Abstract
A water-soluble diammonium compound, such as N-methyl-N-(2-hydroxyethyl)-N-tallowalkyl-N'-methyl-N'-bis(2-hydroxyethyl) -propylene-diammonium methosulfate, is homogeneously and finely dispersed in a spray-dried detergent bead or granule. The spray-dried bead is blended with a clay mineral fabric softener. The final composition exhibits antistatic action even at low levels (e.g. less than 2%) of the antistat without adversely effecting softening, cleaning or whitening. In a typical formulation, the spray-dried beads include linear alkyl benzene sulfonate or other anionic surfactant, an inorganic polyphosphate and/or other inorganic and/or organic detergent builder salt, diammonium compound antistatic agent, and other heat stable and pH insensitive detergent additives and fillers. In addition to a smectite clay fabric softener, other post-added ingredients typically include a nonionic surfactant, enzyme, perfume, bleach, and other detergent additives which may be pH sensitive, heat sensitive, water-insoluble, or reactive with one or more of the components of the spray-dried beads.
