Baby Safety / Compounds / PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA)

Is PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA) safe for babies and kids?

High risk for kids

Infants accumulate PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA) through breast milk (bioconcentration), placental transfer, and dust ingestion. Persistent pollutants concentrate in fatty tissues with extended half-lives in developing organisms.

What is pfmpa (perfluoro-2-methoxypropanoic acid, pmpa)?

The IUPAC name is 2,2,3,3-tetrafluoro-3-(trifluoromethoxy)propanoic acid.

Also known as: 377-73-1, Perfluoro-3-methoxypropanoic acid, 2,2,3,3-tetrafluoro-3-(trifluoromethoxy)propanoic acid, perfluoromethoxypropionic acid.

Risk for babies

High risk

Infants accumulate PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA) through breast milk (bioconcentration), placental transfer, and dust ingestion. Persistent pollutants concentrate in fatty tissues with extended half-lives in developing organisms.

Neonates and infants up to 12 months have incomplete blood-brain barrier development, immature Phase I/II metabolic enzymes (particularly CYP3A4, UGT1A1), and higher gastrointestinal permeability. Equivalent doses produce higher internal concentrations and longer residence times.

What to do: Minimize infant exposure through source control. For breastfeeding mothers: reduce maternal exposure. For formula-fed infants: use certified low-migration bottles and verified water sources. Consult pediatrician regarding any concerns.

Risk for pregnant and nursing people

Elevated risk

PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA) persists in maternal adipose tissue and is mobilized during pregnancy and lactation. Lipophilic pollutants concentrate in breast milk and cross the placenta during critical developmental windows.

Suspected reproductive toxicant (GHS H361) or suspected endocrine disruptor. Precautionary approach warranted. Animal studies or limited human data suggest developmental toxicity potential.

What to do: Minimize exposure during pregnancy and lactation. Consult healthcare provider regarding specific risks. Consider alternative products with lower hazard profiles.

Regulatory consensus

2 regulatory and scientific bodies have classified PFMPA (Perfluoro-2-methoxypropanoic acid, PMPA). The classifications differ — that's the data.

NC DEQ——Part of NC GenX contamination investigation at Chemours Fayetteville Works

Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.

Where kids encounter pfmpa (perfluoro-2-methoxypropanoic acid, pmpa)

  • Drinking Water — Cape Fear River, NC (downstream of Chemours), Municipal water in Fayetteville, NC area
    Detected alongside HFPO-DA (GenX) near Chemours plant
  • Industrial Discharge — Fluoropolymer manufacturing effluent
