Rubbermaid Brilliance 20-Piece Food Storage Container Set
Lower concern for typical use; rigid plastic food storage without coatings carries minimal PFAS risk.
Rubbermaid Brilliance containers are made from polypropylene (PP), a non-halogenated plastic with no inherent PFAS. The brand makes no PFAS disclosure either way. No public lab data confirms PFAS in this product line.

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
This set uses polypropylene (PP, #5 plastic), a thermoplastic polymer chosen for food storage because it resists degradation at typical refrigerator and moderate microwave temperatures. PP does not contain BPA or phthalates by design, making it chemically simpler than earlier polycarbonate or PVC alternatives. The lids typically contain polypropylene or elastomer seals; no enamels, glazes, or non-stick coatings are present that would introduce lead, cadmium, or Teflon-type coating fume risk. Over decades of consumer use, PP has shown minimal leaching of monomers or additives under normal food storage conditions.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) does not publish detailed material safety disclosures or third-party certifications for this product line on their website. The brand has no major recalls or contamination incidents on record for the Brilliance food storage line. Rubbermaid maintains general compliance with FDA food contact regulations and does not explicitly tout toxin-free or phthalate-free messaging, which is typical for established mainstream brands confident in PP safety. No independent certifications (e.g., Cradle to Cradle, GreenGuard) are marketed for this specific product.
How it compares in its category
PP rigid containers are industry standard for food storage and carry lower chemical risk than soft plastics, glass (thermal shock/breakage risk), or melamine (formaldehyde resin concern). Rubbermaid Brilliance sits in the mid-market segment: less transparent disclosure than premium eco brands like Pyrex or OXO, but no known material quality or safety gaps versus competitors at its price point. Stackable design and moderate durability make it typical for mass-market food storage; no structural or material advantages or disadvantages that meaningfully shift hazard profile.
If you buy it
Avoid prolonged heating of containers themselves in microwave (transfer food to microwave-safe glassware if heating); short reheating cycles are acceptable. Do not use in oven or dishwasher on high heat, as PP softens above 120°C and may degrade seals. Inspect lids and container walls yearly for cloudiness, cracks, or lingering odors; discard if visible wear occurs, as micro-cracks can harbor bacteria. Store away from direct sunlight and heat sources to slow polymer aging; replace every 2, 3 years if used daily.
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 phthalates
Polypropylene (#5) does not use BPA or phthalates in its formulation. No instances of contamination or undisclosed additives have been reported for Rubbermaid Brilliance containers.
Microplastic leaching when heated
PP can shed microfibers or small polymer fragments when exposed to high heat, mechanical stress, or repeated microwaving. Risk is minimal in normal cold/ambient storage but increases if containers are heated repeatedly or degraded; use moderation with microwave reheating.
Monomer and additive leaching
PP monomer (propylene) does not leach into food at refrigerator or room temperature under standard conditions. Stabilizers and colorants used in food-grade PP are tightly regulated by FDA; no known leaching issues documented for this brand or product line.
Mold and bacterial growth
Lid seals and container crevices can harbor water and bacteria if not dried thoroughly after washing. This is a maintenance issue, not a material hazard; regular cleaning and air-drying mitigate risk.
Coating or glaze contamination
These containers have no ceramic glaze, enamel, or non-stick coating, eliminating risk of lead, cadmium, or Teflon-type coating exposure. The plastic itself is the food-contact surface.
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.
