What is Dodecylamine?
Dodecylamine (CAS 124-22-1), also known as Laurylamine, is a long-chain primary amine.
Where is Dodecylamine used?
- Surfactant manufacturing: building block for cationic and amphoteric surfactants
- Corrosion inhibitors and flotation agents: component
- Mineral processing: collector agent in froth flotation, selectively binding to silica and oxide mineral surfaces to enable ore separation
- Epoxy systems: curing agent and crosslinker improving adhesion and mechanical performance in coatings and adhesives
- Personal care: intermediate in the synthesis of quaternary ammonium compounds and amine oxides for conditioning and cleansing formulations
- Plastics: surface modifier for fillers and pigments, improving dispersion and compatibility within polymer matrices
Commercial specifications
- Purity levels typically ranging from 95% to 99%+
- Bulk quantities in drums and IBCs
