🏭 Main Applications
LABSA is one of the most important anionic surfactant intermediates:
- Neutralized with NaOH → LAS (Linear Alkylbenzene Sulfonate)
- Used in:
- Laundry powders & liquids
- Dishwashing liquids
- Industrial & institutional cleaners
- Emulsifiers and wetting agents
🧪 Production
- Produced by sulfonation of Linear Alkylbenzene (LAB) using:
- Sulfur trioxide (SO₃) in modern continuous processes
- Followed by aging and stabilization to achieve ~96% active content
⚠️ Safety & Handling
- Corrosive (strong acid)
- Causes severe skin burns and eye damage
- Reacts exothermically with alkalis during neutralization
- Handle with:
- Chemical-resistant gloves
- Goggles/face shield
- Adequate ventilation
🌱 Environmental Notes
- When neutralized to LAS, the product is:
- Readily biodegradable under aerobic conditions
- Widely accepted in detergent formulations globally
📊 Typical Specification (Indicative)
- Active matter: ≥ 96%
- Free oil: ≤ 2%
- Color (Klett): 30–80
- Sulfate: ≤ 1.5%
Linear Alkyl Benzene Sulphonic Acid, or LABSA for short, has been the world’s largest-volume synthetic surfactant used in the detergent industry for decades. It’s a very cost-effective anionic surfactant with excellent cleaning power and compatibility with other types of surfactants.
LABSA has been the dominant active matter of synthetic detergent powder since it was developed to become a biodegradable replacement for Nonlinear Alkyl Benzene Sulfonate (BAS). It can be stably dried into a powder form, and it can also easily dissolve in water to formulate many kinds of detergents in liquid and gel form, such as Dishwashing Liquid, Laundry Detergent Liquid, and Hand Soap Liquid.
Minglan Chemicals has been partnering with leading LABSA manufacturers through a Third-party Toll-manufacturing Agreement. We can supply top-quality ML® LABSA 96% at a competitive price, with a capacity of 8,000 MT/ Month.
Features & Benefits:
