Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pepper spray products exhibit significant variability in capsaicinoid concentrations, leading to inconsistent performance and safety, and there is a lack of effective means to cleanse and mitigate the physiological effects of capsaicinoid exposure.
Innovation Solution
Development of capsaicinoid cleansing compositions that include a carrier, surfactant, chelating agent, and keratinolytic or anti-inflammatory agents to absorb and neutralize capsaicinoids from the skin, along with therapeutic compositions containing cooling agents and capsaicin receptor antagonists to inhibit calcium flux and reduce inflammation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pepper spray products use crude OC extract with variable capsaicinoid concentrations, then manufacturing simplicity is maintained, but performance consistency and safety reliability deteriorate
Solution Approach 1:
The patent applies parameter changes by establishing specific concentration ranges for capsaicinoid components (e.g., capsaicin 1-10%, dihydrocapsaicin 1-10%, nonivamide 1-10%) in the pepper spray formulation. This transforms the variable composition problem into a controlled parameter specification, ensuring consistent performance while maintaining manufacturing feasibility through defined compositional boundaries.
Solution Approach 2:
The invention uses composite materials by combining multiple capsaicinoid components (capsaicin, dihydrocapsaicin, and nonivamide) in specific proportions within a unified spray composition. This composite approach provides performance consistency through synergistic effects while maintaining ease of manufacture by using naturally occurring or readily synthesizable compounds.
2Ease of operation
If traditional water washing is used to cleanse capsaicinoid exposure, then simplicity of treatment is maintained, but effectiveness of capsaicinoid removal and physiological effect mitigation deteriorates
Solution Approach 1:
The patent introduces an intermediary substance - a cleansing composition containing surfactants, chelating agents, and keratinolytic agents - that mediates between the capsaicinoid contaminant and the skin. This intermediary formulation enhances the removal effectiveness by chemically interacting with capsaicinoid molecules and facilitating their extraction from skin surfaces, overcoming the limitations of simple water washing.
Solution Approach 2:
The invention employs a composite cleansing formulation combining multiple functional components: surfactants for emulsification, chelating agents for metal ion binding, and keratinolytic agents for skin protein degradation. This composite material approach provides superior cleansing effectiveness by addressing multiple mechanisms of capsaicinoid adhesion simultaneously, while remaining practical for field application.
3Device complexity
If no therapeutic intervention is applied after capsaicinoid exposure, then treatment complexity is minimized, but physiological effect mitigation and safety deteriorate
Solution Approach 1:
The patent applies preliminary action by incorporating therapeutic agents (cooling agents, capsaicin receptor antagonists, anti-inflammatory agents) into the cleansing composition itself, enabling treatment to begin immediately upon application. This pre-integrated approach mitigates physiological effects early in the exposure response cycle, preventing severe reactions while avoiding the complexity of separate treatment steps.
Solution Approach 2:
The invention merges cleansing and therapeutic functions into a single integrated composition. By combining capsaicinoid removal agents with therapeutic interventions (cooling agents, receptor antagonists, anti-inflammatories) in one formulation, the patent reduces treatment complexity while enhancing safety through simultaneous decontamination and physiological effect mitigation.
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 compositions effectively absorb and neutralize capsaicinoids, reducing their concentration on the skin and mitigating the associated physiological effects, providing rapid relief and preventing reactivation, thus improving safety and performance of pepper spray use.
Implementation Method 1
a surfactant in an effective amount within the carrier sufficient to transport the capsaicinoid from the skin and into the carrier
Implementation Method 2
a chelator in an effective amount within the carrier sufficient to chelate free calcium at the skin
Implementation Method 3
a cooling agent in an effective amount within the carrier to provide a cooling sensation to the skin

AI summary
A method for cleansing and treating skin exposed to a capsaicin or derivative thereof so as to inhibit capsaicin reactivation includes: providing a subject having exposure to capsaicin, oleoresin capsicum, or other capsaicinoid derivative; cleansing capsaicin, oleoresin capsicum, or other capsaicinoid derivative from skin of the subject with a cleansing composition having: a carrier; a surfactant and/or detergent; a chelating agent; and salicylic acid, acetylsalicylic acid, or ibuprofen; and treating the skin of the subject with a therapeutic composition so as to inhibit reactivation of effects of capsaicin, oleoresin capsicum, or other capsaicinoid derivative exposure, the therapeutic composition having: a carrier; aloe; a thickening agent; and salicylic acid, acetylsalicylic acid, or ibuprofen.
