Coloured Detergent Particles with Suspending Agent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent compositions with colored particles often cause staining or spotting on fabrics due to high concentrations of dyes or pigments, which limits their usage levels to avoid such issues.
Innovation Solution
Incorporating a suspending agent into colored particles with hueing agents, such as pigments or dyes, allows for higher usage levels without staining, as the agent slows down the deposition of the hueing agent in wash water, preventing localized concentration and subsequent fabric staining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dyes or pigments are incorporated into detergent compositions to provide blueing of wash water or aesthetic effects, then product aesthetics and perceived cleaning performance are improved, but fabric staining or spotting occurs due to localized high concentrations of coloring materials
Solution Approach 1:
A suspending agent is introduced as an intermediary substance between the hueing agent and the fabric. This suspending agent prevents direct contact between concentrated hueing agent and fabric by maintaining dispersion in the wash water, thereby eliminating the staining problem while allowing high levels of hueing agent to be used for aesthetic and cleaning performance benefits
2Productivity
If high levels of hueing agents are used in detergent compositions to enhance aesthetic effects and cleaning performance, then product effectiveness is improved, but fabric staining occurs due to localized concentration
Solution Approach 1:
The suspending agent acts as a mediator that allows high concentrations of hueing agents to be used effectively for cleaning performance and aesthetic purposes while preventing the harmful localized concentration effect that causes fabric staining. The suspending agent maintains uniform distribution of the hueing agent throughout the wash water
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the use of higher levels of hueing agents in detergent compositions without fabric staining, enhancing the aesthetic and cleaning performance while maintaining safety.
Implementation Method 1
by incorporating a suspending agent for the hueing agent in the coloured particles, the problems of the prior art are alleviated. Without wishing to be bound by theory the inventors believe that this is because on contact of the detergent composition with water, the coloured particles rapidly dissolve/disintegrate. However, the deposition of the hueing agent is slowed by the suspending agent until concentrated regions of hueing agent are dispersed
