Applications

Sulphonic Acid (LABSA 96%) is mainly used as:

1. Detergent & Cleaning Raw Material
   • Base surfactant for laundry powder, liquid detergents, dishwashing liquid and household cleaners.
   • Provides high detergency, strong foaming and good soil removal on textiles and hard surfaces.
2. Industrial & Institutional Cleaners
   • Component of carpet and floor cleaners, heavy-duty degreasers, car wash liquids and workshop cleaners.
   • Effective on oily and greasy contaminants in factories, workshops and garages.
3. Textile & Leather Industry
   • Used as a scouring, wetting and degreasing agent in textile pre-treatment to remove oils, waxes and sizing agents.
   • Emulsifier and wetting agent for leather degreasing and finishing formulations.
4. Paper & Pulp
   • De-inking agent and emulsifier in recycling and paper processing formulations.
5. Other Uses
   • Surfactant component in agrochemical formulations (to improve wetting and spreading of active ingredients).
   • Auxiliary surfactant in oilfield chemicals and various industrial emulsifier blends.

Storage Conditions

• Store in a cool, dry and well-ventilated warehouse, away from direct sunlight and heat sources.
• Recommended storage temperature: ambient to cool conditions; avoid long-term exposure to temperatures near or below its pour point to prevent solidification. For high-purity reference standards, 2–8 °C storage is typical.
• Keep containers tightly closed when not in use to avoid moisture uptake and contamination.
• Keep away from strong oxidizing agents, strong bases and reactive metals, as the product is strongly acidic and corrosive to many materials.
• Use acid-resistant tanks, lined drums or IBCs recommended by your engineering team for bulk storage.

Safety Precautions

Sulphonic Acid (LABSA) is a corrosive organic acid. Proper industrial handling procedures are required:

• Hazard characteristics
  • Strong acid, causes severe skin burns and serious eye damage.
  • Corrosive to many metals; reacts with bases and reactive metals with heat release.
• Personal protective equipment (PPE)
  • Wear acid-resistant gloves, long-sleeve protective clothing and closed shoes.
  • Use chemical splash goggles and/or face shield to protect eyes and face.
  • In poorly ventilated areas or when handling large quantities, use suitable respiratory protection according to your plant EHS rules.
• Handling advice
  • Avoid all contact with skin and eyes; do not breathe mist or vapors.
  • Always add acid to water slowly when preparing dilutions, not the other way around.
  • Provide local exhaust or general ventilation in filling and dosing areas
• First-aid (summary)
  • Skin contact: Immediately remove contaminated clothing and rinse skin with plenty of water for at least 15 minutes; seek medical attention.
  • Eye contact: Rinse cautiously with water for several minutes, holding eyelids open; remove contact lenses if easy, continue rinsing and get urgent medical help.
  • Inhalation: Move the person to fresh air, keep warm and at rest; seek medical attention if symptoms persist.
  • Ingestion: Rinse mouth, do NOT induce vomiting, and get immediate medical assistance.
