Abstract
A method for treating particulate solids having surface moisture to reduce the cohesive strength of masses of such solids when frozen, said particulate solids being neither water soluble nor water swellable, said method consisting of spraying such solids with an effective amount of a hydrocarbon liquid solution of a nonionic surfactant having an HLB between 9.5 and 11.0.
Claims3
