A glycol- and/or glycerin-based 'universal' aircraft fluid (i.e., usable as any of Type I, II, III, or IV fluids), and having good resistance to degradation of viscosity and other critical properties caused by exposure to heat and/or shear, is disclosed. The fluid may optionally be prepared as a concentrate, and thereafter significantly diluted in the field for diverse uses. The improved performance is achieved by neutralizing a latex of a hydrophobe-containing, polymeric thickener with a base, preferably an alkali metal hydroxide, and preferably in combination with a weak base, such as a salt of a weak acid, and a surfactant which associates with the thickener.
