VeriMomShould I Avoid pentetic acid During Pregnancy? | VeriMom
Diethylenetriaminepentaacetic acid (pentetic acid, DTPA; CAS 67-43-6) has an EU harmonised classification Repr.1B H360D in Annex VI (legal, harmonised CLP), so by regulatory calibration this is a confirmed reproductive hazard (h=3). The likely mechanism is demonstrated chelation of essential metals (e.g., zinc) with resulting developmental effects in animal studies (m=2). For typical topical cosmetic use, DTPA is a highly polar chelator with low expected dermal absorption, so exposure from normal dermal application is expected to be negligible (e=0). Sources: EU delegated regulation / Annex VI listing (Repr.1B H360D). (See EUR-Lex and ECHA).

FAQ
- Is pentetic acid safe during pregnancy?
- Diethylenetriaminepentaacetic acid (pentetic acid, DTPA; CAS 67-43-6) has an EU harmonised classification Repr.1B H360D in Annex VI (legal, harmonised CLP), so by regulatory calibration this is a confirmed reproductive hazard (h=3). The likely mechanism is demonstrated chelation of essential metals (e.g., zinc) with resulting developmental effects in animal studies (m=2). For typical topical cosmetic use, DTPA is a highly polar chelator with low expected dermal absorption, so exposure from normal dermal application is expected to be negligible (e=0). Sources: EU delegated regulation / Annex VI listing (Repr.1B H360D). (See EUR-Lex and ECHA).
- Is pentetic acid safe while breastfeeding?
- Harmonised Repr.1B (H360D) classification applies regardless of exposure route and therefore is used here (h=3). Mechanistic concern is the same (chelating-induced essential metal depletion shown in animals; m=2). With normal topical cosmetic use, systemic transfer into breastmilk is unlikely because dermal absorption is expected to be very low (e=0), but harmonised classification still indicates potential hazard if systemic exposures occur. Sources: EUR-Lex Annex VI; animal/ mechanistic literature on chelators and developmental effects.
- Is pentetic acid safe for baby skin?
- Because DTPA has a harmonised Repr.1B classification (H360D), the hazard score for infants remains h=3 (do not downgrade). Mechanistically the same chelation-mediated developmental/reproductive concern applies (m=2). Adult dermal absorption is expected to be minimal, but infant skin has higher surface-area-to-weight and immature barrier; per the scoring rules this increases exposure by +1 (adult e=0 → baby e=1) unless reliable dermal non-absorption data exist. Therefore exposure for babies via topical products is scored e=1. Sources: EUR-Lex Annex VI (harmonised CLP), ECHA substance information, and literature on chelators’ developmental effects.
