What is alkyl benzene sulfonate used for?

Alkyl benzene sulfonate (ABS) refers to a family of branched chain organic chemical compounds that were used as detergents. They are regarded as “hard” detergents due to their resistance to biological degradation.

Is alkyl benzene sulfonate harmful?

Linear alkylbenzene sulfonate (LAS) is a common organic pollutant in freshwater environments. Studies have shown that the toxicity of LAS to aquatic plants is directly related to the LAS concentration and depends on the plant species.

Is Las and Labsa same?

Linear alkylbenzene sulfonate (LAS), the world’s largest-volume synthetic surfactant, which includes the various salts of sulfonated alkylbenzenes, is widely used in household detergents as well as in numerous industrial applications. The LABSA market is driven by the markets for LAS, primarily household detergents.

What is LAS in detergent?

Linear alkylbenzene sulphonate (LAS) is an anionic surfactant. LAS is one of the major anionic surfactants used on the market. Important application products are household detergents, such as laundry powders, laundry liquids, dishwashing products and all-purpose cleaners.

Is benzene used in detergent?

Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers. Benzene is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.

What is LABSA in dishwashing liquid?

Sulfonic acid, LABSA is a batch of organic sulfur compounds that are used in most dishwashing detergents, detergent powder, cleaning powder, washing powders, detergent cake, liquid soap, soaps etc. It is used as a foaming agent and cleaning agent in most formulations.

Are sulfates and sulfonates the same?

Sulfates are made by the reaction of fatty alcohol or fatty alcohol ethoxylates with reagents like SO3 or chlorosulfonic acid (CSA). Sulfonates are compounds that possess a carbon sulfur bond. They include things like alpha olefin sulfonate (AOS). Alpha olefin sulfonates are made by reaction of alpha olefin and SO3.

Is Labsa toxic?

The product is a corrosive substance. Contact with the eyes may cause ocular lesions and contact with the skin may cause burns. It is seriously irritating to the mucous if swallowed. The product is harmful if ingested.

What is the pH of LABSA?

LABSA is quite absorbent and its biodegradability is above 90% . Linear Alkylbenzene Sulphonic Acid is extensively applied anionic surfactant….[Specifications ]:

What is detergent alkylate?

Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group. They were first introduced in the 1930s in the form of branched alkylbenzene sulfonates (BAS).

How are alkylbenzene sulfonates different from other surfactants?

Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group.

When did alkylbenzene sulfonates start to be used?

They were first introduced in the 1930s in the form of branched alkylbenzene sulfonates (BAS) however following environmental concerns these were replaced with linear alkylbenzene sulfonates (LAS) during the 1960s.

What kind of surfactant is alkylbenzene tail group?

Alkylbenzene sulfonates. Alkylbenzene sulfonates are a class of anionic surfactants, consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group. Along with SLES they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products ( soaps, shampoos,…

How is sulfonic acid neutralized in dodecylbenzene?

The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid. The sulfonic acid is subsequently neutralized with sodium hydroxide. The term “linear” refers to the starting alkenes rather than the final product.
