The full breakdown
What it's made of and why it matters
Google's waterproof case is constructed from TPU (thermoplastic polyurethane), a flexible synthetic rubber polymer commonly used in phone protection. The case includes an undisclosed waterproof coating or treatment that enables water resistance. TPU itself is generally considered non-toxic in normal use, but the unidentified coating is the transparency gap: waterproofing treatments often rely on fluorochemical compounds (including PFAS-class substances) to achieve water and oil repellency, and Google has not publicly specified what coating is applied.
The brand's record and disclosure
Google has not published material safety data sheets, chemical disclosures, or certifications for this accessory. The company has made no public statements about PFAS use in phone cases or waterproofing treatments. This silence contrasts with major outdoor gear and apparel brands that have begun phasing out long-chain PFAS; Google's lack of disclosure on this product makes independent verification of safer alternatives impossible. No recalls or safety incidents have been formally reported for this specific case.
How it compares in its category
Waterproof phone cases across brands typically rely on TPU or silicone bodies with fluorochemical or paraffin-based water-repellent coatings. Cases marketed with explicit fluorine-free or PFAS-free waterproofing (rare) are available from niche manufacturers but command price premiums. Google's case occupies the mainstream segment where coating composition is routinely undisclosed industry-wide. Comparable OEM cases (Apple, Samsung) similarly do not publish coating chemistry, making this product typical rather than exceptional in opacity.
If you buy it
Use the case as designed: protect the phone during water exposure, then remove and allow to air dry. Do not expose to sustained heat (avoid saunas, dishwashers, or prolonged direct sunlight). Inspect the coating annually for visible cracks, peeling, or degradation; if integrity is compromised, the waterproof function is lost and replacement is warranted. Wash the case with mild soap and water if soiled; avoid solvents or harsh scrubbing that can degrade the coating.
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 waterproofing coating chemistry
Waterproof TPU cases commonly use fluorochemical treatments; Google has not disclosed whether PFAS, short-chain fluorochemicals, or non-fluorine alternatives are used in this specific product, precluding informed assessment of coating safety.
TPU polymer degradation and leaching
TPU itself is not known to leach harmful chemicals under normal phone case use conditions. No published incidents of toxicant release from TPU waterproof cases have been recorded.
Coating integrity loss over time
Waterproof coatings on TPU degrade with age, heat, UV exposure, and physical wear. Once the coating fails, water ingress can damage the phone and the case loses its protective function; replacement is then necessary.
Allergen contact (rubber/TPU sensitivity)
TPU is not a known latex allergen, but some individuals may experience localized skin irritation from prolonged contact with synthetic rubbers; this is product-agnostic and uncommon.
Microplastic shedding from worn coating
As waterproof coatings flake or degrade, they may shed microparticles during handling or care. The extent and composition of shed particles are not characterized for this product.
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.
