Description
Piroctone Olamine Product Overview
Piroctone olamine is the ethanolamine salt of piroctone, a hydroxypyridone compound. It is a white to slightly yellow powder that dissolves sparingly in water but well in surfactant solutions, ethanol and glycols, which makes it easy to incorporate into shampoos.
Its main use is in anti-dandruff shampoos and scalp care, where it controls the Malassezia yeasts associated with dandruff. Since zinc pyrithione was banned in EU cosmetics, it has become one of the leading anti-dandruff actives, often combined with Climbazole. It also works as a preservative booster in leave-on and rinse-off products.
In the EU, it is permitted in rinse-off products at up to 1% and in other products at lower levels. It is typically used in shampoos based on Sodium Lauryl Ether Sulfate and is compatible with most cosmetic ingredients, although strong light and certain metal ions can cause discoloration.
