Disclosed are adducts of boric acid and chitosan wherein the amino groups of the D-glucosamine units are bonded to residues of polyol or alditol oligosaccharides, the molar ratio between boric acid and the repeating chitosan unit ranging between 0.001 and 4.

Soluble adducts of boric acid or derivatives and precursors thereof with chitosan oligosaccharide derivatives

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 acid polysaccharides characterized by the concomitant presence of alcohol groups esterified with butyric and formic acids.

Mixed butyric-formic esters of acid polysaccharides, and their preparation and use as skin cosmetics

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.

Derivatives of acid polysaccharides

A new class of polysaccharides containing carboxylic groups selectively substituted with halogens on the carbon atom on position 6 of the glicopyranosidic residue and the procedure to obtain these derivatives is therein described. The procedure entails the halogenation of carboxylated polysaccharides with alkyl aryl sulfonyl-halides in organic solvent. The products of this invention can be used as substrates in synthesis where the reactive site is the carbon that binds the halogen. Moreover, they can be used in the medical-diagnostic field.
