Rubbermaid Brilliance Leak Proof Food Storage Containers
Lower PFAS concern for basic food storage, but no transparency from brand.
Rubbermaid Brilliance containers are rigid polypropylene with no disclosed surface treatments, coatings, or non-stick features, typical materials for dry/cold food storage carry lower inherent PFAS risk. However, Rubbermaid makes no public statement about PFAS-avoidance, and the lid seals may contain unknown additives.

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.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Rubbermaid Brilliance uses polypropylene (PP, #5 plastic) for both container and lid. Polypropylene is a thermoplastic with relatively stable polymer bonds and does not contain BPA, BPS, or phthalates by design. It has a melting point around 130-180°C, making it suitable for cold and room-temperature food storage, though repeated heating can degrade the polymer and potentially cause microplastic release over years of use.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) does not publicly disclose PFAS testing or certification status for this product line, nor does it provide detailed material safety data sheets for consumer-facing containers. The brand has no known major food storage recalls related to leaching or material failure, suggesting adequate quality control, but the silence on emerging contaminants like PFAS limits consumer trust. No third-party certifications (BPA-free claims, etc.) appear on standard product labeling.
How it compares in its category
Polypropylene containers are a mid-tier choice in food storage safety. They carry lower leaching risk than polycarbonate (#7) or older PVC, but slightly higher degradation risk than glass or stainless steel alternatives. Rubbermaid Brilliance is mainstream; comparable PP containers from OXO, Glad, and store brands perform similarly with no major differentiation in reported hazards. Glass alternatives eliminate plastic-related concerns but are heavier and breakable.
If you buy it
Avoid prolonged microwave heating; polypropylene tolerates brief reheating but is not designed for hot oven use. Replace containers if lids become cloudy, cracked, or discolored, as this signals polymer breakdown and potential microplastic shedding. Hand wash rather than dishwash when possible to extend lid seal integrity. Store fatty or acidic foods (oils, vinegar, citrus) in glass alternatives if you plan to keep them longer than a few months, as PP can soften slightly with prolonged contact.
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.”
Microplastics from polymer degradation
Polypropylene is durable but not immune to degradation over years of use, especially with repeated heating, freezing, or dishwasher cycles. Visible cloudiness or brittle lids signal advanced degradation; at this stage, microscopic plastic shedding into food is plausible but not quantified for this specific product.
BPA or BPS leaching
Polypropylene does not require BPA as a plasticizer and Rubbermaid does not add it. No reports of BPA or BPS in this product line exist in published recalls or third-party testing.
Phthalates
Polypropylene is not formulated with phthalate plasticizers; this hazard is not relevant to PP-based containers.
Lid seal degradation and food contact loss
Some user reports note that Rubbermaid Brilliance lids lose sealing integrity after 1-3 years of use, though this is a functional rather than safety issue. Compromised seals can allow air exposure, promoting mold or bacterial growth, rather than direct leaching.
Heavy metals in colorants or additives
No lead, cadmium, or other heavy metals have been reported in polypropylene food containers from Rubbermaid. Polypropylene is generally free of intentional heavy metal additives in mainstream manufacturing.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
