2019年5月16日，据欧盟食品安全局（EFSA）消息，欧洲食品安全局食品接触材料、酶和加工助剂小组（CEP）评估了亚磷酸（Phosphorous acid）、三苯酯（triphenyl ester）、C10-16烷基酯（alkyl esters）和α-氢-ω-羟基聚[氧基（甲基-1,2-亚乙基）。聚合物（polymer with alpha‐hydro‐omega‐hydroxypoly[oxy（methyl‐1,2‐ethanediyl）],）在食品接触性材料中的安全性。
经过评估，CEP小组得出结论，所评估物质不会对消费者的安全造成影响。
部分原文报道如下：
The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids （CEP Panel） assessed the safety of the substance 'phosphorous acid, triphenyl ester, polymer with alpha‐hydro‐omega‐hydroxypoly[oxy（methyl‐1,2‐ethanediyl）], C10-16 alkyl esters', obtained by reaction of ■■■■■， when used as an additive at up to 0.2% w/w in high impact polystyrene. The plastic, in the form of films and articles, is intended for contact with aqueous, acidic, low‐alcohol and fatty foods for long‐term storage at room temperature and below, after hot‐fill and/or heating up to 100°C for up to 2 h. based on genotoxicity tests with negative results, the Panel considered that there is no evidence of mutagenicity and chromosomal damage of the substance and its phosphate form. From a repeated dose 90‐day oral toxicity study in rats, the Panel identified the no‐observed‐adverse‐effect level as 50 mg/kg body weight （bw） per day. No effects of induced delayed neurotoxicity in hens were observed.
