Multi-phase unit-dose cleaning product malodour control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning products containing amine-based actives often generate unpleasant malodours due to interactions with other components, which can lead to consumer dissatisfaction, especially when packaged in confined spaces.
Innovation Solution
A multi-phase unit-dose cleaning product is developed, where at least 30% of the amine-containing cleaning active and oxidizing agent are in different phases, typically in a water-soluble pouch with a permeable enveloping material, allowing for the escape of amine-based malodours and maintaining a pleasant olfactory profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If amine-containing cleaning active is used in high concentration, then cleaning performance is improved, but malodour is generated
Solution Approach 1:
The cleaning product is divided into multiple phases (aqueous phase and organic phase) with the amine-containing cleaning active distributed between them. At least 30% of the amine is in a phase separate from the oxidizing agent, reducing harmful interactions and malodour generation while maintaining cleaning effectiveness.
2Object-generated harmful factors
If strong perfume is added to mask malodour, then olfactory profile is improved, but consumer acceptance deteriorates
Solution Approach 1:
The invention converts the potentially harmful interaction between amine and oxidizing agent into a beneficial outcome by separating them into different phases. This prevents malodour formation at the source rather than masking it, making the product safe for food contact surfaces while maintaining good olfactory profile without requiring strong perfumes.
3Reliability
If amine-containing cleaning active interacts with oxidizing agent, then cleaning effectiveness is improved, but malodour is generated
Solution Approach 1:
The product separates amine-containing cleaning active and oxidizing agent into different phases to prevent harmful interactions during storage and handling, while still allowing cleaning effectiveness when needed. The multi-phase structure enables controlled interaction only during application.
Solution Approach 2:
Different phases of the cleaning product have different compositions and functions. The aqueous phase contains oxidizing agents while the organic phase contains amine-containing actives, allowing each component to perform its optimal function locally without generating malodour through unwanted interactions.
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
The product effectively reduces malodour issues and provides a good olfactory profile even with high concentrations of amine-containing cleaning actives, such as aminocarboxylic complexing agents and bleach, ensuring consumer acceptance.
Implementation Method 1
Preferred for use herein are pouches, in which the cleaning composition is wrapped in water-soluble material preferably made of polyvinyl alcohol, preferably having a thickness of less than 100 μm. These films are permeable to amine based malodours.
