[0072] The foam control performance of Examples 1-15 versus a comparative example, Comparative Example 1, is reported in TABLE 2. The foam control performance of each of Examples 1-15 was measured using a rotating cylinder test as described below.

[0073] Each rotating cylinder test for the inventive examples included adding 0.0025 parts of the respective foam control composition of Examples 1-15 to 100 parts of a commercially available liquid detergent, which included both a non-ionic surfactant and an anionic surfactant, to form a detergent solution. Then 1.8 parts of each detergent solution was added to 300 parts of distilled water to form a mixture. The resulting mixtures were each then added separately to a cylinder and tested. Before each rotating cylinder test was performed, the cylinder was sealed. After sealing the cylinder, the cylinder was rotated for 12 minutes at 30 rpm. Comparative Example 1 was a mixture comprising 1.8 parts of the commercially available liquid detergent and 300 parts of distilled water. Comparative Example 1 did not include any of the materials of Examples 1-15. Comparative Example 1 was also tested using the rotating cylinder test described above.

[0074] After rotating the cylinder as described above, the foam height was immediately measured for the mixtures that included the compositions of Examples 1-15 and Comparative Example 1 and the foam height was recorded in mm.

[0075] The lower the foam height reported in TABLE 2, the better the foam control performance. As illustrated in TABLE 2, none of the foam control compositions of Examples 1-15 increased the height of the foam produced after conducting the rotating cylinder test versus Comparative Example 1. In fact, the foam control compositions of Examples 1-11, 13, and 15 showed a decrease in the height of the foam produced versus Comparative Example 1 and each of these examples exhibited good to very good foam control.

[0076] From the foregoing detailed description, it will be apparent that various modifications, additions, and other alternative embodiments are possible without departing from the true scope and spirit. The embodiments discussed herein were chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to use the invention in various embodiments and with various modifications as are suited to the particular use contemplated.
