A process for the extraction of collagen from collagen-containing matter, wherein the process comprises; incubating the collagen-containing matter in an acidic solution to form an incubant, then diafiltrating the incubant to substantially purify solubilised collagen within the incubant, thereby forming a retentate, then separating the soluble and insoluble matter of the retentate to remove the remaining insoluble matter, wherein the soluble matter is a substantially pure collagen solution.

A dried implant composition for preparing an injectable aqueous implant formulation that is extrudable through a tapering system and a gauge 18 cannula, including a mixture of nanocrystalline hydroxyapatite particles derived from natural bone having a size of 50 to 200 μm and fragments of naturally crosslinked fibrous collagen material that pass through a 0.5 mm sieve; an injectable aqueous implant formulation, wherein the injectable aqueous implant formulation is obtainable by hydration and homogeneous mixing; a process for preparing the injectable aqueous implant formulation; and a kit for preparing the injectable aqueous implant formulation.
