Sodium Alkylbenzene Sulfonate CAS 68411-30-3

What is sodium alkylbenzene sulfonate?

Sodium Alkylbenzene Sulfonate, also known as Linear Alkylbenzene Sulfonate (LAS), is produced through a sophisticated process involving sulfonation and extraction.It has a corrosion inhibitory effect on metals and exhibits excellent emulsification and rust prevention properties. It is an anionic surfactant widely used in detergents, cleaning chemicals, and industrial formulations. It features powerful emulsifying, wetting, dispersing, and foaming properties, making it a preferred surfactant in household and industrial cleaning products.

Applications of Sodium Alkylbenzene Sulfonate (HABS)

Sodium alkylbenzene sulfonate (HABS) is widely used across multiple industrial sectors due to its strong hydrophobicity, excellent emulsifying, dispersing, and wetting abilities, and good resistance to hard water and alkaline environments.

1. Oilfield Tertiary Oil Recovery

Used as a key surfactant additive in enhanced oil recovery (EOR) processes. HABS improves crude oil fluidity, reduces interfacial tension, and enhances oil–water emulsification efficiency to significantly increase oil extraction rates.

2. Lubricating Oils & Anti-Rust Oils

Applied in the formulation of lubricating oils, anti-rust oils, and emulsified oils. It functions as an emulsifier and corrosion inhibitor, helping form stable protective films on metal surfaces and improving oil dispersion stability.

3. Metalworking Fluids

Serves as an emulsifying and wetting component in emulsified cutting fluids, wire-cutting fluids, and hydraulic transmission fluids. It enhances lubrication, cooling, and chip-removal performance, ensuring smoother machining and longer equipment life.

4. Industrial & Workshop Cleaning Agents

Commonly used in industrial degreasing agents, workshop detergents, and oil-removal cleaning solutions. HABS effectively dissolves grease and particulate contaminants, delivering fast detergency and rich, stable foam.

5. Textile Printing & Dyeing

Acts as a multifunctional textile auxiliary, including refining agent, desizing agent, and leveling agent. It improves fiber penetration, removes impurities and sizing, assists dye dispersion, and ensures uniform dyeing results.

6. Papermaking Industry

Used as a resin dispersant and felt cleaning agent in papermaking processes. It prevents resin agglomeration, enhances pulp dispersion, and cleans papermaking felt to maintain paper machine efficiency.

7. Leather Processing

Works as a penetrating and degreasing agent in leather processing. HABS promotes deep fiber penetration, emulsifies fats, and facilitates uniform degreasing, improving softness and finish quality of leather goods.

Key Features of Sodium Alkylbenzene Sulfonate (HABS)

1. Strong Hydrophobicity & Superior Interfacial Activity

Thanks to its higher-carbon alkyl chain structure (typically C₁₈–C₂₈), HABS delivers much stronger hydrophobicity and interfacial performance than conventional sodium dodecylbenzene sulfonate (LAS). This long-chain structure allows for more efficient oil–water interface reduction, improved penetration, and enhanced emulsification in heavy-duty systems.

2. Excellent Surface Activity

HABS offers multifunctional surface-active properties essential for industrial applications, including:

• Significant surface tension reduction

• Powerful emulsifying and detergency performance

• Effective dispersing and wetting abilities

• Stable high-foam generation and foam persistence

3. Strong Formulation Compatibility

Compatible with most anionic and nonionic surfactants, allowing flexible formulation combinations. This enhances system performance in oilfield chemicals, metalworking fluids, industrial cleaners, and textile auxiliaries.

4. High Solubility in Water & Alkaline Systems

Dissolves readily in water and alkaline media, ensuring fast dispersion and stable solution behavior across a wide pH range.

5. Hard Water & Alkali Resistance

Provides superior resistance to hard-water ions and alkaline conditions, maintaining high cleaning and emulsification efficiency—ideal for oilfield enhanced oil recovery, degreasing fluids, and industrial detergents.

6. Corrosion Inhibition & Anti-Rust Function

In addition to its core surfactant functions, HABS also demonstrates corrosion-inhibiting and rust-preventive properties, making it suitable for applications in rust-proof oils, lubricants, and metal processing chemicals.
