Biological surfactants are generally present in plants

Biological surfactants are generally present in plants, animals and microorganisms secretions? Excrement and rotting their product. 3 twin twin surfactant is a class of surfactants with two hydrophobic chains?  Food dehydrator  groups, and a bridging group of the special structure of the compounds, similar to the two conventional surfactants linked together by a bridge, bridging group which is a flexible group of common, a double oxide or a long chain alcohol and hydrocarbon type, such as the structure and the like. Anionic surface active agent is divided into twin? Three types of cationic and non-ionic, anionic oxygen bridged by double long-chain alcohol compound or a reaction connections,  machine for pellet  through the hydrocarbon. Twins surfactant is characterized not only has a high surface activity, but also has very low Krafft point and good solubility in water, it is difficult to compare with conventional surfactants, and therefore aroused great concern.
