Abstract
Background and Objective: Extensive application of silver nanoparticles encourages the need for synthesizing them through easy, efficient, green and eco-friendly techniques. Sonochemistry is one of the earliest approaches used to prepare nanosized particles. The objective of this study is to develop efficient facile simple green sonochemical route for the preparation of silver nanoparticles and its use in cosmetics. Methodology: About 20 mL of silver nanoparticles solution (0.1 M) having gelatin (1 wt.%) was sonicated under the irradiation of high-intensity ultrasound at room temperature for 15 min. The effect of irradiation time on the formation of silver nanoparticles has been investigated. The produced silver nanoparticles were characterized by means of UV-vis spectroscopy. Results: The UV-vis spectra confirmed the synthesis of silver nanoparticles by viewing typical peak between which give characteristic peak between 380-450 nm and increases with increasing irradiation times. Mechanism for Ag-NPs formation by the assistance of ultrasonic waves was described by pheromone of acoustic cavitation. Sonochemical synthesized Ag-NPs were found very stable and have enough preservation efficacy. Conclusion: It is concluded that the sonochemical-fabrication of silver nanoparticles seem to be suitable preservative in cosmetics and can be used for the production of other metals nanoparticles due to it is very simple and no toxic reagents are used.
