Linear Alkyl Benzene Sulphonic Acid

Linear Alkyl Benzene Sulphonic Acid (LABSA) is a synthetic organic compound derived from linear alkyl benzene sulfonation. It is a key anionic surfactant widely employed in industrial cleaning and detergent formulations. Supplied as a yellow to brownish viscous liquid, LABSA typically contains 90-96% active matter, concentrating its sulfonic acid groups that confer strong emulsifying and detergent capabilities. Procurement should note that LABSA is soluble in water and alcohols but insoluble in hydrocarbons. It exhibits an acidic pH range of approximately 1.5 to 3.5 in a 1% aqueous solution, requiring compatible handling materials. Avoid using LABSA with strong oxidizers or alkaline substances during storage and application to maintain stability and safety. The chemical formula is C18H30SO3H, reflecting its linear alkyl chain attached to the benzene sulfonic acid group. Typical dosage in detergent formulations ranges from 10-30%, depending on product requirements and desired cleaning power. It is supplied in bulk drums or intermediate bulk containers suitable for industrial scale usage.

In detergent manufacturing, LABSA acts as the primary surfactant delivering effective soil removal and foaming characteristics necessary for cleaning performance. Its sulfonic acid groups provide an anionic charge that reduces surface tension, allowing removal of oils and dirt from fabrics or surfaces. Without LABSA, detergent formulations lack the fundamental cleansing component essential for industrial laundry, household cleaning, and surface disinfecting products. Additionally, LABSA enhances process efficiencies in industries where emulsification and wetting are critical. It enables stable formulations and facilitates removal of impurities, thus improving final product quality across textile processing, water treatment, and metal cleaning. The chemical's activity and consistency directly impact manufacturing yields and operational reliability in these sectors.
