Reaction products of an optionally alkoxylated alcohol, a polyalkylene alcohol and a linker can be used in various applications such as defoamers. Methods of making the reaction products and defoamer compositions including the reaction products, and methods of using the reaction products to reduce or prevent foam in a composition are also disclosed. The reaction products can be used with an organic solvent or without an organic solvent to provide low VOC compositions.

Reaction products and use of same in defoamer compositions and methods for defoaming

A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor.
