Abstract: The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

Abstract: A new hydrogel made of crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Glycosaminoglycans that are crosslinked via an alkoxyboronate ester anion formed between a diol portion of a diol-functional moiety grafted to a first glycosaminoglycan and a boronate hemiester grafted to a second glycosaminoglycan.

Abstract: A new hydrogel made of double crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Double crosslinked glycosaminoglycans, one linkage via two ether bonds with a hydroxyl group of each of two glycosaminoglycans and another linkage via an alkoxyboronate ester anion formed between a boronate hemiester grafted to one of the glycosaminoglycans and a diol function of to the other glycosaminoglycan. The diol function may be a backbone diol function or a diol portion of a diol functional moiety grafted the other glycosaminoglycan.

Abstract: Enantiomers of butanediol diglycidyl ether (BDDE) are present in an enantiomerically enriched enantioenriched mixture of BDDE stereisomers or in an enantiomerically pure BDDE. Enantiomerically enriched or pure BDDE is useful as a cross-linking agent, such as in the preparation of a cross-linked hyaluronic acid product.
