Re‐evaluation of name of hydrogenated poly‐1‐decene (E 907) as food additive

Abstract

The Panel on Food Additives and Flavourings added to food (FAF) provided a scientific opinion re‐evaluating the safety of hydrogenated poly‐1‐decene (E 907) when used as a food additive. Hydrogenated poly‐1‐decene (E 907) is authorised as a food additive in the EU in accordance with Annex II to Regulation (EC) No 1333/2008. Hydrogenated poly‐1‐decene is of low acute toxicity and does not raise concern for genotoxicity. Toxicity and carcinogenicity, as well as reproductive and developmental toxicological studies, were not available; therefore, the Panel based the derivation of the acceptable daily intake (ADI) on the no observed adverse effect level (NOAEL) identified in the subchronic study in rats and established an ADI of 20 mg/kg bw per day. Dietary exposure to hydrogenated poly‐1‐decene (E 907) from its use as a food additive was calculated based on regulatory maximum level exposure assessment scenario. Mean exposure to hydrogenated poly‐1‐decene (E 907) from its use as a food additive ranged from no exposure in infants to 2.35 mg/kg bw per day in toddlers. The high exposure to hydrogenated poly‐1‐decene (E 907) ranged from 0 mg/kg bw per day in infants and adults to 6.69 mg/kg bw per day in toddlers. The exposure estimates in the regulatory maximum level exposure assessment scenario did not exceed the ADI of 20 mg/kg bw per day for all population groups. The Panel concluded that the exposure to hydrogenated poly‐1‐decene (E 907) does not raise a safety concern when used at the maximum permitted levels.

Revisiting the Potential of Group VI Inorganic Precatalysts for the Ethenolysis of Fatty Acids through a Mechanochemical Approach

“…Recent years have seen a growing interest in the development of a broad portfolio of bioderived compounds as alternatives to the traditional fossil fuel-derived chemicals. − Naturally available vegetable oils (VOs) are a major feedstock for biorefineries, , leading to a variety of so-called oleochemicals with ramifications in the synthesis of surfactants, , lubricants, polymers, − and other useful compounds such as carbonated vegetable oils. ,− An important class of oleochemicals is represented by functional olefins such as 9-decenoic acid methyl ester (9-DAME), which is a valuable fine chemical with potential application for the preparation of biodiesel surrogates, , bioaviation fuel, and as a starting material for the preparation of diverse functional compounds. − 9-DAME can be obtained from the ethenolysis (metathetic cleavage with ethene) of oleic fatty acid ester chains derived from VO transesterification leading to the formation of an equivalent of 1-decene, a valuable α-olefin used for the synthesis of polymers and food additives just to cite some applications. The catalytic ethenolysis of oleic fatty acids to produce 9-DAME and 1-decene has been studied in the past. ,, Homogeneous ruthenium alkylidene complexes are powerful catalysts for the ethenolysis of methyl oleate, showing high catalytic turnover at moderate methyl oleate conversion under 10 bar ethylene. , However, given the high cost of ruthenium-based catalysts and the geographically restricted availability and critical resource status of ruthenium, there has been an increasing interest toward alkylidene complexes of inexpensive and ubiquitously available metals such as molybdenum. , A homogeneous molybdenum imido alkylidene monoaryloxide monopyrrolide complex was reported to carry out the ethenolysis of methyl oleate with high yields and selectivity at room temperature under 10 bar ethylene .…”
