Aqueous Dianhydrohexitol Packaging to Prevent Degradation and Caking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for packaging dianhydrohexitols, particularly isosorbide, are complex, expensive, and unsuitable for large quantities, leading to chemical degradation and caking issues, especially in food and pharmaceutical applications where minimal antioxidants are required.
Innovation Solution
Packaging dianhydrohexitols in the form of an aqueous solution using a single layer of polyolefin-based material with minimal or no antioxidants, maintaining a dry matter content between 40% and 95%, and ensuring stability through a simple, cost-effective process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If dianhydrohexitol is packaged in solid form using gas-impermeable packaging materials under reduced oxygen and nitrogen pressure, then chemical stability is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent changes the physical state parameter of dianhydrohexitol from solid to aqueous solution form. This parameter change fundamentally alters the packaging requirements, allowing the use of simple polyethylene bags without complex gas-impermeable layers or reduced pressure conditions, while maintaining chemical stability during storage and transport.
Solution Approach 2:
The patent employs inexpensive, single-use polyethylene packaging bags instead of complex, expensive gas-impermeable packaging systems. The simple polyethylene material, typically used for short-term storage, effectively protects aqueous dianhydrohexitol solutions without requiring sophisticated packaging infrastructure.
2Ease of manufacture
If dianhydrohexitol is packaged in solid form using traditional polyethylene packaging, then packaging simplicity is improved, but chemical degradation occurs leading to formic acid formation
Solution Approach 1:
The patent changes the physical state parameter of dianhydrohexitol from solid to aqueous solution form. This parameter change fundamentally alters the packaging requirements, allowing the use of simple polyethylene bags without complex gas-impermeable layers or reduced pressure conditions, while maintaining chemical stability during storage and transport.
3Stability of the object's composition
If antioxidants are added to packaging material to improve dianhydrohexitol stability, then chemical stability is improved, but antioxidant content increases which is problematic for food and pharmaceutical applications
Solution Approach 1:
The patent changes the physical state parameter of dianhydrohexitol from solid to aqueous solution form and adjusts the water content parameter. This parameter change eliminates the need for antioxidants in packaging material, as the aqueous solution form inherently maintains stability without requiring additional antioxidant substances, thus meeting food and pharmaceutical application requirements.
4Productivity
If solid dianhydrohexitol is packaged in large quantities, then productivity is improved, but caking issues occur during storage
Solution Approach 1:
The patent changes the physical state parameter of dianhydrohexitol from solid to aqueous solution form. This parameter change eliminates caking issues entirely, as the liquid solution maintains uniform composition and flow properties during storage and transport, allowing efficient packaging of large quantities without physical degradation.
