I found a link recently to the Household Products Database. Created by the National Library of Medicine, it provides health & safety information on household products.
You can look up information by product or ingredient. For example, enter Fragrance in the ingredients search and you get this long list. I didn’t read the entire list, but I did look through it.
I learned some interesting things. For example, did you know you could buy Cologne for your pet??? I knew that if you took a pet to be groomed that they put stinky stuff on them. But worse – Crest Toothpaste is on the list as containing fragrance??!? What in the world? Why? Oh, sorry, probably cannot apply logic to this… 😕
