Abstract

See full text

The invention relates to nano-sized complexes formed by associating amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant. The amphiphilic polymer surfactants can form nano-sized assemblies in aqueous solution, serving as a nano dispersant preventing ACP and/or ACFP from aggregation, and as a nano carrier associating or attaching ACP and/or ACFP, stabilizing ACP and/or ACFP against the conversion to a crystalline form as well, thus maintaining calcium and phosphate/and fluoride ions in a bioavailable state for dental re-mineralization and prevention of dental caries, dental calculus and dental hyper-sensitivity. A method for the nano-sized complex preparation and compositions comprising the nano-sized complexes are also provided.
