Ice release agents consisting of pseudo-plastic compositions of crosslinked polyacrylic acid in water-polyglycol mixture

Ice release composition which is effective on non-horizontal substrate surfaces comprising:

• a. a mixture of an alkylene glycol having two to three carbon atoms and water in a glycol:water weight ratio of about 20:80 to about 90:10.
• b. about 0.05 to about 1.0 parts of crosslinked polyacrylic acid per 100 parts of (a);
• c. sufficient base to neutralize the crosslinked polyacrylic acid, said base selected from the class consisting of alkali metal hydroxides, ammonium hydroxide, alkyl amines having 4 to 12 carbon atoms, alkanolamines having 2 to 12 carbon atoms and morpholine;
• and
• d. about 50 to about 100 parts of an alkanol, having one to three carbon atoms, per 100 parts of the combination of (a), (b) and (c).
