Linear Alkyl Benzene Sulphonic Acid
Linear Alkyl Benzene Sulphonic Acid (LABSA 90%) is the main active ingredient in detergent powders, dishwash bars and cleaning liquids after neutralisation.
LABSA is made by sulphonating linear alkyl benzene with sulphur trioxide. On its own it is a viscous, dark, strongly acidic liquid; neutralised with caustic soda or soda ash it becomes sodium linear alkyl benzene sulphonate (LAS), the cleaning workhorse of the detergent industry.
LAS removes oily and particulate soil effectively, foams well, biodegrades and costs less than most alternatives. It is used in spray-dried and dry-mixed detergent powders, dishwash bars and pastes, and liquid detergents. Its calcium salt is an important emulsifier in agrochemical formulations.

Linear Alkyl Benzene Sulphonic Acid — frequently asked
LABSA is neutralised with caustic soda, soda ash or other alkalis to form sodium linear alkyl benzene sulphonate. The reaction is exothermic, so LABSA is added gradually to the alkali with stirring and temperature control.
Yes. LABSA ships as UN 2586 (alkylsulphonic acids, liquid), Class 8 corrosive, in UN-approved drums, IBCs or ISO tanks.
Yes. Linear alkyl benzene sulphonate made from LABSA is readily biodegradable under aerobic conditions, which is why it replaced the older branched alkyl benzene sulphonates.
Yes. Chemtrade manufactures and exports Linear Alkyl Benzene Sulphonic Acid (CAS 27176-87-0) from Surat, Gujarat, India to more than 55 countries, for customers in Personal Care & Home Care. Send your grade, quantity and destination port for a quotation within one business day.
