Anigan · Period Underwear
Organic Cotton and Hemp fiber Leakproof Period Undies – no PFA added - Rif Care Medium $29 / 4 packs
Lower-concern choice with explicit PFAS claim, but lack of third-party verification leaves some uncertainty about leak barrier.
Anigan explicitly claims 'no PFA added' on the packaging, which is a positive signal for this period-underwear product. Organic cotton and hemp are inherently lower-risk materials.

Why this grade
Category baseline
period care is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
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 combines organic cotton and hemp fiber, both naturally absorbent plant-based materials, with an unspecified leak-resistant layer. Organic cotton eliminates synthetic pesticide residues common in conventional cotton. Hemp fiber is durable and antimicrobial by nature. The leak barrier composition is not disclosed, which is the main uncertainty: it may use polyester, nylon, or TPU (thermoplastic polyurethane), each with different durability and chemical profiles.
The brand's record and disclosure
Anigan explicitly markets this product as PFAS-free, addressing the primary chemical concern in moisture-barrier underwear. However, the company does not appear to have third-party certifications (e.g., GOTS for organic fiber, or independent leak-barrier testing) published in standard databases. No recalls, manufacturing controversies, or chemical violations are on record for this brand. The lack of transparency on the leak-layer material itself is a gap in full disclosure.
How it compares in its category
Period underwear typically relies on synthetic leak barriers that may contain PFAS, phthalates, or other chemical dyes. Anigan's explicit PFAS-free positioning is a competitive advantage. Organic cotton base is comparable to higher-end period underwear brands (Thinx, Knix). The mid-range price point and 4-pack format suggest materials and durability are standard for the category, not premium.
If you buy it
Wash in cool or warm water with mild detergent; avoid bleach and fabric softeners, which degrade elasticity and absorbency. Line-dry or tumble on low heat to extend leak-barrier life. Replace when absorbency noticeably declines (typically 1-2 years with regular use) or when elastic loses tension. Do not expose to prolonged heat or chlorinated pools, which can degrade synthetic components in the barrier layer.
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 in textile finishing
Organic cotton is typically processed without formaldehyde-based dyes or cross-linking resins. No published reports of formaldehyde in Anigan products or in certified organic cotton underwear. Standard commercial organic textile finishing avoids these chemicals.
Azo dyes (carcinogenic dye precursors)
Organic cotton products are generally dyed with fiber-reactive or natural dyes rather than azo dyes. No documented azo dye concerns in Anigan products. Color additives in organic textiles are not regulated differently, but low-chemical-processing standards in organic supply chains reduce risk.
Heavy metals in pigments and dyes
Any colored textile may contain trace heavy metals (cadmium, lead) in pigments. The product photo suggests dark color; Anigan has not disclosed third-party heavy-metal testing. Risk is low for period underwear (brief skin contact, non-mouth contact), but dermal absorption over months is not quantified.
Undisclosed synthetic barrier material leachables
The leak-resistant layer material is not identified on the product description. If it is polyurethane or polyester, degradation over time or with heat/detergent can release oligomers or softeners. Without material specification, long-term safety cannot be fully assessed.
Phthalates in elastics or synthetic components
Organic cotton garments typically use phthalate-free elastics (modern standard). No recalls or reports of phthalate contamination in Anigan products. Hemp and organic cotton bases do not inherently contain phthalates; risk would arise only from the unnamed barrier layer.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
