An enhanced efficacy aluminum only salt active. The method for making such active comprises the steps of (a) providing an aqueous solution of an aluminum salt having a Band III polymer concentration of at least about 20%; (b) adding to the aqueous solution of step (a) an aqueous solution of a monomeric aluminum salt to form a mixture; and (c) rapidly drying the mixture to form a product powder. The active comprises an aluminum only salt having a Band III polymer concentration of at least about 20%, an aluminum to anion ratio of from about 1.1:1 to about 1.8:1 and a level of monomeric aluminum of from about 2% to about 20% of the total aluminum.

Enhanced efficacy antiperspirant active

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&#xb0; 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.

Process for coating detergent granules in a fluidized bed

A process for the production of granular detergent compositions is provided wherein fluid bed granulation is employed in conjunction with selected recycle of oversized particles to control the uniformity of the resulting detergent composition. The process comprises feeding starting ingredients into a fluid bed granulator to at least partially granulate the feed material while employing the fluid bed to control undersized particle generation and sizing in conjunction with recycle to control oversized particles.

Process for making granular detergent in a fluidized bed granulator having recycling of improperly sized particles

A process for preparing coated detergent granules in a fluidized bed is provided. The fluidized bed is operated at a flux number of at least about 3.5 and/or a Stokes Number of greater than 1.0. 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 non-tower process for continuously preparing a granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, and (b) thoroughly mixing the agglomerates in a mixer. Step (b) can also be followed by further step (c), i.e., granulating the agglomerates from step (b) in one or more fluidizing apparatus, during which further coating can be used to prevent over-agglomeration.

Process for making a detergent composition by non-tower process

A process for producing a low density detergent composition is provided. The process involves: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material in a first high speed mixer to obtain detergent agglomerates; (b) mixing the detergent agglomerates in a second high speed mixer to obtain built-up agglomerates; and (c) feeding the built-up agglomerates and a binder into a fluid bed dryer to form detergent agglomerates having a density in a range from about 300 g/l to about 550 g/l, the fluid bed dryer being operated at a Stokes Number of less than about 1, wherein Stokes Number&equals;8&rgr;&ngr;d/9&mgr;, &rgr; is the apparent particle density of the built-up agglomerates, &ngr; is the excess velocity of the built-up agglomerates, d is the mean particle diameter of the built-up agglomerates and &mgr; is the viscosity of the binder.

Process for making a low density detergent composition by controlled agglomeration in a fluid bed dryer

A non-tower process for continuously preparing granular detergent compositions having a density of at least of about 600 g/l comprises the steps of (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, wherein first agglomerates are formed and (b) granulating the first agglomerates in one or more fluidizing apparatus.

Process for making a low density detergent composition by agglomeration

A process for continuously preparing low density detergent agglomerates is provided. The process comprises the steps of: (a) spray drying an aqueous mixture of sodium sulfate, sodium carbonate and a minor amount of a surfactant so as to form spray dried granules containing an inorganic double salt having the formula Na.sub.2 SO.sub.4 .multidot.Na.sub.2 CO.sub.3 and a minor amount of the surfactant; (b) agglomerating the spray dried granules with a detergent surfactant paste or precursor thereof and adjunct detergent material initially in a high speed mixer and subsequently in a moderate speed mixer to obtain detergent agglomerates, wherein the adjunct detergent material includes an adjunct sodium carbonate material; and (c) drying or cooling the detergent agglomerates so as to form the detergent composition having a density of below about 500 g/l.

A process for continuously preparing low density detergent agglomerate is provided. The process comprises the steps of: (a) agglomerating a detergent surfactant paste and dry starting detergent material in a high speed mixer to obtain detergent agglomerates, wherein the dry starting detergent material includes a hydrated salt; and (b) drying the detergent agglomerates so as to form the detergent composition having a density of less than about 600 g/l.

A process for continuously preparing low density detergent agglomerates having a density of below about 500 g/l is provided. The process comprises the steps of: (a) agglomerating a detergent surfactant paste or liquid acid precursor of anionic surfactant and dry starting detergent material in a high speed mixer to obtain detergent agglomerates, wherein the dry starting detergent material includes an inorganic double salt and sodium carbonate in a weight ratio of from about 1:10 to about 10:1; and (b) drying the detergent agglomerates so as to form the low density detergent composition having a density below about 600 g/l.
