Why was zinc pyrithione banned?

Zinc pyrithione, also called pyrithione zinc or ZPT, is a “coordination complex” of zinc and pyrithione. It’s an ingredient in skincare and hair products because of its antibacterial, antimicrobial, and antifungal properties.

Risks and Side Effects

The use of pyrithione zinc in over-the-counter products, such as shampoos, creams, and soaps, has received FDA approval. Its topical application in recommended dosages is deemed safe.

It may burn or sting if it gets in the eyes, mouth, or nose. Possible adverse effects may involve a sensation of burning or redness, and exceptionally, the development of blisters.

If you experience any adverse effects, stop using the product immediately.

The Ban on the Cosmetic Anti-dandruff Agent Zinc Pyrithione (ZPT)

Due to concerns over its safety, the use of ZPT in cosmetics has been banned in some countries.

The ban on ZPT is mainly due to concerns about its potential toxicity. Studies have shown that the use of ZPT can lead to skin irritation, photosensitivity, and other allergic reactions. Additionally, there are worries about the potential harm it could cause to the environment, specifically its impact on water-based ecosystems.

In 2012, the European Commission banned the use of ZPT in cosmetic products in concentrations higher than 1%. In 2016, the European Union instituted a prohibition on the application of ZPT in hair color products. Other countries, such as Japan and Canada, have also restricted or banned the use of ZPT in cosmetics.

Overall, the ban on ZPT in cosmetics highlights the increasing emphasis on consumer safety and environmental concerns in the cosmetics industry.
