Many products in every day use, such as foodstuffs, pharmaceutical medicines and creams, drinks, paints, inks and personal care products, are suspensions. This whitepaper, part of Malvern Instruments’ popular ‘Ten Ways to…’ series, explores how the properties of particles in a suspension can be manipulated to control rheology and, consequently, product performance. The impact of particle size and size distribution, particle shape, particle loading and zeta potential are all discussed, providing a comprehensive guide to the strategies that can be deployed to tailor suspension properties to meet formulation goals.
The rheology of a suspension can directly influence the consumer appeal of a product by affecting for example, stability, texture/mouth feel, processability and ease of use. Varying the properties of particles in a suspension is one way in which a formulator can control the rheological profile of a dispersed system to deliver products with enhanced performance and high commercial value. In this paper, Malvern rheology experts survey the interacting effects of particle properties to provide information that supports a knowledge-led approach to formulation.
