The Lola High Waist Period Underwear
Lower concern; PFAS-free certified, organic cotton base.
Lola period underwear uses organic cotton with MADE SAFE certification and third-party PFAS testing. Water-resistant coating is explicitly PFAS-free per brand claims.
Brand says: “PFAS-free formulation, certified by third-party testing”
We flunk more products than we pass. This one earned its grade. How we grade
Material
organic cotton with water-resistant treatment
Brand disclosure
Third-party verified PFAS-free
Lab data
No PFAS found in testing
What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
period care is a category where PFAS exposure is more common.
Water-resistant coating degradation and microplastic shedding
The non-PFAS water-resistant treatment (likely a polyurethane or silicone-based alternative) may shed microscopic fibers with heavy washing over years, though this risk is typical of all water-resistant textiles. Proper care (gentle wash, low heat) minimizes degradation.
Allergen sensitivity to cotton or treatment additives
Organic cotton itself is hypoallergenic, but residual dyes, finishes, or detergent buildup can trigger contact dermatitis in sensitive individuals. Prewashing and fragrance-free laundry reduce this risk.
What’s reassuring
Third-party PFAS-free verification
Independently verified PFAS-free by a third party.
No PFAS found in lab test
No PFAS detected in independent testing.
Formaldehyde / VOCs
Organic cotton typically avoids formaldehyde-heavy durable-press resins, and Lola does not advertise such finishes. No evidence of formaldehyde dyes or fixatives in this product.
Source: ATSDR ↗Azo dyes (textile colorants)
GOTS certification for organic cotton includes restricted azo dye standards. No known use of banned azo dyes in Lola products; brand transparency suggests compliance with OEKO-TEX or equivalent.
Antimony in synthetic polyester or elastane components
Elastic waistband may contain polyester or nylon, but antimony contamination is not a known issue in major textile manufacturers; no recalls or hazard reports specific to Lola.
The full breakdown
What it's made of and why it matters
Lola's period underwear uses organic cotton as its base fabric, which eliminates synthetic pesticide residues and heavy metal contamination common in conventional cotton. The water-resistant treatment is the critical component: Lola has certified this treatment PFAS-free, meaning they did not use legacy fluorochemical coatings (like those containing PFOA or PFOS) that persist in the body and environment. Third-party verification of the PFAS-free claim adds credibility. Organic cotton also reduces formaldehyde-based resin finishes often applied to conventional cotton for wrinkle-resistance or antimicrobial effects.
The brand's record and disclosure
Lola is known for transparency in material sourcing and has published certifications for GOTS (Global Organic Textile Standard) compliance on its cotton inputs. The brand explicitly markets PFAS-free construction as a selling point, suggesting deliberate avoidance rather than accidental compliance. No major safety recalls or contamination incidents are on record for Lola period underwear. The third-party verification of the PFAS-free water-resistant treatment distinguishes this product from many competitors who either use fluorochemical barriers or provide minimal disclosure.
How it compares in its category
Period underwear in general presents lower chemical exposure risk than disposable pads or tampons because of direct skin contact and zero internal placement. Lola's organic cotton plus certified PFAS-free water resistance positions it above mid-market brands that use conventional cotton or undisclosed water-resistant treatments. The category as a whole is safer than cosmetics or cookware in terms of systemic chemical hazard profile, provided the garment is laundered normally. Competitors vary widely: some offer organic cotton without waterproofing clarity, others use synthetic microfiber layers without PFAS disclosure.
If you buy it
Wash in warm water with gentle detergent before first wear to remove any manufacturing residues. Machine wash warm on gentle cycle; avoid bleach and fabric softener, which can degrade the water-resistant treatment and introduce unrelated chemicals. Dry on low heat or lay flat; high heat is not necessary and may accelerate wear. Replace when absorbency noticeably declines (typically 1-2 years with normal care) or if the elastic loses elasticity. Normal laundering does not require special precautions given the PFAS-free, organic base.
