Liquid detergent compositions, single dose packs including the same, and methods of forming single dose packs are provided herein. In an embodiment, a liquid detergent composition includes an ionic surfactant, an alkoxylated linear fatty acid structurant, and, optionally, a particulate component. The structurant is solid at ambient temperature of about 21&#xb0; C. and ambient pressure of about 100 kPa. The particulate component is different from the structurant. The detergent composition exhibits non-Newtonian fluid behavior at 24 hours following shear mixing cessation.

Liquid detergent compositions including structurant, single dose packs including the same, and methods of forming the single dose packs

A method for maintaining a consistent, low viscosity profile of a unit dose detergent composition for enhanced hydration and dissolution upon hydration including the steps of: (1) providing a detergent composition including: 0.4 to 9.6 wt. % of an alkoxylated polyamine including an alkoxylated polyamine, an alkyl-ether sulfate, a linear alkylbenzene sulfonate, and a fatty alcohol ethoxylate, wherein the alkyl-ether sulfate, linear alkylbenzene sulfonate, and fatty alcohol ethoxylate are collectively present in an amount of 30 to 70 wt. %, by weight of the detergent composition; and (2) encapsulating the detergent composition in a pouch made of a water soluble film.

Use of alkoxylated polyamines to control rheology of unit dose detergent compositions

A method for maintaining a consistent, low viscosity profile of a unit dose detergent composition for enhanced hydration and dissolution upon hydration including the steps of: (1) A method for maintaining a consistent, low viscosity profile of a unit dose detergent composition for enhanced hydration and dissolution upon hydration including the steps of: (1) providing the detergent composition including: about 2.5 to about 15 wt. % of a polyglycol, an alkyl-ether sulfate, a linear alkylbenzene sulfonate, and a fatty alcohol ethoxylate, wherein the alkyl-ether sulfate, linear alkylbenzene sulfonate, and fatty alcohol ethoxylate are collectively present in an amount of 30 to 70 wt. %, by weight of the detergent composition; and (2) encapsulating the detergent composition in a pouch made of a water soluble film.

Use of polyglycols to control rheology of unit dose detergent compositions

In one embodiment, a polyethoxylated alcohol sulfate composition is provided which includes a polyethoxylated alcohol sulfate, such as sodium laureth ether sulfate (SLES), water, an ionic liquid, and an alcohol. The ionic liquid and the alcohol form a synergistic blend, enabling a significant reduction of the viscosity of the polyethoxylated alcohol sulfate composition. Also provided is an embodiment of a method for modifying the rheology of polyethoxylated alcohol sulfate by use of an ionic liquid and alcohol blend. Finally provided is an embodiment of a detergent composition which is prepared by use of the polyethoxylated alcohol sulfate composition described herein, in addition to other commonly known ingredients.

Use of an ionic liquid and alcohol blend to modify the rheology of polyethoxylated alcohol sulfates

In one embodiment, a polyethoxylated alcohol sulfate composition is provided which includes a polyethoxylated alcohol sulfate, such as sodium laureth ether sulfate (SLES), water, a mono-alcohol, and a polyol. The two alcohols form a synergistic blend, enabling a significant reduction of the viscosity of the polyethoxylated alcohol sulfate composition. Also provided is an embodiment of a method for modifying the rheology of polyethoxylated alcohol sulfate by use of a mono-alcohol and a polyol simultaneously. Finally provided is an embodiment of a detergent composition which is prepared by use of the polyethoxylated alcohol sulfate composition described herein, in addition to other commonly known ingredients.

Use of an alcohol hybrid to modify the rheology of polyethoxylated alcohol sulfates

Stable unit dose compositions with high water content are provided. Such unit dose compositions include an aqueous composition having a water activity of from about 0.65 to about 0.95 and a water-soluble container formed from a water-soluble or water-dispersible film material. In one embodiment, the aqueous composition includes water in an amount of 25% to 70% by weight, a surfactant system, and a water binding agent. The surfactant system may include: (1) a linear alkylbenzene sulfonate (LAS) and/or an alcohol ethoxylsulfate (AES), (2) a non-ionic surfactant, and (3) a fatty acid. The unit dose compositions can prevent the enclosed liquid detergent composition with a high level of water content from dissolving or pre-maturely dispersing the water-soluble container.

Stable unit dose compositions with high water content

A single dose pack and methods for producing and using the same are provided. In one embodiment, a single dose pack includes a container, wherein the container comprises a water-soluble film, and a wash composition encapsulated within the container. The wash composition includes a detergent surfactant, water present in an amount of from about 8 to about 40 weight percent, based on the total weight of the wash composition, and a polyethylene glycol (PEG) blend. The PEG blend includes at least one relatively higher molecular weight (MW) PEG having an average MW of about 1500 Daltons or greater in combination with at least one relatively lower MW PEG having an average MW of about 400 Daltons or less and/or at least one mid-MW PEG having an average MW of between about 400 and about 1500 Daltons.

Detergent single dose packs and methods of producing the same

Stable unit dose compositions with high water content are provided. Such unit dose compositions include an aqueous composition having a water activity of from about 0.60 to about 0.95 and a water-soluble container formed from a water-soluble or water-dispersible film material. In one embodiment, the aqueous composition includes water in an amount of 20% to 70% by weight, a structured surfactant system which is in the form of a lamellar structure, and a salt which promotes the formation of the lamellar structure. The surfactant system may include: (1) a linear alkylbenzene sulfonate (LAS) and/or an alcohol ethoxylsulfate (AES), (2) a non-ionic surfactant, and (3) a fatty acid. The unit dose compositions can prevent the enclosed liquid detergent composition with a high level of water content from dissolving or pre-maturely dispersing the water-soluble container due to the lamellar structure of the composition.
