Also known as
Octopirox 1-Hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)-2(1H)-pyridinone ethanolamine salt Piroctone Ethanolamine OPT
Compatibility
Works well with:
Zinc Pyrithione Salicylic Acid Glycerin Panthenol Niacinamide Cetrimonium Chloride
Use caution with:
Strong oxidizing agents High concentrations of iron or heavy metal ions
Piroctone Olamine can form complexes with metal ions such as iron and copper, which may reduce its efficacy; chelating agents like EDTA can help mitigate this. It is compatible with most common cosmetic surfactants and conditioning agents at typical use levels. It can be combined with Zinc Pyrithione for enhanced anti-dandruff efficacy in shampoo formulations.
Formulation notes
Piroctone Olamine is a broad-spectrum antimicrobial and antifungal agent primarily used as an anti-dandruff active, effective against Malassezia species implicated in dandruff and seborrheic dermatitis. It also functions as a secondary preservative in leave-on and rinse-off formulations. It is generally considered well-tolerated and is a popular alternative to Zinc Pyrithione for formulators seeking a cleaner or more cosmetically elegant profile.
