Glycerol Formal is unique among acetal solvents in that it is a high-boiling mixture of two isomers. It is thermally stable and stable to mild acid-base conditions, and has broad use in aqueous formulations. Glycerol Formal provides an environmentally-friendly alternative to standard solvents. Its water solubility, high solvency, and slow evaporation rate make it an ideal emulsifier and solubilizer for the formulation of stable agricultural chemicals and other water based functional fluids.
