What is Dimethyloctylamine?
Dimethyloctylamine (CAS 7378-99-6), also known as DMOA, is a tertiary aliphatic amine.
Where is Dimethyloctylamine used?
- Industrial and household cleaning: neutralizing agent for anionic surfactants, improving detergent stability at target pH ranges
- Personal care: intermediate in the synthesis of quaternary ammonium compounds and amine oxides for conditioning and mild cleansing products
- Textile and leather processing: wetting and penetration of treatment baths for even distribution of dyes and finishing agents
- Paper chemicals: sizing and surface treatment formulations requiring controlled alkalinity
- It functions as a pH regulator and surface-active intermediate.
Commercial specifications
- Bulk supply in drums and IBC containers, with quantities suited to development and production
