Following an evaluation of the existing toxicity data on hydrogenated poly-1-decene (E 907), EFSA has increased the acceptable daily intake (ADI), set by the Scientific Committee on Food (SCF) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) in 2001, from 6 to 20 mg/kg bw. The critical study remained a 90-day dietary test in rats, but effects previously considered adverse (altered appearance of the animals’ coats, haematological findings and lower liver weights) were no longer considered toxicologically relevant. Based on the new ADI, exposure to hydrogenated poly‑1‑decene in foods is thought not to present a safety concern to consumers.
