Rubbermaid Brilliance 36-Pc. Food Storage Set
Lower concern for food storage; rigid plastic containers unlikely to contain PFAS, but brand discloses nothing about PFAS or coatings.
Rubbermaid Brilliance containers are rigid, durable plastic food storage without flexible films or treated surfaces. No PFAS coatings or water-resistance treatments typically appear in rigid food-grade plastic. Rubbermaid provides no public PFAS disclosure, and independent lab testing is unavailable.

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.
Microplastics
Polypropylene containers can fragment or leach microparticles if cracked, scratched, or repeatedly microwaved despite warnings. Risk is low with proper storage and handling but increases with age and misuse.
Source: EPA ↗Heat-induced leaching
Polypropylene can release oligomers and other compounds at elevated temperatures (above 160F). This product is not designed for hot food storage or microwave use; using it outside these limits increases potential for leaching.
Lid seal degradation
Rubber or silicone gaskets in lids degrade over time and with repeated washing, reducing airtightness. This is normal wear rather than a chemical hazard but can compromise food freshness and hygiene if not replaced.
Mold/bacterial growth from poor ventilation
Sealed containers trap moisture; improper drying before storage or leaving condensation inside can promote microbial growth. This is a use-related risk, not a product defect, but common with this container type.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Phthalates
Polypropylene and copolyester do not typically contain phthalates. No public record of phthalate contamination in Rubbermaid Brilliance products or similar mainstream PP food storage containers.

What it's made of and why it matters
Rubbermaid Brilliance containers are made from polypropylene (PP) and copolyester blends, both of which are rigid plastics chosen for durability and food contact safety. Polypropylene is one of the most stable food-contact plastics and does not contain BPA or BPS by design. The copolyester component (likely acrylic or similar) is added for clarity and impact resistance. This material combination is resistant to leaching under normal cold and room-temperature storage conditions.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) markets Brilliance as BPA-free and compliant with FDA food-contact regulations, but provides no public disclosure regarding PFAS, phthalates, or other chemical restrictions beyond the BPA claim. The brand has not faced major recalls or safety controversies specific to this product line in available public records. However, like most major plastic container manufacturers, Rubbermaid remains largely silent on PFAS mitigation or independent third-party safety certifications.
How it compares in its category
Brilliance sits in the mainstream mid-market segment alongside Pyrex glass and OXO plastic containers. Unlike glass, it offers break resistance and lower cost; unlike some budget alternatives, it uses recognized safer plastics (PP rather than PVC or polycarbonate). No independent testing or recalls distinguish it as safer or less safe than comparable rigid plastic food storage sets from major manufacturers in this price range.
If you buy it
Store only cold or room-temperature foods; avoid microwave use or sustained heat above 160F, as polypropylene begins to soften and may degrade. Hand-wash lids and inspect regularly for cracks, cloudiness, or warping, discard and replace if structural integrity is compromised. Do not store fatty or oily foods long-term, as they can stress the plastic over time. Lids should be replaced every 2-3 years if frequently used, as they wear faster than 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

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.

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.
