MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202631061577 A) filed by Dr. Sumita Banerjee; and Dr. Saikat Mukherjee, Imphal, Manipur, on May 14, for 'biodegradable sanitary napkin with tragacanth gum hydrogel and water hyacinth cellulose.'
Inventor(s) include Dr. Sumita Banerjee; and Dr. Saikat Mukherjee.
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 present relates to a fully biodegradable multi-layer sanitary napkin for menstrual hygiene management, comprising a bioactive Aloe barbadensis Miller superficial film, water hyacinth-derived cellulose acquisition and distribution layers, a Tragacanth gum (Gond Katira) ionically crosslinked hydrogel micro-bead absorbent core, a thermoplastic starch barrier layer, and a biodegradable release liner. The Aloe vera layer provides a skin-compatible, antimicrobial, and moisturizing interface, while the cellulose layers enable efficient fluid acquisition and lateral distribution. The absorbent core comprises swellable hydrogel micro-beads embedded in a cellulose matrix, configured to enhance fluid retention and reduce leakage and rewet characteristics. The barrier layer prevents fluid permeation toward the garment side while maintaining compostability. The sanitary napkin is substantially free from petroleum-derived synthetic polymers and is fully biodegradable. The invention further utilizes water hyacinth biomass as a renewable cellulose source, enabling sustainable waste valorisation and improved environmental compatibility."
