The aim of this research is to show that the insaturated fatty acids and their
esters acquire quite interesting surfactant properties when they are sulfonated
with SO٣ or HSO٣Cl.
They are of great interest by virtue of being derived from renewable
natural
source in addition to their surface tension lowering, foaming power, rapid
biodegradability and excellent performance in hard water. Yet, they achieve an
improvement in soap behaviour in hard water. Therefore this type of
surfactant can form a particularly effective synergistic system.
