Nanoemulsions as a Form of Perfumery Products

Abstract

Alcohol-based perfumes, e.g., eau de parfum, eau de toilette, eau de cologne or au fraiche, are the most common type of fragrance products available on the market. There are also alcohol-free fragrance products, mainly in the form of solid or oil perfume. From the consumers’ point of view, such perfumery products are of interest; therefore, looking for new solutions is still interesting. Nanoemulsions are liquid, kinetically stable colloidal dispersions, consisting of an aqueous phase, an oil phase and a surfactant, with or without a co-surfactant. They are transparent, not greasy, easy to spray and spread. Additionally, they show capacity to protect fragrances from oxidation. The development of a water-based perfumes in the form of stable nanoemulsions containing fragrance compositions (in the range of 5–15%), stabilized by nonionic surfactants, allows to create safe products for a wider group of consumers, including children, adolescents and people with sensitive skin. In this article, an application of nanoemulsions as a potential form of perfumery products were described.
