Rubbermaid Brilliance Round Leak Proof Food Storage Containers (6-Pc.)
Lower PFAS concern for food storage, standard plastic containers, but Rubbermaid has not disclosed PFAS absence.
Rubbermaid Brilliance containers are made from polypropylene plastic and copolyester seals, materials not inherently associated with intentional PFAS addition. Food storage containers typically carry lower PFAS risk than cookware or water-resistant textiles.

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
The containers are polypropylene (PP, #5 plastic), a relatively stable food-contact polymer with low migration risk at normal refrigerator temperatures. The lid seal uses Tritan copolyester, a BPA-free engineering plastic designed for durability and repeated seal flexing. Polypropylene is food-approved by the FDA and does not leach under typical cold-storage conditions; Tritan similarly has no established migration issues in independent testing. These materials do not contain phthalates or BPA as formulated.
The brand's record and disclosure
Rubbermaid is owned by Newell Brands, a major kitchen-products manufacturer with no major food-storage recalls in the past decade. The company has not publicly committed to PFAS-free certification or independent third-party testing disclosure for this product line. Rubbermaid does not advertise PFAS absence, which reflects typical silence in the food-storage container market rather than a red flag. No formaldehyde, heavy metal, or microplastic contamination has been documented in this product or brand.
How it compares in its category
Rubbermaid Brilliance containers occupy the mid-market safety tier: polypropylene-based, no BPA, no phthalates, and no known migration issues under normal use. This is comparable to other major brands (Pyrex plastic, OXO Good Grips, Snapware) that use similar PP or Tritan formulations. They offer better documented stability than no-name or very low-cost containers, which occasionally carry undisclosed additives or recycled-plastic contaminants. Rubbermaid's lack of third-party PFAS testing is standard for the category, not a distinguishing weakness.
If you buy it
Store food at refrigerator temperature; do not microwave these containers, as polypropylene softens above 100 degrees Celsius and can release plasticizers. Hand-wash or use the top-rack of dishwasher on low heat; avoid prolonged hot-water soaking. Replace lids after visible cracking or warping to maintain seal integrity and prevent mold growth in the gap. Do not store fatty or acidic foods (oils, vinegar, citrus) for extended periods, as these can slightly increase polymer migration, though levels remain below regulatory concern thresholds.
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.”
Polypropylene thermal degradation and plasticizer migration
Polypropylene containers should not be heated above 100 degrees Celsius. Microwave use or hot-water storage can soften the polymer and increase additive release, though migration remains low under normal refrigerator use.
Lid seal degradation and mold colonization
Repeated flexing and washing of the Tritan copolyester seal can cause micro-cracking over 1-2 years, allowing water ingress and mold growth at the interface. This is a hygiene risk rather than chemical hazard.
BPA or phthalate leaching
Polypropylene and Tritan are formulated without BPA or phthalates as a matter of standard modern practice. No contamination has been documented in this product or brand.
Microplastic fragmentation in food
Polypropylene containers do not fragment into microplastics under normal cold storage or mechanical use. Risk is only present if containers are damaged, heated, or microwaved.
Heavy metal or cadmium contamination
Food-contact plastics like polypropylene and Tritan are not permitted to contain heavy metal pigments or stabilizers under FDA regulations. No such contamination has been reported in Rubbermaid products.
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.
