Abstract
A neutral salt consisting of a polyaminosaccharide cation and an anion, as well as a procedure for the preparation of the neutral salt and uses thereof as a biomaterial and as an ingredient in pharmaceutical compositions are disclosed. Indeed, said neutral salt has surprisingly exhibited high water-solubility and high purity, the preparation procedure having minimised the content of high-risk contaminants in the final product and reduced reaction and purification times.
