Always Ultra Thin Super Pads

Poor

Period pads need water-repellency; Always discloses nothing about PFAS treatment.

Verdict: SkipPFAS concerns plus undisclosed water-resistant chemistry warrant informed use; no established non-PFAS hazards identified, but transparency gap exists.

Water-resistant technology prevents leakage but Always doesn't disclose coating agents or PFAS status. Seek brands with explicit PFAS-free claims.

What’s concerning

♾️

Waterproof / stain-resistant treatment

Water-repellent treatments have historically contained PFAS chemicals.

65/ 100
♾️

Category baseline

PFAS exposure happens more often with clothing products.

75/ 100
♾️

No PFAS disclosure

The company has not publicly discussed PFAS in this product.

85/ 100
🏷️

PFAS

PFAS contamination has been documented in menstrual pads by independent testing (MIT study, 2021; various advocacy reports). Always does not publicly confirm or deny PFAS use in water-resistant topsheet; graded poor (25/100) on available evidence, creating a high uncertainty rather than proven presence.

⚠️

Skin sensitization or allergic contact dermatitis

No specific allergic incidents tied to Always Ultra pads are established in public records. However, undisclosed adhesives, dyes, or coating residues in synthetic layers could theoretically trigger reactions in sensitive individuals, though this is uncommon and not product-specific.

70/ 100
🎨

Fragrance or dye reactions

Always Ultra Thin scented variants (some regional versions) use fragrance additives. Unscented versions avoid this. Fragrance components are not itemized, so risk of sensitization exists for fragrance-sensitive users, though incidence is not elevated versus competitors.

70/ 100

What’s reassuring

Microplastic or polymer shedding

No documented evidence that Always pads shed microplastics or polymer fragments during normal use. The polypropylene layers are bonded in manufacture; degradation under body temperature and moisture is theoretically minimal but has not been independently tested for this brand.

95/ 100

Chlorine or bleach residue (from manufacturing)

Cellulose pulp in sanitary products is typically bleached during pulping. Always does not disclose bleach type or residual levels. Elemental chlorine-free (ECF) or totally chlorine-free (TCF) processes reduce residue, but no public statement from the brand confirms their method.

95/ 100

The full breakdown

What it's made of and why it matters

Always Ultra Thin Super uses a core of cellulose (wood pulp) layered with synthetic polymers (likely polypropylene) and an undisclosed water-resistant topsheet treatment. That water-repellent layer is the functional requirement for absorption control, but Always does not publicly specify whether it contains PFAS, fluorocarbon coatings, or silicone-based alternatives. The cellulose itself is generally safe; the concern centers on the treatment chemistry and any migration of additives into prolonged skin contact.

The brand's record and disclosure

Procter and Gamble (Always parent company) has not published ingredient transparency reports specific to period pad coatings or disclosed PFAS use in this product line. The company has faced criticism from menstrual product advocacy groups for lack of ingredient labeling compared to some competitors. No recalls or established safety incidents are on record for Always pads, but the absence of disclosure makes independent verification difficult.

How it compares in its category

Most mass-market pads (Kotex, Tampax, store brands) use similar synthetic-cellulose composites with undisclosed water treatments; disclosure across the category is poor. Some smaller brands (Seventh Generation, Cora, Rael) now explicitly avoid PFAS and fluorochemicals, though they command higher prices. Always remains in the mainstream tier with minimal ingredient communication, neither distinctly worse nor better than major competitors on this metric alone.

If you buy it

Change pads every 4-8 hours to minimize prolonged skin contact and reduce any chemical exposure. Store in a cool, dry place away from direct heat or humidity, which could theoretically increase leaching (though no data confirms this risk for pads). If you experience unexplained skin irritation or sensitivity after switching products, consider rotating to a brand with published PFAS-free claims. Monitor public health updates on PFAS in menstrual products, as regulation and testing in this category remain limited.
