High-Risk Cleaning Ingredients to Avoid

Cleaning products are some of the most concentrated sources of toxins in the home. Many contain chemicals designed to kill germs, dissolve grease, or create a “clean” smell — but they often harm your lungs, skin, and long-term health.

⚠️ Problem ingredients:

  • Chlorine bleach: Strong oxidizer that irritates the lungs, eyes, and skin. Forms toxic gases when mixed with other cleaners.
  • Ammonia: Harsh irritant, especially dangerous when combined with bleach (produces chloramine gas).
  • Quaternary ammonium compounds (quats): Disinfectants linked to asthma, allergic reactions, and antimicrobial resistance.
  • Phenols and cresols: Found in some disinfectants; can cause skin burns and liver/kidney effects.
  • Glycol ethers: Used in glass cleaners and degreasers; reproductive toxicants in animal studies.
  • Artificial fragrance: Often contains phthalates, VOCs, and formaldehyde-releasing compounds.
  • “Antibacterial” agents (e.g. triclosan): Endocrine disruptor; banned in soaps but still found in some sprays and personal care items.

Even products labeled “green” or “natural” can include these chemicals if you don’t read the fine print.
