VeriMomIs phosphoric acid safe for baby skin?
There is no evidence that phosphoric acid is a reproductive toxin for infants, but it is a known corrosive (H314) and infant skin has a less mature barrier and higher surface-area-to-weight ratio. Therefore exposure score is increased by +1 for baby skin — risk is primarily from local irritation/chemical burn rather than systemic developmental toxicity. Formulations for infants should avoid concentrations that can cause skin corrosion.
