Forever chemicals are sometimes used in products such as nail polish (German)

New Zealand has banned the use of a range of break-down chemicals believed to have a negative impact on human health.

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

New Zealand is one of the first countries in the world to ban these substances, often called "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.

Director of the Authority's Substances Hazard Re-evaluation Division, Shawn Briso, said that 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 toward the potential risks of these materials."

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