Sodium Alkyl Benzene Sulphonate (LAS) is a highly effective anionic surfactant known for its strong detergency, powerful foaming capability, excellent emulsification, and outstanding compatibility with a wide range of formulation additives. It features low production cost, mature synthesis technology, and broad applications across the cleaning, chemical, and industrial fields.
Advantages of Sodium Alkyl Benzene Sulphonate
Cleaning Power
It helps lift dirt, oil, and grease from surfaces by encapsulating them into micelles that can be easily rinsed away with water.
01
Foaming Ability
It produces stable foam in aqueous solutions, which enhances the perceived effectiveness of detergents and personal care products like shampoos and body washes.
02
Emulsification
It enables the mixing of oil and water-based ingredients, crucial in products such as laundry detergents, dishwashing liquids, and industrial cleaners.
03
Cost-Effectiveness
Compared to other surfactants, it offers strong performance at a relatively low cost, making it a popular choice in mass-market formulations.
04
Synergy with Other Ingredients
It works well in combination with builders (e.g., zeolites), enzymes, and bleaching agents to boost overall cleaning efficiency.
05
Types of Sodium Alkyl Benzene Sulphonate
CAS 85117-50-5
A standardized form of sodium alkyl benzene sulfonate identified by its Chemical Abstracts Service (CAS) number 85117-50-5. This variant is recognized for its consistent surfactant performance and regulatory compliance.
SAS-60 (60% Active)
A concentrated liquid form containing 60% active sodium alkyl benzene sulfonate. Its high concentration makes it ideal for industrial and heavy-duty cleaning applications.
SAS-40 (40% Active)
A lower-concentration variant with 40% active ingredients, offering easier handling and formulation flexibility. It is commonly used in fabric processing and lighter-duty cleaning applications.
Linear Alkyl Benzene Sulfonate (LAS)
Derived from linear alkyl benzene, this eco-friendlier variant is highly biodegradable and widely used in modern detergent formulations.
Cyclic (Branched) Alkyl Benzene Sulfonates
These older-generation sulfonates contain branched alkyl chains, offering strong cleaning power but with environmental drawbacks due to poor biodegradability.
Sulfobetaine Derivatives
Zwitterionic surfactants created by modifying betaine structures with sulfonic acid groups. These offer unique surface activity and compatibility.
Applications of Sodium Alkyl Benzene Sulphonate
Detergents and Cleaners
As a primary surfactant, SABS lowers the surface tension between water and oils, enabling water to penetrate and lift away grease, dirt, and organic residues more effectively.
Textile Industry
In textile manufacturing, sodium alkyl benzene sulfonate functions as a wetting agent and dispersant during critical stages such as dyeing, scouring, and finishing.
Agricultural Formulations
Sodium alkyl benzene sulfonate is a crucial ingredient in agrochemical formulations, particularly in emulsifiable concentrates (ECs) of pesticides, herbicides, and fungicides. It acts as an emulsifier and dispersing agent, allowing hydrophobic active ingredients to mix uniformly with water in spray tanks.
Oil and Gas Extraction
It reduces interfacial tension between oil, water, and gas phases, facilitating the separation and flow of crude oil from reservoirs—especially in enhanced oil recovery (EOR) techniques like surfactant flooding.
Personal Care Products
Although less common than other sulfonates like sodium lauryl sulfate, sodium alkyl benzene sulfonate can be found in certain personal care products due to its foaming, emulsifying, and thickening properties.
Paper and Pulp Industry
It aids in breaking down lignin and other non-cellulosic materials in wood chips, improving the efficiency of chemical pulping operations such as kraft or sulfite processes.
Molecular Formula: While the exact structure can vary based on the alkyl chain length, it is commonly represented as C₁₈H₁₉NaO₃S, composed of carbon, hydrogen, oxygen, sodium, and sulfur atoms.
Molecular Weight: Approximately 330.41 g/mol, which influences solubility and formulation compatibility.
Active Content: Typically ranges from 30% to 70%, depending on the grade and manufacturing process. Higher concentrations are used in industrial formulations, while lower ones suit consumer products.
PH (1% Solution): Generally between 7.0 and 10.0, indicating mild alkalinity. This makes it suitable for most cleaning applications without causing excessive corrosion.
Boiling Point
Not precisely defined due to decomposition before boiling. However, it demonstrates good thermal stability under normal processing conditions.
Solubility
Highly soluble in water, forming stable micellar solutions. It has limited solubility in non-polar organic solvents like hexane or toluene.
Note
Always refer to the Safety Data Sheet (SDS) for precise handling and compatibility information.
Fresh Preparation: Prepare solutions of SABS just before use whenever possible. Pre-diluted solutions may lose potency over time due to microbial growth or hydrolysis, especially in warm or humid conditions.
Precise Concentration: Follow formulation guidelines closely to achieve the desired concentration. Under-dosing reduces cleaning efficiency, while overdosing can lead to excessive foaming or residue buildup.
Thorough Mixing: When blending SABS with other ingredients, ensure complete dispersion using appropriate agitation. For powders, gradually add to water with stirring to prevent lump formation. For liquids, use mechanical mixers to achieve homogeneity.
Water Quality: Use deionized or softened water when preparing SABS solutions, as hard water containing calcium and magnesium ions can reduce its effectiveness by forming insoluble salts.
Safe and Effective Handling Practices
Personal Protective Equipment (PPE)
Always wear chemical-resistant gloves, safety goggles, and a dust mask or respirator when handling powdered SABS. For liquid forms, protective clothing and face shields may be necessary to prevent splashes.
Dust Suppression
When using powdered SABS, work in a well-ventilated area or use local exhaust ventilation. Avoid dry sweeping or using compressed air, which can aerosolize fine particles. Instead, use wet cleaning methods or HEPA-filtered vacuums for cleanup.
Spill Response Protocol
In case of spills, immediately contain the area. For solids, dampen the spill with water and collect using non-sparking tools. For liquids, absorb with inert materials like sand or vermiculite.Dispose of waste according to local environmental regulations.
Static Control
Powdered SABS can generate static electricity during transfer. Use grounded equipment and conductive containers to prevent static buildup, which could pose a fire or explosion risk in certain environments.
Optimal Storage Conditions
Temperature Control
Store SABS at stable room temperature (ideally between 15°C and 25°C / 59°F to 77°F). Exposure to extreme heat can accelerate degradation, leading to discoloration or reduced surfactant activity. Conversely, freezing temperatures may cause phase separation in liquid forms or increased brittleness in solid forms.
Humidity Management
Solid SABS formulations are hygroscopic and prone to caking or clumping in high-humidity environments. Always store in a dry, climate-controlled area with relative humidity below 60%. Liquid forms are less sensitive to humidity but should still be protected from condensation that could dilute the product.
Airtight Sealing
Use sealed, airtight containers made of compatible materials (e.g., high-density polyethylene or stainless steel). This prevents moisture absorption, contamination from airborne particles, and potential chemical reactions with atmospheric gases. Ensure lids are tightly closed after each use.
Light Protection
Although SABS is relatively stable, prolonged exposure to direct sunlight or UV radiation may contribute to gradual degradation. Store in opaque containers or in dark, shaded areas to maximize shelf life.
