Why Plastic Pads Trap Heat and Moisture

In recent commercial positioning, Always has introduced new marketing narratives surrounding Always Infinity & Ultra Thin Pads:
“Marketing Infinity FlexFoam and Ultra Thin pads as breathable protection while using synthetic rayon, chlorine bleaching, and occlusive plastic backsheets.”

While commercial advertising presents these formulations as daily self-care staples, an anatomical inspection of the
underlying chemistry reveals systemic biological friction. Mucosal tissue and delicate pelvic anatomy lack the thick keratinized
stratum corneum found on outer limbs. When synthetic compounds, petrochemical surfactants, and hidden scent fixatives touch
vascular mucous membranes, transdermal absorption occurs rapidly—bypassing first-pass hepatic filtration.

The Toxicological Footprint

• Synthetic rayon & polyolefin microplastics: Synthetic rayon & polyolefin microplastics
• Elemental chlorine bleaching dioxins: Elemental chlorine bleaching dioxins (PCDDs/PCDFs)
• Adhesive phthalate plasticizers: Adhesive phthalate plasticizers (DEHP, DBP)
• Occlusive polyethylene backsheets trapping moisture: Occlusive polyethylene backsheets trapping moisture
