Abstract
A low-foam emulsifier system is presented containing (a) an ethoxylate/propoxylate of one or more C -C fatty alcohols, where the ethoxylate/propoxylate contains 2 to 6 ethylene oxide units and 4 to 8 propylene oxide units, with (b) a fatty alcohol propoxylate or distillation residue of fatty alcohol or fatty alcohol propoxylate, where the fatty alcohol contains 12 to 24 carbon atoms and up to three propylene oxide units. The weight ratio of (a) to (b) is from 1:0.3 to 0.3:1. The emulsifier system produces a low amount of foam, and is useful in industrial metal processing applications such as cleaning, corrosion protection or cooling lubricant emulsions.
