Nite Ize RunOff Waterproof Phone Case
Waterproof phone cases often use PFAS coatings. Unknown treatment raises concern.
Nite Ize RunOff cases provide waterproofing via unspecified coating. Brand discloses no PFAS information, typical for consumer electronics accessories.

What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
other is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Waterproof coating leaching (unidentified chemistry)
The specific coating formula is not disclosed. If PFAS-based (likely but unconfirmed), degradation or abraded contact could release fluorinated compounds. If non-PFAS, composition remains unknown and may include other fluorine alternatives not yet fully characterized for safety.
Plastic shell degradation and microplastic shedding
TPU and similar elastomers can degrade under UV exposure, heat, or mechanical stress, potentially shedding microplastic particles. Risk is low during normal phone-case use but increases if the product is dropped repeatedly or exposed to UV.
Skin sensitization from coating contact
Some waterproof polymer coatings or additives (plasticizers, catalysts) may trigger contact dermatitis in susceptible individuals. No specific incidents are on record for this product, but prolonged skin contact with worn or damaged coatings should be minimized.
What’s reassuring
Azo dyes or colorants in plastic shell
If the case is dyed (most are black or neutral), standard azo screening typically occurs in phone-case manufacturing, though Blackview does not publicly commit to restricted-substance standards. Risk is very low but not formally verified.
Off-gassing or volatile compounds from adhesives or solvents
New plastic cases may emit mild odors during initial use; this is common and usually harmless, dissipating within days. No health incidents are documented for Nite Ize cases, and TPU is generally low-VOC.
The full breakdown
What it's made of and why it matters
This case uses an unspecified waterproof coating applied to a plastic shell, likely TPU (thermoplastic polyurethane) or similar elastomer common in phone protection. Waterproof coatings on consumer goods frequently rely on PFAS (PFAS "forever chemicals") to repel water and oils, though manufacturers rarely disclose the chemistry. The base plastic itself is not inherently hazardous at room temperature, but the coating's composition and stability over time are opaque.
The brand's record and disclosure
Blackview is a Chinese smartphone manufacturer that has not published transparency reports or PFAS reduction commitments on the public record. The brand maintains silence on waterproof coating chemistry, which is typical of budget accessory suppliers but indicates no proactive safety communication. No major recalls or safety controversies specific to Blackview phone cases have been documented, though this reflects limited regulatory scrutiny of the product category rather than proven safety.
How it compares in its category
Waterproof phone cases compete on cost and durability; most budget options use undisclosed coatings to meet water-resistance standards cheaply. Premium alternatives (e.g., OtterBox, Lifeproof) sometimes reference fluorine-free or restricted-substance policies, though specifics vary. Nite Ize products are generally positioned as affordable, which often correlates with less rigorous chemical management than premium brands.
If you buy it
Keep the case away from heat (do not leave in direct sunlight for extended periods or in hot vehicles), as coatings may degrade and risk leaching into skin contact areas. Inspect regularly for cracks, peeling, or delamination, especially around seams; replace if visible damage occurs. Wash your hands after extended contact if the coating shows wear. Do not expose the case to prolonged contact with oils, solvents, or alcohol-based products, which can accelerate coating breakdown.
