Biosurfactants

Biosurfactants are biological cells and metabolic substances out of the sexes, with no synthetic surfactants are the structural features and Briquette machine, and because it is through the fermentation of low cost, easy degradation, environmental pollution, so it can form a potential flooding system has been quickly developed. Biosurfactant according to their hydrophilic groups which are divided into five categories: sugar-based hydrophilic lipid biosurfactant; with low shrinkage hydrophilic acyl amino acid-based reduction biosurfactant; to phosphoric acid group is a hydrophilic group based biosurfactant phospholipids; with carboxylic acid groups of the fatty acid-based biological hydrophilic surfactant; binding polysaccharide? protein and fat biosurfactant polymer. 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? Two ionic groups, and a bridging group of the special structure of the compounds, similar to the two conventional surfactants linked together by oil expeller, 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, cationic connected 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.
