Mous Phone Case for iPhone 16 Pro Max
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes thermoplastic polyurethane (TPU) shell, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Heavy metals
TPU cases often use pigments and UV stabilizers; without published material declarations, presence of lead, cadmium, or antimony cannot be ruled out, though regulatory compliance in importation suggests levels are below legal thresholds.
Source, FDA ↗Microplastics
TPU degrades very slowly at room temperature, but abrasion or surface cracking can release small particles. This is primarily a concern if fragments are ingested or shed into aquatic environments at end-of-life.
Source, EPA ↗Contact allergens or skin sensitizers from additives
TPU itself is not allergenic, but colorants, antistatic agents, or mold-release residues could trigger contact dermatitis in sensitive individuals. Washing the case before first use is a standard precaution.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Phthalates
TPU formulations can contain phthalates as processing aids, but Mous has not disclosed additives. No phthalate contamination has been reported for this product line.
Source, ATSDR ↗Volatile organic compound (VOC) off-gassing
TPU does not typically release significant VOCs at ambient temperature, unlike some silicone or PVC alternatives. No odor or air-quality complaints are on record for this product.
The full breakdown
What it's made of and why it matters
The Mous case uses thermoplastic polyurethane (TPU), a flexible elastomer that provides shock absorption without rigid brittleness. TPU does not contain bisphenol A (BPA), phthalates, or lead in its base formulation, making it chemically stable for prolonged skin contact. The material itself does not off-gas volatile organic compounds (VOCs) at normal room temperature or in typical use. TPU's main advantage for phone cases is durability without the brittleness of hard plastics, though it can yellow or become sticky over years of UV exposure.
The brand's record and disclosure
Mous has not published a formal PFAS policy or third-party safety certification (e.g., OEKO-TEX or similar standards) for this product. The brand does not advertise chemical testing results or restrictions for heavy metals or plasticizers. No product recalls or safety violations have been established in public records for Mous phone cases. Transparency on material sourcing and manufacturing controls is limited compared to premium brands that publish compliance statements.
How it compares in its category
TPU cases are the category standard for waterproof phone protection and carry lower chemical risk than silicone cases (which may contain uncrosslinked polymers) or polycarbonate blends (which may contain BPA-based additives). Hard plastic cases often include colorants and UV stabilizers that can leach under heat; TPU avoids many of these. Mous cases compete directly with OtterBox and Spigen products, most of which also use TPU without published third-party chemical certification.
If you buy it
Store the case at room temperature and avoid prolonged direct sunlight, which accelerates yellowing and surface degradation. Do not intentionally heat the case or leave it in hot vehicles, as TPU softens above 60, 70°C. Wipe with mild soap and water; avoid harsh solvents or abrasive scrubbing. Replace if cracks appear or if the surface becomes sticky or flaking, which indicates polymer breakdown.
