Wave Spas Waterproof Phone Cover
Skip. Waterproof coating composition not disclosed.
Waterproof phone cases typically use water-repellent coating (water-repellent coating) coatings, often Teflon-family coating-based, but Wave Spas provides no material or coating details. Brand silence on composition raises concern.

The full breakdown
What it's made of and why it matters
Wave Spas phone covers combine plastic or elastomer (likely TPU or silicone) with an unspecified waterproof coating. The coating composition is critical because waterproofing often relies on fluorinated compounds (PFAS or alternatives), which manufacturer silence does not rule out. Without disclosure of resin type, plasticizers, or coating chemistry, residual chemical leaching onto skin or into moisture trapped against the phone cannot be assessed.
The brand's record and disclosure
Waterproof Case Co. has not published material safety data sheets, ingredient disclosures, or PFAS policy statements in publicly available sources. No third-party certifications (such as Bluesign or similar) appear associated with this product line. The brand's silence on coating formulation and chemical composition is a significant transparency gap in a product category where waterproofing chemistry directly affects consumer safety.
How it compares in its category
Waterproof phone cases vary widely; some use disclosed PU coatings or silicone without fluorinated additives, while others do not disclose. Wave Spas offers no competitive advantage in material transparency. Competing brands (e.g., OtterBox, Lifeproof) similarly rarely disclose full coating chemistry, making this product typical rather than exceptional in lack of openness.
If you buy it
Avoid prolonged skin contact with the exterior coating; wash hands after extended use, especially in warm conditions that may increase leaching. Do not expose to heat above 60-70°C or leave sealed against skin for hours. Replace every 12-18 months or if coating shows cracks, peeling, or discoloration. Store dry and away from direct sunlight to slow degradation.
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.”
Waterproof coating leachables (undisclosed fluorinated or non-fluorinated compounds)
Manufacturer does not disclose coating chemistry. Waterproof elastomer or plastic coatings can leach unreacted oligomers, plasticizers, or residual monomers onto skin or into trapped moisture, particularly under warm or humid conditions.
Phthalate plasticizers in elastomer or adhesive layers
If the elastomer component (TPU or similar) or the adhesive bonding coating to substrate uses phthalate-based plasticizers, skin contact may result in dermal absorption. No third-party testing or material certification rules this out.
Microplastics from coating or elastomer degradation
Over months of use, the exterior coating may degrade into particles; if the product deteriorates against skin or is chewed (e.g., by children), ingestion of microplastics is plausible. Replacement timeline not specified by brand.
Bacterial or mold growth in trapped moisture
Waterproof phone cases create high-moisture microclimates if not dried after water exposure. Biofilm and microbial growth are well-documented in tight-fitting waterproof enclosures; interior surface hygiene depends entirely on user maintenance.
Heavy metals or dyes in colored elastomer or coatings
No recalls or testing results for Wave Spas products specifically document heavy metal contamination. Standard polymer safety regulations in most markets limit but do not eliminate this risk; verification by independent lab testing would be required.
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.
