Sodium Dodecylbenzene Sulphonate 30%

Dodecyl benzene sulfonic acid sodium, the English name sodiumdodecylbenzenesulfonate, referred to as "SDBS, white or light yellow powder or flake solid. It is difficult to volatilize, readily soluble in water, and forms a semi-transparent solution when dissolved in water. It is chemically stable to alkali, dilute acid and hard water, and slightly toxic. It is a commonly used anionic surfactant. Sodium dodecylbenzene sulfonate, an anionic surfactant, is a very typical sulfonate with functions such as decontamination and emulsification. It can be used as a decontaminator and other applications, but its resistance to hard water is slightly weak. It works better when used in combination with chelating agents. It has a wide range of applications, and its typical use is in laundry detergent. Sodium alkylbenzene sulfonate is a yellow oily substance. After purification, it can form strong plate-like hexagonal or rhombic crystals. It is slightly toxic and has been recognized as a safe chemical raw material by international safety organizations. Sodium alkylbenzene sulfonate can be applied in the cleaning of fruits and tableware. The largest amount is used in detergents. Due to the large-scale automated production, it is low in price. There are two types of sodium alkylbenzene sulfonate used in detergents: branched-chain structure (ABS) and straight-chain structure (LAS). The branched-chain structure has low biodegradability and will cause environmental pollution, while the straight-chain structure is easy to biodegrade. The biodegradability of the chemical substances can be greater than 90%, and the degree of environmental pollution is small. Sodium dodecylbenzene sulfonate is neutral, sensitive to water hardness, not prone to oxidation, has strong foaming power, high decontamination power, is easy to be compounded with various additives, has a low cost, a mature synthesis process, and a wide range of applications. It is an outstanding anionic surfactant. Sodium dodecylbenzene sulfonate has a significant decontamination effect on particulate dirt, protein dirt and oily dirt. Its washing effect on particulate dirt on natural fibers is particularly good. The decontamination power increases with the rise of washing temperature. Its effect on protein dirt is higher than that of nonionic surfactants, and it produces rich foam. However, sodium dodecylbenzene sulfonate has two drawbacks. One is that it has poor resistance to hard water, and its decontamination performance can decrease with the hardness of water. Therefore, detergents with it as the main active agent must be used in combination with an appropriate amount of chelating agent. Second, it has a strong degreasing power. When washing by hand, it has a certain degree of irritation to the skin, and the clothes feel poor after washing. It is advisable to use cationic surfactants as softeners for rinsing. In recent years, in order to achieve better comprehensive washing effects, sodium dodecylbenzene sulfonate is often used in combination with nonionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). Sodium dodecylbenzene sulfonate is mainly used in the formulation of various types of liquid, powder and granular detergents, cleaning agents and cleaning agents, etc.
