Soap is a surfactant, or a compound that lowers the surface tension of a liquid soap, in particular, decreases the surface tension of water by weakening the hydrogen bonds that make water such a special substance. Hlb system (hydrophilic - lipophilic balance) is used to determine the quantity and type of surfactant that is needed to prepare a stable emulsion.
