ABSTRACT:
A defoaming composition of the following formula: ##STR1## wherein R is a hydrocarbon radical of from 10-20 carbon atoms and made be either saturated, unsaturated and either linear or branched in structure; R.sup.1 is a reactive alkoxy radical of from 2 to 4 carbon atoms; y is an interger of at least 1; A is an ethylene. propylene, or butylene group; and x is an integer of at least 1. The above composition can be used with oil-based defoaming aqueous system. The defoaming composition and process for defoaming are included.
