The physicochemical properties of the high intensity sweetener, sucralose, (1,6‐dichloro‐1,6‐dideoxy‐β‐D‐fructofuranosyl 4‐chloro‐4‐deoxy‐α‐D‐galactopyranoside) were determined. A high solubility in water (28.3g/100 mL at 20°C) in combination with Newtonian viscosity characteristics, a negligible lowering of surface tension, and no pH effects demonstrated that sucralose was particularly suitable for use in liquid products. The refractive index of aqueous solutions was linear with respect to concentration confirming the usefulness of this technique for determining solution concentrations. A low octanol‐water partition coefficient confirmed that sucralose was poorly soluble in lipids and was, therefore, likely to behave in a similar fashion to sugar in multiphase systems.
