Neutral-pH Deodorant Composition for Aldehyde and Acid Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deodorants fail to efficiently capture aldehydes and carboxylic acids at neutral pH, leading to odor persistence and potential health risks, and can cause corrosion in metal products.
Innovation Solution
A deodorant comprising a carboxy group-containing O-substituted monohydroxylamine or its chemically acceptable salt, combined with an amine, effectively captures aldehydes and carboxylic acids at neutral pH, using a pH range of 5 to 9 to prevent corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If inorganic porous materials such as silica gel and activated carbon are used as deodorants, then the deodorant structure is simple and easy to manufacture, but the capture efficiency of low-grade aldehydes is low due to their low boiling points
Solution Approach 1:
The patent uses composite materials by combining inorganic porous materials (silica gel, activated carbon) with organic compounds (hydrazine derivatives, amines, amino acids, or urea derivatives) to create a deodorant that maintains the simple structure and ease of manufacture while achieving high aldehyde capture efficiency through chemical reaction mechanisms
2Productivity
If hydrazine derivatives, amines, amino acids, or urea derivatives are used to capture aldehydes through chemical reaction, then the capture mechanism is enhanced, but the deodorants themselves become odor sources and aldehydes are re-released over time
Solution Approach 1:
The patent optimizes the molecular structure parameters of the organic compounds used in the deodorant, specifically selecting compounds with appropriate functional groups and molecular weights to enhance capture efficiency while minimizing odor generation and aldehyde re-release through controlled chemical reactions
Solution Approach 2:
The patent introduces inorganic porous materials as intermediaries that facilitate the chemical reaction between deodorant components and aldehydes, improving capture efficiency while the porous structure allows for controlled release and reduces direct contact between reactive compounds and the environment, minimizing odor and re-release
3Adaptability or versatility
If deodorants are used in residences or automobiles during hot weather, then the deodorizing function is needed, but the performance of the deodorants deteriorates due to high temperature
Solution Approach 1:
The patent modifies the chemical composition parameters of the deodorant by incorporating thermally stable compounds and optimizing the ratio of organic to inorganic components, enabling the deodorant to maintain its aldehyde capture efficiency and structural stability under high temperature conditions typical of residences and automobiles during summer
4Productivity
If deodorants with acidic or basic nature are applied to automobile interior materials, then the deodorizing effect is achieved, but corrosion problems occur in products and metals used in the manufacturing process
Solution Approach 1:
The patent adjusts the pH parameters of the deodorant formulation by selecting organic compounds with neutral or mild properties and controlling the composition ratios, thereby maintaining effective aldehyde and carboxylic acid capture while minimizing corrosive effects on automobile interior materials and metals
Solution Approach 2:
The patent uses inorganic porous materials as intermediaries that buffer the interaction between the deodorant's organic compounds and metal surfaces, allowing the deodorant to maintain its deodorizing function while reducing direct corrosive contact with metals and products in the manufacturing process
