A process for preparing a detergent composition is provided. The process involves: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein the ratio of the surfactant paste to the dry detergent material is from about 1:10 to about 10:1; and (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates. The dry detergent material contains a builder which is a selected crystalline calcium carbonate material substantially having a rhombohedral crystalline structure with {1,0,-1,1} crystallographic indices.

A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with an encapsulating material such as a carbohydrate is provided. The crystalline calcium carbonate can be calcite and the encapsulating material can be sucrose. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e. g. less than 10 m. sup. 2 /g surface areas).

A multi-step process for making a granular detergent composition. The processing steps include adding to a first fluid bed dryer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a mixer to form a fourth feed stream, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the mixer. The fourth feed stream is added to a second fluid bed dryer to form the granular detergent composition. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.

A process is provided for producing high-active detergent agglomerates through multi-stage surfactant paste injection. According to the process, starting detergent materials are mixed with an initial amount of surfactant paste and then allowed to age for a specified period of time. Following the initial paste injection and aging period, additional amounts of surfactant paste are injected incrementally to make a final detergent agglomerate having at least about 45% by weight of surfactant.

The present invention provides a process which produces high density detergent compositions especially suitable for commercialization as a compact detergent product. The process can be easily retrofitted into existing spray drying detergent-making production plants in that it utilizes existing equipment so as to economize the transition from "tower" based to "non-tower" based detergent manufacturing plants. The process comprises the steps of: (a) agglomerating starting detergent ingredients in a mixer/densifier such that detergent agglomerates having a density of at least 650 g/l are formed; (b) conditioning the agglomerates in a spray-drying tower so as to enhance the free flowability of the detergent agglomerates: and (c) admixing adjunct detergent ingredients in the detergent agglomerates, thereby producing the high density granular detergent composition.

A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process comprises the steps of: (a) charging a viscous surfactant paste into a mixer/densifier wherein the surfactant paste has a viscosity of from about 5,000 cps to about 100,000 cps and contains at least about 5% water; (b) adding from about 1% to about 70% of an anhydrous material into the surfactant paste just prior to entrance into the mixer/densifier to absorb at least a minor amount of the water from the surfactant paste; and (c) agglomerating the surfactant paste and the anhydrous material in the mixer/densifier so as to form detergent agglomerates having a density of at least about 650 g/l. The detergent agglomerates have high surfactant levels.

A process for preparing a detergent particle having a coating layer of a water-soluble material is provided. The process comprises providing a particle core of a detergent active material and the particle core is then at least partially covered by a particle coating layer of a water soluble coating material including double salt combinations of alkali metal carbonates and sulfates that reduces the surface area of the particle.

A detergent composition which has improved solubility or dissolution in laundering solutions, especially in solutions kept at cold temperatures (i. e. , less than about 30° C. ), is provided. The granular detergent composition is aesthetically pleasing to consumers and has improved flowability. The granular detergent composition has a homogeneity number of greater than 1 wherein the homogeneity number is defined by the equation HN=X/X. A process for producing the detergent is also provided.

A process for preparing coated detergent granules in a fluidized bed. The fluidized bed is operated at a flux number of at least about 4 and at a Stokes Number of 10 to about 1000 using a coating solution or slurry having a viscosity from about 300 to about 100,000 centipoise, measured at 60° C. Upon drying, the resultant detergent particles have improved appearance and flow properties and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.

A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process includes the steps of: (a) agglomerating an aqueous surfactant paste and dry detergent material in a mixer/densifier so as to form detergent agglomerates having a density of at least about 650 g/l; and (b) inputting air into the mixer/densifier while agglomerating the aqueous surfactant paste and the dry detergent material, wherein the air has a relative humidity below the equilibrium relative humidity of the detergent agglomerates such that at least a minor amount of water from the surfactant paste is absorbed by the air.
