Product Description

Hydrolyzed Polyvinyl Alcohol USP Grade For Eyedrop


During the hydrolysis process an alkaline catalyst is used in the methanol solvent to convert the acetate groups of the polyvinyl acetate to hydroxyl groups to generate a reaction to form POVAL. This process controls the amount of hydroxyl groups (called the degree of hydrolysis). The solubility and membrane water resistance of POVAL vary greatly depending on the degree of hydrolysis.
