Abstract
The present invention relates to a preserved, yet non-cytotoxic alginate based hydrating gel system for the purpose of treating wounds that need moisture. Sodium carboxymethylcellulose and an alginate polymer blend impart sufficient viscosity to an aqueous solution to provide moisture to the wound. The blend reduces the cytotoxicity of a combination of preservatives incorporated into the system. More specifically, the invention relates to a wound hydrating gel comprising a) a hydrocolloid mixture of carboxymethylcellulose and sodium/calcium alginate, and b) a preservative system. This invention further relates to methods of preparing and using the wound hydrating gel.
