Old Navy Women's High-Waisted Pixie Pants
Lower concern. Bare cotton-blend pants without stain or water treatment.
Old Navy does not disclose PFAS use in this product. Cotton-blend pixie pants lack water-resistant or stain-resistant finish, reducing typical PFAS treatment risk. No lab data available.

The full breakdown
What it's made of and why it matters
Old Navy Pixie Pants are a cotton-polyester blend woven twill, typically 88% cotton and 12% polyester or similar ratios. Cotton dominates the fiber content, which reduces synthetic chemical exposure compared to fully synthetic pants. The polyester component is a stable thermoplastic polymer that does not leach significantly under normal wearing conditions, though the dye system and any finishing treatments applied during manufacture are the main chemical concern in this product category.
The brand's record and disclosure
Old Navy (Gap Inc. subsidiary) has not published formal chemical disclosure statements or restricted substance lists specific to apparel lines, and maintains a general sustainability statement rather than granular transparency on hazardous finishes. The brand has faced no major recalls or public hazard allegations related to apparel formaldehyde, azo dyes, or heavy metals in recent years. Gap Inc. does participate in industry water and chemical stewardship initiatives, but Old Navy does not independently certify products to third-party textile standards such as OEKO-TEX or GOTS.
How it compares in its category
Standard cotton-blend pants occupy the middle of the safety spectrum: they avoid the VOC off-gassing risks of heavily treated synthetics or water-repellent coatings, but lack the independent verification of certified organic or OEKO-TEX labeled alternatives. Old Navy's price point and material choice are typical for mass-market apparel, with safety profiles broadly equivalent to competitors like Target, H&M basic lines, and Uniqlo; no data suggests Old Navy has worse chemical controls than these peers.
If you buy it
Wash these pants in cool water before first wear to reduce any residual dyes or finishes. Standard machine washing and drying present no heat risk; twill fabrics are robust and do not shed microplastics significantly under normal laundry. No special care is needed beyond routine garment maintenance. Replace when seams fail or fabric pilling becomes severe, not due to chemical degradation concerns.
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.”
Azo dyes and heavy metal dye contamination
No recalls or test reports of azo dye violations or heavy metal (lead, cadmium, chromium) contamination in Old Navy apparel have been published. Mass-market dyers typically comply with legal azo restrictions in major markets, though third-party audits are not publicly available for this brand.
Formaldehyde resin finishes
Cotton-blend twill may receive wrinkle-resistant or sizing finishes during manufacturing that could contain formaldehyde-releasing resins. Old Navy does not disclose finish specifications; however, such treatments are standard industry practice and off-gas minimally after initial wash and brief airing. No specific testing of Old Navy products has been published.
Antimony in polyester fiber
The 12% polyester content uses antimony trioxide as a catalyst in polymerization; however, antimony is chemically bound into the polymer chain and does not leach during wearing or washing under normal conditions. No health hazard from antimony migration in standard polyester apparel is documented.
Flame retardant treatments
Pixie Pants are standard everyday trousers without flame-resistant labeling and are not subject to flammability standards requiring additive flame retardants. No flame retardant chemical additives are expected in this product.
Microplastic shedding
The 12% polyester component will shed some synthetic fibers during washing, as all polyester garments do. The impact is incremental; a cotton-dominant blend sheds considerably less than 100% polyester alternatives. Washing in a microfiber capture bag reduces shed slightly but does not eliminate it.
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.
