Full Description

Sodium linear alkylbenzene sulfonate (LAS, CAS 68411-30-3) is a high-volume anionic surfactant, the sodium salt of linear alkylbenzene sulfonic acid. It is used as the primary detergent active in household and industrial laundry, dishwashing, and cleaning products. It also functions as an emulsifier, wetting agent, and processing aid in textiles and other industries.

Frequently Asked Questions

What is sodium linear alkylbenzene sulfonate (LAS)?

LAS (CAS 68411-30-3) is a high-volume anionic surfactant, the sodium salt of linear alkylbenzene sulfonic acid (LABSA). It is the primary detergent active in household and industrial laundry, dishwashing, and cleaning products. RawSource supplies it as a surfactant and detergent base.

What is sodium linear alkylbenzene sulfonate used for?

It is the primary anionic surfactant in laundry, dish, and cleaning products, and is used in industrial and institutional cleaners and degreasers, as an emulsifier and wetting agent, in textile processing, and as a wetting/emulsifying agent in agrochemical formulations. RawSource supplies it for detergent and industrial-cleaner manufacturing.

What is the difference between LAS and LABSA?

LABSA is the linear alkylbenzene sulfonic acid (the acidic precursor); LAS is its neutralized sodium salt. Formulators often buy LABSA and neutralize in-house, or buy the pre-neutralized LAS. Confirm which form fits your process and check the active content on the CoA.

What active concentration and packaging does RawSource supply for LAS?

LAS is typically supplied as an aqueous active solution or paste/slurry; active content varies by grade, so request a CoA. RawSource offers drums, totes, IBCs, and bulk supply. Contact us for available grades and a bulk quote.

What is the CAS number and HS code for LAS?

LAS is CAS 68411-30-3 with representative formula C16H25NaO3S. The HS classification is 3402.31. RawSource provides the SDS and CoA with each bulk shipment for formulation and import documentation.
