This document primarily applies to surfactants obtained by reaction of ethylene oxide with hydrophobic base molecules, such as fatty alcohols, fatty acids, long-chain alkylphenols, fatty amines, fatty acid esters of sugar derivatives among other ethoxylated non-ionic surfactants, which are by far the most commonly used. NOTE Other non-ionic surfactants containing other structural units, such as propylene oxide-ethylene oxide block copolymers, have distinctive behaviours that make the determination of the cloud point more difficult. This leads sometimes to a gradual turbidity over a temperature range of several degrees or even to the occurrence of two cloud points at significantly different temperatures.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Surface active agents.
