The full breakdown
What it's made of and why it matters
Rearz Ultimate uses a cellulose and superabsorbent polymer (SAP) core, plastic backsheet, and waterproof barrier layers. The cellulose and SAP themselves are low-hazard materials widely used in period care. However, the waterproof layers that prevent leakage typically require hydrophobic coatings, and Rearz does not publicly disclose whether these contain PFAS (PFAS "forever chemicals") or safer alternatives. This opacity is the critical safety gap.
The brand's record and disclosure
Rearz has not published material safety data, ingredient transparency reports, or third-party certifications (such as Cradle to Cradle, GOTS, or STANDARD 100 by Oeko-Tex) that would clarify chemical composition. No major recalls for chemical contaminants have been publicly documented, but absence of disclosure is not the same as absence of risk. The brand's silence on PFAS and waterproof coating chemistry is a significant transparency failure for a product worn against skin.
How it compares in its category
Most mainstream period pads (Tampax, Kotex, Always) use similar cellulose/SAP cores but similarly do not disclose waterproof layer composition. Brands explicitly avoiding PFAS (such as Cora, Rael, and some organic lines) tend to publish third-party test results or certifications. Rearz's lack of differentiation on chemical safety puts it in the middle of a low-transparency category, not the worst but not a leader in disclosure.
If you buy it
Do not exceed manufacturer storage recommendations (typically 3-5 years) as polymer degradation over time may increase leaching risk. Store in a cool, dry place away from heat and humidity to prevent SAP breakdown. If you experience skin irritation, discontinue use and consider switching to a certified organic or PFAS-tested alternative. Request Rearz's waterproof coating safety data directly; consumer pressure for transparency is the only lever available.
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.”
PFAS in waterproof coatings
Undisclosed hydrophobic barrier layers in period pads commonly contain PFAS for water resistance. Rearz does not publish coating composition or test results, making PFAS presence unconfirmed but statistically probable for this product type.
Skin sensitizers in adhesives or fragrances
The 'Printed Mixed Pack' name suggests designs; printing inks and any fragrance additives are not disclosed. Standard adhesives and fragrance compounds can trigger contact dermatitis or allergic reactions in sensitive users.
Microplastics and plastic backsheet degradation
Plastic backsheet can degrade over time with heat, moisture, and friction, potentially shedding microplastics. No specific data on Rearz backsheet durability or polymer type is publicly available.
Chemical residues from manufacturing
No recalls or adverse reports for manufacturing contamination (solvents, bleach residues, dye contaminants) have been documented. Cellulose and SAP production is regulated, but Rearz does not publish process certifications.
Allergic reaction to dyes or pigments in printed designs
Printed motifs may use synthetic dyes or pigments; azo dyes and heavy metal pigments are not prohibited in this category. Rearz does not specify dye chemistry, creating unknown risk for sensitive skin.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
