Ester Gum is a glycerol ester of gum rosin with low odor and low acid value, especially applicable to chewing/bubble gum base, beverages and flavors. It is also used as a resin modifier for film formers, elastomers, and waxes, and in various adhesives, inks, and protective coating compositions where minimum odor is a requirement.

It is the slight yellow transparent solid, which is adducts of gum
rosin and maleic anhydride through the esterification by glycerol.
