Green formulation of Plant - Based Mobile Device Sanitizers : A study on the Antimicrobial Efficacy of Turmeric , Neem and Peepal Extracts

Abstract

The present study deals with the development and assessment of a herbal mobile cleaner spray incorporating plant extracts of Neem (Azadirachta indica), Turmeric (Curcuma longa) and Peepal (Ficus religiosa) as natural alternatives to synthetic sanitizing agents. Mobile surface contamination with pathogenic microbes has been widely documented, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida spp., creating significant public health concerns. These medicinal plants are well known for their broad-spectrum antimicrobial, anti-inflammatory, and skin-protective properties. The herbal extracts were prepared using ethanol and Distilled water, and then used to formulate a cleaning spray. The products were tested for germ-killing activity through zone of inhibition and mobile surface swab tests. The formulated sanitizer was evaluated for antimicrobial activity, physical stability, sensory characteristics such as texture and fragrance, and overall safety for topical use. Their safety was also evaluated by checking pH, colour, odour, irritation effects, and stability over time. Recent studies demonstrate that plant-based formulations can significantly reduce bacterial contamination on personal devices while being safer and more eco-friendly than traditional chemical disinfectants. The results indicated that these natural formulations show significant antimicrobial efficacy along with good skin tolerance, suggesting that the herbal mobile sanitizer is a safe, eco-friendly, and effective alternative for routine mobile cleaning and infection control.
