What is Dimethylhexadecylamine?
Dimethylhexadecylamine (CAS 112-69-6), also known commercially as Dimethyl palmitamine, is a long-chain tertiary amine derived from palmitic acid.
Where is Dimethylhexadecylamine used?
- Lubricants and metalworking: corrosion inhibitor precursor and lubricity additive that improves metal surface protection in cutting fluids and rust-preventive coatings
- Personal care: conditioning agent, emulsification aid and conditioning intermediate in creams and lotions
- Quaternization produces cationic surfactants for fabric softeners, hair conditioners and rinse-off products
- Mineral processing: flotation collector for silicate and oxide ores
- It selectively modifies mineral surfaces to aid separation.
Good to know: These applications rely on its substantivity to negatively charged surfaces.
Commercial specifications
- Liquid or low-melting solid, depending on ambient temperature and purity grade
- Technical grade standard; high-purity grades for specialty chemical synthesis
- Drum and IBC quantities
