Characterization of Physicochemical Properties of Nanoemulsions: Appearance, Stability, and Rheology

Abstract The physicochemical properties of nanoemulsions play an important role in determining their functional attributes and suitability for application in commercial products, such as food, supplements, pharmaceutical, or personal care products. In particular, the optical properties (appearance), rheology (texture), and stability (shelf life) of nanoemulsion-based products strongly impact their ability to be used in specific applications. This chapter provides an overview of the different analytical tools available to characterize the optical, stability, and rheological properties of nanoemulsions.
