Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aqueous formulations of (S)-(+)-abscisic acid salts face issues with color stability and precipitate formation, leading to inconsistent product quality and reduced efficacy, especially when mixed with other plant growth regulators like ethephon.
Innovation Solution
The development of color-stable and non-precipitating aqueous compositions containing the potassium salt of (S)-(+)-abscisic acid, incorporating the surfactant Atlox™ 4913 and color stabilizers sodium citrate and sodium acetate, which prevent discoloration and precipitate formation, allowing for stable mixing with ethephon and improved handling and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If aqueous formulations of (S)-(+)-abscisic acid salts are prepared, then the active ingredient can be applied to plants, but the formulations experience color changes from colorless to dark yellow or brown during storage
Solution Approach 1:
The patent introduces sodium citrate and sodium acetate as intermediary substances that mediate between the (S)-(+)-abscisic acid and the environment. These intermediaries act as color stabilizers that prevent the discoloration reaction without interfering with the biological activity of the active ingredient, thereby resolving the contradiction between maintaining color stability and preserving formulation quality
Solution Approach 2:
The patent modifies the chemical environment parameters by adding specific buffering agents (sodium citrate and sodium acetate) that change the pH and ionic composition of the formulation. This parameter change creates a stable chemical environment that prevents color degradation while maintaining the efficacy of the abscisic acid
2Adaptability or versatility
If aqueous formulations of (S)-(+)-abscisic acid salts are prepared, then the active ingredient can be applied to plants, but precipitates or particulate matter form during storage or when mixed with other plant growth regulators
Solution Approach 1:
The patent employs Atlox 4913 as a surfactant intermediary that facilitates mixing between (S)-(+)-abscisic acid and other plant growth regulators like ethephon. This surfactant acts as a mediator that prevents precipitation by reducing interfacial tension and maintaining homogeneous distribution of all components in the tank mixture
Solution Approach 2:
The patent creates a composite formulation system that combines (S)-(+)-abscisic acid, Atlox 4913 surfactant, and buffering agents into a stable aqueous composition. This composite material approach ensures that when mixed with other plant growth regulators, the formulation maintains homogeneity and prevents precipitate formation through the synergistic interaction of its components
3Quantity of substance
If racemic (R,S)-(±)-abscisic acid is used in compositions, then material availability is improved, but half of the material is inert requiring twice as much to be purchased, formulated, packaged, shipped, and applied
Solution Approach 1:
The patent extracts and isolates only the biologically active (S)-(+)-enantiomer of abscisic acid from the racemic mixture. By taking out only the effective component, the formulation achieves higher efficiency with half the quantity needed compared to using racemic mixtures, while still maintaining ease of manufacture through targeted synthesis or separation processes
