LOLA Washable 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 LOLA Washable Period Underwear is made of, ingredients and materials
LOLA period underwear is a cotton blend with an unnamed water-resistant treatment applied to create its moisture-barrier function. The cotton base itself is a natural fiber with low inherent toxicity risk, but cotton production can involve pesticide residues if not organically grown, and the water-resistant finish is where chemical hazard concentrates. The specific chemistry of this treatment is not disclosed publicly, which limits independent assessment of what substances are used.
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.
Water-resistant coating chemistry (unspecified)
The treatment used to achieve water resistance is not publicly disclosed. While LOLA claims PFAS-free status, the actual chemistry of the substitute treatment is unknown, leaving a data gap on potential alternatives (e.g., silicone-based, polyurethane-based, or other durable water repellents).
Pesticide residue
LOLA does not specify whether the cotton blend is organically grown or conventionally sourced. Conventional cotton can carry pesticide residues; public information does not confirm organic certification for this product.
Source, EPA ↗Synthetic fiber blend degradation
Cotton blends often include polyester or elastane for stretch and durability. Polyester can shed microfibers with washing, and elastane can degrade with heat and friction. No accelerated wear or microfiber shedding data is available for this specific product.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Contact allergy to coating or dyes
No documented cases of allergic reactions to LOLA period underwear have been published. However, the unspecified water-resistant treatment and lack of full ingredient disclosure mean individual sensitization risk cannot be ruled out.
Heavy metals
No testing or recalls for lead, cadmium, or other heavy metals in LOLA period underwear colorants have been reported. Cotton-based textiles are not a primary route for heavy metal exposure, but third-party dye testing is not publicly available for this brand.

The brand's record and disclosure
LOLA has made a public claim to be PFAS-free, but this statement has not been independently verified by third-party testing or published test reports available in the public domain. The brand does not appear to hold major textile certifications (such as OEKO-TEX or Bluesign) that would provide transparent chemical inventories. No recalls or safety controversies specific to LOLA period underwear have been documented in public safety databases.
How it compares in its category
Period underwear as a category typically relies on water-resistant coatings or laminated layers; LOLA's approach is mid-market in terms of transparency. Some competing brands (e.g., Knix, Thinx) have published more detailed material specs or pursued third-party certifications. LOLA's lack of disclosed certifications or detailed chemical transparency is relatively common in the direct-to-consumer period-apparel space but lags brands with OEKO-TEX or similar accreditation.
If you buy it
Wash in cool to warm water and air-dry to preserve the water-resistant coating; high heat (dryer) can degrade synthetic treatments over time. Replace the product if the absorbent or water-resistant properties noticeably decline, typically after 1 to 2 years of regular use. Avoid prolonged contact with strong detergents or bleach, which may compromise the treatment. Monitor for any skin irritation; if rashes develop, discontinue and consider that contact allergy to the unnamed coating is possible, though uncommon.
