Innovation Solution
A stable non-aqueous agrochemical formulation comprising a Triketone herbicide, additional herbicides, vegetable oils, and a surfactant system with ionic phosphated Tristyrylphenol alkoxylate and non-ionic Tristyrylphenol alkoxylate, enhancing chemical and dispersion stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If regular organic solvents are used in herbicide formulations, then chemical stability of the herbicide is improved, but environmental pollution and flammability increase
Solution Approach 1:
The patent changes the fundamental parameter of the solvent system from conventional organic solvents to vegetable oil-based solvents. This parameter change maintains the chemical stability required for herbicide formulation while eliminating the harmful environmental effects and flammability associated with traditional organic solvents. The vegetable oil base provides a stable, non-flammable, and environmentally benign alternative.
Solution Approach 2:
The patent employs vegetable oils as a renewable, biodegradable solvent system that can be readily degraded in the environment. This replaces persistent organic solvents with a natural, short-lived carrier that breaks down harmlessly, reducing environmental accumulation and pollution while maintaining formulation stability during the product's service life.
2Object-affected harmful factors
If Triketone herbicides are formulated in aqueous systems, then environmental friendliness is improved, but chemical stability and dispersion stability deteriorate
Solution Approach 1:
The patent introduces vegetable oil as an intermediary solvent system that bridges the gap between aqueous environmental friendliness and chemical stability requirements. The vegetable oil base acts as a mediator that provides the hydrophobic environment needed for Triketone stability while being inherently more environmentally benign than conventional organic solvents, thus resolving the contradiction between stability and environmental friendliness.
3Object-affected harmful factors
If Triketone herbicides are formulated in aqueous systems, then environmental friendliness is improved, but dispersion stability after dilution deteriorates
Solution Approach 1:
The patent changes the solvent parameter from water-based to vegetable oil-based, which fundamentally alters the dispersion characteristics. The vegetable oil matrix provides better compatibility with Triketone herbicides, maintaining uniform dispersion stability even after dilution with water in the field, while preserving the environmental advantages of a natural oil base rather than synthetic solvents.
4Stability of the object's composition
If conventional surfactant systems are used, then formulation stability is improved, but environmental impact increases
Solution Approach 1:
The patent applies local quality by selecting specific biodegradable surfactants that are tailored for use in vegetable oil-based formulations. These surfactants provide the necessary stabilization and emulsification properties locally within the oil matrix, ensuring formulation stability while maintaining overall environmental compatibility through their biodegradable nature and lower toxicity profiles.
