Description

Technical Field

[0001] The present invention relates to a stacked multi-compartment water-soluble unit dose automatic dishwashing detergent sachet having a specific size and configuration. Background Art

[0002] A highly desirable automatic dishwashing detergent product is a stacked sachet that includes one compartment stacked on a second compartment.

[0003] Consumers appreciate the convenience of unit dose product forms and do not have to dispense free-flowing powder or liquid from a container (such as a bottle) into the dispensing drawer of an automatic dishwashing machine, which can be messy and result in variations in the amount of detergent dispensed and thus variations in the performance of the wash cycle.

[0004] The multi-compartment aspect of the sachet also means that detergent formulators can more easily combine liquid and solid ingredients into one product form. For example, having an inner compartment containing a solid portion and a second (and different) inner compartment containing a liquid portion. This means that detergent formulators can incorporate a wider range of chemicals into the detergent product, which in turn can improve performance, typically with numerous beneficial aspects such as improved cleaning performance, and improved anti-staining, drying, care, and glean performance.

[0005] The stacked configuration of the sachet is also a desirable aspect of the detergent product. Stacked sachets tend to be more rigid, stable than other sachet forms (such as side-by-side sachet configurations), and tend to be more ergonomically preferred and easier to handle and use.

[0006] One drawback of these stacked unit dose sachets is the amount of chemicals that can be introduced into the product while still allowing the sachet to be easily used by the dispenser drawer. If more chemicals are to be incorporated into the sachet, the size and dimensions of the sachet need to be carefully controlled to achieve good performance and ease of use. In addition to ease of use, the size and dimensions of the stacked compartments also need to be carefully controlled to allow for improved performance. The rate of release from the dispenser drawer, dissolution into the wash water is affected by the size and dimensions of the compartments of the sachet.

[0007] Increasing the size of the sachet and the available volume of the detergent composition also allows for improved formulation strategies, such as improving the cleaning performance, gloss performance, anti-staining performance, care performance, environmental performance of the detergent product, and having an economical manufacturing cost and efficiency. The choice of the size and dimensions of each compartment of the stacked sachet affects the formulation strategies for achieving these improved performances. Summary of the Invention

[0008] The present invention provides a stacked multi-compartment water-soluble unit dose automatic dishwashing detergent sachet, wherein the sachet comprises a first compartment stacked onto a second compartment, wherein the first compartment comprises one or more internal compartments, wherein the second compartment comprises one or more internal compartments, wherein the sachet contains an automatic dishwashing detergent composition, wherein the automatic dishwashing detergent comprises a first component and a second component, wherein the first compartment of the sachet contains the first component of the detergent composition, and wherein the second compartment of the sachet contains the second component of the detergent composition.

[0142] 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 between 20 °C and 70 °C, preferably between 35 °C and 65 °C, as measured at a concentration of 1% in distilled water. The so-called "nonionic surfactant system" herein refers to a mixture of two or more nonionic surfactants. A nonionic surfactant system is preferably used herein. Compared with a single nonionic surfactant, the nonionic surfactant system appears to have improved cleaning and conditioning properties and better stability in the product.

[0143] The phase inversion temperature is the temperature at which, below which, the surfactant or its mixture preferentially partitions into the aqueous phase as oil-swollen micelles, and above which, partitions into the oil phase as water-swollen reverse micelles. The phase inversion temperature can be visually determined by identifying at which temperature turbidity occurs.

[0144] The phase inversion temperature of the nonionic surfactant or system can be determined as follows: Prepare a solution containing 1% by weight of the corresponding surfactant or mixture in distilled water. The solution is gently stirred before phase inversion temperature analysis to ensure that the process occurs under chemical equilibrium. The phase inversion temperature is obtained in a thermostatically controlled bath by immersing the solution in a 75 mm sealed glass test tube. To ensure no leakage, the test tube is weighed before and after phase inversion temperature measurement. The temperature is gradually increased at a rate of less than 1 °C / minute until the temperature reaches a few degrees below the estimated phase inversion temperature. The phase inversion temperature is visually determined at the first turbidity mark.

[0145] Suitable nonionic surfactants include: i) ethoxylated nonionic surfactants prepared by the reaction of a monohydroxy alkanol or alkylphenol having 6 to 20 carbon atoms with preferably at least 3 moles, particularly preferably at least 5 moles and even more preferably at least 7 moles of ethylene oxide per mole of alcohol or alkylphenol; ii) alcohol alkoxylated surfactants having 6 to 20 carbon atoms and at least one ethoxy and propoxy group.
