Surfactant Definition and Examples - Science Notes and Projects
网页2022年1月1日 · A surfactant is a compound that reduces surface tension between two phases, such as two liquids, a liquid and gas, or even a liquid and solid. For example, adding detergent reduces surface tension in oily water, making it easier to remove soiling from fabrics or cookware.

Surfactant - Wikipedia
网页Surfactants are among the most widespread and commercially important chemicals. Private households as well as many industries use them in large quantities as detergents and cleaning agents, but also for example as emulsifiers, wetting agents, foaming agents, antistatic additives, or dispersants.

网页2024年2月15日 · Surfactant reduces surface and interfacial tension by adsorbing to surfaces and interfaces. “interface” refers to the link between two immiscible phases, while “surface” refers to a gas, such as air.
Surfactant - an overview | ScienceDirect Topics
网页Surfactants are substances that create self-assembled molecular clusters called micelles in a solution (water or oil phase) and adsorb to the interface between a solution and a different phase (gases/solids).
What Are Surfactants | School of Chemistry - University of Bristol
网页A surfactant molecule posses both a polar “water-loving” headgroup attached to a non-polar “water-hating” (or “oil-loving”) tail. Due to their dual nature, they are associated with many useful interfacial phenomena, and as such are key components for many diverse industrial products and processes.

网页Surfactant classes that are generally known to be mild to the skin include polyol surfactants (alkyl polyglucosides), zwitterionic surfactants (betaines, amidobetaines, and isethionates), and many polymeric surfactants.
Types of Surfactants, their Synthesis, and Applications
网页2014年9月26日 · Share. Summary. Surfactant is a widely used contraction for surface active agent, which literally means active at a surface. It is usually associated with relatively low molecular weight substances. The surfactant may be viewed as a molecule consisting of a lyophilic and a lyophobic part.
