Compared to traditional soaps BAS offered superior tolerance to hard water and better foaming. ácido dodecilbenceno sulfónico (Spanish); Acide dodécylbenzènesulfonique (French).

[6] BAS was widely blamed for the formation of large expanses of stable foam in areas of wastewater discharge such as lakes, rivers and coastal areas (sea foams), as well as foaming problems encountered in sewage treatment[7] and contamination of drinking water.

The salt of the linear material has an LD50 of 2.3 mg/liter for fish, about four times more toxic than the branched compound; however the linear compound biodegrades far more quickly, making it the safer choice over time. Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group.

However following environmental concerns these were replaced with linear alkylbenzene sulfonates (LAS) during the 1960s. There's a problem loading this menu right now. Site Index   Please try again.

Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. In particular the Krafft point of the high 2-phenyl product (i.e. Please try again.
Biodegradability has been well studied,[6][18][19] and is affected by isomerization, in this case, branching. 150kg water and 150 kg NaOH) in the process of slurry making for the detergent industry. [9] The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid.

[2] In the most common route benzene is alkylated by long chain monoalkenes (e.g. LABSA is quite absorbent and its biodegradability is above 90% . the least branched isomer) remains below 0 °C up to 25% LAS whereas the low 2-phenyl cloud point is ∼15 °C.

[5] However, the highly branched tail made it difficult to biodegrade. Under ideal conditions the cleaning power of BAS and LAS is very similar, however LAS performs slightly better in normal use conditions, due to it being less affected by hard water.
