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.
Hidden ingredients / Other evidence
Some cleaning makers disclosed nothing in 2012, while others used vague terms such as 'surfactant' and 'solvent' for ingredients.
Weak evidence: Qualitative statement by an advocacy group; no counts or product examples on this page.

Hidden ingredients / Measured in people or real products
In the same study, scented household cleaning products were not linked to higher levels of any measured chemical, and urine BPA was lower in children from homes that used them (ratio 0.69, 95% CI 0.49-0.98), so 'scented products' did not behave as one exposure.
Weak evidence: Likely chance or residual confounding on a wide multi-model estimate; shows heterogeneity of product categories rather than a protective effect.
