What Comfort, Period. Women's Leaks 2-Pack is made of, ingredients and materials
This product is a cotton blend (percentage not specified in available product labeling) with an applied water-repellent and stain-resistant finish. The finish chemistry is not publicly disclosed by Hanes. Cotton itself is a natural fiber with low hazard profile, but the functional coating applied to achieve water and stain repellency is the primary safety consideration, as such finishes commonly contain PFAS or alternative chemicals whose long-term skin contact safety record may be incomplete.
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.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Undisclosed water-repellent and stain-resistant finish chemistry
Hanes has not disclosed the chemical composition of the applied finish. While such finishes may be safe, the lack of transparency on a product with prolonged intimate skin contact leaves uncertainty about the identity and long-term safety record of the coating.
Skin irritation from finish residue or degradation products
Repeated skin contact with an undisclosed finish in a warm, moist environment (menstruation) could theoretically cause irritation if the finish breaks down or if residual monomers are present. No specific cases linked to this product are documented, but the risk cannot be ruled out without chemical disclosure.
What’s reassuring
Formaldehyde / VOCs
No specific formaldehyde concern has been reported for Hanes period underwear. Cotton garments may use formaldehyde-containing resins in finishing, but published recalls or hazard notices specific to this product are not on record.
Source, ATSDR ↗Azo dyes and synthetic dye residues
No known issues with dyes in Hanes period underwear have been published. Azo dyes pose a hazard if they contain or break down into restricted amines; mass-market cotton underwear typically uses azo dyes, but restricted ones are largely phased out in US products.
Heavy metals
No published hazard or recall involving heavy metal contamination in Hanes period underwear or comparable Hanes intimate apparel is on record. Risk is low for finished cotton textiles sold in the US market.

The brand's record and disclosure
Hanes has not published detailed disclosure of the finish chemistry used on this product or broader commitment to PFAS-free formulations in intimate apparel. The brand has not sought third-party certification (such as OEKO-TEX or GOTS) that would typically require testing and transparency on restricted chemical use. Absence of disclosure on a product marketed for prolonged skin contact is a transparency gap, not proof of hazard, but it limits informed choice.
How it compares in its category
Period underwear products range widely in chemical transparency. Some competitors (e.g., Knix, Thinx) publish PFAS-free or low-PFAS claims with third-party testing; others, including many mass-market brands, do not. Hanes' silence on finish chemistry places this product in the lower-disclosure tier. Cotton-blend construction is standard and less of a concern than the applied coatings.
If you buy it
Wash separately from other garments in cool to warm water before first wear to reduce any loose finish residues. Launder frequently (after each wear) and avoid high heat drying, as repeated heat exposure may degrade the water-repellent coating and potentially alter its chemistry. Replace if the fabric loses water repellency or develops odor or discoloration despite regular washing. Do not bleach or use fabric softeners, which can strip or interact with the finish.
