Is this safe for 0-6 month old newborns to use Dmdm Hydantoin?

🚫
NO - AVOID
Danger Score: 8 (Lower is safer)
Quick Answer: Dmdm Hydantoin avoid - not safe for 0-6 month old babies when used in topical products. Always consult your pediatrician for newborns.

ℹ️General Overview

For newborns and babies 0–6 months, Dmdm Hydantoin is best avoided. It can release formaldehyde and is known to cause skin irritation and allergic reactions, and babies have very sensitive, thin skin.

What to Do

Choose products labeled preservative-free or free of formaldehyde-releasing preservatives for infants. Avoid using products that list Dmdm Hydantoin on the ingredient label on baby skin, especially on the face, folds, or damaged skin. If you must use a product that contains it, prefer short contact (rinse-off) products and test on a small area first; stop use at the first sign of redness, rash, swelling, or itching.

⚠️Warnings

Watch for redness, bumps, swelling, itching, or any new rash after using a product with this ingredient — these are signs of an allergic reaction or irritation (based on safety reviews cited for this ingredient, including Cosmetic Ingredient Review and other regulatory sources). There is also a contamination concern for formaldehyde noted in the ingredient data; do not use on broken or inflamed skin. Some countries restrict or limit its use in certain cosmetics (Japan cited), which is why extra caution is advised for infants.

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.
