HARD-SURFACE CLEANING COMPOSITIONS COMPRISING SOLVENT, SURFACTANT AND LIPASE

摘要

Selected combinations of particular solvents and surfactant are compatible with lipolytic enzymes in that after a first application of the compositions of the present invention the cleaning effort required to remove soils in subsequent cleaning cycles is reduced. The invention provides a cleaning composition for hard surfaces which comprises: a) a solvent having at least one alcoholic hydroxyl group and at most one ether linkage, b) a surfactant, and, c) a lipolytic enzyme. It is believed that the selected solvents interact with the enzyme to somehow prevent the surfactant from interfering with the activity of the enzyme, in a synergistic interaction in that the addition of either enzyme or solvent to a surfactant increases cleaning effort as compared with surfactant alone whereas the addition of both solvent and surfactant reduces cleaning effort as compared with surfactant alone.
