Oil-Based Suspension Concentrates Without Thickeners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-free suspension concentrates for agrochemicals require a thickener, which complicates production and reduces the availability of penetrants, and their crop tolerance and biological activity are not always sufficient when diluted with water.
Innovation Solution
Oil-based suspension concentrates composed of a room-temperature-solid compound, a penetrant, vegetable oil, nonionic or anionic surfactants, and optional additives, which are mixed and optionally ground to produce a stable formulation that enhances crop tolerance and biological activity without the need for thickeners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a thickener is added to water-free suspension concentrates, then the stability of the formulation is improved, but the production complexity increases and the penetrant availability decreases
Solution Approach 1:
The invention removes the thickener component from the formulation entirely, extracting the problematic element that caused production complexity while maintaining stability through an alternative mechanism based on vegetable oil and surfactant interactions
Solution Approach 2:
The invention changes the formulation parameters by using specific ratios of vegetable oil and surfactants, and controlling particle size through grinding, to achieve stability without requiring thickening agents
2Stability of the object's composition
If a thickener is added to water-free suspension concentrates, then the stability of the formulation is improved, but the penetrant availability decreases
Solution Approach 1:
The invention removes the thickener that was consuming penetrant, thereby freeing up the penetrant for its proper function while maintaining formulation stability through other means
Solution Approach 2:
The invention uses vegetable oil and surfactants as intermediary substances that mediate between the active ingredient and the environment, providing both stability and penetrant functionality without the need for thickeners
3Ease of operation
If conventional oil-based suspension concentrates are diluted with water, then the application is facilitated, but the crop tolerance decreases and biological activity is reduced
Solution Approach 1:
The invention changes the chemical parameters of the formulation by using specific compounds of formula (I') with particular functional groups and using natural vegetable oils, which maintain crop tolerance even when diluted with water during application
4Ease of operation
If conventional oil-based suspension concentrates are diluted with water, then the application is facilitated, but the biological activity is reduced
Solution Approach 1:
The invention optimizes the chemical parameters including using compounds with specific molecular structures (formula I'), appropriate surfactant types and ratios, and vegetable oil compositions that preserve biological activity through dilution while facilitating application
Solution Approach 2:
The invention creates a composite formulation system combining specific active compounds, vegetable oils, and surfactants that work synergistically to maintain biological activity even when diluted, while providing easy application properties
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 oil-based suspension concentrates exhibit improved crop tolerance and biological activity, with higher uptake of active substances by plants and reduced issues like creaming or flocculation upon dilution, allowing for higher activity or reduced active substance requirements.
