Where these two actually differ
- We flag Volatile organic compound (VOC) inhalation, Skin sensitization and irritation, Eye contact hazard and Fabric damage or color bleeding on the Carbona 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 Carbona.
- The Carbona is Aliphatic hydrocarbon solvent blend where the Seventh Generation is water-based surfactant formula, which is most of the difference in these two grades.
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 →
