Nitrogen-based surfactants properties

These properties will be discussed as they apply to nitrogen-based surfactants. 

PLA/PCL-OMMT nano-composites were prepared effectively using fatty amides as clay modifier. The nano-composites shows increasing mechanical properties and thermal stability (Hoidy et al, 2010c). New biopolymer nano-composites were prepared by treatment of epoxidized soybean oil and palm oil, respectively plasticized PLA modified MMT with fatty nitrogen compounds. The XRD and TEM results confirmed the production of nanocomposites. The novelty of these studies is use of fatty nitrogen compoimds which reduces the dependence on petroleum-based surfactants (Al-Mulla et al., 2011 Al-Mulla et ah, 2011 Al- Mulla et ah, 2010c). 

These products show lipophilic properties (fatty amines) due to aUcyl chains. However, the hydrophilic characteristic of the nitrogen group is sufficient to allow them some water-based solubility. In practice, these products are amphiphilic and mainly used as surfactants. So they can be, quite easily, swept away from the skin by water or water-based washing solutions.
