Abstract
An improved resorbable body and tissue compatible wax useful for the mechanical coagulation of blood on bones is produced by the reaction of, for example, lactic or glycolic acids with glycerol. The reaction mixture is then purified by forming a solvent suspension and washing with isopropanol to produce a purified wax essentially free of the hydroxycarboxic acid impurity, say, less than 0.1%.
