Translate the following English sentence to French:
"This is why it is essential to approve Amendment No 2 to Recital 4 which avoids the risks of the monopoly which would arise if companies which were the first to be authorised to place an additive on the market were to remain the only ones able to continue marketing it during the re-evaluation procedure."
C'est pourquoi il est important d'accepter l'amendement 2 au considérant 4, qui permet d'éviter le risque de monopole si les sociétés qui ont déjà été les premières autorisées à mettre un additif sur le marché restaient les seules à pouvoir l'exploiter pendant la période de réévaluation.
