Abstract
Abstract A nonagglomerating, nonsegregating premix for animal feeds comprising an intimate mixture of an active ingredient and a carrier. The active ingredient has dispersed upon the particles thereof a quantity of a first emulsifier equivalent to 0.1 to 1.0 percent by weight of the active ingredient, the emulsifier having an HLB value of at least 12. The carrier has dispersed upon the particles thereof a quantity of a second emulsifier equivalent to 0.1 to 1.0 percent by weight of the carrier and having an HLB value of 8 or less. The ratio of active ingredient to carrier in the premix can vary from 1 to 9 parts by weight to 4 to 1 parts by weight. Such premixes when blended with feed produce little if any electrostatic charge.
