Problems solved by technology

In particular, it has been found that relatively high levels of some non-aqueous solvents do not provide stable liquid detergent compositions (e.g., phase separation and / or flocculation occurs), and that some non-aqueous solvents can cause "bleed-through", i.e., the solvent can Migrate through the water soluble film to the exterior of the water soluble unit dose product

Embodiment 1

[0122] Example 1: Stability of Unit Dose Preparations Containing Amine Oxide, Diol Solvent and Polyol Solvent

[0123] Five (5) sample unit dose articles comprising a liquid detergent composition were prepared containing the following ingredients, wherein all samples contained an amine oxide surfactant, anionic surfactant, nonionic surfactant, glycol solvent, and polybasic Alcohol solvents, where the ratio of diol solvent to polyol solvent is different. The liquid detergent composition (approximately 10ml) 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.

[0135] Three (3) sample unit dose articles comprising a liquid detergent composition were prepared containing the following ingredients, wherein all samples contained an amine oxide surfactant, anionic surfactant, nonionic surfactant, glycol solvent (i.e. , P-diol) and polyol solvent (ie, glycerol), and only sample 6 also contained a hydroxyl ether solvent (ie, DPG). 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.

Abstract

The invention relates to a water soluble unit dose article comprising an amine oxide surfactant, a diol solvent, and a polyol solvent. The present invention relates to water soluble unit dose articles comprising an amine oxide surfactant in combination with a diol solvent and a polyol solvent, and methods of making.

Description

technical field [0001] The present invention relates to water soluble unit dose formulations comprising amine oxide surfactants, diol solvents and polyol solvents, and methods of making. Background technique [0002] Water soluble unit dose products are preferred by consumers for their convenience and ease of use. Consumers also like the fact that they do not need to measure detergent doses, so this eliminates accidental spills during dosing operations. Accidental doses can be messy and inconvenient. [0003] On the other hand, amphoteric surfactants, especially amine oxide surfactants, are commonly used in personal care products (eg shower body lotions), hair care products (eg shampoos) and household care products (eg dishwashing). Amine oxide surfactants have excellent performance in grease cleaning. However, in the field of fabric care, the use of amine oxide surfactants is very limited. Formulating highly concentrated liquid detergent compositions in the presence of ...
