Product Description:

Linear alkylbenzene sulfonates （LAS）, SDBS for short, white powder. It is difficult to volatilize, easily soluble in water and soluble in water to form a translucent solution. It is stable and slightly toxic to alkali, dilute acid and hard water. It is a commonly used anionic surfactant.

Application fields:

1. Washing effect: Linear Alkylbenzene Sulfonates（LAS） is a yellow oil. After purification, it can form hexagonal or oblique square strong flake crystals. It has slight toxicity and has been recognized as a safe chemical raw material by the safety organization. Linear Alkylbenzene Sulfonates（LAS） can be used in fruit and tableware cleaning. It is widely used in detergents. Due to the large-scale automatic production and low price, Linear Alkylbenzene Sulfonates（LAS） Used in detergents has two kinds of branched chain structure (ABS) and linear chain structure (LAS). The branched chain structure has little biodegradability and will pollute the environment, while the linear structure is easy to biodegradate, the biodegradability can be greater than 90%, and the degree of environmental pollution is small. Linear  alkylbenzene  sulfonates （LAS） is neutral, sensitive to water hardness, not easy to oxidize, strong foaming power, high decontamination power, easy to mix with various additives, low cost, mature synthesis process and wide application fields. It is a very excellent anionic surfactant.

2. Emulsifier dispersant: emulsifier is a substance that improves the surface tension between various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic groups in the molecule. It gathers on the oil / water interface, which can reduce the interfacial tension and reduce the energy required to form the emulsion, so as to improve the energy of the emulsion. As an anionic surfactant, linear alkylbenzene sulfonates  （LAS） has good surface activity and strong hydrophilicity, which can effectively reduce the tension of oil-water interface and achieve emulsification. Therefore, linear  alkylbenzene  sulfonates （LAS） has been widely used in the preparation of emulsions such as cosmetics, food, printing and dyeing auxiliaries and pesticides.

3. Antistatic agent: any object has its own static charge, which can be negative or positive. The accumulation of static charge affects or even endangers life or industrial production. Chemicals that guide and eliminate the accumulated harmful charge so that it will not cause inconvenience or harm to production and life are called antistatic agents. Linear alkylbenzene  sulfonates（LAS） is an anionic surfactant, which can make the surface of fabrics and plastics hydrophilic to water. At the same time, the ionic surfactant also has the function of conductivity, so it can make the static electricity leak in time, so as to reduce the danger and inconvenience caused by static electricity.

4. Other functions: linear alkylbenzene  sulfonates （LAS） is widely used. In addition to the above applications, it is often used as cotton fabric refining agent, desizing agent, leveling agent during dyeing, and metal degreasing agent in the process of metal electroplating; Used as resin dispersant, felt detergent and deinking agent in paper industry; Used as penetrating degreasing agent in leather industry; Used as anti caking agent in fertilizer industry; In the cement industry, it is used as aerator and other aspects, either alone or as a matching component.
