Abstract
An improvement is described in the liquid crystal composition or the microemulsion compositions, which is especially effective in the removal of oily and greasy soil and having an evidenced grease release effect, contains an anionic detergent, an ethoxylated glycerol type compound, a hydrocarbon ingredient, at least one cosurfactant, and water which comprises the use of a water-insoluble odoriferous perfume as the essential hydrocarbon ingredient in a proportion sufficient to form a dilute o/w microemulsion composition containing, by weight, 1% to 20% of an anionic surfactant, 0.1 to 50% of at least one cosurfactant, 0.1% to 20% of an ethoxylated glycerol type compound, 0.4% to 10% of perfume and the balance being water.
