Solution Overview
Problem
Encapsulated benefit agents in personal care and fabric care compositions often require high levels of scavenger materials to manage residual formaldehyde, increasing formulation complexity and incompatibility with other components.
Innovation Solution
Developing encapsulated benefit agent delivery compositions with reduced scavenger material requirements, using processes like centrifugation, filtration, and solvent exchange to minimize shell particles and formaldehyde levels, thereby maintaining lower by-product levels and improving delivery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If scavenger materials are introduced into the slurry to remove residual formaldehyde, then formaldehyde levels are reduced, but formulation complexity increases and incompatibility with other compositional components occurs
Solution Approach 1:
The patent removes shell particles containing residual formaldehyde from the encapsulated benefit agent composition through filtration or centrifugation. This extraction approach eliminates the need for scavenger materials by physically removing the source of formaldehyde, thereby reducing formulation complexity while maintaining low formaldehyde levels.
Solution Approach 2:
The patent performs removal of shell particles containing formaldehyde before the encapsulated benefit agents are used in consumer products. This preliminary action prevents formaldehyde from being introduced into the final product formulation, eliminating the need for subsequent scavenger materials and simplifying the overall formulation.
2Object-affected harmful factors
If scavenger materials are introduced into the slurry to remove residual formaldehyde, then formaldehyde levels are reduced, but incompatibility with other raw materials occurs
Solution Approach 1:
The patent extracts shell particles containing residual formaldehyde through filtration or centrifugation, removing the harmful component without introducing scavenger materials. This approach maintains compatibility with all other raw materials while achieving low formaldehyde levels.
3Object-affected harmful factors
If shell particles are removed through centrifugation or filtration, then formaldehyde levels are reduced, but processing complexity increases
Solution Approach 1:
The patent performs centrifugation or filtration to remove shell particles at an early stage in the manufacturing process, before the encapsulated benefit agents are formulated into consumer products. This preliminary removal simplifies subsequent processing steps and eliminates the need for additional formaldehyde management steps.
