Alpha Olefin Sulphonate (AOS)
Exporter & supplier, HSN 340239, Surfactants
Alpha olefin sulphonate (AOS) is an anionic surfactant made from C14–16 alpha olefins. It foams well in hard water, stays stable across a wide pH range and biodegrades readily, making it a common sulphate-free alternative to SLES and SLS.
Also known as: AOS, Sodium C14-16 olefin sulphonate, Sodium C14-16 olefin sulfonate, Sodium alpha olefin sulfonate, Olefin sulphonate

Handling, storage and hazards
Handling and storage
- Store liquid AOS between about 5 °C and 40 °C in closed containers; it is more cold-stable than SLES 70% paste.
- Store powder dry and minimise dust when handling.
- Use clean equipment; solutions should be preserved against microbial growth once opened.
- Wear eye protection and gloves during handling.
Hazards
- Causes serious eye damage, both as powder and in typical 35–40% solutions.
- Causes skin irritation.
- Harmful to aquatic life before dilution.

Questions about Alpha Olefin Sulphonate (AOS)
Is AOS a sulphate-free surfactant?
Yes. AOS is a sulphonate, not a sulphate, so it is widely used in products labelled sulphate-free.
How does AOS compare with SLES?
AOS gives quick, abundant foam and tolerates hard water better, but it thickens less readily with salt. Many formulas combine the two or add a co-surfactant such as cocamidopropyl betaine.
Why is AOS used in foamed concrete?
Because it produces fine, stable bubbles that survive mixing with cement, giving lightweight concrete and gypsum products a uniform cell structure.
What HSN code does AOS use?
Alpha olefin sulphonate falls under HSN 340239, other anionic organic surface-active agents.
Is an SDS available for AOS?
Yes, an SDS is available on request.
Do you export Alpha Olefin Sulphonate (AOS)?
