Chemical Profile of Coco Betaine
Molecular Structure and Origin
Coco Betaine (chemically known as cocamidopropyl betaine) is synthesized through the reaction of:
- Coconut oil fatty acids (providing the hydrophobic tail)
- Dimethylaminopropylamine (DMAPA)
- Sodium monochloroacetate
This creates an amphoteric surfactant with:
- Positive charge at low pH (cationic behavior)
- Negative charge at high pH (anionic behavior)
- Neutral charge at its isoelectric point
