  • Method of washing a surface with a surfactant composition
    Patent number: 7503333
    Abstract: A method of washing a surface includes the step of providing a cleaning formulation including a surfactant composition including a first surfactant, a second surfactant, and a polyalkylene glycol. The first surfactant has the general formula: R1—O-(A)mH. R1 is an aliphatic hydrocarbon having from 8 to 11 carbon atoms, A is an alkyleneoxy group having from 2 to 5 carbon atoms, and m is a positive number. The second surfactant has the general formula: R2—O-(B)nH. R2 is an aliphatic hydrocarbon having from 12 to 14 carbon atoms, B is an alkyleneoxy group having from 2 to 5 carbon atoms, and n is a positive number. The polyalkylene glycol is present in an amount of from 3 to 20 parts by weight. The method also includes providing a rinse formulation, applying the cleaning formulation to the surface, and applying the rinse formulation to the surface.
