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&#xb0; 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.

Process for making a granular detergent composition

A process for preparing detergent particles having a coating layer of water-soluble inorganic material is provided. The detergent particle comprises a particle core of a detergent active material. This particle core is then at least partially covered by a particle coating layer of a water soluble inorganic material. Particularly preferred are non-hydrate inorganic coating materials including double salt combinations of alkali metal carbonates, and sulfates. The particle coating layer may also include detergent adjunct ingredients such as brighteners, chelants, nonionic surfactants, co-builders, etc. The process includes the steps of passing the particle core through a coating mixer such as a low speed mixer of fluid bed mixer and coating the particle core with a coating solution or slurry of the water soluble inorganic material. Upon drying, the resultant detergent particles have improved appearance, flow properties, and improved solubility, 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 producing coated detergent particles

The present invention relates to a cationic particle containing an aqueous cationic surfactant solution adsorbed to a water-insoluble high absorbing material. Preferably, the water-insoluble high absorbing material has an oil absorption (using d-butyl phthalate) of from about 140 mL/100 g to about 400 mL/100 g. A process for making the cationic particle is also described herein. The cationic particle can be incorporated into a particulate detergent composition.

Cationic particle and a process for making thereof

An improved container contains a housing containing at least one aperture and a treatment composition located within the housing. The combination of the treatment composition and the housing has a mess factor of from about 3.6*10 to about 1.1*10 . When the housing is in a prepared state and squeezed, the treatment composition exits the housing from the aperture.

Composition and container for treating a vertical surface

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.

Process for forming an agglomerated particle

The present invention relates to a process for forming a cleaning composition containing the steps of providing at least one alkaline material and at least one acid active, and adding the acid active and the alkaline material to a mixer. The acid active is substantially neutralized within the mixer to form a neutralized detergent active. At least one acid-sensitive polymer is added to the neutralized detergent active to form a slurry, and the slurry is formed into a cleaning composition. A cleaning composition as formed by the above process is also described herein.

Process for forming a cleaning 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 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.

Process for making a detergent composition by adding co-surfactants

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 steps of (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, in a mixer, wherein first agglomerates are formed, (b) thoroughly mixing the first agglomerates in a mixer, wherein second agglomerates are formed, and (c) spraying finely atomized liquid onto the second agglomerates in a mixer.
