Chemical Safety Databases
Dr. Meg Christensen is the founder of Interior Medicine, a physician-created resource on non-toxic home products and household exposures. Her layer-by-layer analysis of materials and products draws on her background in medicine, biochemistry, epidemiology, and clinical research.

Independent databases for understanding specific chemicals that are ingredients in home products.
Collaborative for Health & Environment Toxicant and Disease Database
The Collaborative for Health and Environment has an easy-to-use, searchable database that summarizes links between chemical contaminants and approximately 180 human diseases or conditions.
European Chemicals Agency Database
If you’re unsure of the health effects of any chemical listed in a product’s ingredients, you can search for them in the European Chemicals Agency database by name or CAS number. It’s definitely a little technical, but can be helpful, if that’s your style.
Environmental Working Group (EWG) Guide to Healthy Cleaning
The EWG only uses hazard, not true risk, to assess ingredients, and some say they are not consistent about their precautionary stance, but, for now, they’re the best thing we have for understanding ingredients in cleaning products, and that it’s a great starting point that you can take with a grain of salt. Sometimes scary-sounding chemicals are sometimes surprisingly safe. (Why the difference between hazard vs. risk matters is covered in my free course.)
Will + Perkins Transparency
The Precautionary List database allows you to sort by human health concern (reproductive toxicity, eye irritation, etcetera) and generates a list of chemicals in common interior products and building materials that may contribute to those concerns.
