Abstract

A process for crosslinking a polymer using resonant acoustic mixing is disclosed herein. The process comprises adding an aqueous solution comprising a dissolved base to the polymer to produce a substantially homogenous gel; adding a crosslinking agent to the substantially homogeneous gel to produce a mixture; and subjecting the mixture to resonant acoustic mixing conditions sufficient to effect crosslinking of the polymer, wherein the resonant acoustic mixing conditions comprise a forcing energy ranging between about 20 g to about 100 g. Also disclosed are cosmetic, therapeutic and/or prophylactic applications of products comprising a crosslinked polymer produced by resonant acoustic mixing.

IPC Classes  ?

• C08J 3/24 - Crosslinking, e.g. vulcanising, of macromolecules
• A61K 31/738 - Cross-linked polysaccharides
• A61L 27/20 - Polysaccharides
