COMMISSION IMPLEMENTING REGUL ATION (EU) 2017/59 
of 14 December 2016 
concer ning the author isation of 1,1-dimetho xy-2-phenylethane, phenethyl formate, pheneth yl 
octa noate, phenethyl isobutyrate, phenethyl 2-methy l-butyrate and phenethyl benzoate as feed 
additiv es for all animal species 
(Text with EEA relevance) 
THE EUR OPEAN COMMISSION, 
Having regar d to the Treaty on the Functioning of the European Union, 
Having regar d to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 
on additives for use in animal nutr ition (1), and in particular Article 9(2) thereof, 
Whereas: 
(1)  Regulation (EC) No 1831/2003 provides for the author isation of additives for use in animal nutr ition and for the 
grounds and procedures for granting such author isation. Article 10 of that Regulation provides for the re- 
evaluation of additives author ised pursuant to Council Directive 70/524/EEC (2). 
(2)  1,1-Dimetho xy-2-pheny lethane, pheneth yl format e, pheneth yl octanoat e, pheneth yl isobutyrate , pheneth yl 
2-methyl -butyrate and phenethyl benzoate (‘the substances concer ned’) were author ised without a time limit in 
accordance with Directive 70/524/EEC as feeds additives for all animal species. Those products were subsequently 
entered in the Register of feed additives as existing products, in accordance with Article 10(1) of Regulation (EC) 
No 1831/2003. 
(3)  In accordance with Article 10(2) of Regulation (EC) No 1831/2003 in conjunction with Article 7 thereof, an 
application was submitted for the re-evaluation of the substances concer ned as feed additives for all animal 
species. The applicant requested those additives to be classified in the additive categor y ‘sensor y additives ’. That 
application was accompan ied by the particulars and documents required under Article 7(3) of Regulation (EC) 
No 1831/2003. 
(4)  The European Food Safety Auth ority (‘the Author ity’) concluded in its opinion of 7 Marc h 2012 (3) that, under 
the proposed conditions of use in feed, the substances concer ned do not have adverse effects on animal health, 
human health or the environment. The Auth ority further concluded that the function of the substances 
concer ned in feed is similar to that on food. The Auth ority has already concluded that for food those substances 
are efficacious, as they increase the food smell or palatability . Theref ore, that conclusion can be extrapolated for 
feed. As the use of the substances concer ned in wate r for drinking is difficult to control when used simultan ­
eously with feed such use should be excl uded. However , those substances can be used within compo und feeds 
whic h are subsequently administe red via water . 
(5)  Restr ictions and conditions should be provided for to allow better control. Since safety reasons do not require the 
setting of a maximum content and taking into account the re-evaluation performe d by the Authority, 
recommended cont ents should be indicated on the label of the additive. Where such cont ents are excee ded, 
certain information should be indicated on the label of premixtures, compound feeds and feed mate rials. 
(6)  The Auth ority concluded that the substances concer ned are considered as irritant to eyes and respirato ry tract, 
skin sensitisers and harmful if swallo wed. Consequently , appropr iate protective measures should be taken. The 
Author ity does not consider that there is a need for specifi c requirements of post-market monitori ng. It also 
verified the repor t on the method of analysis of the feed additives in feed submitte d by the Reference Laborat ory 
set up by Regulation (EC) No 1831/2003. 
(7)  The assessment of the substances concer ned shows that the conditions for author isation, as provided for in 
Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of those substances should be 
author ised as specified in the Annex to this Regulation. 17.1.2017 L 13/167 Official Jour nal of the European Union EN     
(1)OJ L 268, 18.10.2003, p. 29. 
(2)Council Directive 70/524/EEC of 23 November 1970 concer ning additives in feed ing-stuffs (OJ L 270, 14.12.1970, p. 1). 
(3)EFSA Jour nal 2012;10(3):2625. (8) Since safety reasons do not require the immediate application of the modifi cations to the conditions of author is­
ation for the substances concer ned, it is appropr iate to allow a transitional period for interest ed parties to 
prepare themselves to meet the new requirements resulting from the author isation. 
(9)  The measures provided for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed, 
HAS ADOPTED THIS REGUL ATION: 
Article 1 
Author isation 
The substances specifi ed in the Annex, belonging to the additive catego ry ‘sensor y additives ’ and to the functional group 
‘flavouri ng compounds’, are author ised as feed additives in animal nutr ition subject to the conditions laid down in that 
Annex. 
Article 2 
Transitional measures 
1. The substances as specified in the Annex and premixtures containing those substances, which are produced and 
labelled before 6 August 2017 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stoc ks are exhausted. 
2. Com pound feed and feed mater ials containing the substances as specif ied in the Annex which are produced and 
labelled before 6 Febr uary 2018 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stoc ks are exhausted if they are intende d for food-producing animals. 
3. Com pound feed and feed mater ials containing the substances as specif ied in the Annex which are produced and 
labelled before 6 Febr uary 2019 in accordance with the rules applicable before 6 Febr uary 2017 may continue to be 
placed on the mark et and used until the existing stocks are exhaust ed if they are intende d for non-f ood-producing 
animals. 
Article 3

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the 
European Union. 
This Regulation shall be binding in its entirety and directly applicable in all Member State s.
