Anigan · Period Underwear
PERIOD Women's Extra Coverage High Waisted Organic Cotton Period Underwear for Heavy Flow
Lower concern: organic cotton base with no known PFAS-prone coatings, but brand does not explicitly address PFAS.
This period underwear is made from organic cotton, a baseline safe material without Teflon-family coating coatings or water-repellent treatments typical of PFAS exposure. Anigan does not disclose PFAS testing or make PFAS-free claims.

Why this grade
Category baseline
period care is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
This product uses organic cotton for the outer layer and an absorbent core that is likely viscose or cellulose-based (common in period underwear for fluid retention). Organic cotton certification means no synthetic pesticide residues or heavy metal accumulation in the fiber itself. The absorbent core, if viscose-based, is chemically processed from wood pulp but the manufacturing process does not typically introduce persistent chemical hazards into the finished product. No waterproof coating is mentioned, suggesting the product relies on fabric density rather than Teflon-type coating or water-repellent chemical finishes.
The brand's record and disclosure
Anigan markets this product with emphasis on organic certification and does not currently publish independent third-party chemical testing results or explicit PFAS commitments on available marketing materials. The brand does not appear in major safety databases for documented chemical violations or recalls related to this product line. Organic Cotton Certified status (typically GOTS or equivalent) provides baseline assurance that input materials meet restricted-substance limits, though full supply-chain transparency on the absorbent core material is not publicly detailed.
How it compares in its category
Period underwear varies widely; some brands use waterproof synthetic linings or Teflon-type coating-based moisture barriers, both of which carry documented risks. Anigan's organic cotton approach aligns with the lower-chemical segment of the category. Competitors using conventional (non-organic) cotton or synthetic polymer linings may carry higher pesticide residue or PFAS exposure risk. No major independent testing has been published comparing Anigan to peers, so direct performance claims should be treated as marketing rather than verified equivalence.
If you buy it
Wash in cool to warm water before first use to reduce any residual dyes or processing agents. Machine wash in cold water with mild detergent; avoid bleach and fabric softener, which can degrade absorbency and introduce unnecessary chemicals. Do not use high-heat drying; air dry or low heat to preserve fabric integrity and prevent fiber degradation. Replace when absorbency noticeably declines or fabric shows thinning (typically 1-2 years with regular use); worn-out garments may shed microfibers.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Formaldehyde resins (finish treatments)
Organic cotton certification typically excludes formaldehyde-based wrinkle-resistant finishes. No formaldehyde-release hazard has been reported for this product or brand.
Azo dyes
Product color and dye composition not publicly disclosed. Organic certification does not explicitly exclude azo dyes, though many organic-focused brands source non-azo alternatives. Direct contact dyes pose minimal skin risk in finished textile but should be confirmed if sensitive-skin use is intended.
Antimony in polyester
This product is primarily organic cotton with cellulose-based absorbent core; no polyester content has been documented, eliminating antimony catalyst exposure.
Viscose/cellulose processing chemical residues
If the absorbent core uses viscose, sodium hydroxide and carbon disulfide are used in production but are typically removed during processing. Residual trace amounts are not documented as a hazard in finished consumer textiles at regulatory levels.
Microplastic shedding from degradation
Repeated washing and wear can cause cotton and cellulose fibers to break down and shed; this is not specific to Anigan but inherent to all synthetic-blend or durable absorbent garments. Shedding rate depends on fabric weave density and wash intensity.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
