OXO Good Grips POP Container 6-Piece Bulk Set
Lower-concern food storage; no PFAS red flags on known materials, but OXO makes no explicit commitment.
OXO POP containers are primarily rigid polypropylene plastic and glass, materials not commonly associated with PFAS use. The brand discloses no PFAS-related information, yet the product has no signals of water-repellent coatings, nonstick finishes, or grease-resistant treatments that would invite PFAS chemicals.

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
This set combines polypropylene (PP, plastic #5) containers with glass lids. Polypropylene is a thermoplastic chosen for food storage because it does not contain BPA, BPS, or phthalates by formulation. PP is stable at typical kitchen temperatures and does not leach plasticizers under normal use. The glass lids eliminate contact between food and plastic during storage, further reducing any theoretical migration risk.
The brand's record and disclosure
OXO is a mainstream consumer products brand owned by Helen of Troy and has operated under standard FDA food-contact material compliance for decades without major safety recalls tied to leaching or chemical migration in food storage lines. The brand does not publish explicit materials disclosures or third-party safety certifications for this product line. No documented controversies exist regarding BPA, phthalates, or heavy metal contamination in OXO food storage containers.
How it compares in its category
OXO POP containers sit in the mid-market segment alongside Rubbermaid and Pyrex alternatives. PP-based food storage is standard across this category and carries equivalent chemical safety profiles. Glass-lid hybrid designs (like this set) are common and represent a slight safety advantage over all-plastic alternatives by reducing polymer contact time. No category-specific advantage or disadvantage applies to OXO's formulation relative to comparable competitors.
If you buy it
Polypropylene remains safe for cold and room-temperature storage indefinitely. Do not use these containers in the microwave or oven if the lids are attached, as PP softens around 100-140 degrees Celsius. Replace containers if the plastic becomes cloudy, cracked, or visibly degraded, as microscopic fractures can create leaching surfaces. Hand wash or use the top dishwasher rack to extend lid seal integrity; the glass lids themselves are durable but may develop stress fractures if subjected to thermal shock.
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 and phthalate leaching
Polypropylene does not contain BPA or phthalate plasticizers by chemistry. No documented cases of migration from OXO PP food storage containers exist in public safety databases.
Polymer degradation and microplastics
Over extended use (years), PP containers may develop microscopic cracks or stress whitening, particularly if subjected to repeated dishwasher cycles or rough handling. Degraded surfaces could theoretically release microplastics into stored food, though risk is low under normal conditions.
Heat-induced leaching during misuse
While PP is food-safe at room temperature, heating beyond 100-140 degrees Celsius (microwave, oven, boiling water) can soften the plastic and potentially increase migration of residual monomers or additives. This is a user-behavior hazard, not a manufacturing defect.
Glass lid breakage and sharp fragments
Glass lids on food storage containers carry inherent breakage risk in multi-piece sets. OXO does not publish breakage rates or safety documentation specific to this product. Impact or thermal stress (dishwasher cycling) may cause cracks or shattering over time.
Latch degradation and seal failure
The POP container locking mechanism uses polymer hinges and latches that may weaken after 100-200 open-close cycles. Seal failure does not pose a chemical hazard but compromises food freshness and allows pest entry or cross-contamination.
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.
