🚨
NOT RECOMMENDED
Danger Score: 6 (Lower is safer)
Quick Answer: Dmdm Hydantoin not recommended for 1-2 year old toddlers when used in topical products. Watch for toddler-specific sensitivities.

ℹ️General Overview

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.

What to Do

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.

⚠️Warnings

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.

Safety Risk Labels

This ingredient has the following documented risks:

Immune system: Safety reviewers report strong evidence that DMDM Hydantoin can cause skin allergy and immune reactions in people. This is called out by the Cosmetic Ingredient Review and supported by national chemical agency findings and peer‑reviewed reports.
Irritant: There is clear human evidence that this ingredient can irritate skin, eyes, or lungs. That conclusion is reported by the Cosmetic Ingredient Review based on case and study data.
Cancer: High contamination concern: DMDM Hydantoin can contain or release formaldehyde, and formaldehyde is linked to cancer by international cancer evaluators. Because of this contamination risk, cancer is a real concern even though direct cancer evidence for the ingredient itself is limited.
Banned: Some governments limit or prohibit this ingredient in certain cosmetic types and set concentration limits; the Japan Ministry of Health has specific restrictions and prohibitions for some products.
Absorbed: Review notes indicate enhanced skin absorption for this ingredient, meaning it can pass through the skin and increase internal exposure—this finding is reported by industry and safety reviewers.
Eczema: Because it is a known skin allergen and irritant, DMDM Hydantoin can trigger or make eczema and similar skin conditions worse in sensitive children, as noted by safety reviews and chemical agency reports.
