Piroctone Olamine

Piroctone Olamine is the ethanolamine salt of piroctone (1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2(1H)-pyridinone), developed as a more stable and cosmetically elegant alternative to zinc pyrithione. Its cationic nature allows it to substantiate onto hair and scalp, providing prolonged antimicrobial activity against Malassezia fungi and other microorganisms responsible for dandruff and seborrheic dermatitis. Formulators favor it for its excellent efficacy at low concentrations (typically 0.5-1.0%), superior solubility compared to ZPT, lack of discoloration issues, and compatibility with a wider range of surfactant systems, making it particularly suitable for clear shampoo formulations and leave-on scalp treatments.
