Alpha Olefin Sulphonate, or α-Olefin sulfonates, commonly called AOS for short, is a third-generation anionic surfactant. It's biodegradable, mild, and resistant to hard water, yet with outstanding detergency and excellent compatibility with other types of surfactants. It's widely used to formulate high-foaming heavy-duty detergent as the secondary surfactant alone with Linear Alkyl Benzene Sulphonic Acid (LABSA) or to formulate mild light-duty detergents and personal care products, such as hand soap liquid, shampoo, baby bubble bath, and so on.
There are commonly two types of AOS commercially available, the liquid solution(with 33%-40% active matter content) and the dry powder(with 85%-95% active matter content). The choice of these two types is based on the formulation target, transporting and handling convenience, and cost.
Yeser Chemicals has been partnering with leading AOS manufacturers through a Third-party Toll-manufacturing Agreement. We can supply top-quality Yeser® AOS 35% solution and 92% powder at a competitive price, with a capacity of 5,000 MT/ Month.
Features & Benefits:
- Excellent solubility and compatibility with other surfactants, resulting in great formulating flexibility.
- Significant foaming, emulsifying, cleansing ability, and 100% biodegradability.
- Outstanding high-temperature stability, makes it the perfect surfactant for spray tower dried synthetic detergent.
- Outstanding hard water resistant property.
- Mild, low irritation to the skin.
Stability/Shelf life:
Stable at an extensive pH range and suitable for use in acidic and alkaline environments.
Pack in tight-closed containers(drums or tanks); Store in a dry, ventilated and cool place; Kept away from direct sun and water.
Under proper storage conditions, the shelf life of Yeser® AOS(Solution/ Powder) is 24 months.
Recommended dosage:
The recommended dosage of Yeser® AOS in detergents and personal care products is 2.0%-15.0%.

Frequently Asked Questions
We don’t produce Alpha Olefin Sulphonate (AOS) by ourselves, yet we are not simply trading it.
We have signed a Third-party Toll-manufacturing Agreement with a leading AOS manufacturer(a neighbor of our factory) who contract manufactures AOS for us, as per our demand and requirements.
Together with our contract manufacturer, Yeser Chemicals supplies top-quality Yeser® AOS at a competitive price, with a capacity of 8,000 MT/ Month.
AOS is a mild and low-irritation aonionic surfactant. It’s safe and good to use in personal care products, even baby care products.
Typically, our Minimum Order Quantity(MOQ) for AOS is one 20″FCL, which is 14MT(92% powder) or 16MT(35% solution).
However, we accept mixed loading with other non-hazardous products, such as CAPB, CDEA, SLES, AEO-9, etc.
