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.

Abstract: Changes in the macroscopic nature of aqueous or colloidal formulations can lead to changes in the odor, appearance or feel of a product. Data presented in this article demonstrates ultrasound scanning to determine formulation shelf life and monitor product quality.
