Abstract: A transparent, aqueous perfume micro-emulsion composition is provided that includes a fragrance material, a solvo-surfactant, an ionic surfactant, optionally a non-ionic surfactant, and water. The solvo-surfactant comprises at least one monoalkyl glycerol ether having a general formula of R—O—CH2—CH(OH)—CH2OH, wherein R is selected from the group consisting of C8 to C12 unbranched alkyls and C6 to C7 unbranched terminal alkenyls. The aqueous perfume microemulsions are stable and may be used in their concentrated form or diluted with water depending on the end use application.
