Shellac-glycerol reaction intermediates were prepared. Tablets were prepared using solutions of these esters as anhydrous binding agents (3.5) and evaluated. The esters exhibited excellent binding properties, imparting hardness to the tablets. The t50 for shellac and SG-33 (acid value 33) is 30 and 28 min. respectively. For other esters t50 lies between 38 to 57 min.
