PATENT No.: US12,071,490 B2 – Antimicrobial Polymer

Description of the Patent:

The present invention is a process to produce Z-Chitosan to provide consistent and long-lasting antimicrobial, antiviral, antibacterial, antifungal, anti-spore, and anti-odor character- istics, the process comprises steps of preparing a liquid active agent comprising 50 ppm to 5,000 ppm aqueous solution of each of a Chitosan group, a herbal extract group, and a catalyst group using an emulsion crosslinking method for 24 to 144 hours at normal room conditions; preparing a powder form of the active agent by drying the liquid active agent; encapsulating the powder form of the active agent within a plastic, a polymer, a fabric to make a masterbatch of the product, and finally blending 1 to 10 percent of the masterbatch with a batch of plastic, polymer, or fabric to make an antimicrobial product, whereby the product shows antimicrobial and self-sanitizing efficacy for contact time between 2 hours to 24 hours and maintains its antimicrobial efficacy in the scale of years in different environment conditions.

What makes our patented antimicrobial polymer so unique?

Biopolymer Chitotec Polymer distinguishes itself not only by its remarkable ability to seamlessly incorporate organic compounds into a polymeric structure but also through its inherent biodegradability and potent antimicrobial properties.

Traditionally, creating polymers with embedded organic substances has been a challenge. The high temperatures often required during polymerization can lead to the degradation and deactivation of these sensitive compounds. Our innovation has overcome this limitation, allowing us to preserve the original properties of Z-Chitosan within the polymer matrix.

This successful integration of Z-Chitosan into Chitotec empowers the biopolymer with significant antimicrobial capabilities. Z-Chitosan’s inherent ability to disrupt the cell walls of bacteria and fungi makes Chitotec an effective tool in combating harmful microorganisms.

Furthermore, Chitotec’s biodegradability offers a sustainable advantage over many traditional polymers. It breaks down naturally over time, reducing environmental impact and promoting a circular economy.

The combination of organic compound integration, biodegradability, and antimicrobial action positions Chitotec as a truly unique and versatile biopolymer with a wide range of potential applications in fields where both effectiveness and sustainability are crucial.

Here you have the process resumed in 4 steps:

  1. Creating a liquid active agent: This is done by combining a chitosan solution, herbal extracts, and a catalyst in specific concentrations. The mixture undergoes emulsion crosslinking under normal room conditions for a period ranging from 24 to 144 hours.
  2. Drying the active agent: The liquid active agent is dried to produce a powder.
  3. Encapsulation: The powdered active agent is then encapsulated within a plastic, polymer, or fabric to create a masterbatch.
  4. Blending: Finally, a small percentage (1-10%) of this masterbatch is blended with the main batch of plastic,polymer, or fabric to produce the final antimicrobial product.

The resulting product demonstrates antimicrobial and self-sanitizing properties, effective within 2 to 24 hours of contact, and maintains these properties for years, even under varying environmental conditions.
