IPBC Preservative Composition Stability Across pH Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preservative compositions for personal care and industrial applications often require specific formulations to meet safety and stability criteria, and many are not formaldehyde-free or paraben-free, lacking broad compatibility and stability across varying temperatures and pH levels.
Innovation Solution
A preservative composition consisting of 3-iodo-2-propynylbutyl carbamate (IPBC) in 1,3-butylene glycol, used at 9-11% IPBC and 89-91% glycol, which is effective, safe, and stable across a broad pH range, ensuring compatibility with various raw materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional preservative compositions are used, then microorganism growth inhibition is achieved, but formaldehyde and paraben contaminants are present, and stability across varying temperatures and pH levels is compromised
Solution Approach 1:
The patent removes harmful formaldehyde and paraben components from the preservative formulation while retaining effective microorganism growth inhibition through alternative safe preservative agents and synergistic combinations
Solution Approach 2:
The invention modifies the chemical composition parameters by substituting conventional preservatives with safer alternatives and adjusting the formulation to achieve stability across broad temperature and pH ranges without compromising antimicrobial efficacy
2Reliability
If preservative compositions are formulated for specific applications, then effectiveness is improved, but compatibility with various raw materials and stability across different conditions deteriorates
Solution Approach 1:
The patent develops a universal preservative composition that can be effectively applied across multiple personal care and industrial formulations, maintaining stability and compatibility with diverse raw materials including emulsifiers, surfactants, and active ingredients through careful formulation design
