Cacoe [floatable] Floating Universal Ipx8 Waterproof Phone Case 2
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes waterproofed TPU/silicone case, 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.
Microplastic shedding or material degradation
Like all elastomer cases, prolonged UV exposure or mechanical abrasion may cause microscopic particle release from the outer surface. This is a minor, non-toxic wear mechanism inherent to the material class, not a manufacturing defect unique to this brand.
Mold or bacterial growth in seals if water-sealed improperly
If seals trap moisture and the case is stored wet or in high-humidity conditions, fungal growth can occur in the crevices around port covers. This is a usage/maintenance issue, not a product defect; it is preventable through drying after water exposure.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Phthalates
TPU and silicone used in phone cases do not typically require phthalate plasticizers; modern TPU formulations rely on non-phthalate alternatives. No public testing or complaints specific to Cacoe cases document leaching into phones or skin contact.
Source, ATSDR ↗Lead
No recalls or testing data document heavy metal contamination in Cacoe cases. Silicone and TPU formulations meeting basic food-grade or medical-device standards do not require cadmium or lead pigments; modern colorants use iron oxides or organic dyes.
Source, ATSDR ↗Allergic contact dermatitis from silicone or TPU additives
Silicone and TPU are generally hypoallergenic; cases in this material class rarely trigger contact sensitization. No complaints or medical reports specific to Cacoe cases have been documented in public sources.
The full breakdown
What it's made of and why it matters
This case is constructed from thermoplastic polyurethane (TPU) and/or silicone elastomer, materials chosen for flexibility, water resistance, and impact absorption. Neither TPU nor silicone requires persistent chemical coatings to achieve waterproofing at the stated IPX8 rating; the waterproofing comes from material density and mechanical seals (port covers, adhesive edges) rather than applied water-repellent treatments. Both polymers are chemically inert under normal phone-use conditions and do not off-gas volatile compounds at room temperature.
The brand's record and disclosure
Cacoe is a minor consumer electronics accessory brand with minimal public transparency on material sourcing or chemical safety practices. No published certifications (ISO, OEKO-TEX, or equivalent) are on record for this product line. No recalls, safety violations, or health incidents attributable to this case have been documented in publicly available sources.
How it compares in its category
Waterproof phone cases in this price and material tier typically use TPU or silicone without additional chemical coatings, making them lower concern choices in personal electronics accessories. Premium alternatives (hard plastic + rubberized hybrid cases) may incorporate antimicrobial additives or flame retardants in the plastic shell; this case avoids those. Budget cases sometimes use lower-grade TPU with higher plasticizer content, but no evidence suggests Cacoe products fall into that group.
If you buy it
Store at room temperature away from direct sunlight, which can degrade silicone over years of exposure. Do not expose to prolonged heat above 60°C (140°F), as this may compromise the elasticity and water-seal integrity of the material. Check port covers and adhesive seams every 6-12 months for cracks or separation; replace the case if seals visibly degrade. Rinse with fresh water after saltwater or chlorinated-water contact to prevent material brittleness.
