What Always Infinity Overnight Long Menstrual is made of, ingredients and materials
Always Infinity Overnight pads use nonwoven synthetic layers (polyethylene or polypropylene) with an unspecified water-resistant or waterproof back coating. The brand does not publicly identify the chemistry of that coating, which is the primary concern for PFAS contamination in absorbent menstrual products. Nonwoven synthetics themselves do not pose recognized leaching risks under normal use; the hazard lies in the waterproofing layer's composition and any migration to skin or into the bloodstream during extended wear.
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
The brand does not name or test the waterproofing agent. PFAS is commonly used in menstrual-pad backings to repel liquid; lack of disclosure is a red flag but not proof of presence.
Source, ATSDR ↗Microplastics
Overnight pads are worn 8+ hours continuously. Nonwoven synthetics and unspecified coating polymers can fragment or leach if stressed or degraded; no product-specific testing is publicly available.
Source, EPA ↗Dermal sensitization or allergic reaction to coating additives
Some users report skin irritation or allergic contact dermatitis with conventional menstrual pads; triggers are often undisclosed adhesives, fragrances, or coating residues. Always Infinity is unscented but coating composition remains opaque.
What’s reassuring
Phthalates
No phthalates or plasticizers have been reported in Always Infinity pads. Nonwoven synthetics (PE/PP) typically do not require phthalates, but unspecified adhesives or coating components are not ruled out.
Source, ATSDR ↗Heavy metals
No contamination with heavy metals or azo dyes has been documented for this product. Synthetic nonwovens used in menstrual pads do not typically incorporate pigments, but certification would confirm.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Always (Procter and Gamble subsidiary) has not publicly disclosed materials testing data, PFAS presence or absence, or waterproofing chemistry for this product line. The brand has not pursued third-party certification bodies such as Cradle to Cradle, GOTS, or similar standards that would require ingredient transparency. No recalls or regulatory actions specific to this pad have been recorded in FDA or consumer safety databases. The silence on waterproofing agents, especially for an overnight product designed for prolonged skin contact, represents a significant transparency gap in a product category increasingly scrutinized for PFAS.
How it compares in its category
Always Infinity Overnight competes with brands such as Kotex, Tampax, and private-label pads, most of which also do not disclose waterproofing chemistry. Some smaller brands (e.g., Aisle, Rael, Cora) have begun offering PFAS-free or certified products with transparent material lists. In absorbency and performance, Always Infinity is a mainstream mid-to-premium offering. From a hazard-disclosure standpoint, it falls below emerging market leaders but is typical of legacy menstrual-product brands.
If you buy it
Change pads every 4-8 hours as directed to minimize skin contact time, particularly important given the unverified coating chemistry. Store in a cool, dry place away from direct heat or moisture that could degrade the nonwoven base. Do not reuse or wash pads. If you experience skin irritation, rash, or allergic response during use, discontinue and consult a healthcare provider, as this may signal sensitivity to coating additives or degradation byproducts.
