What is Calcium Disodium EDTA?

Calcium disodium EDTA (ethylenediaminetetraacetate) is a chelating agent used as a food preservative. It binds metal ions (particularly iron and copper) that would otherwise catalyze oxidative and color-degradation reactions in foods. It prevents color loss, flavor changes, and bacterial growth in certain foods.

What is Triclosan?

Triclosan is an antibacterial and antifungal agent.

Documented risks

Calcium Disodium EDTA: EDTA chelates essential minerals including zinc, iron, calcium, and magnesium in the gut, potentially reducing absorption of these nutrients with regular consumption. Animal studies at high doses show reproductive toxicity and zinc deficiency effects. EFSA's safety assessment noted that EDTA could reduce zinc bioavailability at consumption levels that could be reached by high consumers of EDTA-containing foods. The ADI is 1.9 mg/kg body weight. EDTA's poor biodegradability also makes it an environmental concern — it accumulates in water supplies and can mobilize heavy metals in sediments.

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.
