For toddlers (1-2 years) DMDM Hydantoin is moderately risky. It can cause skin irritation or allergic reactions in young children and may contain or release small amounts of formaldehyde. Be cautious, especially for children with sensitive skin or eczema.
If you are using a lotion or cream for a toddler, choose products that say they are free of formaldehyde-releasing preservatives or pick products made for sensitive or baby skin. Patch-test a small area first (apply a little on the inner forearm and wait 24–48 hours). Stop use right away if you see redness, rash, itching, or swelling. Avoid putting products with this ingredient on broken skin. Prefer simpler baby-specific products when possible.
Watch for signs of an allergic reaction (redness, itching, rash, swelling) — human skin allergy and irritation have been reported by industry safety reviewers and peer-reviewed studies (Cosmetic Ingredient Review and peer-reviewed literature). There is also a contamination concern with formaldehyde reported and some countries (Japan) have limits or bans on certain uses. If your child has eczema, very sensitive skin, or a history of allergies, avoid products with this ingredient and consult your pediatrician or dermatologist.
