An improvement is described in the liquid crystal composition or the microemulsion composition more environmentally friendly, which is especially effective in the removal of oily and greasy soil and having an evidenced grease release effect, contains an anionic detergent, an esterified polyethoxyether nonionic surfactant, a hydrocarbon ingredient, a fatty acid and water which comprises the use of a water-insoluble odoriferous perfume as the essential hydrocarbon ingredient in a proportion sufficient to form either a dilute o/w microemulsion composition containing, by weight, 1% to 20% of an anionic detergent, 0.1 to 50% of a cosurfactant, 0.1% to 20% of the esterified polyethoxyether nonionic surfactant 0% to 2.5% of a fatty acid, 0.4% to 10% of perfume and the balance being water.
