Overview
- Öko-Test’s April 2026 comparison of 26 hand dishwashing liquids gave Fit Original the lowest grade after a lab found formaldehyde above the limit used for rinse‑off cosmetics.
- The testers applied cosmetic thresholds because dish soap often contacts skin during washing in ways similar to shower gel or shampoo.
- Öko-Test suspects the preservative bronopol released the chemical, which the European Chemicals Agency classifies as acutely toxic and probably carcinogenic.
- Fit says it does not add formaldehyde and maintains the legally compliant formula can release only very small amounts from preservatives under certain conditions.
- No recall or regulatory action has been reported, though media coverage has amplified the finding and focused consumer attention on ingredient safety.
- Only two products earned top marks in the test—Rewe’s Ja! Ultra Power concentrate and Sodasan Lemon & Lime—highlighting wide gaps in both cleaning performance and chemical profiles across the market.
