=== Non-ionic ===

Non-ionic surfactants have covalently bonded oxygen-containing hydrophilic groups, which are bonded to hydrophobic parent structures. The water-solubility of the oxygen groups is the result of [[hydrogen bonding]]. Hydrogen bonding decreases with increasing temperature, and the water solubility of non-ionic surfactants therefore decreases with increasing temperature.

Non-ionic surfactants are less sensitive to water hardness than anionic surfactants, and they foam less strongly. The differences between the individual types of non-ionic surfactants are slight, and the choice is primarily governed having regard to the costs of special properties (e.g., effectiveness and efficiency, toxicity, dermatological compatibility, [[biodegradation|biodegradability]]) or permission for use in food.<ref name="Ullmann" />

Fatty acid ethoxylates are a class of very versatile surfactants, which combine in a single molecule the characteristic of a weakly anionic, pH-responsive head group with the presence of stabilizing and temperature responsive ethyleneoxide units.<ref>{{Cite journal|last=Chiappisi|first=Leonardo|date=December 2017|title=Polyoxyethylene alkyl ether carboxylic acids: An overview of a neglected class of surfactants with multiresponsive properties|journal=Advances in Colloid and Interface Science|volume=250|pages=79–94|doi=10.1016/j.cis.2017.10.001|pmid=29056232}}</ref>
