Water-Insoluble Active Compound Stabilization via Oil-Modified Acid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aqueous compositions of water-insoluble active organic compounds, such as biocides and fungicides, typically require emulsifiers or surfactants to form stable systems, but these are prone to wash-off during rain, reducing their effectiveness on surfaces like coatings and wood.
Innovation Solution
A stable aqueous composition is achieved by combining a water-insoluble active organic compound with a water-insoluble oil-modified alpha-beta unsaturated carboxylic acid, such as linseed oil-modified maleic acid, without the need for emulsifiers or surfactants, creating a fine droplet or particle distribution that is water-resistant and effective against microbiological attack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If emulsifiers or surfactants are used to form stable aqueous compositions of water-insoluble active organic compounds, then stability of the composition is improved, but resistance to wash-off during rainfall deteriorates
Solution Approach 1:
The invention changes the chemical parameters of the system by replacing conventional emulsifiers/surfactants with a water-insoluble oil-modified alpha-beta unsaturated carboxylic acid. This chemical substitution fundamentally alters how the active organic compound is stabilized in aqueous medium, transitioning from surfactant-based stabilization to a different chemical mechanism that provides both stability and water resistance simultaneously.
Solution Approach 2:
The invention creates a composite system by combining the water-insoluble active organic compound with the water-insoluble oil-modified alpha-beta unsaturated carboxylic acid. This composite approach allows the two components to work synergistically, where the carboxylic acid modification provides both the stabilization mechanism and the water-resistant properties that conventional single-component surfactants cannot achieve.
2Reliability
If IPBC is used to provide biocidal effectiveness against fungi, then anti-fungal protection is improved, but yellowing effect under UV radiation worsens
Solution Approach 1:
The oil-modified alpha-beta unsaturated carboxylic acid acts as an intermediary substance between the IPBC active compound and the UV radiation environment. This intermediary provides a protective interface that allows IPBC to maintain its biocidal function while preventing direct UV interaction that causes yellowing, thus decoupling the biocidal effectiveness from the harmful yellowing effect.
Solution Approach 2:
The invention converts the potential harm of UV exposure into a benefit by using the oil-modified carboxylic acid system. The oil modification creates a matrix that actually protects the IPBC from UV degradation, transforming what would be a harmful UV interaction into a protected state where IPBC maintains effectiveness without yellowing.
3Ease of manufacture
If conventional emulsifier-based formulations are used, then ease of formulation is improved, but water resistance of the delivered active deteriorates
Solution Approach 1:
The invention changes the formulation parameters by eliminating the need for conventional emulsifiers and using instead the water-insoluble oil-modified alpha-beta unsaturated carboxylic acid. This parameter change simplifies the formulation system while simultaneously providing the water resistance property that conventional emulsifier-based systems lack.
