What is Dimethyloctadecylamine?
Dimethyloctadecylamine (CAS 124-28-7), also known commercially as Dimantine, is a long-chain tertiary amine used as a building block for cationic surfactants and corrosion inhibitors.
Where is Dimethyloctadecylamine used?
- Lubricants and metalworking fluids: corrosion inhibitor and boundary lubricant additive forming protective films on metal surfaces
- Personal care: quaternization yields fabric softeners, hair conditioning agents and antistatic compounds
- Mineral processing: flotation collector intermediate
- Coatings and asphalt: emulsifier production
- Its C18 fatty chain structure makes it a preferred intermediate where controlled surface activity is required.
Commercial specifications
- Technical grade, purity commonly 95% to 99%
- Drums, IBCs and bulk tanker quantities
