Non-ionic Surfactant Ingredients or Chemicals
Description of Nonionic Surfactant: surfactants (Surface Active Ingredients) are chemicals used to lower the surface tension between different substances. They function in multiple ways, like dispersants, emulsifiers, detergents and foaming agents. Most Surfactants have the same structure, a long, hydrophobic tail and a hydrophilic head. The tails are almost identical in most surfactants, they mainly differ in the hydrophilic head. This head can either be non-ionic, anionic, cationic or amphoteric. Whatever the structure, most surfactants work by creating micelles. These are small bubbles in which the surfactants have arranged themselves with their hydrophilic heads towards the solution, and the hydrophobic tail towards the center. This traps particles inside and allows it to function like a cleaning agent.
Non-ionic surfactants have a neutral hydrophilic head. This makes them better for oily emulsions than Anionic Surfactants. For this reason, the two are often combined for use in multi-purpose cleaning applications. Compared to Anionic Surfactants, Non-ionic surfactants are relatively low-foaming. Exclusive to Non-ionic Surfactants is the so-called cloud point, this is the temperature at which the solution starts to become cloudy. Most Nonionic Surfactants work best at or near this temperature, therefore this is certainly something to pay attention to. Common Non-ionic Surfactants are Ethoxylates, Amine Oxides (for example IngreNox M30), Cocoates (IngrePol PEG-7GC) and Alkyl Polyglucosides (eg Lauryl Glucoside50).
