MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641057135 A) filed by Agni College Of Technology, Chennai, Tamil Nadu, on May 5, for 'an eco-friendly supramolecular hydrogel composition based on chitosan and neem seed oil for sustainable pest control.'
Inventor(s) include Arunodhaya N; Veda Valli M; Surya G; and Vigash S.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The overuse of chemical pesticides is rapidly increasing environmental and human health risks. Thus, it is urgently needed to develop safer and more sustainable alternative approaches for pesticide use in agriculture. In this study, we developed a bio-pesticide using a blend of chitosan, Cetyl Trimethyl Ammonium Bromide (CTAB), Laponite clay and neem oil. The biodegradable polymer chitosan was used as a polymeric matrix for its excellent film forming properties, biocompatibility and other functional features. The addition of CTAB (cationic surfactant) was to increase the interfacial interaction between the formulated product and the target surfaces for better dispersion and efficacy. Laponite clay was used as a stabilizer and carrier to improve the stability of the bio-pesticide formulation, adsorption capacity and to promote the slow release of active ingredients. The bio-pesticide formulation developed in this study was fortified with neem oil to ensure the bio-activity of the formulated product."
