Denmark: Consumer Council Tænk Finds Harmful Chemicals in Dishwasher Detergents

In April 2026 the Danish Consumer Council Tænk published testing showing that several popular dishwasher detergents contain benzotriazole and other problematic chemicals, including a suspected carcinogen, while many eco-labelled, fragrance-free products avoid these substances. Although no recalls or regulatory action have followed yet, the findings increase pressure on detergent manufacturers to reformulate, reinforce the value of trusted ecolabels, and may accelerate tighter controls on persistent endocrine-disrupting ingredients in cleaning products.
