2020年5月6日，据欧盟食品安全局（EFSA）消息，欧盟食品添加剂和调味剂小组（ FAF ）重新评估了二甲基聚硅氧烷 （Dimethyl polysiloxane）（E 900）作为食品添加剂的安全性。
经过评估，专家小组认为在规定的用途和使用水平下，二甲基聚硅氧烷作为食品添加剂不存在安全问题。部分原文报道如下：
The Panel on Food Additives and Flavourings （FAF） provided a scientific opinion re‐evaluating the safety of dimethyl polysiloxane （E 900） as a food additive. E 900 was evaluated by the Scientific Committee on Food （SCF） in 1990 and agreed with the Acceptable Daily Intake （ADI） of 1.5 mg/kg body weight （bw） per day previously established by Joint FAO/WHO Expert Committee on Food Additives （JECFA） in 1974. Dimethyl polysiloxane was only absorbed to a very limited extent from the gastrointestinal tract following oral administration and the vast majority was excreted unchanged in the faeces. Corneal opacities and other effects on cornea were observed in studies in rats. These effects are considered to be caused by direct contact with the test substance in the feed and/or with the test substance in the faeces and not due to systemic exposure.
