The present invention relates to a process for the preparation of pharmaceutical, injectable or ophthalmic grade hyaluronic acid, or a salt thereof, for use in the dermocosmetic or pharmaceutical field or in medical devices, which comprises dissolution of hyaluronic acid or a salt thereof in organic solvent, a heat cycle, and recovery of the product by precipitation and successive washes in organic solvents.

Process for the purification of hyaluronic acid salt, conducted in organic solvent

Disclosed is the use of glycosaminoglycan esters, whose alcohol groups are partly esterified with lipoic acid or with lipoic acid and formic acid, in hair care treatments.

Use of glycosaminoglycan lipoate esters in the trichology field

Disclosed is the use of glycosaminoglycan esters, whose alcohol groups are partly esterified with lipoic acid or with lipoic acid and formic acid, in hair are treatments.

Non-crosslinked derivatives of oligo/polysaccharides of formula 

Polysaccharides derivatised with citric acid

Disclosed are polysaccharides containing residues of glucosamine or galactosamine in the repetitive unit, characterized by the presence of esters on the hydroxyls or amides on the amine functions, with lipoic acid or with mixtures of lipoic acid and formic acid.

Polysaccharide derivatives of lipoic acid, and their preparation and use as skin cosmetics and medical devices

Acid polysaccharides characterized by the concomitant presence of partial esters with non-polysaccharide carboxylic acids and esters between the acid groups of the initial polysaccharide and the alcohol groups of the repetitive units, with the formation of crosslinking among the polysaccharide chains.
