Colloidal systems are of extremely widespread in nature and are of great practical importance in our daily life. Surfactants are very important in modern engineering and pharmaceutical soap and the complexes of soaps with different ligands are used in almost all sectors of national economy due to formation of micelles in solutions and high surface activity i.e. the ability of their molecules to form surface adsorption layers various edible oils like Mustard, Soyabean and Sesame play a vital role for its selection in various fields like pesticides, paints and herbicides etc. It is well known fact that benzothiazoles are derivatives of anilines and play a significant role in biological activities and have sufficient Industrial and analytical applications. Present work has been initiated with a view to obtaining a profile as to the nature and structure of complex of copper with long chain fatty acids in non-aqueous solvents that are of great significance in explaining their characteristics under different conditions.
