SYNTHESIS CHARACTERIZATION AND APPLICATIONS OF IMIDAZOLINIUM BASED CATIONIC SURFACTANTS

Surfactants are substances that reduce the surface tension of liquids and increase their ability to spread. Surfactants are substances found in cleaning products that aid in the removal of debris from the surface being cleaned. Gemini and monomeric surfactants were made by esterifying halogenated carboxylic acids with short chain fatty alcohols or acids with 2-chloroethanol, creating appropriate esters, and then treating them with spacers (1-methylimidazole). Surfactants based on imidazolium are particularly essential components in a variety of cosmetics. Proton NMR experiments were used to identify these surfactants. A number of factors are considered, including surfactant chemical structure, critical micelle concentration (CMC), melting point, and BOD analysis. The surfactant was synthesised using long chain fatty acid and haloalcohol at 60 C
