Claims17
A controlled-viscosity polymeric hydrogel, comprising an aqueous solvent, a water-soluble synthetic polymeric component and an anti-cross-linking component, wherein the aqueous solvent has a pH ranging between 4 and 6 and that the anti-cross-linking component is hydroxytyrosol, oleuropein, tyrosol, oleocanthal and/or oleacein.
A method for making a controlled-viscosity polymeric hydrogel, comprising the following steps:
- rehydration of a synthetic polymeric component in aqueous solution with a pH ranging between 4 and 6;
- addition of a polyphenol additive to the solution, wherein the additive is selected from hydroxytyrosol, oleuropein, tyrosol, oleocanthal and/or oleacein;
- irradiation of the solution with an electromagnetic radiation having a frequency within a frequency spectrum of ß rays or of γ rays;
- polymerization of the hydrogel, limited by an antioxidant property of the additive.
