Alpha Olefin Sulfonate (AOS) 35% Bulk Supplier

Niran Bio supplies Alpha Olefin Sulfonate (AOS) 35% for personal care, household cleaning, and industrial detergent applications. This liquid-grade anionic surfactant offers strong foam performance, effective detergency, and good compatibility with various surfactant systems.

Compared with high-active powder grades, AOS 35% is easier to handle in liquid production systems and is widely used in shampoos, body washes, dishwashing liquids, and multipurpose cleaners.

Niran Biochemical can provide technical and quality documentation including COA, MSDS, TDS, specification sheets, and relevant compliance documents to support sourcing and product evaluation.

What Is Alpha Olefin Sulfonate (AOS) 35%?

Alpha Olefin Sulfonate 35% is a liquid anionic surfactant derived from alpha olefins through sulfonation and neutralization processes. It combines strong cleansing ability, rich foam generation, and relatively mild skin feel compared with many conventional sulfate surfactants.

With approximately 35% active matter, AOS-35 is designed for direct use in liquid formulations, reducing dissolution time and simplifying manufacturing processes.

It also shows excellent compatibility with amphoteric and nonionic surfactants, allowing formulators to optimize foam texture, viscosity, and overall product stability.

FAQs

Why is Alpha Olefin Sulfonate 35% widely used in liquid detergents?

AOS 35% is supplied in liquid form, making it easier to pump, mix, and incorporate directly into liquid production systems.

Does Alpha Olefin Sulfonate 35% produce stable foam?

Yes. It generates rich and long-lasting foam with good stability in both soft and hard water conditions.

Can Alpha Olefin Sulfonate 35% improve viscosity in formulations?

Yes. AOS 35% can help build viscosity when formulated with suitable co-surfactants and salt systems.

What is the difference between Alpha Olefin Sulfonate 35% and SLES?

AOS 35% generally offers better hard water resistance and lower irritation potential compared with many SLES-based systems.

What is the difference between low-active and high-active Alpha Olefin Sulfonate?

Low-active Alpha Olefin Sulfonate grades such as 35%, 38%, and 40% are typically supplied as liquids for direct use in liquid formulations. High-active grades such as 90% and 92% are usually supplied in needle or powder form with lower water content, making them more suitable for concentrated formulations and reducing transportation and storage costs.
