Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group. Along with sodium laureth sulfate, they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products (soaps, shampoos, toothpaste etc.) and ...
Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15 , C 12 -C 13 and C 10 -C 13 , for detergent use. [ 1 ]
It is the raw material in the production of synthetic sulfonate detergents, which are found in a variety of household products such as soap, shampoo, toothpaste, laundry detergent, etc. Linear alkylbenzenes (LAB) and branched alkylbenzenes (BAB) are families of alkylbenzene used to prepare synthetic sulfonates. However, LABs are more ...
The resulting sulfonic acid is then neutralized with base to give sodium alkylbenzenesulfonate, which is subsequently blended with other components to produce cleaning products. [1] Dodecylbenzene (and its isomers) are precursors to linear alkylbenzene sulfonate detergents. [2]
Sodium benzenesulfonate is an organic compound with the formula C 6 H 5 SO 3 Na. It is white, water-soluble solid, It is produced by the neutralization benzenesulfonic acid with sodium hydroxide. It is also a common ingredient in some detergents. The compound typically crystallizes from water as the monohydrate. [1]
The most widely used surfactant linear alkylbenzene sulfonate (LAS) is an anionic surfactant. In builders, sodium triphosphate, zeolite A, sodium nitrilotriacetate (NTA) are the most important substances. Bleach-active compounds are usually sodium perborate and sodium percarbonate. Enzymes and fluorescent whitening agents are added into ...
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
Included are several fundamental benzene-based feedstocks such as ethylbenzene (precursor to styrene), cumene (precursor to phenol and acetone), linear alkylbenzene sulfonates (for detergents). [11] Sodium dodecylbenzene, obtained by alkylation of benzene with dodecene, is a precursor to linear alkylbenzene sulfonate detergents.
