The washing effect
Sodium Dodecyl benzene Sulfonate-SDBS (CAS:25155-30-0) is a yellow oily body that can form hexagonal or inclined square strong sheet crystals with mild toxicity. It has been identified as a safe chemical raw material by international safety organizations. Sodium alkyl benzenesulfonate can be used in fruit and tableware cleaning, the largest amount used in washing penalty, due to the use of large-scale automated production, low price, sodium alkyl benzenesulfonate used in detergent has branched chain structure (ABS) and straight chain structure (LAS) two, branched chain structure biodegradability is small, will cause pollution to the environment, However, the straight chain structure is easy to biodegrade and the biodegradability can be more than 90%, and the environmental pollution degree is small.
Sodium Dodecyl benzene sulfonate-SDBS (CAS:25155-30-0) is neutral and sensitive to water hardness, is not easy to be oxidized, has strong foaming power and high detergent power, and is easy to be compounded with various additives with low cost, mature synthesis process and wide application field. It's a very good anionic surfactant. Dodecyl benzenesulfonate has significant decontamination effect on granular dirt, protein dirt and oily dirt, especially on the natural fiber granular dirt washing effect, the decontamination effect increases with the washing temperature, protein dirt is higher than non-ionic surfactants, and rich foam. But there are two shortcomings of sodium dodecyl benzene sulfonate, one is poor hard water resistance, decontamination performance can be reduced with the hardness of water, so its main active agent detergent must be matched with the right amount of ao mixture. Second, the defatting force is stronger, hand washing has a certain irritation to the skin, the clothes feel worse after washing, it is appropriate to use cationic surfactant as softener rinsing. In recent years, in order to obtain a better comprehensive washing effect, sodium dodecyl benzene sulfonate is often combined with non-ionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). Sodium dodecyl benzene sulfonate-SDBS is mainly used to prepare various types of liquid, powder and granular detergents, cleaning agents and detergents.
