Outdoor Products SmartPhone Watertight Phone Case
Unknown coating composition. Waterproof cases often use PFAS-based water-repellent coating treatments.
Dexcraft has not disclosed materials or waterproofing method for this case. Waterproof phone cases commonly rely on Teflon-family coating coatings, which typically contain PFAS.

The full breakdown
What it's made of and why it matters
This case is likely constructed from TPE (thermoplastic elastomer) or silicone with an applied waterproof coating. TPE and silicone themselves are generally stable polymers with low leaching risk under normal phone-use temperatures. However, the waterproof/water-repellent (water-repellent coating) treatment applied to the surface is the critical unknown: most commercial waterproof phone cases use PFAS-based Teflon-family coating or water-repellent chemistries to achieve durability, which can degrade and release compounds over time, especially if the case is flexed repeatedly or exposed to heat.
The brand's record and disclosure
Dexcraft has no established public record of PFAS disclosure, toxicology testing, or independent certifications for this product line. The brand's silence on waterproof coating composition is typical of smaller outdoor-product manufacturers but leaves consumers unable to confirm whether PFAS or safer alternatives were used. No recalls or safety controversies specific to this brand are documented in public databases, but lack of transparency is itself a red flag for a product where coating chemistry directly affects safety.
How it compares in its category
Waterproof phone cases occupy a difficult safety middle ground. Premium brands (e.g., LifeProof, OtterBox) often disclose materials but rarely commit to PFAS-free formulations; budget cases like this one typically do not disclose at all. Cases made from untreated silicone or TPE without added water-repellent coating coatings exist but are less water-resistant. This product's lack of transparency puts it below brands with published PFAS commitments but not fundamentally worse than most mainstream alternatives in this price tier.
If you buy it
Keep the case away from prolonged heat (e.g., avoid leaving it in direct sunlight for hours or near hot surfaces) to reduce risk of coating breakdown and leaching. Replace the case every 1-2 years or if you notice visible cracking, peeling, or discoloration of the waterproof layer, as these are signs the coating is degrading. Do not use the case as a food-contact surface or allow it to contact drinking water for extended periods. Consider using it primarily for protection rather than assuming the waterproof seal is indefinite; test it periodically with a small moisture check inside the case.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS-based waterproof coating (off-gassing and leaching)
Waterproof phone cases of this type almost universally rely on Teflon-family coating water-repellent coating treatments. Dexcraft's silence on this and the 40/100 PFAS safety grade you've assigned indicate unknown, probably PFAS-containing coating; these can leach into skin contact and off-gas, especially if flexed or heated.
TPE/silicone leachables under heat or contact with oils
While TPE and silicone are generally inert, additives (plasticizers, slip agents, UV stabilizers) in lower-cost formulations can leach when the case is exposed to heat, phone body oils, or alcohol-based cleaning agents. No specific test data for Dexcraft's formulation is publicly available.
Coating degradation and microparticle shedding
As the waterproof coating cracks or peels over time (common in flexible cases subject to repeated bending), small particles of the coating can shed. The composition of these particles is unknown, but if PFAS-based, inhalation or skin contact becomes a minor but real risk, especially for users who handle the case frequently.
Bacterial growth in case seams and crevices if moisture is trapped
Waterproof cases by design trap moisture if water enters. Poor maintenance or a compromised seal can allow bacterial or mold growth inside the case, which then contacts the phone and user's skin. This is a maintenance and design issue rather than a material toxicity issue but should be monitored.
Heavy metals in colorants or UV stabilizers
No specific data on Dexcraft's dye or stabilizer choices is publicly available. Budget TPE cases occasionally use colorants with trace heavy metals, but this is not documented for this brand and would only pose risk on skin contact over long periods.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
