Introduction

LABSA (Linear Alkyl Benzene Sulphonic Acid) is a cornerstone of modern industrial chemistry, widely recognized for its role in manufacturing detergents and cleaning agents. As a leading surfactant, LABSA combines cost-efficiency with high performance. ZÜMRÜT International Kimya Co. specializes in delivering premium-grade LABSA for global industries. This guide explores its properties, applications, and best practices.

What is LABSA?

LABSA, or Linear Alkyl Benzene Sulphonic Acid, is an organic sulfonic acid derived from the sulfonation of Linear Alkyl Benzene (LAB). This anionic surfactant is prized for its ability to reduce surface tension, making it indispensable in detergent formulations. Its versatility extends to emulsification, wetting, and foaming applications across industries.

Key Properties of LABSA

LABSA possesses several unique chemical and physical properties that make it an essential ingredient in many industrial formulations:

• Appearance: Brown to dark amber viscous liquid

• Solubility: Completely soluble in water

• Acid Value: Typically ranges between 210 – 240 mg KOH/g

• Active Matter: Approximately 90% (LABSA 90%)

• Biodegradability: Readily biodegradable, making it environmentally friendly

• Stability: Stable under normal storage and handling conditions

These features make LABSA suitable for applications where strong cleaning performance is required without harming the environment.

Production Process of Linear Alkylbenzene Sulfonic Acid

1. The production of Linear Alkyl Benzene Sulphonic Acid 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

• Linear Alkyl Benzene Sulphonic Acid 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

• Linear Alkyl Benzene Sulphonic Acid 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

• Linear Alkyl Benzene Sulphonic Acid, 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.

Packaging and Storage Guidelines

Packaging

ZÜMRÜT International Kimya Co. supplies LABSA in corrosion-resistant HDPE drums or IBC tanks (1000L). Custom packaging options ensure safe transit.

Storage

Store Linear Alkyl Benzene Sulphonic Acid in cool, dry areas away from direct sunlight. Ensure containers are tightly sealed to prevent moisture absorption, which can degrade quality.

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.
