Ghostek Nautical Slim Case for MagSafe for Samsung Galaxy S25 Ultra
Lower concern; rigid phone cases rarely use PFAS. No data available.
Ghostek phone cases are typically polycarbonate and TPU polymers without noted waterproofing or coatings linked to PFAS. No public PFAS disclosures or testing reported.

Why this grade
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Category baseline
other is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This case combines polycarbonate (hard plastic shell for impact resistance) and thermoplastic polyurethane (TPU, flexible bumper layer). Both are rigid, non-food-contact polymers designed for durability and shock absorption. Neither material is known to leach chemicals during normal room-temperature use. The MagSafe integration uses embedded magnets that do not generate chemical hazards at consumer exposure levels.
The brand's record and disclosure
Ghostek is a third-party accessory maker, not Samsung itself; they do not publish detailed material safety data or sustainability certifications for this product line. No recalls or safety incidents on record for Ghostek phone cases. The brand maintains minimal transparency on chemical testing or material sourcing, which is typical for accessory manufacturers but limits independent verification of manufacturing controls.
How it compares in its category
Phone cases made from polycarbonate/TPU blends are industry standard and considered low-hazard compared to fabric cases (potential flame retardant treatments) or liquid cases (risk of seal failure and internal liquid leakage). Ghostek's slim design avoids the bulk of heavier reinforced cases, reducing material volume but maintaining adequate protection for normal drops. No meaningful safety advantage or disadvantage versus comparable third-party brands at this price point.
If you buy it
Clean periodically with mild soap and water; do not expose to prolonged heat above 60 degrees Celsius (dishwashers, car dashboards in direct sun). TPU can yellow or degrade over 2-3 years of UV exposure, particularly if stored in sunlight. Replace if cracks, delamination, or button wear develops, as structural integrity drops sharply after visible damage. Keep magnets away from medical devices (pacemakers, insulin pumps).
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.”
BPA/BPS in polycarbonate
Polycarbonate does not migrate BPA during normal room-temperature contact with skin or non-oily substances. This is a non-food item with no eating or drinking contact pathway.
Phthalates in TPU
TPU formulations may contain phthalate plasticizers, but migration into skin from a phone case at ambient temperature is negligible based on material chemistry. No data available on this specific product's phthalate content or sourcing.
Volatile organic compounds (VOCs) off-gassing
New cases may emit low levels of odor from manufacturing residues or trapped solvents, particularly in the first few days. Airing the case before use or storing in a ventilated space minimizes exposure; this is temporary and not associated with long-term health risk.
Antimony in polyester (if present in dyes or coatings)
Antimony is not typically used in rigid phone case manufacturing. Polycarbonate and TPU do not require antimony-based flame retardants or catalysts in consumer-grade formulations.
Microplastics shedding
Wear and abrasion of TPU and polycarbonate can produce small plastic particles over months to years of use. The volume is minimal and exposure pathway is primarily through dust; disposal in general waste is standard practice.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 60% 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.
