A pourable low-foaming alkoxylated amine oxide surfactant concentrate and method for making the concentrate are disclosed. The amine oxide concentrate has novel properties in that it is both highly concentrated and pourable at ambient temperatures. The amine oxides of the amine oxide concentrate include from about 3.5-30 moles of alkoxylated units and may be based on ether and/or fatty tertiary amine precursors. The low foaming properties and pourability of the amine oxide surfactant concentrate make the invention ideal for low-foam applications and for use in surfactant formulations. |
