Solution Overview
Problem
Current pesticidal formulations of emamectin benzoate rely on organic solvents, which are environmentally harmful and lead to instability, high production costs, and short shelf life, limiting their effectiveness and environmental friendliness.
Innovation Solution
A novel aqueous solution formulation of emamectin benzoate using anionic surfactants and natural high molecular surfactants, eliminating organic solvents and incorporating antifreezing, defoaming, and light stabilizing agents to enhance stability, efficacy, and environmental sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If organic solvents are used to dissolve emamectin benzoate, then solubility and formulation stability are improved, but environmental friendliness deteriorates and health hazards increase
Solution Approach 1:
The patent extracts and removes organic solvents from the pesticidal formulation system, replacing them with water as the sole solvent. This extraction of the harmful component (organic solvent) eliminates environmental pollution and health hazards while maintaining formulation stability through the use of surfactants and adjuvants that enable water-based dissolution of emamectin benzoate.
Solution Approach 2:
The patent changes the fundamental parameter of the solvent system from organic-based to water-based. By modifying the solvent type parameter and introducing specific surfactants and adjuvants, the formulation achieves both environmental friendliness and stability, resolving the contradiction between these two opposing requirements.
2Manufacturing precision
If particle size of pesticidal technical material is reduced, then efficacy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates dispersing agents and adjuvants in the formulation that pre-establish conditions for fine particle dispersion. These preliminary additives prevent particle aggregation and maintain small particle sizes throughout storage and application, achieving high efficacy without requiring complex post-manufacturing particle size control processes.
Solution Approach 2:
The patent introduces surfactants and dispersing agents as intermediary substances that mediate between the pesticidal technical material and water. These intermediaries enable the technical material to be dispersed at the molecular or fine particle level in water, achieving small effective particle sizes and high efficacy while simplifying manufacturing through straightforward mixing processes.
3Object-affected harmful factors
If water-based formulations are used, then environmental friendliness is improved, but solubility of oil-soluble pesticides deteriorates
Solution Approach 1:
The patent introduces surfactants and solubilizing adjuvants as intermediary substances that bridge the gap between water and oil-soluble pesticidal technical materials. These intermediaries have both hydrophilic and hydrophobic properties, enabling them to solubilize oil-soluble pesticides in water-based formulations, thereby achieving both environmental friendliness and adequate solubility.
Solution Approach 2:
The patent creates a composite water-based formulation system that combines water with specific surfactants, adjuvants, and emamectin benzoate. This composite material system leverages the properties of each component to achieve solubility of the oil-soluble pesticide in water while maintaining environmental friendliness, effectively resolving the solubility contradiction.
