What Always Infinity Size 5 Extra Heavy is made of, ingredients and materials
Always Infinity pads use layered non-woven synthetics (likely polypropylene and polyethylene) with an unspecified waterproof backing. Non-woven materials themselves carry low toxicity risk, but the waterproof treatment chemistry, critical for overnight protection, is not publicly disclosed. Without ingredient transparency, the specific coating (whether PFAS-based fluorochemicals, polyurethane, or silicone) cannot be 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.
PFAS
Waterproof treatment chemistry is not disclosed; PFAS is industry standard in menstrual-product backings. Brand PFAS safety score is 25/100, and no commitment to PFAS phase-out is published.
Source, ATSDR ↗Skin irritation or contact dermatitis from synthetic materials or residual coating
Non-woven synthetics and unspecified backing treatments can cause localized irritation in sensitive skin; no adverse-event data specific to this product is publicly available.
Microplastic shedding from non-woven degradation
Non-woven synthetics may fragment or shed particles over the pad's use or disposal lifespan; impact is localized to vaginal tissue and sewage rather than ingestion, but data on Always Infinity shedding rates is not public.
What’s reassuring
Formaldehyde / VOCs
Non-woven polypropylene fabrics may contain trace formaldehyde-based binders; no test results or warnings for Always Infinity are on record, and levels in menstrual pads are typically far below inhalation-exposure thresholds.
Source, ATSDR ↗Phthalates
Polypropylene and polyethylene do not require phthalates; no evidence of phthalate use in this product is documented. Risk is low unless unspecified additives are present in the backing treatment.
Source, ATSDR ↗The full breakdown
The brand's record and disclosure
Procter and Gamble (Always parent company) has not publicly committed to phasing out PFAS in period-care products or disclosed the waterproof treatment composition for Infinity pads. The brand maintains silence on chemical treatment details despite growing consumer and regulatory focus on PFAS in menstrual products. No major recalls or contamination findings are on record for this specific product line.
How it compares in its category
Most conventional period-pad brands use undisclosed waterproof treatments; Infinity is not unique in this opacity. Organic and eco-certified alternatives (such as Seventh Generation, Cora, or Thinx) more often disclose PFAS-free or minimal-chemical claims. Conventional overnight pads across the market (Kotex, Tampax, Kotex) share the same disclosure gap, making comparison difficult.
If you buy it
Store pads in a cool, dry place away from heat or direct sunlight to prevent any coating degradation. Replace pads if packaging is damaged or if backing shows visible wear or discoloration. Do not reuse or wash pads; they are single-use. If skin irritation develops, discontinue use and consider a brand with published chemical ingredient lists.
