What is Linear Alkylbenzene (LAB)?

Linear Alkylbenzene (LAB) is a vital organic compound widely used in manufacturing biodegradable detergents and industrial cleaners. As a cost-effective surfactant precursor, LAB plays a pivotal role in producing Linear Alkylbenzene Sulfonate (LAS), the most common active ingredient in household and commercial cleaning products. With its high biodegradability and efficiency, LAB meets the growing demand for sustainable chemical solutions, making it indispensable for detergent manufacturers and procurement professionals.

The Evolution of LAB: A Sustainable Revolution

LAB transformed the detergent industry by solving environmental challenges posed by earlier alternatives:

  • 1930s–1940s: Branched Alkylbenzene Sulfonates (BAS) were common but caused toxic foam in waterways due to poor biodegradability.
  • 1950s: Research revealed BAS’s environmental harm, prompting demand for safer solutions.
  • 1964: LAB emerged as the eco-friendly alternative. Its linear molecular structure allowed rapid microbial breakdown, reducing water pollution.
  • Today: Over 90% of LAB production supplies global detergent markets, with advanced methods like the HF/n-paraffins process ensuring high purity and efficiency.

Chemical Properties and Molecular Structure

LAB is a colorless to pale-yellow liquid with the molecular formula C₁₂H₁₈. Its structure consists of a benzene ring attached to a linear alkyl chain, typically containing 10–14 carbon atoms. This linear configuration enhances solubility and sulfonation efficiency, critical for surfactant performance.

Key Properties:

  • Boiling Point: 280–320°C
  • Density: 0.85–0.87 g/cm³
  • Solubility: Insoluble in water, miscible with organic solvents
  • Biodegradability: >90% degradation within 28 days (OECD 301F test)

Types of Linear Alkylbenzene

LAB is available in various grades depending on customer application and regional standards. Specifications include:

  • Carbon Chain Distribution: C10–C13 or C10–C14

  • Bromine Index: ≤ 20

  • Sulfur Content: ≤ 1 ppm

  • Color (APHA): ≤ 10

  • Purity: ≥ 99.0%

Applications of Linear Alkylbenzene

1. Detergents & Cleaners

  • Household Detergents: LAB-derived LAS powers liquid/powder detergents, offering hard-water compatibility.
  • Industrial Cleaners: Used in degreasers and institutional products for large-scale operations.

2. Agriculture

  • Acts as an emulsifier in pesticides/herbicides for even crop coverage.

3. Textile Manufacturing

  • Removes oils and contaminants during fabric processing.

4. Oilfield Chemicals

  • Enhances oil recovery by reducing surface tension in reservoirs.

5. Paper Recycling

  • Aids in ink removal and improves paper texture.

6. Industrial Lubricants & Paints

  • Serves as an emulsifier in adhesives, coatings, and machinery lubricants.

How is Linear Alkylbenzene Produced?

LAB production involves five key steps:

  1. Alkylation: Reacting benzene with linear paraffins (using HF or AlCl₃ catalysts).
  2. Separation: Isolating LAB from byproducts.
  3. Purification: Removing impurities via clay treatment or distillation.
  4. Drying: Eliminating moisture through vacuum drying.
  5. Quality Control: Testing for purity, chain length, and compliance.

Safety & Handling Guidelines

While LAB poses low acute toxicity, proper protocols are essential:

  • PPE: Gloves, goggles, and ventilated masks.
  • Spill Management: Contain with inert absorbents; avoid water runoff.
  • Disposal: Follow local regulations for hydrocarbon waste.

Regulatory bodies like OSHA and ECHA classify LAB as non-hazardous under normal use.

Linear Alkylbenzene Packing

LAB is typically shipped in:

  • ISO Tanks (20–25 tons)
  • Steel Drums (200 kg)
  • Flexitanks (24,000 liters)

Storage Tips:

  • Keep containers sealed in cool, dry areas (<30°C).
  • Avoid contact with oxidizing agents.
  • Shelf life: 12 months from production

Why Choose LAB?

Linear Alkylbenzene combines performance, sustainability, and cost-efficiency, making it ideal for detergent manufacturers and industrial buyers. With stricter environmental norms, transitioning to LAB-based products ensures compliance and market competitiveness.
