linear alkylbenzene sulfonic acid(LABSA)

Linear Alkylbenzene Sulfonic Acid is one of the most versatile anionic surfactants in various industries. Renowned for their excellent cleaning, emulsifying, and wetting properties, LABSA is a core ingredient in soaps, detergents, industrial cleaners, and other chemical formulations. Its low cost, biodegradability in nature, and high-performance characteristics make it one of the most sought-after products in the global chemical market.

What Is LABSA?

LABSA is a dark brown, viscous liquid with high water solubility. It is prepared by the sulfonation of Linear Alkylbenzene, which is prepared by the alkylation of benzene with long-chain alkenes. Linear alkylbenzene sulfonic acid is used mainly in the manufacture of Linear Alkylbenzene Sulfonates, major active ingredients in detergents and cleaning agents.

Properties of LABSA

Linear Alkylbenzene Sulfonic Acid is a dark brown, viscous liquid with excellent water solubility and high surface activity. Some of its key properties include:

• Chemical Composition: Derived from linear alkyl benzene, giving it strong grease-cutting capabilities.
• Water Solubility: Easily dissolves in water, forming stable emulsions, even in hard water conditions.
• Surface Activity: Lowers water’s surface tension, making it an effective cleaning agent.
• Biodegradability: Environmentally friendly due to its easy breakdown in nature.
• Reactivity: Reacts with bases to form Linear Alkylbenzene Sulfonate (LAS), a crucial ingredient in detergent production.

Due to its efficiency and affordability, Linear Alkylbenzene Sulfonic Acid remains an essential component in formulating sustainable and high-performance cleaning products.

Production Process of linear alkyl benzene sulfonic acid

1. The production of LABSA involves a three-step process:

   1. Alkylation of Benzene

   Benzene reacts with long-chain alkenes (C10–C14) using catalysts such as HF (hydrofluoric acid) or AlCl₃ (aluminum chloride) to produce Linear Alkylbenzene (LAB).

   2. Sulfonation

   The Linear Alkylbenzene (LAB) undergoes sulfonation using sulfur trioxide (SO₃), forming crude LABSA.

   3. Neutralization & Purification

   The crude LABSA is neutralized with a base (such as NaOH) to create Linear Alkylbenzene Sulfonate (LAS). Impurities are removed to achieve industry-grade purity levels, typically available in 96%, 90%, and 85% grades.

Various Grades of LABSA

Linear alkylbenzene sulfonic acid is available in three primary grades to match application needs:

Application and Uses of Linear Alkylbenzene Sulfonic Acid (LABSA)

1. Detergent Manufacturing

• LABSA has become an indispensable ingredient in liquid and powder detergents, such as laundry detergents and dishwashing liquids. With its great emulsification, grease, dirt, and stubborn stains can be removed without compromising the high class of washing efficiency and product consistency.

2. Industrial Cleaning Agents

• Due to its strong grease-cutting abilities, LABSA finds wide applications in industrial cleaners, degreasers, and heavy-duty surface cleaners. It is a must-have chemical in any industrial cleaning formulation due to its excellent solubility, reasonable cost, and assured performance.

3. Textile Industry

• LABSA in textiles is a wetting and dispersing agent, enhancing dye penetration, fabric uniformity, and color distribution in high-quality fabric production. Multifunctional benefits also improve manufacturing efficiency and reduce operational challenges.

4. Personal Care Products

• Neutralized to LAS, LABSA is used in shampoos, body washes, and face cleaners for rich foam, deep cleaning, and high cleaning power. Its low-cost formulation, environmental acceptability, and consistent surfactant characteristics are preferred.

5. Agricultural Pesticides and Herbicides

• LABSA acts as an efficient dispersant in agrochemicals, wherein pesticides, herbicides, and fertilizers must be evenly spread on the surface of plants. Its excellent solubility, emulsifying ability, and environmental safety make it trustworthy in industry formulations.

6. Paper and Pulp Industry

• LABSA, which is used in producing paper and pulp, helps disperse fibers and additives to maintain homogeneity and quality in the final product. This results in better process efficiency coupled with product performance.

Packing of linear alkylbenzene sulfonic (LABSA)

LABSA is packaged to maintain its stability and prevent leakage during transportation. Common options include:

• Bulk Tankers for large-volume industrial supplies.
• 1000-liter IBC Tanks for medium-scale usage.
• 200–250 kg Drums for smaller, manageable quantities.

Conclusion

Linear Alkylbenzene Sulfonic Acid (LABSA) remains an indispensable surfactant in numerous industries due to its exceptional cleaning efficiency, cost-effectiveness, and biodegradability. With its widespread applications in detergents, industrial cleaners, textiles, and personal care products, LABSA continues to be a fundamental ingredient in the global chemical market. For premium-quality LABSA, ensure you source from reliable manufacturers that meet industry standards.
