Documented risks

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.

Triclosan: An endocrine disruptor linked to antibiotic resistance. Restricted in the EU and banned in US over-the-counter antibacterial soaps, but still allowed in some products.
