Always Extra Heavy Overnight Maxi Pads
Waterproof coating unspecified; PFAS risk unclear without transparency.
Always does not disclose PFAS status or waterproofing chemicals. Menstrual pads commonly use water-repellent coating treatments that may contain PFAS, but no lab data confirms presence in this product. Request detailed ingredient transparency from brand.

What’s concerning
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
period care is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Waterproof coating composition (unspecified)
The plastic backing's waterproof coating is not disclosed by Always; it may contain Teflon-type coating, polyurethane, or other compounds that could shed or leach under prolonged skin contact and moisture exposure. Without transparency, risk cannot be quantified.
Microfiber and plastic backing degradation
Menstrual pads shed microfibers from the plastic backing, particularly during use and storage. Long-term health effects of microfiber ingestion or inhalation remain under study, but the physical shedding is documented in product integrity assessments.
Adhesive leachables
The adhesives binding the pad layers may contain unreacted monomers or plasticizers that can migrate into skin under warm, moist conditions. Composition is not publicly disclosed for this product.
Contact dermatitis from undisclosed additives
Always Extra Heavy does not disclose whether the cellulose or plastic layers contain dyes, fragrances, antimicrobials, or antistatic agents. Individual sensitivity to these additives is common in menstrual product users, and lack of disclosure prevents pre-purchase assessment.
Skin irritation from prolonged moisture barrier contact
The plastic backing creates an occlusive environment against skin, which can trap moisture and heat and promote bacterial growth and maceration. This is not unique to Always but is exacerbated by the overnight-use duration and thickness of this product.
The full breakdown
What it's made of and why it matters
Always Extra Heavy Overnight uses a cellulose-based absorbent core (standard for the category) with a plastic backing layer and an unspecified waterproof coating. The coating is the primary concern: manufacturers typically use either Teflon-type coating-based coatings, polyurethane, or wax-based formulations to prevent leakage, but Always has not publicly disclosed which. Cellulose itself is low-risk, but the plastic backing and its adhesives can shed microfibers and may leach additives during prolonged moisture exposure against skin.
The brand's record and disclosure
Procter and Gamble (Always's parent company) has faced ongoing criticism for lack of transparency on PFAS and other chemical additives in menstrual products, but has not issued a public recall or safety warning specific to this product. The brand does not prominently disclose coating composition, flame retardants, or restricted chemical screening on product packaging or corporate materials. Industry-wide, Always is considered mainstream but less transparent than smaller brands with third-party certifications.
How it compares in its category
Always Extra Heavy Overnight sits in the mid-market segment: more affordable and widely available than certified organic alternatives (Seventh Generation, Cora), but less transparent than those competitors on chemical safety. Most mainstream pads (Kotex, Tampax) share similar disclosure gaps on coating composition. Products certified by organizations like the Cradle to Cradle or bearing the Leaping Bunny logo tend to offer higher chemical accountability, which Always Extra Heavy does not.
If you buy it
Change pads every 4-8 hours to minimize prolonged skin contact with the plastic backing and reduce microfiber exposure. Avoid storing in hot, humid environments (like bathrooms without ventilation) as moisture and heat can increase leaching from adhesives and coatings. If you experience irritation, itching, or rash, discontinue and consider a product with published ingredient transparency. Consider switching to certified or organic alternatives if you are sensitive to undisclosed chemical additives.
