Dodecyl benzene sulfonic acid sodium is neutral, are sensitive to water hardness, not easy oxidation, foaming power is strong, high detergency, easy, with a variety of additives to lower cost, mature synthesis process, application field widely, is a very good anionic surfactant.
As a kind of anionic surfactant, sodium dodecyl benzene sulfonate has good surface activity and strong hydrophilicity, which can effectively reduce the tension of oil-water interface and achieve emulsifying effect. Therefore, sodium dodecyl benzene sulfonate has been widely used in cosmetics, food, printing and dyeing auxiliaries, pesticide and other emulsion preparation.
Dodecyl benzene sulfonic acid sodium is a kind of anionic surfactant, can make the fabric, plastic and other surface water affinity, ionic surfactants and conductive function at the same time, thus it can be make the electrostatic leakage in time, thereby reducing risk and inconvenience caused by static electricity.
In the aspect of textile auxiliaries, it is often used as cotton fabric refining agent, desizing agent, dyeing levelling agent, and metal degreasing agent in the process of metal plating. Used in the paper industry as resin dispersant, felt detergent, deinking agent; Used in leather industry as osmotic degreasing agent; Used as anti-caking agent in fertilizer industry; In the cement industry, it is used in many aspects, such as aerating agent, or alone or as a combination.
