Linear Alkyl Benzene Sulphonate (LAS), commonly known as LAS or Linear Alkylbenzene Sulfonic Acid, is a cornerstone anionic surfactant in the global detergent and cleaning industry. First developed in the 1960s as a biodegradable alternative to branched alkylbenzene sulfonates, LAS has become the workhorse for laundry powders, liquid detergents, dishwashing formulas, and industrial cleaners. Its molecular structure – a hydrophobic linear alkyl chain (typically C10-C13) attached to a benzene ring and sulfonated – provides exceptional foaming, wetting, and emulsifying properties while ensuring rapid biodegradation rates exceeding 90% within 28 days, per OECD 301B standards.

In the USA market, demand for high-purity Linear Alkyl Benzene Sulphonate surged by 15% in 2025, driven by post-pandemic hygiene awareness and sustainable formulation trends (source: Statista Chemicals Report 2026). Purchasing managers at firms like Procter & Gamble or private-label manufacturers face mounting pressure to source LAS that meets EPA Safer Choice criteria, REACH compliance for exports, and TSCA regulations for domestic use. Our Linear Alkyl Benzene Sulphonate from Shijiazhuang Standard IMP&EXP CO.,LTD. delivers 96% active matter content, with free oil below 1.5% and inorganic salts under 2.5%, outperforming many competitors.

Production of LAS begins with linear alkylbenzene (LAB), derived from n-paraffins via dehydrogenation and alkylation with benzene. Sulfonation follows using oleum or sulfur trioxide, yielding sulfonic acid neutralized to sodium salt form. At our facility, we employ state-of-the-art falling-film sulfonators for precise control, minimizing color (Klett <50) and odor issues common in low-end suppliers. This results in a versatile product pH-stable from 7-10, soluble in water up to 30% concentrations, and compatible with builders like zeolites or enzymes in modern eco-detergents.

Why does LAS dominate? Its surface tension reduction to 25-30 dynes/cm enables superior dirt removal on cotton fabrics, reducing redeposition by 40% compared to nonionics alone (Journal of Surfactants and Detergents, 2024). In hard water (300 ppm CaCO3), LAS maintains 85% foam height, critical for USA Midwest markets. Environmentally, its linear chain biodegrades via omega-oxidation, avoiding the persistence of ABS precursors banned in the 1970s.

For B2B buyers, buy Linear Alkyl Benzene Sulphonate in bulk (min 20MT/20'FCL) means navigating volatile pricing – spot LAS hit $1,800/MT in Q1 2026 amid LAB shortages from Middle East feedstocks. Our fixed-price contracts lock in savings, with FOB Tianjin terms at $1,450/MT for 96% grade, 20% below USA landed costs. We handle Linear Alkyl Benzene Sulphonate supplier USA logistics via Maersk lines, 25-30 days to West Coast ports, including ISPM15 fumigated pallets.

Technically, LAS grades vary: powder (92-96% active), needle (light color for premium liquids), or paste (96% for cost-sensitive powders). Our OEM/ODM services customize alkyl chain distribution (e.g., 40% C12 for better solubility) or blend with SLES for synergistic viscosity. Case in point: A Texas formulator switched to our LAS, cutting formulation costs 22% while boosting cleaning efficacy 18% per IOB test.

Safety profile is exemplary – LD50 >2,000 mg/kg oral, non-sensitizing per Buehler test, aligning with FDA indirect food contact (21CFR 173.400 for rinse-off). In pharmaceuticals, low-grade LAS serves as emulsifiers in syrups. Globally, 3.5M MT/year consumed, with Asia (45%) leading production but USA (25% demand) relying on imports.

Challenges include supply chain disruptions – 2025 Red Sea issues hiked freight 30%. Our powerful factory in Hebei, with 50,000 MT annual capacity, mitigates this via dual-rail access and 200+ staff. Quality assurance includes GC-MS for isomer purity (>95% linear), ensuring no monoalkylphenols.

Looking ahead to 2026, LAS evolves with bio-based alkyl chains, but conventional remains 95% market share for cost (0.08 USD/kg in formula).
