Abstract: 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.
