(Text with EEA relevance)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European Union,  
Having regard to Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 
on additives for use in animal nutrition (  1 ), and in particular Article 9(2) thereof,  
Whereas:  
(1)  Regulation (EC) No 1831/2003 provides for the authorisation of additives for use in animal nutrition and for the 
grounds and procedures for granting such authorisation. Article 10(2) of that Regulation provides for the re- 
evaluation of additives authorised pursuant to Council Directive 70/524/EEC (  2 ). 
(2)  The substances ethyl oleate, nona-2,6-dien-1-ol, pent-2-en-1-ol, trans-2,cis-6-nonadien-1-ol, 2-dodecenal, nona-2 
(trans),6(cis)-dienal, nona-2,4-dienal, trans-2-nonenal, 2,4-decadienal, hepta-2,4-dienal, deca-2(trans),4(trans)- 
dienal, dodec-2(trans)-enal, hept-2(trans)-enal, non-2-enal, nona-2(trans),6(trans)-dienal, undec-2(trans)-enal, 
trans-2-octenal, trans-2-decenal, tr-2, tr-4-nonadienal, tr-2, tr-4-undecadienal, hex-2(trans)-enyl acetate, hex-2- 
enyl butyrate, oct-1-en-3-one, isopulegol, 4-terpinenol, linalyl butyrate, linalyl formate, linalyl propionate, 
linalyl isobutyrate, 3-methyl-2-cyclopenten-1-one, methyl 3-oxo-2-pentyl-1-cyclopentylacetate, benzophenone, 
benzyl cinnamate, ethyl salicylate, 1,2-dimethoxy-4-(prop-1-enyl)-benzene, myrcene and β-ocimene were auth ­
orised 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 flavouring compounds, 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 authorisation of the above-mentioned substances as feed additives for all 
animal species. The applicant requested the additives to be classified in the additive category ‘sensory additives’ 
and in the functional group ‘flavouring compounds’. The applications were accompanied by the particulars and 
documents required under Article 7(3) of Regulation (EC) No 1831/2003.EN  21.3.2023 Official Journal of the European Union L 82/1  
( 1 ) OJ L 268, 18.10.2003, p. 29.  
( 2 ) Council Directive 70/524/EEC of 23 November 1970 concerning additives in feedingstuffs (OJ L 270, 14.12.1970, p. 1). (4)  The applicant requested the additives to be authorised for use also in water for drinking. However, Regulation 
(EC) No 1831/2003 does not allow the authorisation of ‘flavouring compounds’ for use in water for drinking. 
Therefore, the applicant withdrew the application for water for drinking for all the substances concerned.  
(5)  The European Food Safety Authority (‘the Authority’) concluded in its opinions of 25 April 2012 (  3 ), 
13 June 2012 (  4 ), 13 November 2012 (  5 ), 12 March 2013 (  6 ), 1 December 2015 (  7 ), 20 April 2016 (  8 ), 
28 February 2019 (  9 ), 10 January 2020 (  10 ), 28 January 2020 (  11 ) and 23 March 2022 (  12 ) that, under the 
proposed conditions of use, the substances do not have adverse effects on animal health, consumer safety or 
the environment. In the absence of relevant studies, the Authority could not conclude on the safety for the users 
when handling the additives concerned, or concluded that the substances should be considered as irritants to skin 
and eyes and as potential skin and respiratory sensitisers.  
(6)  The Authority concluded that all the substances concerned are recognised to flavour food and their function in 
feed would be essentially the same as that in food. Therefore, no further demonstration of efficacy is considered 
necessary. It also verified the report on the methods of analysis of the feed additives in feed submitted by the 
Reference Laboratory set up by Regulation (EC) No 1831/2003.  
(7)  The assessment of all the substances concerned shows that the conditions for authorisation, as provided for in 
Article 5 of Regulation (EC) No 1831/2003, are satisfied. Accordingly, the use of those substances should be 
authorised. The Commission considers that appropriate protective measures should be taken to prevent adverse 
effects on human health, in particular as regards the users of the additive.  
(8)  Certain conditions should be provided for to allow better control. In particular, a recommended maximum 
content should be indicated on the label of the additives. Where such content is exceeded, certain information 
should be indicated on the label of premixtures.  
(9)  The fact that the substances concerned are not authorised for use as flavourings in water for drinking does not 
preclude their use in compound feed which is administered via water.  
(10)  Since safety reasons do not require the immediate application of the modifications to the conditions of author ­
isation of the substances concerned, it is appropriate to provide for a transitional period for the interested parties 
to prepare themselves to meet the new requirements resulting from the authorisation.  
(11)  The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on 
Plants, Animals, Food and Feed,  
HAS ADOPTED THIS REGULATION:
