The Lola High Waist Period Underwear
A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.
LOLA says its period underwear and pads are made without PFAS. We record that as an unverified brand claim. Its record describes a water-repellent or grease-resistant treatment of unstated chemistry, which is still counted.

What The Lola High Waist Period Underwear is made of, ingredients and materials
Lola's period underwear uses organic cotton as the primary fabric, which avoids pesticide residues and synthetic fiber shedding common in conventional cotton. The product incorporates a water-resistant treatment applied to the gusset or absorbent layers, but the chemical composition of this treatment is not disclosed in available product information. Organic cotton itself is free of inherent hazards like azo dyes or formaldehyde finishes typical of mass-market textiles, but the efficacy and safety profile of the water-repellent coating cannot be assessed without ingredient transparency.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Undisclosed water-repellent treatment chemistry
The brand claims PFAS-free status but does not publicly name the water-resistant coating (e.g., water-repellent coating, wax-based, or alternative polymer). Without independent verification or ingredient transparency, the actual chemical nature and long-term safety of this treatment cannot be confirmed.
Skin irritation or allergic reaction to treatment
Period underwear sits against sensitive skin for extended periods. An unknown water-resistant coating could irritate or trigger contact dermatitis in susceptible individuals, particularly if the chemical is not widely tested or if residual monomers remain from manufacturing.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Formaldehyde / VOCs
Organic cotton in this product is unlikely to carry formaldehyde-based finishing resins used in conventional textiles, and no reports of formaldehyde issues in Lola products are on record. However, the undisclosed water-resistant treatment could theoretically include formaldehyde-releasing components, which is not ruled out.
Source, ATSDR ↗Heavy metals
Organic cotton textiles are typically produced with strict dye standards to maintain organic certification. No reported cases of azo dye or heavy metal contamination in Lola period underwear are on record, and the organic certification process generally excludes these hazards.
Source, FDA ↗Microplastic shedding from synthetic fibers
Organic cotton construction minimizes microplastic release compared to polyester-heavy period underwear. However, if the water-resistant treatment is a synthetic polymer, minor shedding is theoretically possible but has not been reported for this product.
How is this PFAS grade calculated?
The brand's record and disclosure
Lola makes a public claim of being PFAS-free but has not provided third-party certification or detailed chemical composition for the water-resistant treatment. The brand markets toward health-conscious and environmentally aware consumers, positioning itself as having lower concern than conventional period products, yet material safety disclosures remain limited. No established recalls or safety controversies for this specific product are on record. Their PFAS stance appears to be a marketing assertion rather than a verified standard (such as OEKO-TEX or bluesign), leaving the actual treatment chemistry unconfirmed.
How it compares in its category
Period underwear as a category typically relies on polyester, nylon, or cotton blends with synthetic water-repellent finishes; Lola's organic cotton choice reduces exposure to synthetic microfibers and conventional pesticides. Most competitors in the direct-to-consumer period underwear space (Knix, Thinx, Aisle) also claim low-chemical or PFAS-free positioning but similarly withhold detailed treatment chemistry. Lola's transparency lags behind brands offering OEKO-TEX certification or full chemical disclosure, making side-by-side safety assessment difficult. The organic cotton base is a genuine advantage over polyester-dominant alternatives, provided the water-resistant treatment does not offset that benefit.
If you buy it
Wash in cool to warm water and dry on low heat or air-dry to preserve the water-resistant coating and prevent any unknown treatment compounds from degrading or releasing at high temperatures. Replace the underwear if the water-resistant layer begins to break down (signs include increased liquid seepage despite prior performance) or if any skin irritation develops, as a compromised coating may expose the organic cotton backing unevenly. Store in a cool, dry place and avoid prolonged exposure to direct sunlight, which can degrade synthetic treatments over time. Contact the brand if irritation occurs to determine whether the issue is cotton-related or linked to the treatment.
