Mechanism of Action
Piroctone Olamine is a broad‑spectrum antimicrobial and antifungal agent. Its primary mechanism is the chelation of essential metal ions (e.g., iron), thereby inhibiting fungal metabolism and growth. It is particularly effective against Malassezia species, the primary cause of dandruff.
Additional benefits include:
Sebum regulation: Reduces excessive sebum production on the scalp and skin
Anti‑inflammatory activity: Alleviates itching and irritation
Deodorant effect: Suppresses odor‑causing bacteria
Applications
Piroctone Olamine is widely used in personal care products, both rinse‑off and leave‑on formulations:
Hair care: Anti‑dandruff shampoos, scalp lotions, tonics
Skin care: Acne treatment products (due to its antimicrobial and sebum‑controlling properties)
Deodorants: Spray or roll‑on deodorants, also for pet care products
Typical Use Concentrations
Rinse‑off products (shampoos, body washes): ≤ 1.0 %
Leave‑on products (scalp serums, creams): ≤ 0.5 %
Deodorant sprays: 0.2–0.5 %
Storage
Store in a tightly closed container, protected from light, heat, and moisture. Refrigeration (0–10 °C) is recommended for long‑term stability.
