ABSTRACT The disclosure Synthesis & Application of a Novel Antimicrobial active provides a method of synthesis of organic complex starting from saturated fatty acid with a free base bioactive molecule containing nitrogen atoms. The reaction is usually conducted in refluxing alcohol. The product is synthesized by a acid-base reaction whereby the acid molecule is capable of donating a proton, to the free base molecule resulting in the formation of the desired complex. These complexes are very effective antimicrobial active against a variety of bacteria, fungi, protoZoa, helminthes and viruses. Individually, the antimicrobial actives of this invention are well known in the published literature, however the complexes of this invention are quite unique, novel and represent new antimicrobial compositions their isolation and characterization and precise usage in the formulations. The process is suitable for large-scale synthesis and involves simple and high-yielding techno feasible chemical transformations using low-cost commercially available raw materials. The complex has wide spread use in human personal care, industries and household applications , as the disclosed chemical has antimicrobial activity against gram positive, gram negative bacteria , yeast, mold, fungi.
