Safety of Cetylated Fatty Acids as a Novel Food pursuant to Regulation (EU) 2015/2283

Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on an application for cetylated fatty acids as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF concerns primarily a mixture of cetylated myristic acid and cetylated oleic acid synthesised from cetyl alcohol, myristic acid and oleic acid, and to a lesser degree, other cetylated fatty acids and other compounds from olive oil. The NF is intended for use in food supplements for the general adult population. The highest dose tested in a subchronic toxicity study in rats, i.e. 4,500 mg/kg per day, was considered to be the no‐observed‐adverse effect level. By applying the default uncertainty factor of 200 as suggested by the EFSA Scientific Committee (2012), and considering a default body weight of 70 kg for the adult target population, this would result in an intake of 1.6 g per day, which is lower than the maximum intake proposed by the applicant (i.e. 2.1 g per day). The Panel concludes that the NF, cetylated fatty acids, is safe at an intake of 1.6 g per day for the intended target population, i.e. adults.
