Body Glove Tidal Waterproof Case for Galaxy S25 Ultra
Unknown waterproofing treatment. No PFAS disclosure from Body Glove or Samsung.
Body Glove waterproof phone cases typically use TPU with a durable water-resistant coating, but neither brand discloses whether PFAS water-repellent coating (water-repellent coating) treatments were used. Contact the manufacturer for specifics.

No PFAS disclosure

PFAS
The waterproof treatment applied to this TPU case is not disclosed by either Body Glove or Samsung. Industry standard for phone case waterproofing often involves PFAS compounds; the 40/100 PFAS safety grade reflects this opacity.
Source: ATSDR ↗TPU degradation and leaching
TPU itself is stable, but when exposed to sustained heat, UV light, or physical stress, it can degrade and release oligomers. This is unlikely during normal phone use but possible if the case is left in hot vehicles or direct sun for weeks at a time.
Microplastic shedding from case wear
TPU cases are durable but can shed fine particles when rubbed, scratched, or bent repeatedly. This contributes to microplastic exposure if particles contact food or skin, though the magnitude is small relative to other sources.
Seal integrity failure and moisture ingress
If the waterproof seal fails (cracks, peeling, or delamination), water and humidity may be trapped against the phone, creating conditions for bacterial growth or corrosion rather than protecting the device. This is a functional safety concern rather than a direct chemical hazard.
What’s reassuring
Allergen sensitivity to TPU or adhesives
No documented allergic reactions to Body Glove S25 Ultra cases exist on public record. TPU is generally considered hypoallergenic, though individual sensitivity to synthetic polymers or adhesives used in assembly is theoretically possible.
The full breakdown
What it's made of and why it matters
This case is thermoplastic polyurethane (TPU), a flexible synthetic polymer that does not inherently leach BPA, phthalates, or heavy metals under normal handling. TPU is chemically stable at room temperature and during typical phone use. The waterproofing treatment applied to the TPU is the unknown variable: Body Glove and Samsung have disclosed nothing about whether this involves PFAS-based water repellents, which are common in the industry but undisclosed here.
The brand's record and disclosure
Body Glove (a subsidiary of Sekisui) has no public record of PFAS transparency statements or restrictions on chemical inputs in phone accessories. Samsung has made limited commitments on PFAS in consumer products and does not disclose chemical treatments for third-party accessory lines. Neither company has published test results for leaching or off-gassing from this specific case formulation. No recalls or safety incidents specific to this product model are publicly documented.
How it compares in its category
Phone cases made from TPU are among the safer options chemically compared to vinyl or phthalate-laden plastics, but waterproof cases universally carry the risk of undisclosed PFAS coatings. Competitors like OtterBox and Spigen similarly lack transparent waterproofing ingredient lists. Cases with published PFAS-free certifications are rare in the smartphone market and typically command a premium or are unavailable for flagship models like the S25 Ultra.
If you buy it
Inspect the case monthly for cracks, peeling, or discoloration in the waterproof layer, as degradation can accelerate leaching if PFAS or other coatings are present. Avoid prolonged contact with skin (especially if you have sensitivity) and do not leave the case in direct sunlight for extended periods, which can degrade TPU. Wash your hands after handling if you notice any off-gassing smell. Replace the case if seals degrade or if you develop unexplained skin reactions around device contact areas.
