In nanotechnology, nano materials are created at molecular level which exhibit qualities quite different from the bulk material. Bulk silver, when reduced to nano-level, shows remarkable changes in the properties making it more environments friendly and useful. Nano silver exhibits unique physical and chemical properties compared to “conventional” silver (e.g., macro scale “bulk” silver). Nano silver of different shapes can be synthesized using various synthesis processes. such as electron irradiation, laser ablation, chemical reduction, biological artificial methods, photochemical methods and microwave processing. In present work firstly we prepared the ethanolic extract of Aloevera and Silver nanoparticles (AgNPs) were synthesized by bio reduction of Ag+ ions (from silver nitrate AgNO3), using aqueous or ethanolic Aloe vera extracts as reducing, stabilizing, and size control agent and characterized by microscopy and UV. With prepared silver nano particles cold cream was prepared and compared physicochemical parameters i.e viscosity, globule size ,spredability with the control cold cream which is prepared without silver nano particles
