of 14 December 2016 
concer ning the author isation of octan-2-ol, isopropanol, penta n-2-ol, octa n-3-ol, heptan-2-one,

(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)  Octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2 -one, pentan-2-one, 6-meth yl-hepta-3,5-dien-2-one, 
nonan-3-one, decan-2-one and isoprop yl tetradecanoate were author ised without a time limit in accordance with 
Directive 70/524/EEC as feed additives for all animal species. Those products were subsequently entered in the 
Regist er 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 octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2 -one, 
pentan-2-one, 6-meth yl-hepta-3,5-dien-2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoat e as feed 
additives for all animal species. The applicant request ed those additives to be classif ied in the additive 
catego ry ‘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 20 October 2015 (3) that, 
under the proposed conditions of use in feed octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2 -one, 
pentan-2-one, 6-meth yl-hepta-3,5-dien-2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoate do not have 
adverse effects on animal health, human health or the environment. The Author ity further concluded that the 
function of octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2-one, pentan-2-one, 6-meth yl-hepta-3,5- 
dien-2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoate in feed is similar to that on food. The Authority 
has already concluded that for food those substances are efficacious, as it increases the food smell or palatability . 
The Author ity could not conclude on the safety of octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2 - 
one, pentan-2-one, 6-methyl - hepta -3,5-dien-2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoate used in 
water for drinking. However , those substances can be used within a compound feed subsequently administered 
via wate r. 
(5)  Restr ictions and conditions should be provided for to allow better control. For practical reasons and taking into 
account the re-evaluation performe d by the Author ity, maximum recommended cont ents should be set up. 
Where the recommended conte nt of the additive in compl ete feedingstuff is exceed ed, the identif ication number 
of the feed additive, its name and added amount should be indicated on the label of premixtures, compo und 
feeds and feed mater ials 17.1.2017 L 13/112 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 2015;13(11):4268. (6)  The Author ity concluded that in the absence of data on user safet y, octan-2-ol, isopropanol, pentan-2-ol, octan- 
3-ol, heptan-2-one, pentan-2-one, 6-methyl - hept a-3,5-dien- 2-one, nonan-3-one, decan-2-one, isoprop yl tetrade­
canoat e should be considered as irritant to skin, eyes and respirato ry tract and as a skin sensitiser . Consequently , 
appropr iate prote ctive measures should be taken. The Author ity does not consider that there is a need for 
specific requirements of post-market monitor ing. It also verified the repor t on the method of analysis of the feed 
additives in feed submitt ed by the Reference Laboratory set up by Regulation (EC) No 1831/2003. 
(7)  The assessment of octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2-one, pentan-2-one, 6-methyl -hepta- 
3,5-dien-2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoate shows that the conditions for author isation, 
as provided for in Article 5 of Regulation (EC) No 1831/2003, are satisfi ed. According ly, the use of those 
substances should be author ised as specifi ed in the Annex to this Regulation. 
(8) Since safety reasons do not require the immediate application of the modifi cations to the conditions of author is­
ation for octan-2-ol, isopropanol, pentan-2-ol, octan-3-ol, heptan-2-one, pentan-2-one, 6-methyl-hep ta-3,5-dien- 
2-one, nonan-3-one, decan-2-one, isoprop yl tetradecanoate it is appropr iate to allow a transitional period for 
inter ested 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
