OXO Good Grips Container POP
Lower concern. Polypropylene food storage is not known PFAS-prone.
OXO POP containers use polypropylene plastic and silicone seals, neither commonly treated with PFAS. No public PFAS disclosures or certifications exist for this product line.

What OXO Good Grips Container POP is made of, ingredients and materials
The OXO Good Grips POP container is injection-molded polypropylene (PP, #5 plastic), a thermoplastic polymer chosen for food storage because it resists moisture, does not readily leach chemicals, and withstands moderate heat (up to approximately 100-110°C / 212-230°F). The silicone gasket seal is an elastomer that resists degradation and does not off-gas volatile compounds under normal refrigerator or pantry storage. Polypropylene is approved by FDA for direct food contact and is not a material linked to PFAS.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Microplastics
If the container is repeatedly heated near its upper temperature limit or exposed to acidic foods over years, microscopic PP particles may migrate. Risk is low under normal refrigerator or pantry storage; higher if misused in hot environments or damaged.
Source, EPA ↗Microbial growth in gasket seal
The silicone gasket can trap moisture and food residue if not cleaned thoroughly, creating a microenvironment for mold or bacteria. This is a maintenance issue, not a material toxicity concern; regular hand-washing of the gasket minimizes risk.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Polypropylene formulations do not typically contain BPA or BPS. No reports of these compounds leaching from OXO POP containers into food.
Source, FDA ↗Phthalate plasticizers
PP is a naturally rigid plastic and does not require phthalate plasticizers. The silicone gasket is not phthalate-prone. No documented phthalate migration from this product.
Silicone gasket degradation and off-gassing
Food-grade silicone is stable and does not release volatile organic compounds under normal storage conditions. Silicone can absorb food odors and oils but does not leach chemical compounds into food.
The full breakdown
The brand's record and disclosure
OXO has no public recalls or safety warnings specific to the POP container line. The company does not publicly disclose detailed material sourcing or chemical composition beyond basic product specifications. OXO has not made prominent public statements on PFAS avoidance, though its focus on kitchen and food-storage products suggests awareness of food-contact safety norms. No third-party certifications (BPA-free labels, Cradle to Cradle, etc.) are prominently marketed for this line, though polypropylene formulations typically do not contain BPA.
How it compares in its category
Polypropylene food containers are industry-standard with lower concern than older polycarbonate (PC, #7) or polyvinyl chloride (PVC, #3) alternatives. OXO's sealed design and silicone gasket reduce air exposure and food-to-plastic contact time compared to open storage bowls or containers with plastic-only seals that can degrade. Glass or stainless-steel containers offer marginally lower chemical leaching risk in theory, but for typical pantry use (dry goods, cool storage) the PP POP container represents a mainstream choice for food storage with no hazard of this kind on record.
If you buy it
Avoid prolonged exposure to heat above 100°C (212°F) and do not use in ovens or under direct flame. Hand-wash the silicone gasket periodically to prevent mold or bacterial buildup in the seal; dishwasher-safe designation applies to the container body but gaskets benefit from manual cleaning. Do not store fatty or oily foods at high temperatures, as prolonged heat can slightly increase polymer migration. Replace the gasket if it becomes visibly cracked, discolored, or odorous, as silicone degradation may allow seal failure.
