This invention is directed to the reduction of the strength of ice in association with solid particulate materials, such as, for example, coal, by applying to the solid particulate material, prior to exposure to water freezing conditions, a composition comprising a mixture of a glycol derived from ethylene oxide and containing from 1 to 4 oxyethylene units and an alkyl and/or an aryl ether of a glycol derived from ethylene oxide and/or propylene oxide and containing from 1 to 9 oxyalkylene units.

Method and composition for reducing the strength of ice

This invention is directed to a method for reducing the strength of adhesion of solid particulate materials to metal surfaces as occurs under water freezing conditions by coating the metal surface with a mixture comprising a hydrocarbon liquid which has a solidification or pour point not greater than 0.degree. F. and a saturated or unsaturated fatty acid having from about 10 to about 18 carbon atoms.
