F why Formaldehyde is yelow 6? It's dengerous for the skin! analysis of chemicals constituents on this page is misleading

They made it even number 1 now, i think they forgot the 0 next to the 1 because in ewg its a hazardous 10 and here its a 1

Agreed that Formaldehyde should be 10 as it is a carcinogen to human by IARC, https://monographs.iarc.fr/list-of-classifications-volumes/
