How the library works
- An entry gets a page once it has a written description and appears in at least three researched products. Below that we leave the name as plain text on the product pages rather than publishing a page with nothing on it.
- US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Position tells you about relative amount only above that line, and we never convert a position into a percentage.
- We do not publish safety scores or hazard grades. Where a regulator has published a restriction or a use condition, we state it and cite it; otherwise we describe what the ingredient does and stop.
- Nothing on these pages is paid placement, and we do not sell any of the products they link to.
