Summary:The use of a composition for defoaming non-aqueous foams, the prevention of foam formation, and/or the deaeration of various feeds, wherein said nonaqueous foam comprises a non-aqueous phase and a gas, and wherein said composition comprises at least: i) a non-ionic surfactant, wherein said non-ionic surfactant has a molecular structure as shown in (I), R1-CH(R2)-CH2-O-(A′O)m(A″O)n-H wherein R1 is an alkyl group having from 5 to 16 carbon atoms, R2 is an alkyl group having from 5 to 16 carbon atoms, A′O is an ethoxy (EO) or a propoxy (PO) group, A″O is an ethoxy (EO) or a propoxy (PO) group, m=0-10, n=20-150, and ii) a solvent.
