For B2B procurement and formulation scientists, a deep understanding of raw material specifications is crucial for successful product development. Alpha Olefin Sulfonate (AOS), identified by CAS number 68439-57-6, is a high-performance anionic surfactant that demands precise quality control. As a prominent supplier of Alpha Olefin Sulfonate, we are committed to providing transparent and detailed information about our products, enabling our clients to make informed purchasing decisions.

Our AOS is available in two primary forms: a concentrated 92% powder and a readily usable 35% liquid. Both grades are manufactured under stringent quality protocols to ensure consistency and superior performance. When you choose to buy AOS surfactant from us, you are guaranteed a product that adheres to industry-leading standards.

The specifications for our Alpha Olefin Sulfonate are designed to meet the diverse needs of our clientele:

  • Appearance: Our 92% grade presents as a white or light yellow powder, while the 35% grade is a light yellow liquid. This variation in appearance is typical for AOS and does not affect its functional performance.
  • Active Matter Content: The 92% powder grade boasts an active matter content of ≥92%, ensuring maximum surfactant efficacy. The 35% liquid grade offers a stable 35.0±1% active matter content.
  • Petroleum Ether Soluble Substances: These impurities are kept to a minimum, with ≤3.0% for the powder and ≤1.5% for the liquid, indicating high purity.
  • Inorganic Salts: Similarly, inorganic salt content is controlled at ≤5.0% for the powder and ≤1.5% for the liquid, contributing to product stability and preventing unwanted side reactions in formulations.
  • Free Alkalinity: The free alkalinity is managed to be ≤1.0% for the powder and ≤0.3% for the liquid, crucial for maintaining product stability and preventing corrosion.
  • Water Content: The powder form contains ≤3.0% water, while the liquid form’s water content is typically not specified as it is the solvent base.
  • pH Value (1% aq. solution): Both grades exhibit an alkaline pH, typically between 9.5-11.5, which is characteristic of AOS and beneficial for many cleaning applications.
  • Whiteness (WG) / Color (Hazen): The powder grade shows a whiteness of ≥60, and the liquid grade has a color of ≤60 Hazen, both indicating good visual quality.

These specifications are critical for formulators working with AOS in personal care products, detergents, and industrial cleaning solutions. Understanding these parameters helps in predicting performance, ensuring compatibility, and optimizing formulations for specific applications.

As a reliable manufacturer and supplier in China, we are dedicated to providing Alpha Olefin Sulfonate that consistently meets or exceeds these quality benchmarks. Whether you require bulk quantities of the powder or liquid form, we are equipped to meet your demands. For those looking to secure a consistent supply of high-quality AOS for their operations, reaching out to our sales team for pricing and sample requests is the first step towards a successful partnership.
