Abstract

An improvement is described in microemulsion compositions which are more friendly to the environment and contain an anionic sulfate surfactant, an esterfied polyethoxyether surfactant, a cosurfactant, at least one hydrocarbon, and water which can comprise the use of a water-insoluble odoriferous perfume as the essential hydrocarbon in a proportion sufficient to form a dilute o/w microemulsion composition preferably containing, by weight, 0.1% to 8% of an anionic sulfate surfactant, 1% to 50% of a cosurfactant, 1% to 20% of an ethoxylated glycerol type compound, 0.4% to 20% of perfume and the balance being water.
