Frequently Asked Questions
What is sodium C14-16 olefin sulfonate used for?
Sodium C14-16 olefin sulfonate (CAS 68439-57-6), commonly alpha olefin sulfonate (AOS), is an anionic surfactant used as a foaming, wetting, and cleansing agent in shampoos, body washes, hand cleansers, and household and industrial cleaners. It offers good detergency and hard-water tolerance.
Is sodium C14-16 olefin sulfonate the same as sodium lauryl sulfate?
No. They are different anionic surfactants. Sodium C14-16 olefin sulfonate (AOS) is made by sulfonation of C14-16 alpha olefins, while sodium lauryl sulfate (SLS) is a sulfate ester of lauryl alcohol. They differ in chemistry, CAS number, and performance, though both are used as primary foaming surfactants.
How is sodium C14-16 olefin sulfonate produced?
It is produced by sulfonation of C14-16 alpha olefins, yielding the anionic AOS surfactant (CAS 68439-57-6). It is typically supplied as an aqueous solution. See the CoA for active content and the SDS for handling.
What is the CAS and HS code for sodium C14-16 olefin sulfonate?
It is CAS 68439-57-6, classified under HS 3402.39 (organic surface-active agents, anionic: other). These identifiers are documented on the CoA and shipping paperwork.
How is sodium C14-16 olefin sulfonate supplied and priced in bulk?
We supply AOS in industrial quantities with CoA and SDS per lot. Bulk pricing depends on active content, packaging, and volume; request a bulk quote for current pricing and lead time.
What is the REACH and TSCA regulatory status of Sodium C14-16 Olefin Sulfonate (Alpha Olefin Sulfonate, AOS)?
Sodium C14-16 Olefin Sulfonate (Alpha Olefin Sulfonate, AOS) (CAS 68439-57-6) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 931-534-0).
