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 butyr ic acid, ethyl butyrate, ethyl isobutyrate, ethyl isovaler ate, meth yl isovalera te, 2-methyl- 
2-pente noic acid, 6-meth ylhept-5-en-2-one, undecan-2-one, octan-2-one, nonan-2-one, octan-3-one, tridecan- 
2-one, 5-methyl hept-2-en -4-one, dodecano-1,5-lact one, tetradecano-1,5-lact one, 5-methyl furfural, 4-phen ylbut- 
3-en-2-one, p-anisyl alcohol, 4-metho xybenzaldehyde, piperonal, vanillin, p-anisyl acetate , benzyl benzoate, 
isobutyl salicylate, isopentyl salicylate, benzyl salicylate and diphen yl ether 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 Registe r 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 requested 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 ‘flavouri ng compounds’ 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 6.7.2023 L 171/11  (5) The European Food Safety Authority (‘the Author ity’) concluded in its opinions of 25 Apr il 2012 (3), 13 June 
2012 (4), 26 October 2012 (5), 12 March 2013 (6), 20 October 2015 (7), 26 Januar y 2016 (8), 25 May 2016 (9), 
10 Januar y 2020 (10), 28 Januar y 2020 (11)and 7 Januar y 2023 (12)that, under the proposed conditions of use, the 
substances concer ned are safe for all animal species, consumers and the envi ronment.
(6) The Author ity also indicated that the safety data sheets required in accordance with Regulation (EC) No 1907/2006 
of the European Parliament and of the Council (13)demonstrate that for butyr ic acid, ethyl butyrate , ethyl 
isobutyrate, ethyl isovaler ate, meth yl isovalera te and 2-meth yl-2-pentenoic acid, 6-meth ylhept-5-en-2-one, 
undecan-2-one, octan-2-one, nonan-2-one, octan-3-one, tridecan-2-one, for dodecano-1,5-lactone, tetradeca ­
no-1,5-lact one, p-anisyl alcohol, 4-metho xybenzaldehyde, piperonal, vanillin, p-anisyl acetate , benzyl benzoate, 
isobutyl salicylate, isopentyl salicylate , benzyl salicylate and diphen yl ether some hazards are identif ied for skin and 
eye contact and respirato ry exposure. As regar ds 5-methyl hept-2-en-4-one, 5-meth ylfur fural and 4-phenylbut-3-en- 
2-one, the Author ity concluded that due to the lack of new evidence on the effects of those additives on the 
respirato ry system, skin and eyes it is not in a position to conclude on the safety for the use of those three 
substances.
(7) The Author ity finally concluded that all the substances concer ned 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. The Authority considered that there was no need for specific requirements of post-market monitori ng. It 
also chec ked 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) 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.
(9) The fact that the substances concer ned are not author ised for use as flavourings in wate r for drinking does not 
preclude their use in compo und feed which is administe red via wate r.
(10) The assessment of all the substances concer ned shows that the conditions for author isation, as provid ed for in 
Article 5 of Regulation (EC) No 1831/2003, are satisfied. According ly, the use of those substances should be 
author ised. In addition, the Commission considers that appropr iate protective measures should be taken to prevent 
adverse effects on the health of the users of the additives.
(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,
