The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an eco-friendly antifungal composition comprising oyster shell-derived calcium carbonate and neem-based bioactive components for use in dental, dermatological, and cosmetic applications. The composition is formulated as a multifunctional powder exhibiting antifungal, antibacterial, and anti-inflammatory properties. The oyster shell component provides a calcium carbonate-rich matrix that maintains an alkaline environment unfavorable for fungal growth, while the neem component contributes phytochemicals that disrupt fungal cell membranes and inhibit biofilm formation. The invention demonstrates enhanced antifungal efficacy, particularly against Candida albicans, through a synergistic dual mechanism of action. The composition is biodegradable, non-toxic, and cost-effective, utilizing waste oyster shells as a sustainable resource. The invention addresses limitations associated with synthetic antifungal agents by providing a natural, safe, and environmentally friendly alternative with broad-spectrum antimicrobial activity suitable for healthcare and personal care applications."
