Abstract

Dusting of powders is prevented by wetting the powder with an emulsion comprised of an aqs. continuous phase and a disperse phase comprised of a low volatility org. liq. and suitable emulsifiers. The process is esp. useful in collieries; the evapn. of the water is retarded, thus prolonging the anti-dusting effect.
