OXO Good Grips 3-Piece POP Round Container Set
Lower concern: rigid food-storage containers without nonstick or water-resistant coatings carry minimal PFAS risk.
OXO Good Grips POP containers are rigid plastic (ABS) storage vessels with snap-lock lids and silicone seals, no nonstick coating, water-repellent coating treatment, or reported Teflon-family coating components. OXO has made no public PFAS disclosure for this product line.

The full breakdown
What it's made of and why it matters
OXO Good Grips POP containers are made from ABS (acrylonitrile butadiene styrene), a rigid thermoplastic that does not contain BPA and is not designed with nonstick or water-resistant coatings. ABS is chemically stable at typical food storage temperatures and does not leach significant amounts of monomers or additives under normal use. The silicone gaskets provide an airtight seal without relying on problematic elastomers; silicone is inert and food-grade approved across regulatory bodies.
The brand's record and disclosure
OXO is owned by Helen of Troy and has maintained a generally conservative approach to food-contact materials, with no major recalls or public safety controversies tied to leaching or contamination in food storage products. The company does not prominently disclose PFAS testing or water-resistance treatment specifics, but the POP line is marketed as straightforward rigid storage without premium water-resistant or nonstick claims that would trigger PFAS use. No independent testing has flagged OXO food containers for unexpected chemical migration.
How it compares in its category
Rigid ABS food containers occupy a middle ground: safer than soft plastics (which carry higher phthalate and microplastic risk when heated) and comparable to polypropylene (PP) in chemical stability, but less common than PP in commercial food storage. OXO's design emphasizes durability and airtight sealing over ultra-low cost, positioning it above budget alternatives that may use recycled or lower-grade plastic. Glass containers offer zero leaching risk but lack the shatter-resistance and portability of ABS.
If you buy it
Hand wash the containers and gaskets with warm soapy water; ABS is not dishwasher-safe at high temperatures and prolonged heat can degrade the plastic over years. Do not use for hot liquids above 140 degF (60 degC) or microwave; ABS will warp and may release small amounts of unreacted monomers under sustained heat stress. Replace gaskets every 2-3 years if they become loose or discolored, as silicone can absorb odors and oils and lose elasticity. Store away from direct sunlight to slow photo-oxidative aging of the plastic.
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.”
BPA/BPS and related bisphenols
OXO explicitly markets this line as BPA-free, and ABS formulations used in food contact do not routinely substitute BPA with BPS or other problematic bisphenols. No recalls or testing reports have identified bisphenol leaching from OXO POP containers.
Phthalates
ABS is a rigid plastic that does not require plasticizers such as phthalates to achieve its material properties. Silicone gaskets are not plasticized and do not contain phthalates.
Microplastic shedding
Rigid ABS containers do not typically shed microplastics during normal cold or room-temperature storage. Risk rises only if the plastic is repeatedly heated above its glass transition temperature (around 105 degC) or exposed to prolonged UV degradation, causing brittleness and potential fragmentation.
Unreacted ABS monomers (acrylonitrile, butadiene)
Well-cured ABS used in food contact is very low in residual monomers, but prolonged exposure to hot liquids or microwave use can accelerate minor migration. OXO does not disclose residual monomer testing; migration under normal cold or room-temperature storage is negligible.
Silicone gasket degradation
Over time (2-3+ years), silicone gaskets can absorb food odors, stains, and oils, and may lose elasticity, compromising the airtight seal. Replacement gaskets are widely available, but degraded gaskets do not pose a direct health hazard, only reduced functionality.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
