We trust our dishwashers to clean our plates, cups, and utensils—but have you ever thought about what’s lurking in your dishwasher detergent? Many conventional dishwasher detergents contain harsh chemicals that can leave toxic residues on your dishes, exposing you and your family to harmful substances with every meal.

Recent research has also raised new concerns about the effects of dishwasher detergents beyond just surface contact. A study published in The Journal of Allergy and Clinical Immunology found that dishwasher detergents and rinse aids can cause gut epithelial barrier damage, potentially leading to inflammation, digestive issues, and increased risk of food sensitivities. This highlights the importance of switching to a safer, non-toxic alternative to protect both your health and the environment.

In this blog, we’ll break down the toxic ingredients found in most dishwasher detergents and show you how to make your own safe, eco-friendly alternative at home.

Harmful Chemicals in Dishwasher Detergent

Many store-bought dishwasher detergents contain chemicals that can harm both your health and the environment. Here are some of the worst offenders:

1. Phosphates

  • Used to break down grease and food particles, phosphates contribute to water pollution and can lead to algae overgrowth in lakes and rivers, disrupting ecosystems.

  • Exposure to high levels can also cause skin irritation and respiratory issues.

2. Chlorine Bleach

  • While effective at killing bacteria, chlorine bleach is a known irritant that can cause skin burns, respiratory problems, and eye irritation.

  • When mixed with other chemicals, it can release toxic fumes harmful to both humans and pets.

3. Artificial Fragrances & Dyes

  • Many detergents contain synthetic fragrances and artificial dyes, which can trigger allergic reactions, skin sensitivities, and even hormone disruption.

  • These ingredients don’t break down easily in water, contributing to environmental pollution.

4. Sodium Lauryl Sulfate (SLS) & Sodium Laureth Sulfate (SLES)

  • These foaming agents are often contaminated with 1,4-dioxane, a potential carcinogen.

  • They can strip natural oils from your skin, leading to dryness and irritation.

5. Isothiazolinone-Based Antimicrobial Agents

  • Methylisothiazolinone (MIT) and Benzisothiazolinone (BIT) are preservatives used to prevent bacteria and mold growth in liquid dishwasher detergents.

  • These chemicals are neurotoxic and have been linked to lung, skin, and eye irritation.

  • Prolonged exposure may increase the risk of allergic reactions, contact dermatitis, and respiratory issues.
