LOLA Washable Period Underwear
Brand claims PFAS-free; no independent verification available
LOLA explicitly states their period underwear contains no PFAS. Cotton-based materials with moisture-wicking treatment lower inherent risk, though independent lab verification is absent.
Brand says: “LOLA period underwear is made without PFAS”

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 composition (unverified)
Brand claims PFAS-free treatment but has not published third-party verification or disclosed the specific chemistry. Without independent testing, the actual water-repellent coating agent (fluorine-based, silicone-based, or other) cannot be confirmed.
Coating degradation and microfiber shedding
Washable period underwear durability varies; repeated laundering can degrade water-resistant coatings, potentially releasing microfibers. No product-specific data exists for LOLA, but this is an inherent risk in any treated textile product.
Skin irritation from coating or dyes
Cotton-blend base is generally low-risk for irritation, but the water-resistant coating may contact sensitive skin. No widespread complaints are documented, but individual sensitivities to polyurethane or other coating polymers are possible.
What’s reassuring
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Formaldehyde / VOCs
No reports of formaldehyde-releasing finishes in LOLA products; cotton-blend construction and brand positioning suggest low likelihood, but material specifications are not publicly detailed.
Source: ATSDR ↗Heavy metals
No recalls or test data indicate azo dyes or heavy-metal contamination in LOLA period underwear. Cotton-dominant composition reduces risk compared to synthetic dye-heavy textiles.

What it's made of and why it matters
LOLA period underwear is constructed from a cotton blend with a water-resistant treatment applied to the gusset area. The cotton component is breathable and reduces skin irritation risk compared to synthetic-only alternatives. The water-resistant coating is the critical variable: if it relies on traditional durable water repellents (water-repellent coating), it likely contains PFAS or Teflon-family coating, which the brand claims are absent but has not independently verified. The durability of this coating over repeated wash cycles directly affects both product performance and the potential for coating degradation to shed microfibers.
The brand's record and disclosure
Lola markets itself as a 'clean' period-care brand with a public PFAS-free claim, but no third-party certification (like STANDARD 100 by OEKO-TEX or similar) has been independently published for this product. The brand has not disclosed the specific water-resistant chemistry used, which is a transparency gap. No major recalls or safety controversies are on record for Lola period underwear. Their general positioning emphasizes ingredient disclosure, though chemical specificity on coatings remains limited in publicly available materials.
How it compares in its category
Washable period underwear market participants vary widely in coating transparency. Competitors such as Thinx and Knix also use water-resistant treatments with similar disclosure gaps. Traditional disposable pads and tampons carry different chemical profiles (rayon, adhesives, fragrance risks) rather than coating hazards. Compared to absorbent-only cotton or organic cotton underwear, any water-resistant finish introduces an additional chemical variable. LOLA's cotton-blend approach is mainstream for this product category and generally poses lower microfiber risk than fully synthetic bases.
If you buy it
Wash in cold water and avoid high heat drying, which can degrade the water-resistant coating and increase shedding. Replace when the gusset coating shows visible wear (peeling, cracking, or loss of water repellency), typically after 1-2 years of regular use. Do not bleach or use fabric softeners, which compromise water-repellent coating durability. If you have sensitive skin, test a single pair first; while cotton-blend is generally low-risk, the coating itself may trigger reactions in a small subset of users.
