Abstract:
A liquid cleaning composition which contains a lower aqueous phase and an upper oily phase, wherein the liquid cleaning composition comprises approximately by weight:(a) 0. 1% to 10% of an ethoxylated nonionic surfactant, wherein 80% to 100% of said nonionic being in said upper oil phase and 0 to 20% of said nonionic surfactant being in said lower aqueous phase; or distributed between said upper and lower phase according to partition coefficient of the nonionic surfactant; (b) 0.1% to 5% of a second surfactant which is a zwitterionic surfactant, wherein 90% to 100% of said second surfactant being in said lower aqueous phase and 0 to 10% of said second surfactant being in said upper oily phase; or distributed between said upper and lower phase according to partition coefficient of said second surfactant; (c) 0.1% to 10% of a water insoluble organic compound wherein at least 98% of said water insoluble organic compound is contained in said upper oily phase; (d) 0.05% to 2% of a perfume, wherein at least 98% of said perfume is contained in said upper oily phase; or distributed between said upper and lower phase according to partition coefficient of said perfume; (e) 0.1% to 10% of a solubilizing agent, wherein 60% to 90% of said solubilizing agent being in said lower aqueous phase and 10% to 40% of said solubilizing agent being in said upper oily phase; (f) 0.1% to 20% of a glycol ether, wherein 80% to 100% of said glycol ether being in said upper oily phase and 0 to 20% of said glycol ether being in said lower phase; (g) 0 to 3% of an acid selected from the group consisting of an organic acid and an inorganic acid and mixtures thereof, wherein at least 90% of said acid being in said lower aqueous phase; and (h) 60% to 99.5% of water, said water being in said lower aqueous phase.
