ABSTRACT:
Ternary mixtures, particularly suitable for removing oily substances having both an hyrogenated and fluorinated or mixed basis, essentially consisting of: (a) water; (b) terbutanol; (c) a fluoropolyoxyalkylene having hydrogenated end groups and/or hydrogenated repetitive units. Such mixtures have high flash point, are non toxic and with null depleting potential of the ozone and show a ternary diagram characterized by a wide monophasic zone, wherein the three components form limpid and stable solutions.
