Alpha olefin is a powder of various shades, from white to yellowish, odorless. Resistant to acidic and alkaline environments. When mixed with water, it is not demanding on water hardness or pH.
Alpha olefin sulfonates are produced by sulfonation with sulfur trioxide, followed by alkaline hydrolysis. Sodium sulfonate is highly soluble in water. It is a widely used anionic surfactant. The main advantage of AOS is that it does not irritate the skin, foams well, and is bio-neutral for the environment (it decomposes on its own into substances that are not hazardous to nature). AOS also forms stable emulsions, which is actively used in the cosmetics industry. Combined with its mild effect on human skin, this substance is suitable even for people with sensitive skin.

Sodium alpha-olefin sulfonate is an anionic surfactant, which in technical documentation may be designated as AOS, Sodium Alpha-Olefin Sulfonate, or sodium alpha-olefin sulfonate. When purchasing, it is important to check not only the name but also the CAS number, appearance, mass fraction of active substance, moisture content, free alkali content and accompanying salts. This helps avoid confusion between similar trade names and select the product for a specific enterprise formulation.
When purchasing sodium alpha-olefin sulfonate, attention is primarily paid to the mass fraction of active substance, water content, free alkali, sodium sulfate and non-sulfated matter. These parameters affect batch stability, solubility, foaming, colour and the product’s behaviour in the finished mixture.
Sodium alpha-olefin sulfonate dissolves well in water, but for a stable working solution it is best introduced gradually, with stirring, avoiding the formation of dense lumps. Under production conditions, water temperature, concentration, stirring speed and the order of adding other components are taken into account. If the product is used in a formulation, it is important to control the clarity or homogeneity of the solution, the absence of undissolved particles and compatibility with the other substances according to the process chart.
Sodium alpha-olefin sulfonate is stored in sealed factory packaging, in a dry warehouse, protecting the product from moisture and overheating. If it gets wet, the powder can cake, become harder to dose and dissolve unevenly, which creates problems when preparing working mixtures. For a wholesale batch it is important to preserve the labelling, quality certificate and traceability from receipt through to transfer into production. Bags should be placed on pallets, avoiding contact with a wet floor and packaging damage.
