Schematic diagram o a micelle o ile in aqueous suspension, such as micht occur in an emulsion o ile in watter. In this example the surfactant molecules' ile-soluble tails project intae the ile, while the watter-soluble ends remain in contact wi the watter phase

Surfactants are compoonds that lawer the surface tension (or interfacial tension) atween twa liquids or atween a liquid an a solit. Surfactants mey act as detergents, wettin agents, emulsifiers, foamin agents, an dispersants.
