1. Washing effect
Alkyl benzenesulfonic acid sodium is yellow oil, after purification can form hexagonal or oblique square strong flake crystal, has a slight toxicity, has been international
Safety organization identified as safe chemical raw materials. Sodium alkyl benzenesulfonate can be used in fruit and tableware cleaning, in the amount used in washing
Large, because of the use of large-scale automated production, low price, in the detergent used in alkyl benzene sulfonate sodium branched chain structure (ABS)
And straight chain structure (LAS). The branched chain structure has low biodegradability and will cause pollution to the environment, while the straight chain structure is easy to biodegrade biological health
The solution can be more than 90%, and the degree of environmental pollution is small.
Sodium dodecyl benzene sulfonate is neutral, more sensitive to water hardness, not easy to oxidation, foaming power is strong, high detergents, easy to complex with various additives
It is an excellent anionic surfactant with low cost, mature synthetic technology and wide application field. Dodecyl benzene sulfonic acid
Sodium has significant decontamination effect on granular dirt, protein dirt and oil dirt, especially on natural fiber granular dirt washing effect.
The detergency increased with the increase of washing temperature, and the effect on protein fouling was higher than that of non-ionic surfactants, and the foam was rich. But.
Alkyl benzene sulfonate sodium has two shortcomings, one is poor resistance to hard water, decontamination performance can be reduced with the hardness of water, so its main activity
The detergent of the agent must be mixed with appropriate chelating agent. Second, the defatting force is strong, and there is a certain irritation to the skin when washing the clothes by hand
It should be rinsed with cationic surfactant as softener. In recent years, in order to obtain better comprehensive washing effect, dodecyl benzene
Sodium sulfonate is often combined with non-ionic surfactants such as fatty alcohol polyoxyethylene ether (AEO). Sodium dodecyl benzene sulfonate is the main use
Is the preparation of various types of liquid, powder, granular detergent, cleaning agents and cleaners.
