Sodium Cocamidopropyl Pg-Dimonium Chloride Phosphate

What is Sodium Cocamidopropyl Pg-Dimonium Chloride Phosphate?

Sodium Cocamidopropyl PG-Dimonium Chloride Phosphate is a synthetic quaternary ammonium compound derived from coconut fatty acids, propylene glycol, and phosphate groups, forming a cationic phospholipid structure. Commonly found in rinse-off hair care products like shampoos and conditioners. It functions through its positive charge, which binds to negatively charged hair shafts, smoothing cuticles to reduce tangles and static. As a mild surfactant, it lowers surface tension to lift dirt and oils into micelles for easy rinsing, preserving hair's natural moisture balance. Its foam-boosting properties create rich, stable lather, enhancing the washing sensation without compromising gentleness on scalp and strands.
