Amphoteric Chelating Agent Layer for Rubber Allergy Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact allergies, particularly to rubber, pose a significant public health issue due to the high prevalence among medical personnel and others frequently exposed to rubber products, leading to severe reactions like anaphylactic shock, and existing alternatives are either expensive or compromise touch sensitivity.
Innovation Solution
The use of an amphoteric chelating agent based on aluminum and ethylenediaminetetraacetic acid or its trisodium salt, applied as a layer on rubber products or in compositions, to prevent contact allergies by forming a chemical barrier that inhibits allergen uptake by skin cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If replacement products made of polyurethane, polyvinyl, or nitrile are used to prevent contact allergies, then allergy prevention is improved, but cost increases and touch sensitivity is compromised
Solution Approach 1:
The patent applies an amphoteric chelating agent layer as an intermediary substance between the skin and rubber products. This layer contains aluminum complexes that bind to allergenic proteins through chelation, preventing direct contact between allergens and skin while maintaining the original rubber product's tactile properties
Solution Approach 2:
The patent changes the chemical state of allergenic substances by applying chelating agents that alter their molecular structure through complex formation. This chemical modification reduces allergenicity while preserving the physical properties of the rubber product for normal use
2Reliability
If replacement products made of polyurethane, polyvinyl, or nitrile are used to prevent contact allergies, then allergy prevention is improved, but manufacturing cost increases
Solution Approach 1:
Instead of replacing expensive rubber products with costly alternative materials, the patent uses a disposable or reusable chelating agent coating that can be applied to inexpensive rubber products, maintaining low manufacturing costs while achieving allergy prevention
Solution Approach 2:
The patent creates a composite structure by combining traditional rubber materials with amphoteric chelating agents. This composite approach preserves the cost benefits of original rubber products while adding protective functionality through the chelating layer
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 amphoteric chelating agent effectively prevents contact allergies by forming a chemical barrier that reduces the migration of allergen-activating Langerhans cells, thereby minimizing allergic reactions such as dermatitis, urticaria, and anaphylactic shock without affecting touch sensitivity or increasing costs.
Implementation Method 1
The use of an amphoteric chelating agent based on aluminum and ethylenediaminetetraacetic acid or its trisodium salt, applied as a layer on rubber products or in compositions, to prevent contact allergies by forming a chemical barrier that inhibits allergen uptake by skin cells

AI summary
A method of preventing contact allergies includes using at least one amphoteric chelating agent which includes a complex based on aluminium and on ethylenediaminetetraacetic acid or the trisodium salt thereof, having the general formula [Al(Y)Bn]c′Dc with B being OH−, BO2− or H+, Y being a tetracarboxylate which can be protonated four times to form ethylenediaminetetraacetic acid, n being an integer equal to 0, 1, 2 or 3, D being a counterion, preferably Na+, c being an integer equal to 0, 1, 2 or 3 and c′ being a relative number having the same absolute value as c. A device, a part of which includes the amphoteric chelating agent, is also described.
