Embodiment 1

[0112] Example 1: Improved color protection when the detergent composition has a pH within a certain range

[0113] Five (5) sample unit dose articles comprising a liquid detergent composition were prepared containing the following ingredients, wherein all samples contained dye fixatives, anionic surfactants, nonionic surfactants, and amine-based surfactants, The difference is that the liquid detergent compositions have a different neat pH adjusted by the addition of citric acid and / or sodium hydroxide. The liquid detergent composition (approximately 10 ml) was encapsulated into unit dose compartments by using a polyvinyl alcohol based film, wherein the PVA film and unit dose had the same shape as CN Ariel Laundry dual compartment side-by-side sachets.

Embodiment 2

[0128] Example 2: Further improved color protection when MEA is used as pH regulator compared to sodium hydroxide

[0129] To explore whether pH adjusters have an effect on color protection performance, two (2) sample unit dose articles comprising liquid detergent compositions were prepared containing the following ingredients, wherein all samples contained dye fixatives, anionic surfactants, Non-ionic surfactants and amine oxides, except that the liquid detergent composition has a different pH adjuster (sodium hydroxide and citric acid for sample 6, and monoethanolamine, MEA for sample 7) . The liquid detergent composition (approximately 10 ml) was encapsulated into unit dose compartments by using a polyvinyl alcohol based film, wherein the PVA film and unit dose had the same shape as CN Ariel Laundry dual compartment side-by-side sachets.

[0130] The ΔE of these samples was measured as a measure of dye bleed according to Test 1 (Dye Bleed Test using fabrics colored with ...

Abstract

The invention relates to a water soluble unit dose article comprising a laundry detergent composition comprising a dye fixative. A water soluble unit dose article comprising a water soluble film and a detergent composition encapsulated within the water soluble film wherein the water soluble film comprises a water soluble polymer and the detergent composition comprises a dye fixative, and wherein the detergent composition has a net pH of 2.5 to 8.4.

Description

technical field [0001] The present invention relates to a water soluble unit dose article comprising a laundry detergent composition comprising a dye fixing agent. Background technique [0002] Detergent products in the form of unit dose compositions have become popular in recent years. Compared to conventional detergent powder or liquid detergent products, unit-dose laundry washing products can provide many benefits such as portability, no need for measurement and attractive appearance when used. Such unit dose products typically comprise a water soluble film encapsulating the liquid detergent surfactant therein. When added to water, such unit dose compositions will dissolve to release the detersive surfactant. Such water-soluble films comprise a water-soluble polymer preferably selected from polyvinyl alcohol, polyvinylpyrrolidone, polyalkylene oxide, acrylamide, acrylic acid, cellulose, cellulose ether, cellulose ester, fiber Vein amides, polyvinyl acetate, polycarboxy...
