Quick answer: Both score equally on our risk model. Calcium Disodium EDTA is — in the EU and — in the US; Retinyl palmitate is restricted in the EU and allowed in the US.

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.
Retinyl palmitate is a vitamin A ester used in anti-aging skincare and sunscreen.
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.
Retinyl palmitate: The EU caps vitamin A levels over concerns it may accelerate skin damage in sunlight; the US does not restrict it.
