Nano-Perfumes As A Fragrance Carrier: Their Brief History, Essential Aspects, Development, Preparation Methods, Characteristics, And Future Perspectives

Nano-perfume is an alcohol-free perfume in the form of oil-in-water nanoemulsions containing fragrance. Due to its favorable properties, nano-perfume may appeal to a broader client base, including children and individuals with sensitive skin. This technology can provide an alternative solution to the low permanence of fragrances by eliminating ethanol and decreasing the amount of surfactant, co-surfactant, and solvents used in the formulation. However, relatively few researchers have studied and developed this technology to date. In this review, we examine several essential elements of nano-perfume, therefore it is hoped that relevant questions will be raised regarding the future of this technology. The discussion is focused on the definition and composition of perfume, the notion of "notes" in fragrances products, nanotechnology in the cosmetics industry, significant characteristics of nano-perfume, as well as problems and prospects.
