**6. Conclusions**

Gemini imidazolines are the surfactants that have been continuously getting explored for their varied application. At the one end where, the pendant structure of imidazoline surfactants make them easily absorbable on to the polar surface on the same tome the fatty alkyl chain imparts hydrophobicity thus defending so many polar surfaces by the adverse environmental impact and increase the life of surfaces. Presence of two surfactants molecules with in the molecule, drastically minimize their CMC values thus making the surfactants cost effective. Heterocyclic atom present in the ring of hydrophilic group imparts antimicrobial properties in the molecule thus making the surfactants suitable as antimicrobial agents. Furthermore, their existence in various forms like cationic, amphoteric, nonionic increase their applicability in various more industrial sectors.
