Preparation of carvacrol, thymol, D-carvone, methyl salicylate and L-menthol

What it is. Zootechnical additive consisting of an encapsulated solid preparation combining carvacrol, thymol, D-carvone, methyl salicylate and L-menthol, together with amorphous silica and hydrogenated vegetable oil as carriers. Each active substance is present within a defined concentration range, and the solid encapsulated form is intended to protect the compounds and control their release.

What it is for. This type of blend of essential-oil-derived compounds is generally used to support gut function and performance in poultry. It is authorised for chickens for fattening, chickens and minor poultry species reared for laying, turkeys for fattening, turkeys reared for breeding, and minor poultry species for fattening or breeding, within the "other zootechnical additives" functional group. Minimum content levels are set in the regulation; use should follow the premixture and feed instructions.

Points to watch. Storage conditions and heat-treatment stability must be stated in the instructions for use of the additive and premixtures. It must not be combined with other sources of carvacrol, thymol, D-carvone, methyl salicylate or L-menthol, and operators must put in place procedures and, where needed, personal protective equipment (skin and eye protection) to manage handling risks.
