…Egg white, saponin, and gelatin are used as foaming agents, while soap and alkyl sulfates are used as surfactants. In order to form a strong adsorption molecular film along with surface activity, linear structures and somewhat hydrophilic agents are selected. In addition, foam stabilizers are generally used in combination to increase foam stability. Examples of foam stabilizers include amide acids, hydroxyammonium salts, ethylene oxide adducts of alkylamines, sulfoxides, maleic acid derivative condensates, and fatty acid polyhydric alcohol esters, with amides being particularly commonly used. … *Some of the terminology that refers to "foam stabilizer" is listed below.
