Solution Overview
Problem
Existing insecticides with high melting points and low solubility struggle to achieve effective contact efficacy for short-term pest control due to crystalline structures, leading to limited uptake and resistance issues, particularly in vector and pest management applications.
Innovation Solution
Formulating insecticidal active ingredients with high melting points and low solubility into a wax matrix with controlled particle sizes (0.1 to 75 microns) to enhance contact efficacy and resistance breaking potential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insecticidal active ingredients with high melting points and low solubility are used, then biological activity and resistance breaking potential are improved, but contact efficacy is reduced due to crystalline structures forming poorly soluble forms
Solution Approach 1:
The patent changes the physical state parameter of the insecticidal active ingredient from crystalline to amorphous form through formulation in polyol matrix. This parameter change enables the ingredient to maintain high biological activity and resistance breaking potential while achieving effective contact efficacy, as the amorphous form prevents crystallization and improves bioavailability.
Solution Approach 2:
The patent introduces a polyol matrix as an intermediary substance that carries the insecticidal active ingredient. This intermediary formulation system allows the ingredient to be delivered in amorphous form, preventing crystallization during application and enabling both high biological activity and effective contact efficacy to be achieved simultaneously.
2Ease of manufacture
If conventional suspension concentrate formulations are used for crystalline insecticidal active ingredients, then manufacturing is straightforward, but uptake by insects is limited due to poor solubility
Solution Approach 1:
The patent changes the physical state parameter of the insecticidal active ingredient from crystalline to amorphous form through formulation in polyol matrix. This parameter change enables the ingredient to maintain high biological activity and resistance breaking potential while achieving effective contact efficacy, as the amorphous form prevents crystallization and improves bioavailability.
Solution Approach 2:
The patent introduces a polyol matrix as an intermediary substance that carries the insecticidal active ingredient. This intermediary formulation system allows the ingredient to be delivered in amorphous form, preventing crystallization during application and enabling both high biological activity and effective contact efficacy to be achieved simultaneously.
3Duration of action of stationary object
If controlled release formulations based on polymer or wax matrices are used, then residual biological efficacy is prolonged, but initial biological efficacy and contact efficacy are reduced
Solution Approach 1:
The patent applies local quality by creating a formulation where the polyol matrix provides controlled release properties for prolonged residual efficacy, while simultaneously incorporating adjuvants and optimizing particle size to ensure high initial biological efficacy and contact efficacy are not compromised. The formulation is designed to release the active ingredient in a controlled manner that maintains both immediate and long-term effectiveness.
