Laundry Detergent Enzyme Delivery Particles for Benefit Agent Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Benefit agents in laundry detergents, such as perfumes and fabric softening agents, are often expensive and less effective due to poor delivery efficiencies, which can be attributed to their physical or chemical characteristics and incompatibility with other composition components or the fabric surface.
Innovation Solution
A laundry detergent composition incorporating a glycosyl hydrolase enzyme and benefit agent-containing delivery particles with specific physical and chemical characteristics, including a core and wall material, enhances the entrapment and retention of benefit agents on fabric surfaces, improving their performance during the laundering process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If benefit agents are employed at high levels in fabric care compositions, then the effectiveness should be improved, but the cost increases and physical/chemical loss occurs
Solution Approach 1:
The benefit agent is encapsulated within a delivery particle consisting of a core material surrounded by a wall material. This nested structure protects the benefit agent from physical or chemical loss while enabling controlled delivery to the fabric surface, thereby maintaining effectiveness without requiring high levels of the expensive agent.
Solution Approach 2:
The delivery particle employs a wall material that at least partially surrounds the core material containing the benefit agent. This shell structure provides protection against loss while allowing controlled release, resolving the contradiction between maintaining effectiveness and reducing substance loss.
2Reliability
If delivery efficiency of benefit agents is improved, then the effectiveness increases, but the complexity of composition increases
Solution Approach 1:
The delivery particle serves multiple functions: it protects the benefit agent from loss, controls its delivery to the fabric surface, and enhances entrapment within fabric pores through the action of glycosyl hydrolase. This multi-functionality improves delivery efficiency without proportionally increasing composition complexity.
Solution Approach 2:
The delivery particle acts as an intermediary carrier between the benefit agent and the fabric surface. It mediates the delivery process by protecting the agent during formulation and application, then releasing it at the target site, thereby improving delivery efficiency while managing composition complexity.
3Quantity of substance
If glycosyl hydrolase is added to open fabric pore structure, then the entrapment of benefit agent particles increases, but the composition complexity increases
Solution Approach 1:
The glycosyl hydrolase is included in the detergent composition to preliminarily modify the fabric surface by opening pore structures before the benefit agent is delivered. This preliminary action enhances subsequent entrapment of the benefit agent particles without requiring complex additional mechanisms.
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 use of glycosyl hydrolase enzymes and tailored delivery particles increases the surface area of fabric pores, leading to improved retention and effectiveness of benefit agents, thereby enhancing the overall performance and efficiency of laundry detergents.
Implementation Method 1
the action of certain glycosyl hydrolase on the fabric surface opens up the pore structure of the cotton fibres so as to increase the entrapment of the benefit agent containing particles in the fabric
Implementation Method 2
the action of these certain glycosyl hydrolases increases the surface area of the fabric, further improving the performance of the benefit agent during the laundering process
