Dipropylene glycol monomethyl ether is widely used in the coatings and resins industry as a coupling agent and active solvent; in cleaning agents and personal care products (including degreasers, paint strippers, and metal cleaners); in cosmetic formulations as a coupling agent and skin-conditioning agent; in fragrances as a fixative; and in inks and dyes, serving as a primary solvent and coupling agent for solvent-based screen printing inks. In textile printing and dyeing, it acts as a co-solvent for vat dyes and enhances the solubility of disperse dyes.
