Stacked multi-compartment water-soluble unit dose automatic dishwashing detergent pouch

Abstract

A nested multi-compartment water-soluble unit dose automatic dishwashing detergent pouch having specific dimensions and configuration.

Description

[Technical Field]

[0001] The present invention relates to a nested, multi-compartment, water-soluble, unit dose automatic dishwashing detergent pouch having specific dimensions and configurations. [Background technology]

[0002] A highly desirable automatic dishwashing detergent product is a nested pouch containing one section nested on top of a second section.

[0003] Consumers prefer the convenience of a unit dose product form and not having to dispense a free-flowing powder or liquid from a container such as a bottle into the dispensing drawer of an automatic dishwasher, which can be cumbersome and can result in variability in the amount of detergent dispensed and therefore in the performance of the wash cycle.

[0004] The multi-compartment aspect of the pouch also means that detergent formulators can more easily combine liquid and solid ingredients in one product format. For example, having one inner compartment containing the solid portion and a second (and different) inner compartment containing the liquid portion. This means that detergent formulators can incorporate a wider range of chemicals into their detergent products, often enabling increased performance in multiple benefit spaces, such as improved cleaning performance, as well as improved stain prevention, drying, care, and shine performance.

[0005] The nested pouch configuration is also a desirable aspect of detergent products: nested pouches tend to be more rigid and stable than other pouch configurations, such as side-by-side pouch configurations, and tend to be more ergonomic and easier to handle and use.

[0006] One drawback of these stacked unit dose pouches is the amount of chemicals that can be incorporated into the product, while still allowing the pouch to be easily used by the dispenser drawer.When incorporating more chemicals into the pouch, the size of the pouch and its dimensions need to be carefully controlled to enable good performance and ease of use.As well as ease of use, the size and dimensions of the stacked sections also need to be carefully controlled to improve performance.The release from the dispenser drawer and the dissolution rate in rinse water are all affected by the size and dimensions of the pouch sections.

[0007] Increasing the pouch size and increasing the volume available for the detergent composition also allows for improved formulation strategies, such as improving the cleaning performance, shine performance, stain prevention performance, care performance, and environmental performance of the detergent product, as well as having economical cost and manufacturing efficiencies. The selection of the size and dimensions of each section of the stacked pouch influences the formulation strategy to achieve these improved performances.

[0060] The surfactant suitable for use herein includes nonionic surfactant, and preferably, the composition does not contain any other surfactant.Traditionally, nonionic surfactant has been used in automatic dishwashing for surface modification purposes, particularly for the purpose of sheeting to avoid film formation and spot formation and improve gloss.It has been found that nonionic surfactant can also contribute to preventing redeposition of dirt.

[0061] Preferably, the composition comprises a nonionic surfactant, preferably a nonionic surfactant system; more preferably, the nonionic surfactant or nonionic surfactant system has a phase inversion temperature, measured at a concentration of 1% in distilled water, between 20 and 70°C, preferably between 35 and 65°C. By "nonionic surfactant system" herein is meant a mixture of two or more nonionic surfactants. Nonionic surfactant systems are preferred for use herein. They are believed to have improved cleaning and finishing properties and better stability in products than single nonionic surfactants.

[0062] The phase inversion temperature is the temperature below which a surfactant or mixture thereof will preferentially partition into an aqueous phase as oil-swollen micelles and above which it will preferentially partition into an oily phase as water-swollen reverse micelles. The phase inversion temperature can be determined visually by identifying the temperature at which turbidity occurs.

[0063] The phase inversion temperature of a nonionic surfactant or system can be determined as follows: A solution containing 1% of the corresponding surfactant or mixture by weight of the solution is prepared in distilled water. After gently stirring the solution, the phase inversion temperature is analyzed to ensure that the process occurs at chemical equilibrium. The phase inversion temperature is measured in a thermostable bath by immersing the solution in a 75 mm sealed glass test tube. To ensure there are no leaks, the test tube is weighed before and after measuring the phase inversion temperature. The temperature is gradually increased at a rate of less than 1°C / min until it reaches a few degrees below the pre-estimated phase inversion temperature. The phase inversion temperature is determined visually at the first sign of turbidity.
