Dry Goods – What Is Sodium Alkylbenzene Sulfonate Used In Laundry Detergents?

by:Jingliang     2023-07-21
The difference in the size and structure of the alkyl group is directly related to the performance. For example, the linear sodium alkylbenzene sulfonate in washing powder technology products has a detergency that increases with the chain length, and decontamination starts from 9 carbon atoms. Power, detergency when the number of carbon atoms reaches about 18. In addition... The size and structure of the alkyl group are directly related to the function. For example, the linear sodium alkylbenzene sulfonate in washing powder technology products, its detergency increases with the chain length, starting from carbon atoms When the number of carbon atoms is 9, it starts to exert detergency, and when the number of carbon atoms reaches about 18, it has detergency. In addition, the number of carbon atoms of branched alkylbenzene is 12=14, which can exert excellent detergency, but compared with the straight chain type with the same number of carbon atoms, its detergency is poor. In terms of product foaming, in terms of the foaming power of the straight-chain type, the number of carbon atoms in the straight-chain type is 12-14. In terms of foam firmness, the number of carbon atoms is 14, and the foaming power of the branched chain type with 12-14 carbon atoms is also better, which is slightly worse than that of the straight chain type. In terms of wetting force, the number of carbon atoms is generally the same. The wetting power of the branched chain type is also good. In terms of nominal tension, a straight-chain type having 14 carbon atoms is preferable, and a branched-chain type having 12 carbon atoms is preferable. After being made into powdered laundry detergent formula products, the straight chain type is very strong in terms of avoiding moisture absorption and agglomeration. In terms of solubility, the solubility of the straight-chain type decreases with the increase of the carbon chain, the solubility of the branched-chain type is better than that of the straight-chain type, and the washing performance of the straight-chain type with 12-14 carbon atoms is good. Therefore, this product is essential in the detergent formula. The properties of sodium alkylbenzene sulfonate in detergent technology products vary depending on the position of the alkyl group and the sulfonic acid group on the benzene ring, as well as the size and structure of the alkyl group.
