WebThe hydrophilic portion of an emulsifier could originate from a variety of groups, for example the ionized forms of SO 4 Na, COONa, and COOK. The lipophilic groups are … In the bulk aqueous phase, surfactants form aggregates, such as micelles, where the hydrophobic tails form the core of the aggregate and the hydrophilic heads are in contact with the surrounding liquid. Other types of aggregates can also be formed, such as spherical or cylindrical micelles or lipid bilayers. Meer weergeven Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. Surfactants may function as emulsifiers, wetting agents, detergents Meer weergeven The human body produces diverse surfactants.
