| surfactant |
Surfactants, also known as wetting agents, lower the surface tension of a liquid, allowing easier spreading, and the interfacial tension between two liquids. The term surfactant is a contraction of "Surface active agent". Surfactants are usually organic compounds that are amphipathic, meaning they contain both hydrophobic groups (their "tails") and hydrophilic groups (their "heads"). Therefore, they are typically sparingly soluble in both organic solvents and water. ...

| surface tension |
(Also called surface energy, surface free energy, capillary forces, interfacial tension.) The tangential force acting at the interface between a liquid and air (or, more correctly, its own vapor) caused by the difference in attraction between liquid molecules and gaseous molecules. Expressed either as a force per unit length of interface or as an energy per unit area of interface.

| surfactant |
A surface-active agent or wetting agent, such as Tween 20TM or Tween 80TM, TeepolTM, Lissapol FTM, AlconoxTM, etc. Surfactants act by lowering the surface tension and are common addenda to solutions used to surface sterilize materials prior to aseptic excision of explants. See detergent; wetting agent.
