Anwendungen & Verwendung
Occurrence
Has apparently not been reported to occur in nature.
Verwenden
Diethylene glycol monomethyl ether is used in textile dye pastes, in lacquer industrial for thinners and quick drying varnishes; solvent for wood stains, hydraulic brake fluid diluent, and as a coupling agent for miscible organic aqueous systems. Diethylene glycol monoethyl ether is used as a solvent in lacquer, varnishes, and enamels. It is also used in cosmetic products and dermatological preparations and as a solvent in some medicine products. It enhances the percutaneous absorption through the skin and mucosal barriers. It is used in some drugs to enhance absorption. Diethylene glycol monobutyl ether is used as a solvent in paints, dyes, inks detergents, and cleaners. Used in the same way as 2-ethoxyethanol where a solvent with a higher boiling point is required.
Herstellung & Synthese
