Brominated Flame Retardants vs Propyl Gallate: which is worse?
Quick answer: Brominated Flame Retardants carries the heavier risk profile. Brominated Flame Retardants is — in the EU and — in the US; Propyl Gallate is — in the EU and — in the US.

What is Brominated Flame Retardants?
Brominated flame retardants (BFRs) are a class of synthetic chemicals added to consumer products and materials to reduce flammability. They include polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), and others. While not direct food additives, they contaminate the food supply through environmental pathways and food packaging.
What is Propyl Gallate?
Propyl gallate is a synthetic antioxidant preservative derived from gallic acid and propanol. It prevents oxidation of fats and oils, extending shelf life of fat-containing foods. It is often used in combination with BHA and BHT for synergistic antioxidant effect. Chemical formula: C10H12O5.
Documented risks
Brominated Flame Retardants: PBDEs and other BFRs are endocrine disruptors, neurodevelopmental toxicants, and probable carcinogens. They accumulate in human adipose tissue, breast milk, and blood. PBDEs were found in 100% of samples in multiple US population biomonitoring studies. US women have PBDE body burdens 10-100 times higher than European women, reflecting the US's historically heavy PBDE use before bans. Neurodevelopmental effects: multiple studies have associated prenatal PBDE exposure with lower IQ, attention deficits, and behavioral problems in children. A 2012 Environmental Health Perspectives study found inverse associations between PBDE cord blood levels and child IQ and behavioral outcomes. Thyroid disruption: BFRs structurally mimic thyroid hormones and compete with thyroid hormone binding proteins, disrupting the thyroid axis — critical for fetal brain development. Carcinogenicity: some PBDEs are associated with thyroid cancer risk in human studies. PBDEs enter the food supply primarily through fatty fish (salmon, tuna), meat, dairy, and some contaminated produce from biosolid-amended soils.
Propyl Gallate: Animal studies have shown propyl gallate may cause liver damage at high doses. Concerns about estrogenic activity have been raised — some studies suggest propyl gallate may weakly mimic estrogen. Contact dermatitis and allergic reactions are documented in both food and cosmetic applications. Japan banned propyl gallate for food use as part of its precautionary approach to synthetic food preservatives. NTP bioassays found dose-dependent liver effects. EFSA's re-evaluation set an ADI of 0.1 mg/kg body weight — one of the lowest ADIs for food additives, reflecting toxicological concern.
