Zinc Pyrithione in Textiles: Toxicity, Bans, and Safer Alternatives
Zinc pyrithione is a biocidal substance still widely used across industries. In March 2022, it was prohibited for use in cosmetic products in the EU, where it had been common in anti-dandruff shampoos and as a preservative.
However, the substance continues to be used in the textile industry, particularly for anti-odor treatments in garments such as sportswear.
Why Is Zinc Pyrithione Harmful?
Zinc pyrithione is a very hazardous chemical substance. It is classified in the European Union as:
■ Acutely toxic
■ Toxic to reproduction (may damage unborn children)
■ Very hazardous to aquatic environments
