Frequently Asked Questions

What is Lauramine Oxide used for?

Lauramine Oxide is an amphoteric amine-oxide surfactant used as a foam builder and stabilizer in dishwashing detergents, hard-surface cleaners, shampoos, and soaps. It also functions as a wetting agent, viscosity modifier, and antistatic ingredient in cleaning and personal-care formulations.

What is the source of Lauramine Oxide?

Lauramine Oxide (dodecyldimethylamine oxide, CAS 1643-20-5) is a synthetic surfactant built on a C12 (lauryl) chain typically derived from coconut or palm-kernel fatty alcohols. Feedstock origin varies by manufacturer; specify renewable-source or grade requirements on your RFQ.

What is the chemical formula for Lauramine Oxide?

Lauramine Oxide has the molecular formula C14H31NO and CAS number 1643-20-5. It is the amine oxide of N,N-dimethyldodecylamine and is supplied as an aqueous solution, typically around 30% active.

How is bulk Lauramine Oxide shipped?

Because it is supplied as an aqueous solution, Lauramine Oxide ships under UN 3249 (dimethyldodecylamine-N-oxide). RawSource supplies it in drums, totes, and IBC quantities; a current SDS and CoA accompany every shipment.

How do I get bulk pricing for Lauramine Oxide?

Pricing depends on active concentration, volume, and packaging (drum, tote, or IBC). Submit an RFQ with your target spec and annual volume for a current bulk quote and a CoA/SDS package.
