Chemical Safety Databases
By Dr. Meg Christensen | Updated February 2026
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
Ultra- naturally minded people think the EWG is evil for rating products as safe when they’re not, and super-conventional people think it’s evil for making safe products seem more harmful than they are. The EWG stirs up a lot of emotions! I think they’re the best thing we have for ingredient transparency in cleaning products so far, and that it’s a great starting point that you can take with a grain of salt. They’re excellent for understanding how scary-sounding chemicals actually impact us — and are sometimes surprisingly safe.
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.
