Polyglycerol Ester Carriers for Microbiological Ingredient Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biological plant protection and biostimulant formulations face challenges with the lower efficacy and stability of microbiological active ingredients due to insufficient survival capacity during storage and application, leading to reduced bioavailability and effectiveness on plants or in soils.
Innovation Solution
The use of polyglycerol esters and emulsifiers, such as sorbitan fatty acid esters and ethoxylated sorbitan fatty acid esters, as carriers for microbiological active ingredients, which enhance storage stability, adhesion, and reduce spray drift, while being biodegradable and sustainably produced.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional carriers are used for microbiological active ingredients, then the formulations can be applied, but the storage stability and survival capacity of microorganisms deteriorate
Solution Approach 1:
The patent changes the chemical and physical parameters of the carrier system by using polyglycerol esters with specific molecular weights and fatty acid compositions, along with emulsifiers having particular HLB values. These parameter changes create an optimized microenvironment that maintains microorganism viability during storage while allowing effective application.
Solution Approach 2:
The invention employs composite carrier systems combining polyglycerol esters with specific emulsifiers (sorbitan fatty acid esters and ethoxylated sorbitan fatty acid esters). This composite approach creates synergistic effects where the carrier matrix provides structural stability while the emulsifier interface protects microorganism cells, resolving the contradiction between storage stability and microorganism survival.
2Object-affected harmful factors
If microbiological active ingredients are used in biological plant protection products, then chemical pesticide residues are reduced, but the efficacy and bioavailability are lower
Solution Approach 1:
The polyglycerol ester carrier acts as an intermediary between the microbiological active ingredient and the plant target. It enhances the delivery and bioavailability of microorganisms to the plant surface and interior, thereby improving efficacy without requiring chemical pesticides. The carrier facilitates microorganism attachment and survival in the plant microenvironment.
3Area of stationary object
If spray formulations are applied to plants, then coverage is achieved, but spray drift occurs reducing precision
Solution Approach 1:
The patent modifies the surface tension and viscosity parameters of the spray formulation through the selective use of polyglycerol esters and emulsifiers. These parameter changes increase droplet adhesion to plant surfaces and reduce aerosolization, thereby minimizing spray drift while maintaining effective coverage. The specific HLB values of emulsifiers are optimized to control droplet behavior during application.
