Applications

1. Direct Precursor To Amine Oxide Surfactants: The direct precursor to lauryldimethylamine oxide, the C12 amine oxide used as a foam booster and viscosity builder in hand dishwashing liquids, shampoos and hard surface cleaners, where it also brings thickening, antistatic and conditioning performance.

2. Feedstock For Quaternary Ammonium Compounds: Reacts with dimethyl sulfate or diethyl sulfate to give the cationic quaternary ammonium salts, and downstream products built from it include dodecyltrimethylammonium chloride and benzyldodecyldimethylammonium bromide for cleaning agents and cosmetics.

3. Building Block For Betaine Amphoteric Surfactants: A tertiary amine building block for betaine type amphoteric surfactants, which are used in personal care and industrial cleaning where an amphoteric surfactant has to perform alongside other surfactant classes.

4. Route To Ethoxylated Amine Nonionic Surfactants: Reacts with ethylene oxide to give ethoxylated amine nonionic surfactants, carrying the same C12 chain into the nonionic surfactant family used in emulsification, wetting and antistatic work.

5. Downstream Cleaning, Cosmetic And Conditioning Applications: The quaternary ammonium salts, amine oxides and betaines built from it are the cationic and amphoteric actives behind cleaning agents, cosmetics, hair conditioning and antistatic products.
