DESCRIPTION
Glycerol Ester of Gum Rosin occurs as a hard, pale amber-colored resin (color N or paler as determined by ASTM Designation D 509) produced by the esterification of pale gum rosin with food-grade glycerin. When intended for use in chewing gum base, the product is usually purified by steam stripping, but when intended for use in adjusting the density of citrus oils for beverages, it is purified by countercurrent steam distillation. It is soluble in acetone and in toluene, but is insoluble in water.
