New Zealand has banned the use of a group of chemicals that do not break down and are believed to have a negative impact on human health.

The Environmental Protection Authority said today, Tuesday, that the use of perfluoroalkyl and polyfluoroalkyl substances in cosmetic products will be banned starting from December 31, 2026.

New Zealand is among the first countries in the world to ban these substances, which are often referred to as "forever chemicals."

These substances are sometimes used in products such as nail polish, shaving cream, foundation, and mascara. They are added to soften the skin or make cosmetic products more durable and water-resistant.

Sean Brisco, Director of the Hazard Reassessment Division at the Authority, said international research indicates that perfluoroalkyl and polyfluoroalkyl substances have been found in a small number of products.

He added, "But we adopt a cautious approach towards the potential risks of these substances."

He explained: "We know that these substances do not break down easily, can accumulate inside our bodies, and some can be toxic at high levels."
