What Saalt Leakproof Teen Period Full Coverage is made of, ingredients and materials
Saalt Teen Period Underwear is described as a cotton blend with an unspecified waterproof and absorbent coating. The cotton portion is generally low-risk for chemical hazards, but the coating formulation is the critical unknown, it is responsible for waterproofing and absorbency, and no public disclosure confirms whether it contains PFAS-free alternatives or legacy PFAS chemistry. Without coating chemistry transparency, the safety profile of the absorbent layer cannot be fully assessed.
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 coating leachates (undisclosed chemistry)
The brand has not disclosed whether the waterproof coating contains PFAS, Teflon-family coating, or alternative chemistries. Any coating applied to textiles that contact skin can leach into sweat or moisture; without chemistry disclosure, risk level cannot be ranked as none_known, but also cannot be confirmed as present.
Coating degradation and skin irritation
Over time and with repeated laundering, waterproof coatings can crack, peel, or lose integrity. Degraded coatings may increase direct skin contact with the absorbent layer underneath and release particles or residual coating chemicals. No specific complaints are documented, but this is a predictable aging pathway for all coated textiles.
What’s reassuring
Formaldehyde / VOCs
No public disclosure or recall suggests formaldehyde-based finishes in this product line. Standard cotton blends may use formaldehyde-free binders, but Saalt has not specified this for Teen Period Underwear.
Source, ATSDR ↗Azo dyes in textile coloring
No restrictions or warnings specific to this product have been identified. If the underwear is dyed black or dark colors, azo dyes may be present; no evidence of banned azo compounds is on record, but the brand does not confirm testing for restricted azo metabolites.
Antimony in polyester component
If polyester is part of the cotton blend, antimony oxide catalyst residue is a known concern in the industry, but no product-specific data or warnings for Saalt Teen Period Underwear exist on record.
How is this PFAS grade calculated?
The brand's record and disclosure
Saalt has not publicly disclosed the chemical composition of the waterproof coating used in this product, nor has the brand issued a statement on PFAS avoidance or third-party testing results. No recalls, safety alerts, or documented controversies specific to this product line are on record. The absence of disclosure is a transparency gap rather than evidence of contamination, but it prevents independent verification of the coating's safety claims.
How it compares in its category
Period underwear is a category where waterproof coatings are essential but often rely on PFAS or alternative chemistries that brands rarely disclose. Competitors including Knix, Thinx, and Proof have faced consumer scrutiny over PFAS in coatings; some have moved toward PFAS-free options but rarely detail the replacement chemistry. Saalt's silence on this point is not uncommon in the category, but it is also not a differentiator in favor of this product.
If you buy it
Wash before first use and after each wear in cold water with mild detergent to reduce any residual coating leachates. Avoid bleach, fabric softeners, and high-heat drying, which can degrade the waterproof coating and potentially increase migration of coating chemicals during laundering. Replace the underwear if the waterproof layer visibly degrades, develops odor, or loses absorbency, as coating breakdown may increase skin contact with base materials. Request the brand to disclose coating chemistry; consumer demand for transparency is the most direct lever for category-wide improvement.
