Organic Cotton Period Underwear
Lower concern. Organic cotton core, no water-resistant treatment disclosed.
Lola's organic cotton period underwear uses inherently PFAS-lower-risk materials. Brand does not disclose water-repellent coating treatments or provide third-party testing.

What’s concerning
Category baseline
period care is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Formaldehyde / VOCs
Organic cotton still undergoes dye and finishing processes that may include formaldehyde-releasing resins for wrinkle resistance or water repellency in the non-coated gusseted layer. Lola does not disclose finishing chemistry; GOTS certification (if present) limits but does not eliminate this risk. Pre-wash mitigates exposure.
Source: ATSDR ↗Azo dyes and color fastness
The colored gusseted or trim areas may use azo dyes, which are regulated but can release aromatic amines under certain conditions (prolonged moisture, sweat). Organic certification may reduce but does not guarantee avoidance. No third-party dye safety data available for Lola specifically.
Microplastic shedding
If the gusseted layer contains polyester microfibers, repeated washing may release synthetic microplastics into wastewater. Organic cotton itself does not shed microplastics; the undisclosed absorbent layer material determines actual risk level.
What’s reassuring
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Gusseted layer composition and leachables
The absorbent core material (likely polyester, cellulose, or synthetic blend) is not disclosed. No established leaching or toxicity issues are on record for standard absorbent textiles in period products, but lack of transparency prevents full assessment.
Talc contamination
No evidence that Lola period underwear contains talc; this hazard is not typically associated with textile-based period products and is more relevant to powder or insertable products.
The full breakdown
What it's made of and why it matters
Lola period underwear uses certified organic cotton as the primary material, which avoids synthetic pesticide residues and reduces chemical processing typical of conventional cotton. The gusseted absorbent layer composition (polyester blend or cellulose-based materials) is not fully disclosed by the brand, which is common in this category. Organic cotton itself does not require Teflon-type coating water-resistant coatings, lowering fluorochemical exposure compared to leak-proof alternatives.
The brand's record and disclosure
Lola has not published detailed chemical disclosure statements or third-party safety test results for its period products. The brand markets organic cotton as a differentiator but remains silent on gusseted layer composition, dyes, and processing chemicals beyond organic claims. No recalls or regulatory safety violations are on public record for Lola period underwear. Standard claims of GOTS or similar textile certification would indicate dye and finish safety oversight, though specific certifications should be verified on product packaging.
How it compares in its category
Organic cotton period underwear sits in the mid-to-premium segment, offering lower chemical load than bleached conventional cotton but with less transparency than some competitors (e.g., Thinx, Knix) that publish component certifications. The lack of water-resistant coating reduces PFAS risk versus some reusable absorbent period products. Trade-off is less detailed ingredient disclosure compared to leading brands, though safety profile appears standard for the category.
If you buy it
Wash in cool water before first use to remove any residual processing chemicals. Machine wash separately on gentle cycle with mild detergent; avoid fabric softeners and bleach, which can degrade both organic cotton and absorbent layers and introduce unnecessary chemicals. Air dry to extend product life and prevent heat degradation of synthetic components in the gusseted layer. Replace every 1-2 years or when absorbency noticeably declines. No heat exposure (dryer, ironing) is necessary and may reduce longevity.
