NIKWAX Nubuck & Suede Waterproofing Spray
A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.
Nikwax says it has never used PFAS in any of its products. We record that as an unverified brand claim. Its record describes a water-repellent or grease-resistant treatment of unstated chemistry, which is still counted.
Brand says: “Nikwax says it has never used PFAS in any of its products.”

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Volatile organic compounds (VOCs) / inhalation risk during application
Spray application releases airborne solvent and propellant; specific VOC profile not disclosed. Risk is highest during application in enclosed spaces. No acute toxicity data for this formulation is publicly available.
Skin and eye irritation from direct contact
Typical fabric treatment sprays carry irritant warning labels. Nikwax product labels advise avoiding contact with skin and eyes, consistent with category risk; specific irritant identity not disclosed.
Incomplete disclosure of active and inert ingredients
Nikwax does not publish detailed safety data sheets or ingredient lists for consumer spray products. This limits ability to identify specific sensitizers, solvents, or fragrance allergens that may be present.
Propellant identity and environmental/health profile
Spray cans use a propellant system not specified in publicly available product information. Propellant choice (hydrocarbons vs. compressed air) affects both inhalation risk and environmental impact; verification not possible without manufacturer disclosure.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Residual film toxicity on treated fabric
No reports of dermatitis or adverse effects from wearing nubuck/suede treated with this product after full drying. Silicone-based films are generally inert once cured, but full ingredient disclosure would be needed for definitive assessment.
The full breakdown
What it's made of and why it matters
Nikwax Nubuck & Suede Waterproofing is a silicone-based treatment spray; the exact chemical formulation is not publicly disclosed. Silicone waterproofing agents are volatile compounds that evaporate during application and cure to a water-repellent film on fabric fibers. Without ingredient-level transparency, independent assessment of solvent type, propellant choice, and residual chemical risk is not possible from available sources.
The brand's record and disclosure
Nikwax states its products are PFAS-free, but this claim has not been independently verified through third-party testing disclosed in public records or published safety data sheets. The brand does not routinely publish full ingredient lists or safety certifications (e.g., bluesign, Oeko-Tex) for its spray products. No recalls or regulatory actions specific to this product are on record.
How it compares in its category
Fabric waterproofing sprays vary widely in chemistry; most rely on silicone, wax, or fluorocarbon treatments. Nikwax positions itself as a PFAS-alternative brand, which differentiates it from legacy products still in circulation. However, the lack of published testing or certification limits ability to compare its actual hazard profile to better-disclosed competitors in the category.
If you buy it
Apply in a well-ventilated space or outdoors to avoid inhalation of volatile compounds during spraying. Do not apply to skin, eyes, or breathing-zone areas. Allow treated garments to dry fully (typically 24 hours) before contact with skin. Reapply periodically as water-repellency diminishes; frequency depends on wear and weather. Do not heat-set the treatment; air-dry only.
