Piroctone Olamine-CAS 68890-66-4
Piroctone Olamine (OCT) is a high-efficiency and mild new-generation anti-dandruff scalp care cosmetic raw material.
Different from traditional zinc pyrithione (ZPT) anti-dandruff ingredients with strong irritation and dryness, it inhibits the growth of Malassezia, the core cause of dandruff, through metal ion chelation mechanism, fundamentally solving scalp itching, flaking and oily dandruff problems.
With ultra-mild properties, it does not damage scalp barrier or cause dry and frizzy hair after use.
It is the only globally approved anti-dandruff active ingredient applicable to both rinse-off and leave-on hair care products.
It features wide pH adaptability, high-temperature processing stability and excellent formula compatibility, and also has mild broad-spectrum antibacterial and preservative auxiliary effects.
It is a mainstream safe and efficient functional raw material for high-end mild anti-dandruff and healthy scalp care formulas.
