Abstract
A dust suppressant composition comprising an aqueous solution of a dust suppressant comprising an ethoxylated alcohol and an ethoxylated alkyl phenol. The ethoxylated alcohol and ethoxylated alkyl phenol are preferably included in a weight ratio of about 1:3 to 3:1 and the dust suppressant is included in the aqueous solution in an amount of about 0.01 to about 1.0 weight percent. The composition is adapted for enhancing the settling of air-borne dust by spraying the composition in the dusty air.
