Aqfresh additive for reducing organic compound permeation in polypropylene
AqFresh is a supramolecular host additive designed to reduce the permeation of organic compounds, such as odours and volatile organic compounds, in polypropylene by complexing with these molecules. This technology is targeted for applications in polyethylene packaging to improve product integrity.
Overview
AqFresh is an innovative supramolecular host additive developed to enhance the performance of polypropylene by reducing the permeation of organic compounds. By integrating AqFresh into a polyethylene-based masterbatch, it can significantly diminish the release of odours and volatile organic compounds, thus improving the overall integrity and usability of polyethylene packaging products. The technology is particularly beneficial for applications requiring high containment of chemicals, such as solvents and alcohols, in packaging solutions.
Technical specifications
Key features:
- AqFresh can be incorporated into polyethylene products at concentrations of 0.5% to 1.5%.
- Demonstrated significant reduction in product odour compared to control samples.
- Capable of complexing with a wide range of small organic molecules, enhancing the barrier properties of polyethylene.
- Suitable for use in various PE packaging applications, ensuring reduced chemical permeation and improved product quality.
Technology readiness level
This technology is at TRL 5, indicating that it has been tested in a relevant environment. Future validation steps include building a packaging prototype, conducting permeation tests under simulated conditions, and ensuring mechanical property compliance. The upcoming year-long study aims to demonstrate scalability and obtain necessary regulatory approvals.
About Aqdot Limited
Aqdot is a supramolecular chemistry company headquartered in Cambridge, England, that develops and licenses proprietary encapsulation technology. The company's core platform, known as AqFresh, is based on patented, barrel-shaped molecules called cucurbiturils. These molecules feature a hydrophobic cavity and polar portals, enabling them to capture, hold, and release a wide range of molecules. By utilizing this unique structural capability, the technology provides a versatile solution for the rapid, continuous, and effective removal of odors and volatile organic compounds (VOCs). The technology is designed to be non-biocidal, non-toxic, and fragrance-free, functioning across various states, including liquids, solids, coatings, and textiles.
The company focuses on helping manufacturers improve indoor air quality, human health, and sustainable production processes. Aqdot’s solutions are currently applied across multiple sectors, including home and personal care, automotive interiors, hygiene, and industrial applications. Through strategic partnerships, such as with Clariant for the laundry and automatic dishwashing markets, Aqdot provides drop-in, ready-to-use chemical solutions that integrate into existing manufacturing processes. The technology has been validated in industrial trials and is utilized by customers to enhance product effectiveness and differentiate brands while addressing common challenges like malodors and environmental pollutants.
