What is DPM (Dipropylene Glycol Monomethyl Ether)?

DPM, or Dipropylene Glycol Monomethyl Ether, is a colorless, low-viscosity liquid with a mild alcohol-like odor. Chemically, it is a glycol ether with the formula C7H16O3, consisting of a dipropylene glycol backbone with a methoxy (-OCH3) functional group. Its main characteristics include high solvency, low volatility, excellent miscibility with water and organic solvents, and chemical stability. DPM is important because it acts as an effective solvent, coalescing agent, and formulation enhancer, making it widely used in industrial, commercial, and personal care applications.
