Frequently Asked Questions

What is amine oxide used for?

Amine oxides such as stearamine oxide (CAS 2571-88-2) are used as foam boosters, mild cleansing surfactants, hydrotropes/solubilizers, and conditioning/antistatic agents. Stearamine oxide is the C18 (stearyl) member of this surfactant class. It is supplied as a raw material for formulation.

What is an alternative to stearamine oxide in the amine-oxide class?

Other amine-oxide surfactants differ by alkyl chain length, lauramine oxide (C12) and myristamine oxide (C14) are shorter-chain alternatives with different foaming and solubility profiles. Stearamine oxide's longer C18 chain gives it distinct conditioning and viscosity behavior. The right choice depends on the target system; we can quote the appropriate grade.

What is the chemical identity of stearamine oxide?

Stearamine oxide is N,N-dimethyloctadecylamine N-oxide, CAS 2571-88-2, molecular formula C20H43NO. It is an amine-oxide surfactant. CoA documents assay and active content per lot.

Is stearamine oxide an ionic or nonionic surfactant?

Amine oxides are classified as amphoteric: they are essentially nonionic at neutral and alkaline pH and become cationic under acidic conditions. This pH-dependent behavior is why they pair well with anionic surfactants for foam boosting and viscosity building.

How is bulk stearamine oxide packaged?

RawSource supplies stearamine oxide in drums, totes, and other industrial packaging for manufacturers. MOQ and lead time depend on grade and volume. Request a bulk quote; CoA and SDS accompany each shipment.
