The full breakdown
What it's made of and why it matters
VOS case is plastic (likely TPU or silicone blend) with an undisclosed waterproof coating. The coating is the critical unknown: waterproofing in phone cases typically relies on polyurethane, acrylic, or Teflon-family coating layers, each with different safety profiles. Without manufacturer transparency on coating type, you cannot rule out Teflon-type coating (Teflon-like) or other persistent compounds. The plastic base itself is not inherently hazardous, but degradation over time or exposure to heat can leach additives.
The brand's record and disclosure
Anccer (Encore Brandz) maintains minimal public disclosure on material composition or safety certifications. No published third-party testing, BPA-free claims, or PFAS statements are on record for this product line. The brand does not appear in major safety databases or certification registries (CE, FCC, CPSIA compliance details are unavailable). This silence is typical of mass-market phone accessories but limits your ability to verify what chemicals are present.
How it compares in its category
Phone cases compete on durability and waterproofing; most brands in this price tier use similar opaque plastic-plus-coating formulations. Premium alternatives (e.g., OtterBox, Spigen) often disclose material certifications or at minimum publish teardowns; budget brands like Anccer rarely do. The green color adds a small dye risk, though plasticizer-based colorants are industry standard and rarely flagged as hazardous in non-food contact use. Compared to fabric or metal cases, plastic waterproof cases carry higher chemical disclosure risk.
If you buy it
Avoid prolonged skin contact with the case surfaces, especially for children or those with sensitive skin (undisclosed dyes and coatings can irritate). Do not expose to direct heat (car dashboards, direct sunlight for hours) as plastic softening accelerates leaching. Do not place the phone or case in mouths or near food. Wash hands after handling new cases and allow off-gassing for 24-48 hours in open air. Replace if the coating cracks, peels, or degrades; this signals barrier failure and increased leaching risk.
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.”
Undisclosed waterproof coating (Teflon-family coating or polyurethane)
Waterproof phone cases commonly use Teflon-type coating, polyurethane, or acrylic coatings. Teflon-type coating-based coatings can emit fumes when heated and may contain PFAS (graded separately at 40/100). Without manufacturer confirmation, risk is unquantifiable but standard for this product type.
Plastic base additives (plasticizers, stabilizers)
TPU or silicone phone case bases do not routinely contain phthalates or BPA in modern production, but Anccer does not publish material certificates. Exposure risk is low in non-food contact use, but undisclosed additives prevent full assessment.
Synthetic dye (green colorant)
Green plasticizer-based dyes are not regulated for phone cases (non-food contact). Azo dye concerns are primarily relevant in textiles and cosmetics; plastic colorants rarely trigger hazard flags, but skin contact over time could theoretically cause minor irritation in sensitive individuals.
Coating degradation over time
Waterproof coatings on budget phone cases typically degrade within 12-24 months of use. Peeling, cracking, or thinning increases leaching of underlying plastic compounds and reduces waterproof function. Replacement is recommended upon visible wear.
Heavy metals in coating or pigment (low probability)
Phone cases are not food contact items and heavy metal contamination in plastics is rare in developed supply chains. No recalls or reports for Anccer phone cases on this hazard are on record. Risk is minimal but unverifiable without testing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
