ABSTRACT:
The present invention provides freeze conditioning compositions for reducing moisture freezing problems found with moisture containing particulate solids, such as coal and ores and the like, comprising an alkylene polyol, such as ethylene glycol, and an effective amount of a cationic surface active material, preferably such cationics with at least one hydrophobic moiety. The preferred cationics are those with HLB of at least 11 or cationic compounds containing at least 18 total carbons, and those that are quaternary ammonium salts.
The present invention also provides methods of reducing such moisture freezing problems comprising applying to at least some of the surfaces of moisture-containing particulate solids a composition comprising an alkylene polyol and an effective amount of a cationic surface active material.
