No Boundaries Boyshort Super Absorbency Period Underwear, 2-Pack, Womens Sizes Xs-xxl, Women's, Size: Small, Beige
Skip until brand discloses coating chemistry and PFAS status.
Period underwear with super-absorbency features typically require water-repellent finishes, often PFAS-based. Brand provides no coating details or PFAS information, creating significant uncertainty.

What No Boundaries Boyshort Super Absorbency is made of, ingredients and materials
This product is a cotton-blend fabric with an applied waterproof or stain-resistant coating whose chemistry is not publicly specified by the brand. The coating is the critical unknown, waterproof layers on textiles are often applied using PFAS compounds (PFAS "forever chemicals") to achieve water repellency, though other chemistries exist. Cotton itself is a low-concern natural fiber, but the coating's identity and durability determine whether leaching or off-gassing becomes a practical risk during wear and washing.
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.
Waterproof/stain-resistant coating chemistry (unspecified)
The product's waterproof layer is not chemically identified in marketing materials. While likely PFAS-based (common industry practice), other fluorine-free or PFAS-alternative coatings are possible but unconfirmed. The risk level depends on coating identity and durability, both unknown.
Coating degradation and leaching over time
Waterproof coatings on textiles degrade with repeated washing and wear. If the coating contains PFAS or other leachable compounds, degradation may release them into wash water or against skin over the product's lifetime. This risk is proportional to coating durability and chemical composition, both unspecified.
What’s reassuring
Formaldehyde / VOCs
No public record of formaldehyde-based finishes or wrinkle-resistant treatments on this specific product. Cotton-blend period underwear typically does not require heavy formaldehyde finishing, but lack of Oeko-Tex or similar certification leaves this unverified.
Source, ATSDR ↗Azo dyes or restricted colorants
The beige color of this product does not inherently indicate use of carcinogenic azo dyes, but the brand provides no dye safety certification. Beige and neutral tones are typically lower-risk than deep colors, but assurance is absent.
Skin contact sensitization from undisclosed additives
No documented allergic reactions or contact dermatitis reports for this specific product. However, the unspecified coating and any embedded antimicrobial or anti-microbial agents increase uncertainty for users with sensitive skin or fragrance sensitivities.
The full breakdown
The brand's record and disclosure
No Boundaries (a Walmart house brand) has not publicly disclosed the chemical composition of the waterproof treatment on this or similar products, nor has it issued a PFAS policy or third-party safety certifications for period underwear. The brand's silence on coating chemistry is a red flag for informed purchasing, as major competitors in period-care (Thinx, Knix) have begun transparency efforts. No recalls or established safety controversies specific to this SKU are on record.
How it compares in its category
Period underwear is a fast-growing category where coating chemistry is central to safety assessment. Products certified by Oeko-Tex or bearing PFAS-free claims (e.g., some Thinx or Knix variants) offer greater transparency than this unspecified No Boundaries version. At its price point, No Boundaries competes on affordability, not disclosure, making it a budget option with higher uncertainty about the waterproof layer's long-term safety profile.
If you buy it
Wash in cold water and avoid high heat (dryer) to minimize any potential leaching or breakdown of the coating. Replace every 6-12 months or when absorbency declines, as coatings degrade with repeated washing. Hand-washing may extend the coating's integrity compared to machine washing. If you or anyone wearing these items has skin sensitivity or concerns about PFAS exposure, request the coating material safety data sheet from No Boundaries customer service before purchase; silence on this question is a reason to choose a competitor with published disclosure.
