ABSTRACT

Microemulsions are clear, stable, isotropic mixtures of oil, water and surfactant, frequently in combination with a cosurfactant. Since the discovery of microemulsions, they have attained increasing significance both in basic research and in industry. They are capable of solubilizing both hydrophilic and lipophilic ingredients with relatively higher encapsulation. There is growing recognition of their potential benefits in the field of cosmetic science in addition to the drug delivery. They are now being widely investigated for preparing personal care products with superior features such as having improved product efficiency, stability or appearance. These smart systems are suitable for perfuming purposes where minimum amount of organic solvents is required, such as for perfuming skin or hair. While microemulsions are used in several fields, this article focuses on the reported investigations for preservation and stabilization of fragrances in cosmetics, and pharmaceutical preparations.

Keywords: Perfume, Fragrance, Microemulsion, Surfactant.
