Anionic Surfactants for Cleaning Anionic Surfactants for Cleaning

Anionic surfactants are the earliest and most widely used functional chemical products in the field of cleaning. At the same time, it is also one type of most production, most varieties and the most maturely industrialized. Compared with nonionic surfactants provided by the nonionic surfactant suppliers, anionic surfactants have the advantages of being resistant to acids, alkalis, hard water and good low temperature fluidity, etc. Although their cleaning effect is slightly lower than that of nonionic surfactants, they also have a certain price advantage. For these reasons, anionic surfactants is one kind of the most diverse and productive surfactants in the surfactants family. Anionic surfactants can be divided into sulfonate, carboxylate, sulphate and phosphate salts etc.


Of all the anionic surfactants produced by the surfactant manufacturers, sodium dodecylbenzenesulfonate and its sodium salt and sodium aliphatic ether sulphate are the two oldest and most mature anionic surfactants with simple production processes. Sodium sulfonate of ethoxylated fatty acid methyl esters has been able to increase its market share due to its strong detergent power, but its raw material--long-chain fatty acid methyl esters is not stable enough and breaks down easily, which limits its development to some extent.Sodium secondary alkyl sulfonate, with its excellent permeability and excellent wetting properties, has always been an indispensable main ingredient for a wide range of wetting agents.


Therefore, anionic surfactants are an indispensable part of surfactant compounding products. The addition of a certain amount of anionic surfactant to a surfactant system can, according to its properties, significantly improve the system's performance in terms of detergent removal, salt resistance, acid and alkali resistance, anti-static, etc., greatly reducing the production cost and thus enhancing the competitiveness of the product.
