Latest Patents
Djoerd Hoekstra holds a patent for a method of making free acids from polysaccharide salts. This invention describes a process where a free acid form of a polysaccharide is produced from its alkali-metal salt. In one example, free-form hyaluronic acid is produced by preparing a solution of an alkali-metal salt of hyaluronic acid, dispersing a strong acid into the solution, enclosing the dispersion within a semi-permeable membrane, dialyzing the dispersion in water, and harvesting the product from within the membrane. The strong acid can be hydrochloric acid, sulfuric acid, nitric acid, orthophosphoric acid, or oxalic acid. The semi-permeable membrane has a molecular weight cut-off large enough to pass the strong acid, and preferably much larger. This invention provides a simple and economical way to produce a product that is not commercially available.
