Waterproof Underwater Diving Phone Case Cover For Google Pixel
Skip until Google discloses waterproof treatment chemicals used.
Waterproof phone cases typically use water-repellent coating coatings that may contain PFAS. Google provides no disclosure of materials or treatment chemicals, leaving PFAS risk unresolved.

The full breakdown
What it's made of and why it matters
This case is a rigid plastic shell with an unspecified waterproof coating applied to seal seams and surfaces. The plastic substrate itself (likely polycarbonate or TPU blend) poses minimal chemical leaching risk under normal phone-case use. However, the waterproofing treatment is the unknown variable: it could use PFAS-based durable water repellents, silicone polymers, or other sealants, each with different safety profiles that Google has not publicly disclosed.
The brand's record and disclosure
Google has not published detailed material declarations or chemical safety data sheets for this accessory line. The company has made general commitments to reduce PFAS use across products but has not specifically addressed waterproof phone cases. This silence is notable because waterproofing treatments are a known source of PFAS in consumer products, and competitor transparency on this point is improving.
How it compares in its category
Waterproof phone cases from major brands (Apple, OtterBox) similarly lack full chemical disclosure, making this product typical rather than exceptional. However, some third-party case makers have begun specifying non-PFAS waterproofing. Compared to those, Google's silence puts it behind the transparency curve, even if the actual hazard level may be identical.
If you buy it
Inspect seals and gaskets monthly for cracking or discoloration, which signals coating degradation and reduced waterproof integrity. Avoid prolonged heat exposure (direct sun, hot car interiors) as this can accelerate plastic embrittlement and coating breakdown. Replace the case if you notice peeling, cloudiness, or water ingress, as these indicate the protective barrier is failing. Store in a cool, dry place when not in use to extend seal lifespan.
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.”
Undisclosed waterproof coating chemicals
Waterproof treatments on phone cases frequently rely on PFAS or other persistent polymers. Google's refusal to specify the chemistry leaves the hazard profile unconfirmed but statistically likely given industry norms.
Plastic degradation and microplastic shedding
Repeated thermal stress, UV exposure, and salt water (if used in ocean diving) can degrade the plastic shell and cause small particles to shed into aquatic environments or food contact if case is reused for storage.
Gasket and seal material toxicity
Rubber and silicone gaskets used in waterproof seals are generally well-tolerated, but Google does not disclose the specific elastomer formulation or whether it contains phthalates, antimony, or other additives.
Off-gassing from plastic and adhesives
New plastic cases may release volatile organic compounds (VOCs) during the first days of use. This is typically mild and temporary, but no data from Google on the solvents or adhesives used to bond the waterproof coating.
Bacterial or mold growth in sealed pocket
If moisture becomes trapped inside the sealed case due to improper closure or temperature cycling, anaerobic conditions can promote microbial growth. Regular drying and inspecting seals is essential.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 40% 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.
