Ultra Heavy Absorbency Underpad vs Incontinence Pads: which is safer?

Where these two actually differ

• We flag Waterproof backing composition undisclosed, Off-gassing from synthetic backing and Skin contact irritation from coating additives on the McKesson and not on the Eco By Naty.
• We flag Heavy metals in cellulose or plant-derived materials on the Eco By Naty and not on the McKesson.
• The McKesson is cellulose, absorbent core with waterproof backing (composition unspecified) where the Eco By Naty is Bamboo-derived viscose, cotton, plant-based absorbent core, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Eco By Naty is the one to buy.
• We are less certain about the McKesson grade, at 35% confidence against 78%, because it discloses less.
