Laundry Additive Emulsion for Low-Temperature Dust Mite Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry compositions struggle to efficiently kill dust mites and deactivate allergens present in textiles due to the incompatibility of miticides with aqueous laundry conditions, and high temperatures required for effective dust mite removal can damage certain textiles.
Innovation Solution
Development of stable, non-hazardous, aqueous laundry formulations in the form of oil-in-water emulsions containing benzyl benzoate as a miticide and optional allergen denaturants, stabilized by emulsifiers and pH modifiers, suitable for use in domestic laundry cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high temperatures are used to kill dust mites, then dust mite removal effectiveness is improved, but textile damage increases
Solution Approach 1:
The patent changes the parameter of killing temperature from high temperature (60-90°C) to low temperature (0-40°C) by introducing a miticide agent (benzyl benzoate) that enables dust mite death at lower temperatures, thereby resolving the contradiction between effective dust mite removal and textile damage prevention
Solution Approach 2:
The patent introduces a miticide agent (benzyl benzoate) as an intermediary substance that mediates between the washing process and dust mites, enabling effective dust mite control without requiring high temperatures that would damage textiles. The agent acts as a chemical mediator that achieves the killing function at safe temperatures
2Reliability
If miticides are added to kill dust mites, then dust mite removal effectiveness is improved, but compatibility with aqueous laundry conditions deteriorates
Solution Approach 1:
The patent uses emulsifiers as intermediary substances that bridge the incompatible miticide (benzyl benzoate) and aqueous laundry conditions. The emulsifier forms an oil-in-water emulsion that allows the hydrophobic miticide to be delivered effectively in an aqueous environment, resolving the compatibility issue
Solution Approach 2:
The patent creates a composite formulation combining miticide, emulsifier, and water into an integrated oil-in-water emulsion system. This composite material combines the dust-mite-killing capability of benzyl benzoate with the aqueous compatibility of emulsifiers, achieving both effectiveness and adaptability simultaneously
