Glycerol Ester of Partially Dimerized Rosin

During the last several decades, naturally derived masticatory substances have been displaced to a considerable degree by synthetic materials — for reasons of availability, economics, and. frequently, better control over purity. These developments essentially paralleled the development of Ihe synthetic rubbers for industrial uses. Some of the synthetic substances now used and listed in the "Food Chemicals Codex, published by the National Academy of Sciences (Washington. DC) include- butadiene-styrene 75/25 rubber butadiene-styrene 50/50 rubber glycerol ester of partially dimerized rosin glycerol ester of partially hydrogenated wood...

Glycerol Ester of Partially Dimerized Rosin occurs as a hard, pale, amber-colored resin (color M or paler as determined by ASTM Designation D 509) produced by the esterification of partially dimerized rosin with food-grade glycerin, and purified by steam stripping. It is soluble in acetone, but is insoluble in water.
