ACC Solid Compositions for Stable Water-Soluble Granules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formulations of 1-amino-1-cyclopropanecarboxylic acid (ACC) are not available in stable water-soluble granule or wettable powder forms, which are preferred by farmers for their storage stability and ease of application.
Innovation Solution
Formulations of ACC in water-soluble granules and wettable powders comprising specific fillers, wetting agents, binders, and organosilicon surfactants, such as lactose, non-ionic ethoxylated sorbitan, polyvinylpyrrolidone, and polyalkyleneoxide modified heptamethyltrisiloxane, to create stable and easily dissolvable solid compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ACC is formulated as liquid formulations, then storage and application benefits are achieved, but solid formulation requirements cannot be met
Solution Approach 1:
The patent transforms ACC from liquid to solid state by changing physical parameters through formulation with fillers, binders, and surfactants. This creates water-soluble granules and wettable powders that maintain chemical activity while providing solid formulation benefits for handling, transport, and storage.
Solution Approach 2:
The patent creates composite solid formulations by combining ACC with fillers (such as diatomaceous earth, silica, calcium carbonate), binders, and surfactants. These composite materials provide both the chemical activity of ACC and the physical properties of stable solid formulations that are easy to handle and transport.
2Ease of operation
If water-soluble granule formulations are used, then storage stability and ease of dissolving are improved, but stable ACC granule formulation does not exist
Solution Approach 1:
The patent uses fillers, binders, and surfactants as intermediary substances that enable ACC to form stable water-soluble granules. These intermediaries facilitate both storage stability and ease of dissolving by creating a matrix that protects ACC while allowing controlled release and dissolution in water.
Solution Approach 2:
The patent modifies the physical and chemical parameters of ACC through formulation to achieve both storage stability and water solubility. By controlling particle size, moisture content, and composition ratios of ingredients, the formulation achieves simultaneous optimization of stability and dissolvability.
3Reliability
If ACC is synthesized and used directly, then ethylene precursor function is achieved, but consistent thinning and coloration require specific formulations
Solution Approach 1:
The patent optimizes formulation parameters including pH control (using acids or bases), moisture content (5-20%), and ingredient ratios to ensure consistent ACC release and ethylene production. These parameter controls provide reliable thinning and coloration effects while maintaining manageable formulation complexity.
Solution Approach 2:
The patent develops composite formulations with specific ratios of ACC, fillers, binders, and surfactants that work synergistically to provide consistent agricultural effects. The composite structure ensures uniform distribution and controlled release of ACC, leading to reliable thinning and fruit coloration outcomes.
