Abstract
Surface-active agents and their wide scope of applica¬tions is the subject of intensive research work by scientists all over the World. Their field of application due to the pfforts of those scientists is progressively extended. Besi-
their important role as detersive, wetting and emulsify¬ing agents, their usefulness In the textile industry has been recognized as dye leveling agents, fabric softening mate-and water repellent compounds* They have been succesu-used as germicides, fungicides, desinfectants and corro-inhibitors.
The aim of this work is the preparation of a novel of nitrogen containing surface-active agents derived fatty acids and amines with the view of studying their face activity and their applications. Two series of sur-itants were synthesized: a* cationio surfactants b. ampholytic surfactants-
present investigation deals with the following: The first series of the synthesized surface-active -agents the cationic surfactants resulting from the condensation lung chain fatty acids as stearic, palmitic and lauric acid ethylene diamine to give N-acyl-1,2-diaminoethane which with N-(2,3 epoxy propyl) triethyl ammonium chloride >ing the cationic surfactants, 2-hydroxy->-(2-heptadecyl, »cyl and undecyl amido-ethyl amino) propane-1-triethyl
