Blend of surface-active + agent.
surfactant (plural surfactants)
- (chemistry) A surface-active agent, or wetting agent, capable of reducing the surface tension of a liquid; typically organic compounds having a hydrophilic “head” and a hydrophobic “tail”.
- Synonym: tenside
- (biochemistry) A lipoprotein in the tissues of the lung that reduces surface tension and permits more efficient gas transport.
