The water-binding properties of a polymer greatly influence its structure, stability and macroscopic properties.
In formulations, water-binding acts as a reservoir for water that, upon application, enables the formation of a protective and hydrating film.
A high water-binding capacity also facilitates and enhances the loading of actives. The water-binding capacity and characteristics of cross-linked HA gel, HA and other natural polymers were thus measured, using differential
scanning calorimetry (DSC) thermograms (transition temperature heating curves).
