MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133959 A) filed by V. Ayyappan, Tenkasi, Tamil Nadu, on Dec. 31, 2025, for 'biodegradable toothbrush comprising natural fiber bristles and antimicrobial root handle.'
Inventor(s) include P. Nancy; V. Ayyappan; E. A. Mohamed Ali; T. Arun Srinivas; and M. Rajkumar.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a novel biodegradable toothbrush manufactured from a handle made from Ficus Benghalensis (Banyan tree) root and bristles derived from processed coconut coir fibers. This product is I 00% biodegradable, 10 achieving complete decomposition within 6-12 months in natural environments, thereby offering a sustainable solution to the global plastic toothbrush crisis (eliminating 18-20 grams of plastic waste per unit). The invention leverages the inherent phytochemicals (tannins, flavonoids) in the root and lauric acid derivatives in the coir. to provide natural antimicrobial properties, reducing 15 bacterial colonization by 50-85% compared to synthetic alternatives. The handle is sustainably sourced and finished with natural oil for water resistance, while the coir bristles are mechanically softened for gum safety. The toothbrush is assembled using natural plant-based adhesives in a Micro-Hole Insertion method, yielding high bristle density (2000-3000+ bristles). The innovation achieves an 20 88% reduction in carbon footprint and is cost-competitive (production cost 8-IS INR), integrating traditional wisdom with modern design for superior oral health and environmental responsibility."
