First claim
Opening claim text (preview).
The invention claimed is: 1. A surfactant having the following structure (I): where m is a value in a range of 3 to 10, n is a value in a range of 5 to 20 and z is a value in a range of 5 to 30. 2. The surfactant of claim 1 , further characterized by m being 5, n being in a range of 9 to 15 and z being in a range of 5 to 25. 3. The surfactant of claim 1 , further characterize by the ratio of n to z being one or less. 4. The surfactant of claim 1 , further characterized by m being 5, n being a value in a range of 5 to 9 and z being a value in a range of 10 to 25. 5. A method of using the surfactant of any previous claim, the method comprising placing a detergent composition containing the surfactant in an automatic dishwasher. 6. The surfactant of claim 1 , further characterized by m being 5, n being a value in a range of 10 to 15 and z being a value in a range of 10 to 25.
