Galaxy S22 Ultra Waterproof Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPE elastomer, silicone, 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 Galaxy S22 Ultra Waterproof Case is made of, ingredients and materials
The Galaxy S22 Ultra case is constructed from TPE (thermoplastic elastomer) and silicone, both petroleum-derived polymers chosen for flexibility, durability, and water resistance without requiring chemical coatings or sealants. TPE and silicone are chemically stable at room temperature and do not leach known toxins into skin or food contact. The waterproof rating comes from the physical seal design (gasket compression around device edges and button covers), not from surface treatments, which eliminates a major source of chemical migration.
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.
Bacterial or mold growth in seals
Any waterproof case traps moisture in the gasket channel if not dried after water exposure. This is a maintenance issue, not a product defect, but neglect can create unhygienic conditions. Regular cleaning prevents this.
TPE or silicone degradation and particulate shedding
Extended UV exposure or heat cycling can cause elastomer surface breakdown over years of use, potentially releasing small polymer particles. This is not acutely toxic but indicates end-of-life approaching; replacement is recommended.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Contact dermatitis or skin irritation
TPE and silicone are hypoallergenic for the vast majority of users. No dermatological incidents or allergen concerns are documented for this product category or brand.
Colorant or pigment toxicity
The brand's TPE cases use inert synthetic pigments that do not migrate into skin or liquids at room temperature. No heavy metal contamination has been reported in similar elastomer accessories.
Off-gassing of volatile organic compounds
TPE and silicone emit minimal VOCs compared to hard plastics or polyurethane foams. No odor complaints or headache associations are documented for this case or similar elastomer phone accessories.
How is this PFAS grade calculated?
The brand's record and disclosure
The brand has not published a dedicated PFAS elimination statement for phone accessories, though the company has made broader commitments to reduce chemical hazards in manufacturing. No recalls or contamination incidents are on record for this specific case model. The brand's transparency on phone case safety chemistry is minimal; they do not typically provide third-party testing reports or material safety data sheets for elastomer cases, which is standard industry practice but limits independent verification.
How it compares in its category
TPE and silicone cases are among those with lower concern in the phone-case category because they require no flame retardants, coatings, or dyes to achieve waterproofing. Hard plastic cases often use polycarbonate or polystyrene and may contain flame retardants or UV stabilizers; fabric-lined cases may off-gas formaldehyde. The case avoids these by relying on elastomer chemistry and mechanical design, placing it in the lower-risk segment.
If you buy it
Clean the case periodically with mild soap and water to maintain seal integrity and prevent bacterial buildup inside the gasket channel. Avoid prolonged exposure to direct sunlight or heat above 60 degrees Celsius, which can degrade elastomer flexibility over time. Replace the case if you notice tears, permanent compression, or water seeping into the device during water exposure. TPE and silicone do not require special disposal beyond standard recycling; they are not bioaccumulative.
