Piroctone Olamine ●
TL;DR. This ingredient is primarily an anti-dandruff and scalp-care active with antimicrobial activity, especially in rinse-off hair products. It can also support preservation in formulas where scalp fungal control is part of the product design.
What does Piroctone Olamine do in a cosmetic formula?
This ingredient is primarily an anti-dandruff and scalp-care active with antimicrobial activity, especially in rinse-off hair products. It can also support preservation in formulas where scalp fungal control is part of the product design.
Is Piroctone Olamine clean?
From a clean-beauty perspective, this ingredient is a synthetic, regulated active rather than a broadly accepted natural-format material. It is generally well tolerated at permitted levels, but concentration limits and its antimicrobial role create some clean-standard friction.
Is Piroctone Olamine sustainable?
This material is synthetically produced and is not a renewable plant or mineral ingredient. Its low use levels reduce formula load, but its aquatic-effects profile and limited natural-standard acceptance make it a moderate sustainability fit rather than a strong one.
Is Piroctone Olamine COSMOS-approved?
It is not generally permitted in COSMOS-natural or COSMOS-organic products, because it does not fit the standard’s allowed natural-origin and preservative frameworks. Its Green Chemistry alignment is limited by synthetic sourcing and weaker biodegradability credentials, despite effective performance at low concentrations.
How does Piroctone Olamine work chemically?
The molecule is an ethanolamine salt of a substituted hydroxamic acid with amphiphilic character, and it acts partly by binding metal ions that fungi need for normal metabolism. Typical use is about 0.1 to 1% in anti-dandruff shampoos and lower in leave-on formats, with formulation support often needed for solubility and even distribution.
