Linear Alkyl Benzene (LAB)
Linear Alkyl Benzene (LAB) is the dominant industrial precursor for Linear Alkylbenzene Sulfonate (LAS), the most widely used biodegradable anionic surfactant in household detergents, industrial cleaners, and personal care formulations worldwide.
Product Description
Linear Alkyl Benzene (LAB)
High-Purity Surfactant Intermediate — Feedstock for LAS Detergent Production
CAS: 67774-74-7 EC: 267-051-0 LAB Content: ≥94%
Linear Alkyl Benzene (LAB) is the leading industrial precursor for Linear Alkylbenzene Sulfonate (LAS), the most widely used biodegradable anionic surfactant in household and industrial detergents. Royalchem Spain supplies industrial-grade LAB with a C10–C13 alkyl chain distribution compliant with GB/T 5177-2017, ready for direct SO₃ sulfonation, and delivered from our Valladolid distribution hub by Flexitank, ISO tank, or bulk chemical tanker.

Main Applications
Detergents & Household Cleaners
Primary feedstock for Linear Alkylbenzene Sulfonate (LAS) production via SO₃ sulfonation. LAS is the high-volume anionic surfactant in laundry powders, dishwashing liquids, and multi-purpose cleaners across the EU market.
Industrial & Institutional Cleaners
Used in heavy-duty degreasers, alkaline cleaners, and textile auxiliaries. Sulphonability ≥98.6% delivers consistent active matter yield and low colour after sulfonation for I&I formulators.
Agrochemical Adjuvants & Emulsifiers
Building block for non-ionic and anionic emulsifiers used as co-formulants in pesticide emulsifiable concentrates (EC), agricultural wetting agents, and oilfield surfactant systems.
Logistics & Packaging
Standard Packaging:
Flexitank (approx. 24 MT), ISO tank container (approx. 20 MT), or bulk chemical tanker. Drum packaging available on request.
Storage Conditions:
Store in tightly closed containers in a cool, dry, well-ventilated area away from heat, sparks, open flames, and incompatible materials. Not regulated under IMDG / IATA / ADR.
