Application

Calcium chloride dihydrate has been used for synthesis of chemical hydrogels based on telechelic Poly (vinyl alcohol) (PVA). It has also been used for investigating the morphology of polystyrene-based emulsion-templated (PolyHIPE) materials.

Biochem/physiol Actions

Calcium chloride act as precipitants during protein crystallization process. It also enhances the competence of Escherichia coli cells as well as strengthened β-lactoglobulin gels by forming crossbridges.
