Product Usage
Emulsion dispersant
An emulsifier is a substance that improves the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifiers are surface active substances with both hydrophilic and oleophilic groups in the molecules, which gather at the oil/water interface, can reduce the interfacial tension and reduce the energy required to form the emulsion, thereby increasing the energy of the emulsion. As an 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 emulsification. Therefore, sodium dodecyl benzene sulfonate has been widely used in the preparation of emulsions such as cosmetics, food, printing and dyeing auxiliaries and pesticides.
Antistatic agent
Any object has its own electrostatic charge, this charge can be negative or positive charge, the accumulation of electrostatic charge makes life or industrial production affected or even harmful, will gather harmful charge guide, eliminate so that it does not cause inconvenience or harm to production, life chemicals called antistatic agents. Sodium dodecyl benzene sulfonate is an anionic surfactant, which can make fabrics, plastics and other surfaces close to water, while the ionic surfactant has a conductive effect, which can make electrostatic leakage in time, thereby reducing the danger and inconvenience caused by static electricity.
Other role
The use of sodium dodecyl benzene sulfonate products is very wide, in addition to the above several aspects of the application, in the textile additives are often used as cotton fabric refining agent, desizing agent, dyeing leveling agent, in the metal plating process used as metal degreasing agent; Used in paper industry as resin dispersant, felt detergent, deinking agent; Used as penetrant degreaser in leather industry; Used as anti-caking agent in fertilizer industry; In the cement industry, it is used as an aerating agent in many aspects, either alone or as a combination ingredient.
Detergency
It is recognized as a safe chemical raw material by the international safety organization. Sodium alkyl benzene sulfonate can be used in fruit and tableware cleaning, the largest amount used in detergent, due to the use of large-scale automated production, the price is more advantageous than the same type of surface activity, sodium alkyl benzene sulfonate used in detergent has a branched chain structure, branched chain structure is small biodegradability, will cause pollution to the environment, and the straight chain structure is easy to biodegrade, The biodegradability can be greater than 90%, and the degree of environmental pollution is small. Sodium dodecyl benzene sulfonate has significant decontamination effect on particle dirt, protein dirt and oily dirt, especially on natural fiber particle dirt, decontamination power increases with the washing temperature, the effect on protein dirt is higher than that of non-ionic surfactants, and foam is abundant. However, sodium dodecyl benzene sulfonate has two disadvantages, one is poor resistance to hard water, decontamination performance can be reduced with the hardness of water, so the detergent with its main active agent must be used with an appropriate amount of chelating agent. Second, the degreasing force is strong, hand washing has a certain irritation to the skin, the feel of the clothes is poor after washing, it is appropriate to use cationic surfactants as softening agents. In recent years, in order to obtain better comprehensive washing effect, sodium dodecyl benzene sulfonate is often used in combination with non-ionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). The main use of sodium dodecyl benzene sulfonate is to prepare various types of liquid, powder, granular detergents, cleaning agents and cleaning agents.
