Frequently asked questions
- Is diazolidinyl urea safe during pregnancy?
- Formaldehyde-releaser of the same class as DMDM hydantoin — slowly releases a Group 1 carcinogen. Common contact allergen. Listed on most pregnancy-skincare avoid lists.
- Is diazolidinyl urea safe while breastfeeding?
- Same hazard basis as pregnancy (no harmonised CMR classification; CIR & EU CosIng allow use up to 0.5%). Mechanistic concern is theoretical (formaldehyde release; in vitro cytotoxicity reported). Systemic exposure from normal topical cosmetic use is considered low but measurable, so transfer into breastmilk is plausible but not documented; therefore exposure scored low. Sources: CIR, CosIng (EU Regulation), PubMed study on in vitro effects, ECHA registration info.
- Is diazolidinyl urea safe for baby skin?
- Hazard and mechanistic scoring kept same as adult (no infant‑specific evidence of greater hazard). Exposure score increased by +1 for infants because immature skin and higher surface‑area‑to‑weight ratio increase absorption; topical use therefore gives moderate exposure potential. No infant dermal toxicokinetic or developmental studies specific to 0–3 yr were identified. Sources: EU CosIng (Annex V), CIR, in vitro studies (neural progenitor cytotoxicity), EWG summary.
