Rex Purple Liquid Grip Wax
Likely lower concern, but brand discloses nothing about PFAS.
This ski wax product has no known PFAS-specific formulation or public PFAS claims. Wax products typically pose lower PFAS risk than water-repellent textiles, though brand transparency is absent.

What Rex Purple Liquid Grip Wax is made of, ingredients and materials
Rex Purple is a hydrocarbon-based ski wax designed to improve board grip and glide on snow. The formulation is typically a blend of paraffin and/or microcrystalline wax with synthetic resins and additives for temperature-specific performance. As a topical wax applied directly to ski/board bases and feet, systemic absorption risk is low, though skin contact and inhalation during application warrant basic precautions.
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.
Hydrocarbon solvent vapors (volatile organic compounds)
Ski waxes release low levels of aliphatic hydrocarbons when applied, particularly in warm or indoor conditions. Exposure is typically brief and outdoor-oriented for this product; chronic risk is minimal for recreational users applying sparingly, but indoor application without ventilation may produce noticeable odor and respiratory irritation in sensitive individuals.
PFAS
Conventional ski waxes historically contained fluorocarbons (PFOS/PFOA) for performance; Rex does not publicly confirm PFAS-free status. The brand's silence is a transparency shortfall. Available evidence suggests many modern conventional waxes have reduced PFAS loads, but independent testing of Rex Purple is not publicly available.
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Skin irritation or contact dermatitis
No published adverse events for Rex Purple specifically. Standard wax products occasionally trigger mild irritation in users with sensitive skin; risk is low with glove use and hand washing post-application.
Ingestion risk (incidental)
Wax applied to ski/board bases contacts snow and can transfer trace amounts to lips or mouth during outdoor use. Paraffin wax itself is non-toxic and used in food-grade applications; systemic toxicity from incidental ingestion is not a documented concern for this product class.
Heavy metals
No recalls or test results for lead, cadmium, or other metals in Rex wax products. Wax-based products do not typically bioaccumulate metals in the way ceramics or cosmetics can; risk is considered low for this category.

The brand's record and disclosure
Rex is a well-established Scandinavian ski wax manufacturer with decades of market presence; no major product safety recalls or contamination incidents are on public record for this line. The brand does not publicly disclose PFAS content, certification against PFAS, or detailed ingredient lists, which is a transparency gap shared by most conventional wax competitors. Absence of disclosure is not evidence of contamination, but limits independent verification.
How it compares in its category
Rex waxes are mainstream performance products and compete with other petroleum-derived ski waxes (Swix, Toko, Marucha); they occupy the standard risk profile for the category rather than positioning as low-chemical or eco-alternative. Most competing brands likewise provide minimal PFAS transparency. Fluorocarbon-free wax alternatives (marketed as PFOS/PFOA-free) exist but are not mainstream and carry their own trade-offs in performance.
If you buy it
Apply in a well-ventilated space or outdoors to minimize inhalation of wax fumes and dust. Use gloves to avoid prolonged skin contact and wash hands after application. Store in a cool, dry place away from direct heat (wax will soften or melt above 60-70 degrees Celsius). Replace when visibly worn, damaged, or after 50-100 days of regular use depending on conditions; old wax provides diminishing grip and glide performance.
