THE EUR OPEAN COMMISSION,
Havi ng regar d to the Treaty on the Functioning of the European Union,
Havi ng rega rd to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 Sept ember 2003 on 
additives for use in animal nutr ition (1), and in particular Article 9(2) thereof,
Whereas:
(1) Regulation (EC) No 1831/2003 provid es 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(2) of that Regulation provides for the 
re-evaluation of additives author ised pursuant to Council Directive 70/524/EEC (2).
(2) The substances ethyl heptanoate, ethyl 2-methyl butyrate, isopentyl acetate , 3-methylbutyl 3-methylbutyrat e, 
2-methyl propionic acid, 3-methyl butyl butyrat e, 2-meth ylbutyl acetate , hex-2-en-1-ol, hex-2(trans)-enal, allyl 
hexanoate, allyl hept anoate, linalool, 2-methyl -1-phenylpropan-2-ol, alpha-ionone, beta-damascone, nootkat one, 
beta-ionone, alpha-irone, beta-damascenone, (E)-beta-damascone, pentadecano-1,15-lactone, 2-phenylethan-1-ol, 
pheneth yl isovalerate, 4-(p-hydr oxyphenyl) butan-2-one, 2-metho xynaphthalene, 2-isoprop yl-4-meth ylthiazole and 
valencene were author ised without a time limit in accordance with Directive 70/524/EEC as feed additives for all 
animal species. Those substances were subsequently entered in the Register of Feed Additives as existing products 
belonging to the functional group of flavouri ng compo unds, in accordance with Article 10(1), point (b), 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, several 
applications were submitted for the author isation of the abov e-mentioned substances as feed additives for all animal 
species. The applicant requeste d the additives to be classified in the additive categor y ‘sensor y additives ’ and in the 
functional group ‘flavouring compo unds ’. The applications were accompanied by the particulars and documents 
required under Article 7(3) of Regulation (EC) No 1831/2003.
(4) The applicant requeste d the additives to be author ised for use also in water for drinking. However , Regulation 
(EC) No 1831/2003 does not allow the author isation of ‘flavouring compo unds ’ for use in water for drinking. 
Theref ore, the applicant withdrew the application for water for drinking for all the substances concer ned.
(1)OJ L 268, 18.10.2003, p. 29.
(2)Council Directive 70/524/EEC of 23 November 1970 concer ning additives in feedingstuffs (OJ L 270, 14.12.1970, p. 1).EN Offi cial Jour nal of the European Union L 74/10 13.3.2023  (5) The European Food Safety Author ity (‘the Auth ority’) concluded in its opinions of 7 March 2012 (3), 25 Apr il 
2012 (4), 17 October 2012 (5)(6), 13 Novem ber 2012 (7), 12 March 2013 (8), 10 Marc h 2015 (9), 8 Marc h 2016 (10), 
20 Apr il 2016 (11), 12 July 2016 (12), 28 Febr uary 2019 (13), 18 November 2020 (14)and 23 March 2022 (15)that, 
under the proposed conditions of use, the substances do not have adverse effects on animal health, consumer safety 
or the environment. The Authority concluded that for 2-methyl -1-phenylpropan-2-ol, beta-damascone, alpha-irone, 
(E)-beta-damascone, pheneth yl isovalerate, 4-(p-hydro xyphenyl) butan-2-one, and 2-isoprop yl-4-methylthiazole, the 
safe use level for the mar ine environment is estimat ed to be 0,05 mg/kg feed.
(6) The Auth ority also concluded that all the substances should be considered as irritants to skin and eyes and as 
poten tial skin and respirato ry sensitisers in suscep tible individuals. In the absence of data for hex-2-en-1-ol, hex-2 
(trans)-enal, allyl hexanoate and allyl heptanoat e, the Author ity could not conclude that users can safely handle 
those substances. However , the applicant, as required, produced a safety data sheet where hazards for users have 
been identified for those substances. The hazards descr ibed in the safety data sheet were, in particular , hazards for 
skin, eye contact and respirator y exposure for hex-2(trans)-enal, hazards for skin and eye contact for hex-2-en-1-ol 
and allyl hept anoate and harmful if swallo wed and toxic in contact with skin for allyl hexanoate.
(7) The Author ity finally concluded that all substances are recognised to flavour food and their function in feed would 
be essentially the same as that in food. Theref ore, no further demonstration of efficacy is considered necessar y. It 
also verified the repor t on the methods of analysis of the feed additives in feed submitted by the Reference 
Laboratory set up by Regulation (EC) No 1831/2003.
(8) The assessment of all the substances shows that the conditions for author isation, as provid ed for in Article 5 of 
Regulation (EC) No 1831/2003, are satisfi ed. According ly, the use of those substances should be author ised. The 
Commission considers that appropr iate prot ective measures should be take n to prevent adverse effects on human 
health, in particular as regards the users of the additive.
(9) Certain conditions should be provid ed for to allow better control. In particular , a recommended maximum content 
should be indicated on the label of the feed additives. Where such cont ent is exceed ed, certain information should 
be indicated on the label of premixtures.
(10) The fact that the substances are not author ised for use as flavouri ngs in water for drinking does not preclude their 
use in compo und feed which is administe red via water .
(11) Since safet y reasons do not require the immediate application of the modifications to the conditions of author isation 
of the substances concer ned, it is appropr iate to provide for a transitional period for the interested parties to prepare 
themselves to meet the new requirements resulting from the author isation.
(12) The measures provid ed for in this Regulation are in accordance with the opinion of the Standing Committ ee on 
Plants, Animals, Food and Feed,
