OXO POP Container Baking Set
Lower concern; basic plastic food storage without known PFAS triggers, but OXO provides no transparency on coatings or treatments.
OXO POP containers are rigid plastic storage with snap-lock lids designed for dry goods. The main risk factors like nonstick coatings, water-repellent treatments, and stain-resistant finishes don't typically appear in basic food-storage canisters. OXO makes no public disclosure about PFAS or coating chemistry.
We flunk more products than we pass. This one earned its grade. How we grade
Material
Plastic (polypropylene/polycarbonate) food storage containers and lids
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Microplastic shedding from wear
Repeated opening/closing and hand-washing can cause fine plastic particles to detach from the container edges and seals over time, especially if lids are used roughly or stored in damp conditions. Risk is low with normal use but increases with product age.
Lead
OXO POP lids use silicone or rubber gaskets that can crack, shrink, or lose elasticity after 3-5 years of use or exposure to dishwasher heat. A compromised seal allows moisture and contaminants to enter stored foods, especially in baking mixes prone to absorbing humidity.
Source: ATSDR ↗Chemical absorption and odor/flavor transfer
Polypropylene absorbs volatile compounds from strong-smelling foods and cleaning products over time. OXO containers are not immune to this; extended storage of spiced or acidic foods may leave persistent odors and taste residue in the plastic, though no toxicity results directly.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
BPA & bisphenols
OXO has not disclosed whether lids contain BPA or BPS. Polycarbonate used in some OXO lids may have carried BPA in older formulations, but modern batches are assumed BPA-free by industry standard. No leaching incidents are documented for this product line.
Source: FDA ↗Phthalate plasticizers
Polypropylene does not require phthalates for flexibility. If polycarbonate or acrylic is used in lids or seals, phthalates are unlikely in food-contact formulations subject to FDA oversight, but OXO does not confirm absence.
The full breakdown
What it's made of and why it matters
The OXO POP Baking Set uses polypropylene (PP) for the main containers and polycarbonate (PC) or acrylic for lids/seals. Polypropylene is one of the safest plastics for food contact because it has a high melting point (around 130°C / 266°F) and does not leach BPA or phthalates under normal kitchen conditions. Polycarbonate, if present in lids, carries older concerns about bisphenol A (BPA), though modern OXO products typically use BPA-free formulations, though the company does not publicly specify this for all lines.
The brand's record and disclosure
OXO is a subsidiary of Helen of Troy and has a reputation for practical, durable kitchen products. The company has not published comprehensive chemical disclosure statements or third-party certifications (such as NSF or FDA compliance documentation) readily available to consumers. No major recalls or contamination incidents specific to the POP container line are documented in public safety databases. OXO remains silent on PFAS treatments or coatings, which is typical for mainstream food storage brands but leaves a transparency gap.
How it compares in its category
OXO POP containers occupy the mid-range of the food storage market. They are more affordable than glass alternatives and more durable than thin single-use plastics, but offer less transparency than premium brands like Pyrex (glass) or Rubbermaid Brilliance (which publishes material specs). Compared to budget PP containers, OXO's design and seal quality are notably stronger, reducing the risk of lid degradation and microparticle release over time.
If you buy it
Do not microwave these containers unless the label explicitly permits it; polycarbonate lids can degrade under heat. Store dry goods (flour, sugar, baking supplies) rather than acidic or fatty foods for extended periods, as plastics can absorb odors and flavors. Hand-wash with warm water and mild soap; avoid abrasive scrubbers that scratch the surface. Replace containers every 3-5 years or if lids no longer seal tightly, as wear can compromise freshness and invite microbial growth.

Safer alternatives in Food Storage Containers
Pyrex
Glass Meal Prep Set
borosilicate glass with metal lids (likely stainless steel or aluminum)
Metal lid corrosion and leaching
Limited concern
Silicone or rubber gasket degradation
Moderate concern
Thermal shock fracture from glass
Moderate concern
Lower PFAS concern; glass meal prep containers are inherently a safer material choice.
⚠Risky category by default
Pyrex
Freshlock 10-Piece Glass Storage Set
Borosilicate glass containers with plastic lids (PP/TPE closure material unspecified)
Microplastics
Limited concern
Additive migration from plastic lids
Limited concern
Glass breakage and physical injury
Moderate concern
Bacterial growth in degraded or poorly sealed lids
Limited concern
Lower PFAS concern; glass containers are inherently low-risk; check lid material if possible.
⚠Risky category by default
Pyrex
6-Piece Food Storage Container Set
borosilicate glass with plastic lids
Plastic lid degradation and replacement necessity
Limited concern
Microplastic shedding from lids under heat stress
Limited concern
Undisclosed chemicals in lid coatings or gasket materials
Limited concern
Borosilicate glass breakage and cut hazard
Moderate concern
Lower PFAS concern; borosilicate glass containers pose minimal risk; plastic lids warrant standard caution.
