Where these two actually differ

  • We flag Enzyme sensitization (protease/amylase) and Residual surfactant skin irritation on the Dirty Labs and not on the Dirty Labs.
  • We flag Residue accumulation on textiles on the Dirty Labs and not on the Dirty Labs.
  • The Dirty Labs is Plant-based surfactants, enzymes, water where the Dirty Labs is aqueous concentrate, bio-based surfactants, which is most of the difference in these two grades.

Both products run through the same public rubric, which covers 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 →
