Today's Chemical:

DMDM Hydantoin

EWG Risk Score:


Why it's a risk:

The biggest concern that DMDM Hydantoin carries is that it can release or be contaminated with the carcinogen formaldehyde. It actually works as a preservative by releasing formaldehyde. It is also a strong skin, eye, and lung irritant. It has also been known to trigger an immune response that can include burning, itching, blistering, or scaling of skin.

Types of products it's in:

Shampoo, bodywash, sunscreen, hand lotion, facial moisturizers, baby wipes

DDF Organic


Bumble & Bumble (Not Bubble & Bee!)


Desert Essence


Irish Spring



Steph's Opinion: Isn't it interesting that these brands have built a reputation for being gentle and safe but they'll use a preservative like DMDM Hydantion?! Think of this the next time you see their commercial...yes, Dove may not leave soap scum, but it'll outgas formaldehyde! And in baby wipes! It's just sad when there are other safer preservatives that don't leave traces of carcinogens.
