What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Iron-application of fluorinated ski wax generates aerosol and vapor. Start does not disclose fluorine type or concentration, so acute fume risk and long-term accumulation cannot be quantified; common in the category but underreported.
Source, ATSDR ↗Hydrocarbon irritation and aspiration hazard
Hydrocarbon wax itself poses minimal hazard during normal use but presents low-level inhalation risk during ironing and a minor aspiration risk if ingested (unlikely in adults; keep away from children).
Thermal decomposition by-products
Overheating hydrocarbon wax above typical ironing temperature can generate volatile organic compounds and small amounts of carbon particulates; risk increases if wax is applied repeatedly at high heat or with equipment malfunction.
What’s reassuring
Skin contact irritation
No reported dermatitis or allergic reactions to Start LF10 on public record. Hydrocarbon waxes are generally skin-safe, though prolonged contact with hot wax can cause thermal burn.
Heavy metals
No testing data or recalls indicating lead, cadmium, or other heavy metals in Start ski wax formulations; hydrocarbon sources are typically well-refined.

What it's made of and why it matters
Start LF10 is a hydrocarbon-based ski wax blended with fluorinated surfactants to reduce friction on snow. Hydrocarbon waxes are non-toxic at room temperature, but the fluorinated additives (likely perfluorinated compounds) are the primary concern in this product class. Race waxes typically contain higher fluorine loading than recreational waxes to maximize speed, which increases total PFAS exposure during application and ironing. The 180g size suggests frequent use, amplifying cumulative inhalation risk during waxing sessions.
The brand's record and disclosure
Start (a Slovenian brand owned by Toko) provides no public transparency on PFAS content, fluorine sources, or safety data sheets accessible to consumers. The company has not published any statements discontinuing or certifying fluorine-free lines in race wax. No recalls or safety controversies are on public record for this product. Absence of disclosure is typical in the race ski wax market, where fluorine is still considered a performance standard.
How it compares in its category
Race ski waxes almost universally contain some form of fluorinated surfactants; Start LF10 is not an outlier in this respect. Non-fluorinated or PFAS-free race wax alternatives exist (e.g., some formulations from Swix, Dominator, or specialty brands) but are less common and often cost more. Recreational (non-race) hydrocarbon waxes are available without fluorine but sacrifice glide performance. If minimizing PFAS is a priority, switching to non-race wax or fluorine-free formulations is the most direct action.
If you buy it
Apply wax in a well-ventilated space or outdoors to limit inhalation of vapors during ironing, which is when fluorinated compounds are most likely to volatilize. Keep waxing temperature moderate (around 140-160°C / 285-320°F for hydrocarbon wax) to avoid decomposition and excess fume release. Replace the wax cake once it becomes heavily contaminated with dirt or snow particles, typically after 3-5 days of heavy skiing. Wash hands thoroughly after waxing and avoid touching face or eating before cleaning.
