Linear Alkylbenzene Sulfonic Acid (LABSA)

Linear Alkylbenzene Sulfonic Acid (LABSA)

HS Code : 34023110

Linear Alkylbenzene Sulfonic Acid (LABSA) is a light yellow to brown viscous liquid widely recognized for its role in household and industrial detergent production. As an organic sulfur compound, LABSA contains both hydrophilic (water-attracting) and hydrophobic (oil-attracting) groups. This dual nature allows it to effectively bond with water while breaking down fats and grease, making it one of the most important raw materials in the cleaning industry.

Chemical Characteristics

• Chemical Formula: R–C₆H₄–SO₃H (R = C₁₀–C₂₀ hydrocarbon chain)
• Synonyms: Sulfonic Acid, Dodecylbenzene Sulfonic Acid, Lauryl Benzene Sulfonate
• Molecular Weight: ~326.5 g/mol
• Appearance: Light yellow to brown viscous liquid
• Melting Point: ~10 °C
• Boiling Point: ~315 °C
• Solubility: Highly soluble in water (~300 g in 100 g water at 25 °C)

Applications

• Detergent Industry (Primary Use)
  • Laundry powders and liquids
  • Dishwashing liquids
  • Household and surface cleaners
  • Industrial cleaning products (machinery, vehicles, equipment)
• Textile Industry
  • Used in dyeing, printing, and finishing
  • Improves fiber cleaning, dye absorption, and overall fabric quality
• Paints & Resins
  • Enhances dispersion of pigments and prevents sedimentation, ensuring a smooth finish
• Water Treatment
  • Functions as a coagulant, helping to remove oil, grease, and suspended solids
• Fabric Softeners
  • Provides softness and helps maintain fabric suppleness and brightness

Safety & Handling

• Environmental: LABSA is biodegradable due to its linear chain structure, making it eco-friendly.
• Eye Contact: Can cause severe irritation – rinse with water for at least 15 minutes.
• Skin Contact: Wash immediately with water and soap if exposed.
• Inhalation: Vapors may irritate the respiratory system – move to fresh air; administer oxygen if necessary.
• Ingestion: Rinse mouth thoroughly with water; seek medical attention.
• Storage:
  • Store in sealed containers, in a cool, dry, and ventilated area.
  • Keep away from heat, sparks, and open flames.
  • Always close containers tightly to minimize vapor release.
