This is the user-friendly name for the most hazardous chemical in my Eucerin. What makes it potentially hazardous? It releases the same stuff that your lab frog was floating in before you dissected it in 9th grade biology. Formaldehyde. The Big F is apparently released in small quantities by this DMDM stuff, and in large doses, F causes all sorts of problems. Supposedly, my Eucerin does not have enough of the junk to cause problems, and is approved by the EU's most recent laws governing which chemicals are allowed in cosmetics. The other problem, though, is that DMDM Hydantoin causes allergies in susceptible individuals, one of whom is my husband. Which means my daughter may be a future candidate for allergies to the same chemicals (she already has some of his other allergy issues). I guess that means maybe I shouldn't be slathering it all over my face and then ask my family members to kiss me.
Another usual suspect in my lotion is PEG-40 Castor Oil. Also apparently safe in small quanities, in large amounts it is a neuro-toxin and at lesser amounts can trigger an immune response, leading to itching, burning, and other pleasant side effects.
So far, this is a really uplifting journey I've embarked upon. And this product is a 3 out of 10. How much do you wanna bet I use plenty of products that have earned a higher number?
