New free-radical scavenger containing viscoelastic composition, methods of use and package

摘要

The present invention is directed to a viscoelastic composition comprising an aqueous solution having a minimum of about 0.01% w/v and a maximum of about 20% w/v of a viscoelastic polymer based upon the total volume of the viscoelastic composition. Typically, the viscoelastic composition further contains tris[hydroxymethyl]aminomethane and a polyol (for example sorbitol). The present invention also includes methods of use of the new viscoelastic composition and a packaging device.
