Lola Bikini Period Underwear

Good

A water-repellent or grease-resistant treatment of unstated chemistry, with a brand PFAS statement we have not verified.

Verdict · SkipOrganic cotton base is lower-risk; water-resistant finish chemistry unverified despite PFAS-free claim. Use cautiously pending disclosure.

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.

Brand says: “LOLA says its period underwear and pads are made without PFAS.”

What Lola Bikini Period Underwear is made of, ingredients and materials

Lola period underwear uses organic cotton as the primary material, which avoids synthetic polymer risks like BPA and phthalates common in conventional polyester blends. The water-resistant finish applied to the gusset or absorbent layer is the critical unknown, the brand claims PFAS-free treatment, but the specific chemistry (whether silicone-based, paraffin wax, or another water-repellent coating) is not publicly disclosed. Organic cotton itself is lower-pesticide-risk than conventional cotton, and cotton does not leach hazardous monomers when wet or worn at body temperature.

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.

75/ 100
⚠️

Water-repellent finish chemistry (unspecified)

The brand claims PFAS-free but does not publicly disclose the specific treatment chemistry (silicone, wax, polyurethane, etc.). Without independent test results or third-party certification, the actual composition and long-term stability of the finish cannot be independently confirmed.

70/ 100
🫧

Coating degradation and microparticle release

All water-repellent finishes degrade with washing and wear. If Lola's finish is not durable or releases particles as it wears, users could be exposed to microparticles from the finish material. Product longevity and finish durability are not specified in available information.

70/ 100
🏷️

Allergic contact dermatitis from undisclosed additives

Organic cotton reduces pesticide residue risk, but the proprietary water-repellent finish may contain additives, catalysts, or residual reactants not listed. Individuals with sensitive skin should test cautiously, as the finish chemistry is not fully transparent.

70/ 100

What’s reassuring

✅

Brand-stated PFAS-free

The brand states this product is PFAS-free. We have not verified the claim.

100/ 100
💨

Formaldehyde / VOCs

No formaldehyde-based resin finishes are reported on this product. Organic cotton base and PFAS-free claim suggest avoidance of legacy durable-press treatments, but absence of published test results means this cannot be fully ruled out without disclosure.

How is this PFAS grade calculated?

The brand's record and disclosure

Lola has made a public PFAS-free claim but has not independently verified this statement with third-party testing results or certification (such as OEKO-TEX or Bluesign) that are publicly available. The brand markets itself as transparent on materials, yet the water-repellent treatment remains proprietary and undisclosed in detail. No established recalls or safety controversies specific to Lola period underwear are on record. Without published test reports or certification, the claim rests on company assertion rather than external verification.

How it compares in its category

Period underwear as a category often uses synthetic-blend fabrics (polyester, nylon) with water-repellent coating finishes that historically contained Teflon-type coating or other regulated or restricted compounds. Lola's organic cotton approach is less common and potentially lower-risk if the finish is genuinely PFAS-free and stable. However, most mainstream period underwear brands (Thinx, Knix, Aisle) have independently tested and published PFAS results or hold third-party certifications, which Lola has not yet demonstrated at the public level.

If you buy it

Wash in warm water (not hot) and avoid high heat in the dryer, as repeated heat exposure may degrade or shift the water-resistant finish over time. Inspect the absorbent layer monthly for degradation, pilling, or reduced water resistance, which may signal that the treatment is wearing out. Avoid prolonged contact with bleach or fabric softeners, which can strip or alter water-repellent coatings. Replace the product if the gusset loses water resistance or if any odor, discoloration, or material breakdown develops, as these indicate the finish or fiber integrity has failed.
