Rubbermaid Brilliance Glass Food Storage Set
Lower-concern choice, glass container with untreated plastic lids, no PFAS-prone coatings identified.
Rubbermaid Brilliance is a glass food storage set with polypropylene snap lids. Glass itself carries no PFAS risk; PP lids are not inherently treated with Teflon-family coating or water/grease repellents known to contain PFAS. Rubbermaid makes no PFAS claims either way, and no third-party testing or recalls flagged this product.

The full breakdown
What it's made of and why it matters
Rubbermaid Brilliance uses borosilicate glass for the containers themselves, which is chemically inert and does not leach compounds into food under normal storage or mild heating. The lids are polypropylene (PP, plastic #5), a thermoplastic chosen for its higher melting point (~160°C) compared to other common food-contact plastics. Borosilicate glass is also thermal-shock resistant, meaning it tolerates temperature swings better than standard soda-lime glass. The combination avoids the most common leaching concerns associated with plastic-only or ceramic-glazed storage.
The brand's record and disclosure
Rubbermaid, owned by Newell Brands, does not publish detailed chemical or PFAS disclosure statements specific to the Brilliance line on their website. The brand has not faced documented safety recalls or enforcement actions tied to this product line as of public record. Rubbermaid does not market Brilliance containers as meeting independent third-party certifications (e.g., BPA-Free verified by NSF), though the use of glass and PP inherently avoids BPA concerns. The absence of transparency is typical for the category but reflects a passive rather than proactive safety communication posture.
How it compares in its category
Glass food storage containers are among the safest options available because glass itself does not leach. Brilliance sits in the mid-to-premium tier: glass containers alone are commodity items, but Brilliance's polypropylene lids with silicone seals and snap-lock closures offer durability and convenience compared to basic glass jars. Rival glass-based systems (e.g., Pyrex, OXO) are comparable in material safety, though some competitors offer higher-end options with stainless-steel or metal lids (eliminating plastic entirely). Versus plastic-only containers (e.g., Rubbermaid's own plastic lines or Tupperware), glass eliminates the BPA/BPS and phthalate leaching pathways that remain a concern in food storage plastics.
If you buy it
Store food at room temperature or refrigerated; glass is safe for freezing and microwave use, but do not expose lids directly to microwave heat or place lids in the oven. Replace lids every 1-2 years if silicone seals degrade, harden, or lose elasticity, as a poor seal can allow food spoilage rather than chemical contamination. Glass containers are durable but chip or crack if dropped, creating sharp edges; discard broken pieces entirely to avoid ingestion of glass fragments. Hand wash lids to extend silicone and plastic lifespan; dishwasher heat can accelerate lid degradation over time.
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 lid leaching (heat/time-dependent)
PP lids are stable at normal storage temperatures. Heat above 70°C or prolonged exposure to acidic foods may cause trace oligomers to migrate, though no published studies document this in Rubbermaid Brilliance specifically. Risk is significantly lower than with lower-grade plastics.
Silicone seal degradation and contamination
Brilliance lids use silicone gaskets to seal. Over years of use, silicone can absorb odors, discolor, or harden, potentially compromising seal integrity. No chemical toxicity is associated with Rubbermaid's silicone, but worn gaskets can allow food spoilage and mold growth.
Borosilicate glass breakage and sharp edges
Glass containers are brittle and prone to chipping or shattering on impact. Consumer reports confirm occasional breakage; sharp glass fragments pose a cutting and ingestion hazard. This is a physical rather than chemical risk, inherent to the glass material.
BPA or BPS in polypropylene lids
Polypropylene itself does not contain BPA (which is used in polycarbonate and some epoxy resins). No evidence suggests Rubbermaid adds BPA or BPS to Brilliance PP lids. This hazard is not a concern for this product.
Microplastic shedding from plastic lids
Repeated washing, stacking, and wear can cause polypropylene lids to shed microparticles, though the rate is slow and exposure from food storage containers is considered negligible compared to other sources. No specific data exists for Rubbermaid Brilliance lids.
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.
