What is Linear Alkylbenzene Sulfonate CAS 126-66-9

Linear Alkylbenzene Sulfonate (LAS), CAS 126-66-9, is a widely used anionic surfactant known for its excellent cleaning and emulsifying properties. It is a key detergent raw material in household and industrial cleaning products, prized for its strong grease-cutting ability and cost-effectiveness. LAS is commonly found in various formulations such as liquid detergents, laundry powders, and dishwashing liquids.

This surfactant is derived from Linear Alkylbenzene (LAB), making it more biodegradable and environmentally friendly compared to branched-chain analogs. Because of its biodegradable detergent nature, LAS has become a preferred choice in the US market for consumers and manufacturers aiming for high-performance cleaning with reduced environmental impact.

Chemical Composition and Structure of Linear Alkylbenzene Sulfonates

Molecular formula: Typically represented as C₆H₄(CH₂)nSO₃Na
Structure: LAS consists of a linear alkyl chain attached to a benzene ring bearing a sulfonate (-SO₃) group, linked as a sodium salt.
The linear alkyl chain varies in length, usually between C10 to C14, influencing its surfactant properties and performance.
The anionic charge on the sulfonate group makes LAS effective in lowering surface tension and dispersing oils and dirt.

Because of its linear structure, LAS has improved biodegradability compared to branched alkylbenzene sulfonates, making it an environmentally preferable LAS surfactant with consistent cleaning ability.

Production Process of Linear Alkylbenzene Sulfonate

Step 1: Alkylation

LAB is synthesized by alkylation of benzene with long-chain mono-olefins under acidic catalyst conditions. This process results in a linear alkylbenzene with consistent chain length and distribution.

Step 2: Sulfonation

The LAB undergoes sulfonation using sulfur trioxide or chlorosulfuric acid to introduce the sulfonic acid group (-SO₃H).

Step 3: Neutralization

The sulfonated product is neutralized with sodium hydroxide (NaOH) to form the sodium salt, producing the final sodium dodecylbenzene sulfonate (the main LAS component).

Quality control is critical throughout to ensure consistent purity, effective surfactant properties, and low levels of impurities.

Blissam uses advanced catalytic processes ensuring a reliable, high-quality supply of LAS compliant with US regulatory and environmental standards.

Environmental and Safety Considerations for Linear Alkylbenzene Sulfonate CAS 126-66-9

Biodegradability of LAS Surfactant

Linear Alkylbenzene Sulfonates (LAS) are recognized as readily biodegradable anionic surfactants. Unlike their branched counterparts, LAS breaks down efficiently in wastewater treatment plants and natural environments. This biodegradability helps reduce the buildup of persistent pollutants, making LAS surfactant a preferred choice for eco-friendlier detergent formulations in the household and industrial cleaning sectors.

Environmental Impact

While LAS is biodegradable, it’s important to understand its interaction with aquatic ecosystems. At recommended usage levels, LAS exhibits low toxicity to aquatic life and does not bioaccumulate significantly. However, improper disposal or excessive discharge can temporarily impact water quality due to surfactant activity affecting aquatic organisms. Manufacturers and users alike must ensure adherence to environmental regulations to minimize potential negative effects.

Safety and Handling Guidelines

When dealing with Linear Alkylbenzene Sulfonate CAS 126-66-9, safety is critical. LAS is an anionic surfactant that can cause irritation upon direct skin or eye contact. Here are some important points for safe handling:

Use personal protective equipment such as gloves and safety goggles.
Avoid inhalation of dust or mist during handling.
Store in a cool, dry, and well-ventilated area to prevent degradation.
Follow local regulations for disposal of surfactant residues and containers.

Proper adherence to these safety practices ensures a safer working environment without compromising product performance.

Linear Alkylbenzene Sulfonate CAS 126-66-9 offers a balanced solution with strong cleaning power, excellent biodegradability, and manageable environmental impact when used responsibly. This makes LAS surfactant an excellent raw material choice for U.S.-based formulators focused on sustainability and safety in their detergent and cleaning product lines.
