What Seni Lady Maximum is made of, ingredients and materials
Seni Lady Maximum uses an absorbent core (likely cellulose and superabsorbent polymers) paired with a waterproof backing layer; the backing chemistry is the critical unknown. Waterproof layers in period products typically use either polyethylene (low risk) or fluorochemical coatings for enhanced repellency, and Seni has not disclosed which. The core materials themselves are standard for the category, but the backing determines whether PFAS or other leachables contact skin during extended wear.
What’s concerning
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 treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Seni does not disclose the chemistry of its waterproof backing. If fluorochemical-based (rather than polyethylene), potential for skin contact with volatile or leachable compounds; specific risk cannot be quantified without disclosure.
Source, ATSDR ↗Skin irritation and contact sensitization from backing materials
High-absorbency pads with waterproof backings can trap moisture and heat if changed infrequently, increasing risk of irritation independent of chemical toxicity. Seni's backing material identity is unknown, so comparison to safer alternatives (e.g., breathable, chlorine-free options) is not feasible.
Disposal and environmental persistence
If the waterproof backing contains PFAS or other persistent polymers, disposal in household waste contributes to landfill and potential groundwater contamination; Seni provides no guidance on environmental impact of its waterproofing method.
What’s reassuring
Superabsorbent polymer (SAP) integrity and leaching
Sodium polyacrylate, standard in period pads, is generally recognized as safe at skin-contact levels, but degradation over time or exposure to heat may alter particle size. No recalls or widespread complaints specific to Seni Lady Maximum have been documented.
Adhesive and elastic component chemicals
Period pads use adhesives and elastic components that may contain plasticizers or residual solvents. Seni does not publish safety data on these, and no independent analysis of Seni Lady Maximum adhesives has been published.
How is this PFAS grade calculated?
The brand's record and disclosure
Seni is a German-owned brand (now part of Essity, a major hygiene company) with established presence in European markets, but has published no independent certifications (such as Oeko-Tex or similar) regarding chemical content or waterproofing methods. The brand has remained silent on PFAS despite industry-wide questions about menstrual product safety, particularly following 2021-2023 media scrutiny of 'forever chemicals' in period products. This silence is not evidence of use, but absence of transparency in a category where competitors have begun disclosure.
How it compares in its category
Seni Lady Maximum occupies the mid-to-premium segment for incontinence-style period protection (high-absorbency pads). Competitors like Kotex and Always have begun voluntary PFAS or chemical disclosures under consumer pressure; Seni's lack of public statements places it below these leaders on transparency, though this does not confirm higher chemical risk. No independent lab testing of Seni Lady Maximum for PFAS or phthalates has been published in accessible sources.
If you buy it
Change pads every 4-6 hours to minimize prolonged skin contact with any potential leachables from the backing layer. Store in a cool, dry place away from direct heat or sunlight, as warmth can accelerate breakdown of polymer layers. Do not flush; dispose in household waste. If you experience unexplained skin irritation, sensitivity, or allergic reactions, discontinue use and consider testing with a product that has published chemical disclosures. Request Seni's waterproofing method and material safety data by contacting customer service; brand responsiveness to transparency requests influences future purchase decisions.
