometers are often used to evaluate thickness and flow of gel based personal care products. These methods do not always provide results that are both differentiating and repeatable. Particulates in the sample and other inclusions like air bubbles can drastically influence the results. This application study presents a back extrusion testing method using the Stable Micro Systems TA.XTPlus Texture Analyzer that is nominally affected by particulates or other inclusions, uses small amounts of sample, and provides differentiating and repeatable results.
