Viscosity

Viscosity is a principal parameter when any flow measurements of fluids, such as liquids, gels, creams and lotions are made. Gathering viscosity data on a material gives manufacturers the ability to predict how the material will behave in the real world. For example, if moisturizing cream does not have the correct viscosity, it can either be too difficult to squeeze out from the tube or dispense too much all at once. Knowing the viscosity of a material also affects how the production and transportation processes are designed. Viscosity measurements are often the most accurate and most reliable way to analyze some of the most important factors affecting product performance. As the viscosity of a solution, gel or lotion is dependent on the chemical composition, viscosity is a stability indicating analysis and is highly recommended as inclusion in stability monitoring.
