Abstract
Surfactant, as an abbreviation of “surface active agent”, is an organic compound that is amphiphilic comprising both hydrophilic groups(commonly referred to as “polar heads”) and hydrophobic groups(“nonpolar tails”). Based on the electron charges of the polar head parts, surfactants are classified as anionic, cationic, nonionic, zwitterionic. Many other pecular class of compounds also categorized in the types of gemini, cyclodextrin based, polymeric surfactants etc. Due to their some interesting properties such as nontoxicity, higher rate of biodegradability, high foaming capacity and optimal activity at extreme conditions like temperatures, pH and salinity, surfactants have been increasingly attracting the attention of the scientific and industrial community. Biocompatible, biodegradable, and/or nontoxic emulsion-based formulations of surfactants have great potential for applications in the food preparation and processing. Basics of surfactants and mainly there way of utility as food emulsifiers in food industries is thoroughly discussed.

ABSTRACT:
Nanocochleate is a novel lipid based drug delivery system offering systemic and oral delivery of various charged drug molecules. It is formed by negatively charged lipid bilayer. Nanocochleate can encapsulate drugs which are hydrophobic, positively charged, negatively charged and poor orally bioavailable. It is also very much beneficial for oral absorption for peptide drugs that possess a net positive charge. Nanocochleate is beneficial for molecules having binding sites inside the cell. The property that nanocochleates can facilitate cross membrane diffusion for charged and impermeable molecules finds wide application in drug delivery. Nanocochleate have been proven better than liposomes and more compatible with body environment. They differ from liposomes by its structure and compatibility to the body. Liposomes are lipid bilayer with aqueous inner environment and unlike liposomes nanocochleates are having charged lipid bilayer without aqueous environment and are multilayer lipid matrix i.e. Cochleate.

Various methods of its formulation, structure, merits demerits and wide range of application are described in this article.
