SDBS, short for Sodium dodecyl benzene sulfonate, white or light yellow powder or flake solid. It is difficult to volatilize, but it easy to dissolve in water and become a subtransparent solution. For alkali, dilute acid, it has stable hard water properties. SDBS is microtoxicity. It is commonly used as an anionic surfactant.
According to the physicochemical property,
Sodium Dodecylbenzene Sulfonate has three main functions.
Sodium alkyl benzene sulfonate is a yellow oil, which can form hexagonal or rhombic strong flake-like crystal. It has microtoxicity and has been recognized by the international security organization as a safe chemical raw material. Sodium alkyl benzene sulfonate can be used to clean fruit and tableware. Sodium alkyl benzene sulfonate used in detergent has branched chain structure (ABS) and linear structure (LAS). The branched chain structure has small biodegradability. It can cause environmental pollution. The linear structure is easier biodegradation more than 90%. It brings little influence to environment.
Sodium dodecylbenzene sulfonate has a significant effect on the granular fouling, protein fouling, and oil fouling. It is better to clean granular fouling on natural fibers. The detergency of SDBS is enhanced with the increase of temperature. The effect on protein fouling is better than that of the non-ionic surfactant. However, there are two disadvantages of sodium dodecyl benzene sulfonates, one is poor hard water tolerance and the detergency can be reduced with the hardness of the water. Therefore, Therefore, the detergent must be used with the appropriate chelating mixture. Second, the decreasing ability is too strong. It is irritant to the skin when washing by hand. The washed clothes feel bad. In recent years, sodium dodecyl benzene sulfonate is often used with nonionic surfactants such as fatty alcohol polyoxyethylene ether (AEO) for better washing effect. The main purpose of sodium dodecyl benzene sulfonate is to make a variety detergents.
The emulsifier is a kind of substance that improves the surface tension between various components in the emulsion and forms stable dispersion system or emulsion. There are hydrophilic groups and lipophilic groups in its molecule. And they gathered on the oil/water boundary. They also can reduce the interfacial tension and reduce the energy required to form the emulsion, so as to improve the energy of the emulsion.
As a kind of anionic surfactant, sodium dodecyl benzene sulfonate has good surface activity and strong hydrophilicity. And it effectively reduces the tension of oil and water surface to emulsification. Therefore, sodium dodecyl benzene sulfonate has been widely used in the preparation of cosmetics, food, printing and dyeing auxiliaries and pesticides.
All objects have the electrostatic charges. The charges can be negative charges or positive charges. The accumulation of static charges affects our life or industrial production. The chemical used to direct and eliminate harmful electric charges is called antistatic agent. Sodium dodecyl benzene sulfonate has an electrically conductive function. Therefore, static electricity can be eliminated in time to reduce the danger and inconvenience caused by static electricity.
Sodium dodecyl benzene sulfonate products are widely used. In addition to the above several functions, SDBS also can be used as cotton fabric refining agent and desizing agent in textile. Used as resin dispersant, felt detergent and deinking agent in the papermaking industry. Used as an osmotic degreaser in the leather industry. Used as an anti-blocking agent in the fertilizer industry. Used in the cement industry as a gassing agent, or used separately or in conjunction with components.
The SDBS products of IRO Coating Additive Co,.Ltd have passed the ISO9001 quality certification and have been recognized by many clients. IRO sodium dodecyl benzene sulfonate products also have a competitive price.
