Dipropylene Glycol Monomethyl Ether (DPM) (CAS NO : 34590-94-8)

DPM (Dipropylene Glycol Monomethyl Ether) (Glycol ether (–OH)) is a solvent known for its free hydroxyl group, which makes it more water-attracting (hydrophilic) and chemically reactive. This gives it an edge in applications that require good solubility and faster reactivity, especially in water-based systems. On the other hand, DPMA (Dipropylene Glycol Monomethyl Ether Acetate) (Glycol ether acetate (ester) has a similar base structure but with an important difference - its hydroxyl group is acetylated, turning it into an ester. This change makes DPMA more hydrophobic and less reactive, which also slows down its evaporation rate. Because of these differences, DPM and DPMA are used in different ways depending on the performance needs of the formulation.
