Abstract:
A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the overall steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder in a mixer, wherein first agglomerates are formed; (b) spraying finely atomized liquid onto the first agglomerates in a mixer, wherein second agglomerates are formed; and (c) granulating the third agglomerates in one or more fluidizing apparatus. The process is improved by further step (b'), by thoroughly mixing the second agglomerates in a mixer, between step (b) and step (c), wherein, in step (b'), choppers are used to reduce the amount of oversized agglomerates.

Abstract:
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.
Abstract:
A process for continuously preparing a free flowing agglomerate having a reduced level of resulting undesirable oversized granules is provided. The process comprises the steps of (a) thoroughly mixing a crystalline anionic surfactant paste with a sufficient amount of fine powders of starting detergent materials to form a free flowing agglomerate, then (b) thoroughly mixing a product of the step (a) with a non-crystalline anionic surfactant paste so as to form a free flowing agglomerate.

Abstract:
Disclosed is a pump dispenser with a dip tube for dispensing a liquid product from a package, wherein the dip tube comprises a tube portion and a tip portion at the lower end of the tube portion, and the dip tube has a shape such that it is spread at the tip portion. The pump dispenser of the present invention provides improved dispensability of the liquid products.
Abstract:
A process for 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 disclosed. The process includes mixing in at least one high-speed, low-speed, or a moderate-speed mixer, and various combinations of such mixers, at least two materials selected from the group consisting of dry agglomerates, wet agglomerates, spray dried granules, and detergent adjunct ingredients to form particles. Optionally a conditioning apparatus may also be used. The granular detergent composition made from this process is aesthetically pleasing to consumers and has improved flowability.
Abstract:
The present invention relates to a process for forming an agglomerated particle containing the steps of providing at least one alkaline material, a core material, and at least one acid active. The alkaline material and the core material are added to a mixer and agglomerated therein, to form an agglomerated particle comprising an interior and an exterior. The acid active is then added to the mixer. The core material is concentrated into the interior of the agglomerated particle by adding substantially all of the core material to the alkaline material before more than about 50% of the acid active is added to the mixer.
