Oxime Carbamate Liquid Soluble Concentrate Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stability of oxime carbamates, such as oxamyl, in liquid formulations is low, leading to reduced effectiveness and the need for higher application rates, as they decompose in soil and water, which affects their efficacy in treating pest infestations.
Innovation Solution
A liquid soluble concentrate formulation comprising an oxime carbamate and a solvent system of alcohol, carbonate ester, and water, which enhances the stability and solubility of the active ingredient, allowing for higher concentrations and reduced volume requirements for application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If oxime carbamates are used in liquid formulations, then they can be applied conveniently and dissolved in water, but their stability is low and they decompose in soil and water
Solution Approach 1:
The patent introduces a stabilizing agent as an intermediary substance that mediates between the oxime carbamate active ingredient and the aqueous environment. This stabilizing agent prevents decomposition of the oxime carbamate in water and soil while maintaining the liquid formulation's applicability. The stabilizer acts as a protective intermediary that extends the half-life of the active ingredient without compromising ease of application.
2Reliability
If higher application rates are used to compensate for decomposition, then pest control effectiveness is maintained, but the volume of formulation required increases
Solution Approach 1:
The patent changes the chemical parameters of the formulation by introducing stabilizing agents and adjusting pH levels. These parameter changes increase the stability and half-life of the oxime carbamate, allowing lower application rates to achieve the same pest control effectiveness. By modifying the formulation's chemical environment, the active ingredient remains effective longer, reducing the quantity needed per application.
3Ease of manufacture
If conventional solvent systems are used, then the formulation can be prepared simply, but the solubility and stability of oxime carbamates are limited
Solution Approach 1:
The patent creates a composite liquid formulation system combining multiple components: oxime carbamate active ingredient, stabilizing agents, pH adjusters, and conventional solvents. This composite approach enhances solubility and stability beyond what conventional single-component systems achieve, while maintaining relative simplicity in preparation. The synergistic interaction between components improves overall formulation performance.
