Banned ‘forever chemicals’ still present in ski wax rooms with unresolved health dangers
Ski waxes containing PFAS were banned, but the chemicals persist. For decades, manufacturers added these synthetic compounds to skis and snowboards to reduce friction and deliver a critical speed advantage in competitive racing. Then the health warnings came, and the sporting bodies acted. But the “forever chemicals” have not gone away.
The ban on fluorinated ski waxes
The International Ski and Snowboard Federation (FIS) and the International Biathlon Union (IBU) both banned fluorinated waxes in all sanctioned competitions beginning with the 2023-24 season. The IBU had already prohibited C8 fluorocarbons earlier. In the United States, the US Ski & Snowboard and the Canadian Ski Association joined those bans. Local venues and municipalities also moved early: the Craftsbury Outdoor Center in Vermont and Park City, Utah, restricted the use of these waxes. Across the Atlantic, France implemented a ban on PFAS in ski wax in January 2026 as part of a wider restriction covering cosmetics and clothing.
The bans, together with evolving regulations, have largely phased fluorinated waxes out of production. But the regulatory landscape is still shifting. The European Chemicals Agency (ECHA) is progressing a proposed near-total ban on PFAS under the REACH regulation, covering more than 10,000 substances. ECHA’s committees have supported the group‑based restriction as the most appropriate measure. In the United Kingdom, the government published its first PFAS Plan in February 2026, outlining a three‑pillar strategy to understand sources, tackle pathways and reduce ongoing exposure. The plan includes expanded environmental monitoring, research into ecosystem impacts, and a commitment to reform UK REACH to align with EU regulations by December 2028. The UK is also expected to consult on a statutory PFAS limit for drinking water in 2026.
Why PFAS are so difficult to remove
The reason these chemicals linger long after a ban lies in their molecular structure. PFAS — per‑ and polyfluoroalkyl substances — are built around carbon‑fluorine bonds, among the strongest in chemistry. First developed in the 1930s and commercialised widely from the 1950s, they were added to ski wax from the mid‑1980s onward. Once released, they do not degrade easily in the environment or inside the human body. That durability gives them their nickname: forever chemicals.
New research by scientists at the University of Alaska Southeast and their colleagues illustrates just how stubborn they are. The study examined dust from ski‑waxing work areas after the fluoro bans were implemented and the rooms had been cleaned. PFAS concentrations had fallen substantially — but they had not been fully eliminated. Even tiny amounts of PFAS can pose risks to human health, the researchers note. The chemicals persist in indoor dust, in the soils around ski resorts, and in the bodies of those who work with them.
Scientific research has linked PFAS exposure to a range of adverse health effects, including increased risks of thyroid, liver and cardiometabolic diseases, certain cancers, immune system suppression, fertility issues and developmental problems in unborn children. Studies have found high concentrations of PFAS in the blood of professional ski‑wax technicians — levels comparable to or exceeding those seen in fluorochemical plant workers. Even recreational skiers who wax their own skis appear to be exposed; a pilot study found that individuals who waxed more skis tended to have higher levels of PFAS in their blood and also higher total cholesterol and “bad” LDL cholesterol, both risk factors for cardiovascular disease.
The problem is compounded by the way PFAS travel. When skis are waxed, tiny particles and chemicals can become airborne. This means the risk is not confined to professional waxers. The researchers’ earlier work indicated that a broad range of skiers might be exposed. And because the chemicals do not break down, every gram of PFAS that has ever entered a snow‑sports environment remains there — or moves through soil, water and air to other locations. Even where skiing does not occur, small detections of PFAS are found owing to their widespread presence in the environment.
Adding to the complexity, some skiers still possess older fluorinated waxes and may be inclined to use them from time to time. Wax manufacturers are now searching for alternative chemistries that can replicate the glide of fluoros, especially in warm, wet or dirty snow. But the exact composition of these new waxes is typically proprietary, shielded from disclosure by intellectual property and confidential business information laws. That means their long‑term safety and environmental impact remain open questions.
What skiers can do to stay safe
Despite the bans, people working in wax rooms and those in the vicinity still face ongoing PFAS exposure risks. There are steps skiers and snowboarders can take to reduce lingering exposure. The advice from researchers is straightforward: stop using any remaining fluorinated wax. Always wax in a well‑ventilated space or outdoors. Wear personal protective equipment — an N95 mask or a respirator with organic cartridges — when waxing. Do not eat or drink in the areas where you wax or tune your skis to avoid ingesting wax dust. Wash your hands and change your clothes after leaving the waxing space. Finally, clean the wax area with a vacuum equipped with a HEPA filter and a damp cloth to prevent the accumulation of wax‑related dust.
