This poster, by Dr. Stuart Porter and Lana Terzian of ISP Pharmaceuticals, provides an excellent example of using design of experiments for texture analysis experiments. This experiment attempts to understand interactions between common film coating ingredients. The coating formulations were evaluated for tensile strength, elasticity, adhesion to tablet surfaces, viscosity and contrast ratio. The free film properties (tensile strength, elasticity and toughness) were evaluated using a TA.XTPlus Texture Analyzer.
