BIOSYNTHESIS OF SNWWCANPS
Abstract
The increasing demand for sustainable and effective antimicrobial agents in
cosmetics has led to the exploration of natural resources for nanoparticle synthesis. This
study focuses on the biosynthesis of calcium nanoparticles using shea waste, aiming to
develop an antimicrobial cold cream formulation. The synthesized nanoparticles were
subjected to a green synthesis process by mixing shea waste with distilled water at varying
concentrations (10 µg/ml to 100 µg/ml). The synthesized calcium nanoparticles were
characterized using UV-visible spectroscopy, with absorbance measured across the UV
and visible light spectrum (250 nm to 700 nm). The cold cream formulation was evaluated
for physical properties, including pH, homogeneity, spreadability, washability, and
texture. Antimicrobial efficacy was tested against common pathogens (Aspergillus flavus,
Staphylococcus aureus etc). The results indicated successful biosynthesis of calcium
nanoparticles, which demonstrated significant antimicrobial activity against the tested
pathogens. The physical evaluations of the cold cream formulation showed acceptable
characteristics, making it suitable for cosmetic applications. The green synthesis of
calcium carbonate nanoparticles from shea waste presents a promising avenue for
developing antimicrobial cold creams. This approach not only enhances the antimicrobial
properties of cosmetic formulations but also offers a sustainable alternative to traditional
synthesis methods, reducing the environmental impact associated with shea
processing. The findings support the potential of utilizing agricultural waste in
nanotechnology and cosmetic development.
