How does CAS 68439-57-6 differ from standard Linear Alkylbenzene Sulfonates (LAS) in industrial cleaning systems?

Unlike LAS, Sodium Alpha-olefin Sulfonate (CAS 68439-57-6) exhibits superior stability across a wide pH range and maintains high foaming performance in hard water conditions, making it the preferred choice for specialized industrial scouring and degreasing agents.

Is this material intended for use as a primary surfactant in heavy-duty industrial detergent formulation?

Yes, this industrial ingredient is typically applied as the core surfactant in aqueous formulations for vehicle cleaning, industrial pressure washing, and hard surface degreasing due to its high flash foam and emulsification properties.

Sodium Alpha-olefin Sulfonate CAS 68439-57-6

Sodium Alpha-olefin Sulfonate, identified by CAS 68439-57-6, is a high-performance anionic surfactant consisting primarily of sodium C14-16 olefin sulfonates. As a versatile sodium alpha-olefin sulfonate, this technical-grade alpha olefin sulfonate sodium salt functions as a primary foaming and emulsifying agent in various industrial detergent formulation processes. This sodium linear alpha-olefin sulfonate is valued for its hard water stability and rapid flash foam generation during heavy-duty cleaning cycles. Our facility provides competitive factory pricing and customized specifications for this material to ensure compatibility with specific manufacturing requirements. For procurement and technical validation, we offer comprehensive MSDS, TDS, COA documentation and support consistent bulk supply for large-scale operations.

Product Description

AOS is produced by sulfonation and neutralization of alpha-olefins, resulting in a high-performance anionic surfactant system (typically C14-16). It delivers rich foam, fast soil removal, good rinsability, and stable performance across a wide temperature range, making it suitable for household detergents, industrial cleaners, and some personal-care/handwash type formulations where robust cleansing and foam are needed.

Physicochemical Properties (Typical)

Typical values for common market grades. Final specs follow COA by batch.

Option A — AOS 92% Powder (Typical)

Item	Typical Specification
Appearance (25°C)	White / off-white to light yellow powder
Active matter (%)	≥ 92.0
Sodium sulfate (%)	≤ 3.0 (often controlled; may vary by plant/spec)
Unsulfonated matter (%)	controlled (typ. low; spec varies)
Free alkali (as NaOH, %)	≤ 0.9 (typical)
pH (1% aq. solution)	typically alkaline range (spec varies by plant)
Solubility	Soluble in water (formulation-dependent)

Option B — AOS 35% Liquid (Typical)

Item	Typical Specification
Appearance (25°C)	Colorless to pale yellow clear liquid
Active matter (%)	34.0–36.0
pH (10% solution)	~7.0–8.5 (typical market range)
Solubility	Completely miscible with water

Applications

Laundry detergents (powder & liquid): primary/secondary anionic surfactant
Dishwashing liquids: foam and grease removal
All-purpose & industrial cleaners: wetting, emulsification, soil suspension
Car wash / degreasers: rich foam and rinsability
Oilfield / specialty cleaning where robust foaming/wetting is required (formulation test recommended)

Storage Conditions

Store in cool, dry, well-ventilated warehouse, tightly sealed.
Keep away from strong oxidizers; avoid moisture ingress (powder is hygroscopic).
Recommended storage temperature: 5–35°C.
Stack and transport to prevent bag/drum damage; keep pallets clean and dry.
Typical shelf life: 12–24 months (subject to packaging and storage conditions).

Safety Precautions

Avoid contact with eyes and prolonged skin contact; wear gloves + goggles.
If dust may form (powder), use dust mask/respiratory protection and local ventilation.
Wash hands after handling; keep out of reach of children.
Spills are slippery—contain and clean promptly; prevent large releases to drains/waterways.
Typical SDS classifications for AOS products include skin/eye irritation warnings (follow the SDS for your supplied grade).
