Sustainable natural cationic peptide disinfectant from moringa oleifera seeds
A novel, low-cost, non-toxic disinfectant formulated with cationic peptides extracted from Moringa Oleifera seeds. The water-soluble, thermally stable peptides demonstrate strong antiviral and antibacterial activity, offering a sustainable alternative to conventional quaternary ammonium disinfectants for water treatment and surface disinfection applications.
Overview
This solution offers a sustainable, low-cost disinfectant derived from cationic peptides naturally abundant in Moringa Oleifera seeds. Designed as a non-toxic alternative to conventional quaternary ammonium compounds, the formulation leverages naturally occurring bioactive peptides that are chemically and thermally stable up to 80°C and biocompatible with mammalian cells. The technology addresses growing demand for environmentally responsible disinfection in water treatment, healthcare, food safety, and surface sanitization markets.
Technical specifications
Key features and capabilities:
- Cationic peptides extracted from Moringa Oleifera seeds using a simple ion exchange process
- Demonstrated 8 log removal of E. coli and 7 log removal of MS2 bacteriophage in filtration testing
- Proven affinity toward SARS-CoV-2 and demonstrated antifungal efficacy
- Peptides are water-soluble and can be freeze-dried into a stable powder for easy distribution and storage
- Thermal stability up to 80°C enables versatile formulation options
- Biocompatible with mammalian cells, supporting safe handling and use
- Low production cost at approximately $0.30 per gram of peptide from feedstock alone
- Peptide water suspension designed to pass standard disinfection efficacy tests
Technology readiness level
The technology is at an early-to-mid stage of development. Proof-of-concept has been established through laboratory experiments and simulations confirming antiviral and antibacterial performance, with E. coli and MS2 removal validated across three to six individual filtration experiments and peptide extraction efficiency validated in triplicate experiments. Future validation will focus on optimizing the ion exchange procedure to maximize cationic peptide recovery and reduce production costs, evaluating disinfection efficacy and kinetics per ASTM E2274 standard protocols, and assessing long-term shelf stability of both freeze-dried powder and water suspension formulations at room temperature.
