Abstract:
The present invention relates to a process for depleting epoxide species in epoxy-crosslinked polysaccharide gel compositions. In addition, the present invention relates to crosslinked polysaccharide gel compositions made by said process and their use in cosmetic and therapeutic applications.

Claim (Index 1):
A process for depleting epoxide species in a crosslinked polysaccharide gel composition, the process comprising:\n (a) providing a crosslinked polysaccharide gel composition, the polysaccharide being crosslinked with a bifunctional or multifunctional epoxide crosslinker, wherein said composition comprises epoxide species resulting from the polysaccharide crosslinking process, (b) subjecting the crosslinked polysaccharide gel composition to one, two, three or four of (i) to (iv):\n (i) exposing the crosslinked polysaccharide gel composition to heat to effect thermal hydrolysis of epoxide functional groups of the epoxide species, \n (ii) contacting the crosslinked polysaccharide gel composition directly or indirectly with a hydrolyzing agent to effect hydrolysis of epoxide functional groups of the epoxide species, \n (iii) contacting the crosslinked polysaccharide gel composition directly or indirectly with a nucleophilic agent to effect ring-opening of epoxide functional groups of the epoxide species, and \n (iv) contacting the crosslinked polysaccharide gel composition directly or indirectly with an adsorbing agent, \n (c) dialyzing the crosslinked gel composition either concomitantly with and/or after said one or more (i) to (iv) to obtain a crosslinked polysaccharide gel composition depleted in epoxide species.
