Problems solved by technology

[0005] When activated citrus fiber is used, especially when it is used at a level high enough to suspend solid particles (i.e., it has a sufficiently high yield stress), when the externally structured liquid detergent composition is When the interior of the container of the liquid composition is drained, for example after a portion of the liquid has been poured from the container, there is the problem of leaving a residue

Embodiment 1 to Embodiment 4

[0140] Example 1 to Example 4-Structured detergent liquid

[0141] The detergent liquid specified in the following examples is made using the 2 wt% activated citrus fiber premix described above. Sufficient freshly prepared premix is ​​added to the mixer to obtain the desired level of activated citrus fiber in the finished composition, and it is ground for 10 minutes. The polymer and the remaining ingredients that make up the liquid are then combined with this mixture. Finally combine the perfume encapsulant (when used). Online Silverson (L5T) was used for the dispersion.

[0142] The liquid polymer and activated citrus fiber content are as given in Table 2. Two detergent bases were used with three different thickening polymers: Base A: Table 3 and Base B: Table 4.

[0156] Example 5, Example 6 and C discharge residue

[0157] Use the polymers in Matrix A to prepare other compositions. The polymer content is as given in Table 5. The composition was added to a clear Nunc bottle to evaluate the visible residue. The bottle is manipulated to ensure that the sample completely wets the vertical wall, and then left for a few minutes to discharge. In contrast to the comparative liquid C made using the same detergent matrix and structured with 0.25% activated citrus fibers, the resulting wall discharge residue was visually evaluated. In all cases, the emission residue from the example of activated citrus fiber and polymer according to the present invention was visually lower than 0.25 wt% in the comparative example. 0.25 wt% was chosen as the actual comparison because it is the amount of citrus fiber needed to stably suspend the fragrance encapsulant. We also tested other polymers in different isotropic liquid detergent matrices and achieved th...

Abstract

An externally structured aqueous isotropic detergent liquid comprising: a) at least 10 wt% water, b) at least 3 wt% mixed detersive surfactant comprising anionic surfactant, c) at least 0.025 wt% of activated citrus fibre external structurant, characterised in that the liquid further comprises at least 0.1 wt% of water swellable polyacrylate thickening polymer and the viscosity of the liquid at 20 s-1 and 25°C is at least 0.3 Pa.s.

Description

technical field [0001] The present invention relates to externally structured aqueous isotropic liquid detergent compositions. Background technique [0002] Isotropic liquid detergent compositions do not have an inherent ability to suspend solid particles such as cues and encapsulates. The suspension medium can be achieved by appropriate manipulation of surfactant and electrolyte content. However, this imposes an undesirable limitation on the composition. The use of so-called external structurants can achieve the desired suspension duty without imposing such restrictions on the composition. [0003] Citrus fibers and their use for structuring food and personal care compositions are described in US2004 / 0086626 and US2009 / 269376. Compatibility of activated citrus fiber structured detergent liquids with detergent and care enzymes is described in PCT / EP2011 / 067549. Its use with a cationic deposition polymer (JAGUAR quaternized guar gum) for anti-dandruff shampoos is disclose...
