Samsung Galaxy S23 Series Waterproof Phone Case

F · High PFAS

Skip until Samsung discloses waterproofing chemistry.

Verdict: SkipTPU/silicone case is chemically stable and low-risk for non-PFAS hazards, but Samsung's silent stance on waterproofing chemistry and unconfirmed PFAS use demands disclosure before confident purchase.

Samsung does not publicly disclose PFAS use or absence in this case's waterproof coating. Waterproof phone cases commonly use water-repellent coating treatments that may contain PFAS; no lab data available for this model.

The full breakdown

What it's made of and why it matters

Samsung Galaxy S23 cases are constructed from thermoplastic polyurethane (TPU) or silicone elastomer blended with additives for waterproofing and durability. TPU is a durable, flexible polymer with low toxicity in its base form, commonly used in phone cases and outdoor gear. The waterproof treatment chemistry is not publicly detailed by Samsung, this is the critical gap, as waterproofing often involves fluorinated compounds (PFAS or alternatives) applied to seal the material's surface.

The brand's record and disclosure

Samsung has not publicly disclosed the specific waterproofing agent or coating used in this case. The company has faced pressure on PFAS use in textiles and has committed to phasing PFAS in some product lines by 2025, but accessory lines remain opaque. No third-party testing or certification (e.g., OEKO-TEX, bluesign) for this case has been published, limiting independent verification of chemical composition.

How it compares in its category

Most OEM phone cases (Apple, Google, OnePlus) also do not disclose waterproofing chemistry, making Samsung's silence typical rather than exceptional. Third-party alternatives from brands like Spigen or OtterBox rarely disclose PFAS status either, though some now label 'PFAS-free' waterproofing. This category-wide opacity means purchasing any waterproof phone case carries similar transparency risk.

If you buy it

Store the case away from heat sources and direct sunlight to minimize potential off-gassing of volatile additives. Do not microwave or place in high-heat environments. Inspect quarterly for discoloration, stickiness, or odor, signs of degradation that warrant replacement. Wash hands after prolonged contact, especially if case shows visible wear, to avoid skin contact with any degraded coating particles.

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.”

Possible

Volatile organic compounds (VOCs) from elastomer additives

TPU and silicone cases may off-gas plasticizers, UV stabilizers, or waterproofing additives, particularly when new or exposed to heat. Samsung has not disclosed additive packages, so individual chemical risk cannot be assessed.

Possible

Skin irritation from contact with uncured or degraded coating

If waterproofing treatment involves reactive surface coatings, residual monomers or degradation byproducts could cause localized dermatitis with prolonged skin contact. Risk increases if case is used intensively or stored in warm conditions.

Reported

Microplastic shedding from mechanical wear

Silicone and TPU cases degrade over time with daily handling and can shed microparticles. This is a general property of elastomers, not unique to Samsung, but contributes to personal exposure and environmental release.

None known

Heavy metals in pigmentation (if colored case)

No recalls or public testing data specific to Samsung S23 cases for lead or cadmium in colorants. Color-formulation standards for phone cases are largely unregulated unless case is marketed for children.

Likely

Waterproofing chemistry (PFAS or substitute) not disclosed

Waterproof elastomeric coatings almost always require either PFAS or emerging fluorine-free alternatives. Samsung's silence suggests either PFAS use (not yet disclosed) or a proprietary alternative (also not disclosed). Without confirmation, PFAS presence cannot be ruled out.

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.
