Abstract:
A method for producing a fabric cleaning composition, comprising the steps of:(a) introducing into a mixing vessel at least one particulate material comprising an inorganic salt carrier and a flow agent, wherein said inorganic salt carrier is selected from the group consisting of sodium sulfate, sodium chloride, sodium carbonate, sodium bicarbonate, sodium borate, sodium citrate, sodium tripolyphosphate, sodium nitrate and mixtures thereof; and said flow agent is selected from the group consisting of silica and metal oxides; (b) introducing at least one liquid active material, selected from the group consisting of fragrances, surfactants, solvents, pesticides, and mixtures thereof, into the mixing vessel to form a mixture; (c) blending the mixture for a first predetermined period of time; (d) chopping the mixture for at least a portion of the first predetermined period of time; and (e) thereafter blending the mixture without chopping for a second predetermined period of time, so as to agglomerate any fins produced during said chopping, whereby at least 95% of the resulting composition comprises particulates having a particle size greater than 0.105 millimeters and the composition comprises at least 80 weight percent inorganic salt carrier, from 1 to 10 weight percent flow agent, and from 0.1 to 15 weight percent liquid active agent.
