Don’t take our word for it. Here’s every fact on this site, with its evidence grade, its caveats, and a link to the source, so you can check us.
We start you on the strong ones: findings that have been replicated or come from one large, well-controlled study. Moderate and weak facts are here too, labeled for what they are. Use “Link to this fact” to share a single card.
The industry / Other evidence
EWG linked companies' ingredient disclosure to 'pressure from customers and the threat of federal regulation', saying that is why most cleaning makers list at least some ingredients.
Weak evidence: EWG's explanation of company motives, not tested; no regulatory history is given.

The industry / Other evidence
EWG states it accepts no programmatic funding from food, household-cleaning, or personal-care companies, no funding for corporate-sponsored research, and no payment of any kind for inclusion or scoring in Skin Deep, Guide to Healthy Cleaning, or Food Scores.
Weak evidence: This is a policy statement by EWG itself; 'programmatic funding' is not defined and no audit of compliance is on the page.
