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.
