Abstract
Nonionic surface-active agents prepared by the addition of ethylene oxide to mixtures of alcohols containing from 8 to 20 carbon atoms are often solids or mixtures of solids and liquids at room temperatures. The pour points of such nonionic surfactants can be lowered without appreciably adversely affecting other properties by the sequential addition of ethylene oxide, propylene oxide and ethylene oxide to the alcohol if the initial oxyethylene block contains from 30% to 60% of the total oxyethylene groups in the molecule.
