Vegetable Oil Concentrate Formulation for Stable Agricultural Dispersions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural formulations, such as emulsifiable concentrates and suspensions concentrates, pose environmental and health risks due to the use of organic solvents and are not effective for water-sensitive active agents, while oil dispersions are not sufficiently stable.
Innovation Solution
A non-aqueous, emulsifiable concentrate formulation comprising polyethylene glycol esters of fatty acids, non-esterified vegetable oils, and phyllosilicates, with a specific ratio of components to achieve pourable and stable oil dispersions for agricultural active materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emulsifiable concentrates are used to achieve high concentration and good stability, then storage stability is improved, but environmental and health risks increase due to organic solvents
Solution Approach 1:
The patent changes the chemical composition parameters by replacing organic solvents with non-esterified vegetable oils as the liquid medium, while maintaining the emulsifiable concentrate formulation type. This substitution eliminates harmful organic solvents while preserving the formulation's stability and emulsifiability characteristics.
Solution Approach 2:
The patent uses non-esterified vegetable oils, which are biodegradable and environmentally friendly alternatives to persistent organic solvents. These natural oils provide the necessary solvating power while being less harmful to the environment and human health.
2Object-affected harmful factors
If suspensions concentrates are used to eliminate organic solvents, then environmental safety is improved, but effectiveness for water-sensitive active agents deteriorates
Solution Approach 1:
The patent creates a multi-functional formulation system where non-esterified vegetable oils serve multiple purposes: they act as a safe liquid medium, provide solvating power for water-sensitive active agents, and enable emulsification when mixed with water. This universal approach eliminates the need to choose between safety and effectiveness.
Solution Approach 2:
The patent combines non-esterified vegetable oils with surfactants and other formulation ingredients to create a composite emulsifiable concentrate system. This composite formulation provides both the environmental safety of water-based systems and the effectiveness of oil-based systems for water-sensitive active agents.
3Object-affected harmful factors
If oil dispersions are used to avoid organic solvents, then environmental risks are reduced, but storage stability deteriorates
Solution Approach 1:
The patent changes the formulation parameters by using non-esterified vegetable oils with specific chemical characteristics (natural triglycerides) rather than refined vegetable oil alkyl esters. This parameter change improves storage stability while maintaining the environmental benefits of using natural oils.
Solution Approach 2:
The patent develops a composite emulsifiable concentrate formulation that combines non-esterified vegetable oils with surfactants and stabilizers. This composite system provides both environmental safety and improved storage stability, overcoming the limitations of simple oil dispersions.
Applied Scientific Principles
