3c363 — L-arginine Additive composition Powder with a minimum content of L-arginine of 98 % (on a dry matter basis) and a maximum content of 1,5 % water Characterisation of the active substance L-arginine ((S)-2-amino-5-guanidinopentanoic acid) produced by fermentation with Escherichia coli NITE BP-02186. Chemical formula: C6H14N4O2 CAS number: 74-79-3 Analytical method (1) For the identification of L-arginine in the feed additive: — Food Chemical Codex ‘L-arginine monograph’ For the quantification of arginine in the feed additive and water: — ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS) For the quantification of arginine in premixtures, compound feed and feed materials: — ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS) – Commission Regulation (EC) No 152/2009 All animal species 1. L-arginine may be placed on the market and used as an additive consisting of a preparation. 2. The additive can be also used via water for drinking. 3. In the directions for use of the additive and premixture, the storage conditions, the stability to heat treatment and the stability in water for drinking shall be indicated. 4. The moisture content shall be indicated on the label of the additive. 5. Declaration to be made on the label of the additive and premixture: ‘The supplementation with L-arginine, in particular via water for drinking, should take into account all essential and conditional essential amino acids in order to avoid imbalances.’ 6. For users of the additive and premixture, feed business operators shall establish operational procedures and organisational measures to address potential risks by inhalation. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixture shall be used with personal protective equipment, including breathing protection. 24 January 2029
