Oct 21st, 2008
Malcolm Povey, Procter Department of Food Science and Lyn S. Daintree, PhD, Institute of Particle Science & Engineering

Ultrasound scanning is a highly promising new technique for product characterization and stability determination of colloidal and aqueous-based formulations. The stability of colloidal and fluid/particle dispersions is of increasing importance to the cosmetic and personal care industry where differences in raw materials can affect the batch-to-batch quality of products. Additionally, product developers in the industry need tools to predict formulation stability to reduce development time.
