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

Abstract

Nano-perfumes refer to alcohol-free oil-in-water nanoemulsion perfumes containing fragrance. Due to its favorable properties, nanoperfumes 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 studies have addressed and developed this technology to date. In this review, we examine several essential elements of nano-perfumes in order to raise some relevant questions regarding the future of this technology. The discussion focused on the brief history of nanoperfumes, essential aspects of perfume, development of nanoemulsions in the cosmetics field, nano-perfume preparation methods, significant characteristics of nano-perfumes, and their problems and prospects.
