In today's market, consumers increasingly expect products that not only perform well but also maintain their effects over time, whether in personal care, household products, or other functional formulations. To meet these demands, manufacturers use various technologies to improve the stability, retention, and controlled release of their active ingredients - compounds essential to enhancing product functionality.
Cross-linked polymers and resins of specific building blocks are widely used to stabilize and retain these active ingredients, protecting them from environmental factors like water, heat, or mechanical stress. This enhances the durability and effectiveness of the product over time. However, conventional cross-linking chemistries often carry environmental and health risks, including toxicity and poor biodegradability. Achieving the right balance between stability (crosslinking strength), sustainability, and biodegradability of the cross-linked polymers and resins is a major challenge.
As crosslinking density increases, the material generally becomes more resistant to breakdown by environmental factors, compromising biodegradability. Finding cross-linkers and building blocks that deliver long-lasting performance without compromising environmental safety or biodegradability is a key research focus in many fields, including bioplastics, coatings, and advanced material formulations.
We are looking for low-hazardous crosslinking systems that balance performance with biodegradability. Specifically, we are interested in cross-linkers and building blocks that, when combined with synthetic or natural building blocks, enable high crosslinking density while allowing the material to degrade naturally.
- Enzyme-based crosslinkers
- Modified existing cross-linkers to enhance biodegradability and control reactivity
- Oligosaccharides and polysaccharides that include a cross-linkable moiety
- Other bio-based polymers with adjustable degradation rates
- Researchers capable of developing tailored crosslinking systems
- Synergistic combinations of multiple cross-linkers for improved performance
- Controlled crosslinking process with predictable reactivity and manageable kinetics.
- Maintain biodegradability at high crosslinking density.
- Commercial cross-linkers must include their chemical structure in the proposal.
- Proposals should include a brief rationale explaining the potential effectiveness of the cross-linker.
- Perform well under moderate conditions (up to 100°C, 1 - 2 atm pressure).
- Accommodate a range of molecular weights (up to 5kDa).
- Scalable for industrial production (hundreds of metric tons).
- Materials derived from natural, biodegradable, or environmentally friendly sources.
- Researchers with expertise in developing tailored crosslinking solutions.
- Materials with preliminary safety data or assessments available.
- Materials that are/may be classified as substances of very high concern.
- Non-degradable solutions (e.g. siloxanes, certain PEG derivatives, acrylates, isocyanates).
- Highly reactive building blocks or cross-linkers prone to uncontrolled polymerization/crosslinking.
