Where these two actually differ

  • We flag Volatile organic compounds (VOCs) and inhalation exposure during application, Dermal and respiratory irritation from coating components, Coating durability and product replacement frequency and Contamination of treated fabric and household surfaces on the Scotchgard and not on the Seventh Generation.
  • We flag Enzyme sensitization or respiratory irritation, Surfactant skin irritation (concentrated form) and Fragrance allergen content on the Seventh Generation and not on the Scotchgard.
  • The Scotchgard is Proprietary water-repellent coating, composition undisclosed where the Seventh Generation is water-based surfactant formula, which is most of the difference in these two grades.
  • The gap is 55 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 Scotchgard grade, at 35% confidence against 78%, because it discloses less.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
