(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".
A substance that helps an emulsion form, or helps keep an emulsion from separating.
‘The lecithin in egg yolks is often used as an emulsifier.’;
(biochemistry) A lipoprotein in the tissues of the lung that reduces surface tension and permits more efficient gas transport.
a surface-active agent that promotes the formation of an emulsion
a substance capable of reducing the surface tension of a liquid in which it is dissolved
a substance which tends to reduce the surface tension of a liquid in which it is dissolved.
Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, or dispersants.
