Where these two actually differ
- We flag Volatile organic compounds (VOC) / respiratory irritant, Skin and eye irritation from surfactants and solvents, Inadequate label toxicity and safety information and Residual solvent on treated fabric 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 liquid cleaning concentrate, likely surfactants and solvent base 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 →
