Why choose shampoo piroctone olamine?

Piroctone Olamine is a highly effective yet gentle anti-dandruff and anti-itch agent. As a manufacturer, Kintainutri® supplies 99% purity Piroctone Olamine powder to major brands. It addresses the root causes of dandruff and itching by inhibiting the activity of Malassezia fungi on the scalp, while significantly reducing the irritation often associated with traditional anti-dandruff agents.

It effectively regulates sebum secretion, making it ideal for oily scalps, and provides Antioxidant benefits that help scavenge free radicals and soothe scalp inflammation. This synergistic combination of anti-inflammatory and oil-control properties fosters a healthier, more stable micro-environment for hair growth.

It alleviates scalp inflammation caused by seborrheic dermatitis at the source by inhibiting Malassezia proliferation and reducing the production of free fatty acids; additionally, its antioxidant properties, which scavenge superoxide and hydroxyl radicals, help protect hair follicle health.

After 28 days of using a shampoo containing 0.1% Piroctone Olamine, test subjects showed a significant reduction in hair loss (dropping from 28.5 to 12 strands, a 57.89% decrease) and a 2.76% increase in local hair density. Concurrently, scalp sebum secretion dropped significantly (by 27.32%), and visual dandruff scores improved markedly (by 9.88%). Shampoos containing Piroctone Olamine offer significant benefits for hair health.

As a raw material supplier, we provide high-purity (≥99%) product suitable for developing multi-functional shampoos and scalp care formulations that address dandruff, oil control, and hair loss prevention.

Although Zinc Pyrithione (ZPT) has long been widely used to treat dandruff, scalp itching, and seborrheic dermatitis due to its potent antifungal and antibacterial properties, it has been completely banned as a cosmetic ingredient in the EU and other regions due to potential environmental toxicity—specifically, its tendency to bioaccumulate and harm aquatic life. This major shift in regulatory oversight is driving global shampoo formulators to accelerate the search for greener, milder, and compliant next-generation anti-dandruff alternatives.

Piroctone olamine powder is not only toxicologically safe and extremely gentle on the scalp but also precisely targets and inhibits Malassezia, the fungus responsible for dandruff, at the source. Beyond its anti-dandruff capabilities, it reduces hair loss, increases the proportion of hair in the growth phase, boosts hair shaft diameter, and controls oil—unique advantages that ZPT cannot match. Furthermore, its excellent water solubility perfectly resolves the formulation challenge that prevented ZPT from being used in premium transparent shampoos.

Backed by technical data from Clariant, Piroctone olamine (Octopirox®) is clinically proven to significantly reduce dandruff and alleviate itching within days at a concentration of just 0.5%. Compared to traditional ZPT, its superior solubility enables the development of modern product formats such as transparent shampoos, dry shampoo powders, and leave-on serums, while also offering broad-spectrum preservative, anti-acne, and deodorizing properties. 

With a strong safety profile, being neither sensitizing nor mutagenic, it is an ideal compliant choice in the trend of replacing ZPT. Its low usage levels (0.05%–1.0%) and high compatibility facilitate the rapid market launch of products with differentiated benefits.

In recent years, Piroctone olamine has increasingly replaced ZPT, becoming the core choice for anti-dandruff formulations used by leading international brands such as L'Oréal and Kérastase. L'Oréal Group’s La Roche-Posay Kerium line and Vichy Dercos Sensitive Scalp shampoo rely heavily on this ingredient to meet dermatologists' rigorous standards for gentleness and safety. 

Meanwhile, the luxury salon brand Kérastase leveraged the ingredient's excellent solubility to create a transparent anti-dandruff gel, breaking the mold of traditional opaque anti-dandruff shampoos and thereby demonstrating the comprehensive advantages of Piroctone Olamine in terms of efficacy, formulation flexibility, and safety.
