ABSTRACTS Calcium nanoparticles(CaNPs) using agro wastewater for antimicrobial cold cream formulation represents a promising approach in sustainable nanotechnology and cosmetic development.This study aims to create a sustainable method for synthesizing calcium nanoparticles from shea wastewater to develop antimicrobial cold cream formulations.The cold cream was formulated and evaluated physically by determing the texture,homogenicity,colour,washability,PH and the spreading time of analysis was recorded.The formulated cold cream was evaluated against selected microorganism(E.coli,P.aeroginosa,C.ablican, and S aureus).The biosynthesized CaNPs was charaterized using UV-visible spectroscopy analysis.Cloudy appearance was observed during the biosynthesis which show a positive sign that CaNPs synthesised effectively.All the concentration for the cold cream appeared creamy.The physical evaluation for all the concentration of the cold cream formulation show soft texture,cloudy colour and is homogenous.The ph of all the concentration ranges from(8.63 to 8.65),while the spreading time of all the concentration ranges from (2.8 to 5.2) seconds.The antibacterial and antifungal activities of biosynthesized CaNPs exhibit zone of inhibition of 50mm&100mm respectively.The UV-visible spectroscopy analysis of biosynthesized CaNPs exhibit an absorption peak of wavelength which ranges from 250nm to 700nm.In conclusion,This method provides a sustainable alternative to conventional synthesis techniques, potentially reducing the environmental impact associated with Shea waste processing.
