Extra Heavy Overnight Maxi Pads vs Chlorine Free Maxi Pads: which is safer?

Where these two actually differ

• We flag Waterproof coating composition (unspecified), Microfiber and plastic backing degradation, Adhesive leachables and Contact dermatitis from undisclosed additives on the Always and not on the Seventh Generation.
• We flag Fragrance allergen content on the Seventh Generation and not on the Always.
• The Always is cellulose, absorbent core, plastic backing with unspecified waterproof coating where the Seventh Generation is organic cotton, wood pulp, which is most of the difference in these two grades.
• The gap is 75 points, wide enough that this is not a close call, and the Seventh Generation is the one to buy.
• We are less certain about the Always grade, at 45% confidence against 78%, because it discloses less.
