Summary
This branched diamine surfactant combines a dodecyloxypropyl hydrophobic chain with a 1.3-diaminopropane hydrophilic group, offering unique cationic functionality. Its applications span personal care, textiles, and industrial formulations, where its film-forming, chelating, and crosslinking properties are valued. Proper PPE is essential due to alkaline pH and irritation potential.
